<ch_section>New and Noteworthy</ch_section>
<ch_category>Test plan creation and debugging improvements</ch_category>
<ch_title>New Search Feature in View Results Tree to allow searching for text / regexp in Request/Responses/Headers/Cookies/&hellip; This will ease correlation and Test plans creation</ch_title>
<figure width="846" height="613" image="changes/3.0/view_results_tree_search_feature.png"></figure>
<ch_title>New JSON Post Processor to better extract data from JSON content using user friendly JSON-PATH syntax</ch_title>
<p>JSON is now a first class citizen in JMeter with the introduction of a new <a href="http://goessner.net/articles/JsonPath/" target="_blank">JSONPath</a> post processor.
This post processor is very similar to Regular Expression Post Processor but is well suited for JSON code.
It is based on <a href="https://github.com/jayway/JsonPath" target="_blank" >Jayway JSON Path library</a> </p>
<figure width="829" height="223" image="changes/3.0/json_path_extractor.png" ></figure>
<ch_title>New validation feature, in one click run a selection of Thread Groups with <code>1</code> user, no pause and <code>1</code> iteration</ch_title>
<figure width="295" height="629" image="changes/3.0/thread_group_validate.png"></figure>
<ch_title>JSR223 Test Elements do not require a Cache Compilation Key anymore</ch_title>
<p>Just check <code>Cache compiled script if available</code> checkbox and the elements (Pre-Processor, Post-Processor, Assertions, Listeners, &hellip;)
will pre-compile the script and cache the compiled code if the underlying language supports it</p>
<figure width="991" height="606" image="changes/3.0/jsr223_cache_compiled.png"></figure>
<ch_title>Nashorn can now be used as Javascript engine providing better performance and easier usage</ch_title>
To enable <a target="_blank" href="http://www.oracle.com/technetwork/articles/java/jf14-nashorn-2126515.html" >Nashorn</a>, you need to set in <code>user.properties</code>:
<source>javascript.use_rhino=false</source>
<p>Nashorn can be used with Java 8 in the following elements:
</p>
<ul>
<li>IfController</li>
<li>JSR223 Test elements with <code>javascript</code> language selected</li>
<li><code>__javaScript</code> function</li>
</ul>
<ch_title>Jexl3 has been integrated. It provides new scripting features and much better documentation</ch_title>
<a href="http://commons.apache.org/proper/commons-jexl/" target="_blank">JEXL3</a> can now be used thanks to a new function <code>__jexl3</code>.
JEXL is a language very similar to JSTL.
<ch_title>Simplified HTTP Request UI</ch_title>
<p>A new "<code>Advanced</code>" tab has been added to HTTP Request to simplify configuration. The file upload feature has been moved into a dedicated tab.
This increases the space available for parameters in UI and simplifies the UX.</p>
<figure width="895" height="674" image="changes/3.0/http_request_basic.png"></figure>
<figure width="880" height="299" image="changes/3.0/http_request_advanced.png"></figure>
<ch_title>HTTP Request Defaults improvements</ch_title>
<p>You can now configure Source Address (IP Spoofing like feature) and "<code>Save response as MD5 hash</code>" in Advanced Tab
</p>
<figure width="893" height="259" image="changes/3.0/http_request_defaults_advanced.png" ></figure>
<ch_category>Reporting improvements</ch_category>
<ch_title>New Reporting Feature generating dynamic Graphs in HTML pages (APDEX, Summary report and Graphs)</ch_title>
<p>A dynamic HTML report can now be generated either at the end of a load test or from a result file whenever you want.
See <a href="./usermanual/generating-dashboard.html" target="_blank">Generating dashboard</a> for more details.
This report provides the following metrics:
</p>
<ul>
<li><a href="https://en.wikipedia.org/wiki/Apdex" target="_blank">APDEX</a> (Application Performance Index) table that computes the APDEX based on configurable values for tolerated and satisfied thresholds</li>
<li>A request summary graph showing the Success and failed transaction percentage: <figure width="1658" height="650" image="changes/3.0/report_apdex_and_summary.png" ></figure></li>
<li>A Statistics table providing in one table a summary of all metrics per transaction including 3 configurable percentiles : <figure width="1376" height="433" image="changes/3.0/report_statistics.png" ></figure></li>
<li>An error table providing a summary of all errors and their proportion in the total requests : <figure width="1344" height="455" image="changes/3.0/report_errors.png" ></figure></li>
<li>Zoomable chart where you can check/uncheck every transaction to show/hide it for:

<ch_title>BackendListener now allows you to define sampler list as a regular expression</ch_title>
<p>You can now use a regular expression to select the samplers you want to filter.
Use parameter: <code>useRegexpForSamplersList=true</code> and put a regex in pararameter <code>samplersList</code>
</p>
<figure width="806" height="380" image="changes/3.0/graphite_backend_listener_regex.png" ></figure>
<ch_category>Protocols and Load Testing improvements</ch_category>
<ch_title>Migration to HttpClient 4.5.2 has been started. Although not completely finished, it improves many areas in JMeter</ch_title>
<p>Migration to HttpClient 4.5.2 improves the following fields of JMeter:
</p>
<ul>
<li>Support of recent RFC like <a href="https://tools.ietf.org/html/rfc6265" target="_blank">HTTP State Management Mechanism RFC-6265 for Cookies</a>, you should use now <code>HC4CookieHandler</code> in HTTP Cookie Manager component and select <code>standard</code> Cookie policy</li>
<li><a href="https://en.wikipedia.org/wiki/Server_Name_Indication" target="_blank">Server Name Indication (SNI)</a> support for HttpClient4 implementation</li>
<li>Improved and better performing validation mechanism for Stale connections and Keep-Alive management, see properties <code>httpclient4.validate_after_inactivity</code> and <code>httpclient4.time_to_live</code></li>
<li>Many bug fixes since previous version 4.2.6 used in JMeter 2.13, see <a href="http://www.apache.org/dist/httpcomponents/httpclient/RELEASE_NOTES-4.5.x.txt" target="_blank">HttpClient 4.5.X release notes</a></li>
<li>Better support of HTTP RFC 2616 / RFC 7230 and fixes to issues with <code>deflate</code> compression management</li>
</ul>
<ch_title>Parallel Downloads is now realistic and scales much better:</ch_title>
<ul>
<li>Parsing of CSS imported files (through <code>@import</code>) or embedded resources (background, images, &hellip;)</li>
<li>Lazy initialization of SSL context: For 15 Threads 138% more sampling in 5 minutes for HTTP only tests. Gain increases as number of threads increases</li>
<li>Rework of Connection management for Parallel Download: This better simulates current browser behaviour and improves throughput. For 15 Threads 135% extra samples in 5 minutes.</li>
<li>Reuse of Threads used for Parallel downloads through a ThreadPool: This improves throughput and increases JMeter scalability for such tests</li>
<li>Total of 750% more throughput found on test with 15 threads, the more threads you have the more the gain</li>
<li>You can now compute and store just the MD5 of embedded resources instead of storing the entire response, this can be done by setting the property <code>httpsampler.embedded_resources_use_md5=true</code></li>
</ul>
<ch_title>Introduction of Sample Timeout feature</ch_title>
<p>This new <complink name="Sample Timeout"/> Pre-Processor allows you to apply a Timeout on the elements that are in its scope.
In the screenshot below the 10 second timeout applies to the <code>Debug Sampler</code> and <code>HTTP Request</code> elements.
</p>
<figure width="828" height="161" image="changes/3.0/sample_timeout.png" ></figure>
<ch_title>JDBC request now uses DBCP2 pool</ch_title>
<p>JDBC Request and JDBC Connection Configuration have been updated to replace old Excalibur Pool by Apache Commons DBCP2 pool. As a consequence properties have been migrated to equivalent
when available and UI has been updated.
Note that unlike Excalibur, Commons DBCP uses the validation query when creating the pool.
So make sure the query is valid.
The default query suits many databases, but not all - for example Oracle requires '<code>SELECT 1 FROM DUAL</code>' or similar.
</p>
<figure width="582" height="434" image="changes/3.0/jdbc_connection_configuration.png" ></figure>
<ch_category>UX Improvements:</ch_category>
<ch_title>Better display in HiDPI screens</ch_title>
<p>See <a href="usermanual/hints_and_tips.html#hidpi">JMeter with a HiDPI screen on Linux or Windows</a> in Hints and Tips section in user manual</p>
<ch_title>New Icon look and Logo</ch_title>
<p>JMeter has a new Logo created by Felix Schumacher. <br/>Icons have also been refreshed to give a more modern style and make them more meaningful</p>
<ch_title>Lots of fixes of annoying little bugs</ch_title>
<p>Around 40 UI fixes have been made to either fix buggy, confusing behaviour or simplify usage by not allowing incompatible options to be selected</p>
<ch_title>Improved Thread Group UI and related actions (<code>Start</code>, <code>Start No Timers</code>, <code>Validate</code>)</ch_title>
<p>
Creating and testing a Test Plan before Load Test has been much simplified by allowing you to only start a selection of Thread Group, start them without applying Timers (thus gaining time)
or start them using a new Validation mode. This validation mode allows you to start a Thread Group (without modifying it) with 1 thread, 1 iteration and without applying timers.
This validation mode can be customized.
</p>
<figure width="302" height="235" image="changes/3.0/thread_group_starters.png" ></figure>
<ch_title>New shortcuts</ch_title>
<ul>
<li>Add most used elements
(<keycombo>
<keysym>Ctrl</keysym>
<keysym>0</keysym>
</keycombo>
&hellip;
<keycombo>
<keysym>Ctrl</keysym>
<keysym>9</keysym>
</keycombo>),
configurable through <code>gui.quick_<em>XXX</em></code> properties</li>
<li>Shortcuts to expand nodes</li>
</ul>
<ch_category>Core improvements</ch_category>
<ch_title>Configuration simplification with better defaults</ch_title>
<p>Default values for many properties have been modified to make JMeter configuration optimal Out of the box. Read "Incompatible changes" section for more details.</p>
<ch_title>Apache Groovy bundled with JMeter</ch_title>
<p><a href="http://www.groovy-lang.org/" target="_blank">Apache Groovy</a>, the well-known JVM scripting language, is now bundled with Apache JMeter in lib folder.
This allows you to use it immediately through JSR223 Elements by selecting the Groovy language.</p>
<ch_title>Superflous and old properties removed</ch_title>
<p>Old properties that existed to maintain backward compatibility or to offer some superflous customization have been removed.
Read "Incompatible changes" section to see which properties have been removed.</p>
<ch_title>Code and documentation improvements</ch_title>
<ul>
<li>Migration to Java7 source code and use of its syntactic sugar</li>

<li>Better management of Headless tests</li>
<li>More Unit Tests</li>
</ul>
<ch_title>Dependencies refresh</ch_title>
<p>

<li>In RandomTimer class, protected instance <code>timer</code> field has been replaced by <code>getTimer()</code> protected method, this is related to <bugzilla>58100</bugzilla>. This may impact 3<sup>rd</sup> party plugins.</li>
<li>Since version 3.0, you can use Nashorn Engine (default javascript engine is Rhino) under Java8 for Elements that use Javascript Engine (<code>__javaScript</code>, <code>IfController</code>). If you want to use it, use property <code>javascript.use_rhino=false</code>, see <bugzilla>58406</bugzilla>.
<note>Note: in a future version, we will switch to Nashorn by default. Users are encouraged to report any issue related to using Nashorn instead of Rhino.</note>
</li>
<li>Since version 3.0, JMS Publisher will reload contents of file if Message source is "<code>From File</code>" and the "<code>Filename</code>" field changes (e.g. if it uses a variable that has changed)</li>
<li>org.apache.jmeter.gui.util.ButtonPanel has been removed, if you use it in your 3<sup>rd</sup> party plugin or custom development ensure you update your code. See <bugzilla>58687</bugzilla></li>
<li>Property <code>jmeterthread.startearlier</code> has been removed. See <bugzilla>58726</bugzilla></li>
<li>Property <code>jmeterengine.startlistenerslater</code> has been removed. See <bugzilla>58728</bugzilla></li>

<!-- =================== Known bugs or issues related to JAVA Bugs =================== -->
<ch_section>Known problems and workarounds</ch_section>
<ul>
<li>The Once Only controller behaves correctly under a Thread Group or Loop Controller,
but otherwise its behaviour is not consistent (or clearly specified).</li>
<li>
The numbers that appear to the left of the green box are the number of active threads / total number of threads,
the total number of threads only applies to a locally run test, otherwise it will show <code>0</code> (see <bugzilla>55510</bugzilla>).
</li>
<li>
Note that there is a <a href="http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6396599 ">bug in Java</a>
on some Linux systems that manifests itself as the following error when running the test cases or JMeter itself:
<source>
[java] WARNING: Couldn't flush user prefs:
java.util.prefs.BackingStoreException:
java.lang.IllegalArgumentException: Not supported: indent-number
</source>
This does not affect JMeter operation. This issue is fixed since Java 7b05.
</li>
<li>
Note that under some windows systems you may have this WARNING:
<source>
java.util.prefs.WindowsPreferences
WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0
x80000002. Windows RegCreateKeyEx(&hellip;) returned error code 5.
</source>
The fix is to run JMeter as Administrator, it will create the registry key for you, then you can restart JMeter as a normal user and you won't have the warning anymore.
</li>
<li>
With Oracle Java 7 and Mac Book Pro Retina Display, the JMeter GUI may look blurry.
This is a known Java bug, see Bug <a href="http://bugs.java.com/bugdatabase/view_bug.do?bug_id=8000629" >JDK-8000629</a>.
A workaround is to use a Java 7 update 40 runtime which fixes this issue.
</li>
<li>
You may encounter the following error:
<source>java.security.cert.CertificateException: Certificates does not conform to algorithm constraints</source>
if you run a HTTPS request on a web site with a SSL certificate (itself or one of SSL certificates in its chain of trust) with a signature
algorithm using MD2 (like md2WithRSAEncryption) or with a SSL certificate with a size lower than 1024 bits.
This error is related to increased security in Java 7 version u16 (MD2) and version u40 (Certificate size lower than 1024 bits), and Java 8 too.
<br></br>
To allow you to perform your HTTPS request, you can downgrade the security of your Java installation by editing
the Java <code>jdk.certpath.disabledAlgorithms</code> property. Remove the MD2 value or the constraint on size, depending on your case.
<br></br>
This property is in this file:
<source>JAVA_HOME/jre/lib/security/java.security</source>
See <bugzilla>56357</bugzilla> for details.
</li>
<li>
Under Mac OSX Aggregate Graph will show wrong values due to mirroring effect on numbers.
This is due to a known Java bug, see Bug <a href="https://bugs.openjdk.java.net/browse/JDK-8065373" >JDK-8065373</a>
The fix is to use JDK7_u79, JDK8_u45 or later.
</li>
<li>
View Results Tree may fail to display some HTML code under HTML renderer, see <bugzilla>54586</bugzilla>.
This is due to a known Java bug which fails to parse "<code>px</code>" units in row/col attributes.
See Bug <a href="https://bugs.openjdk.java.net/browse/JDK-8031109" >JDK-8031109</a>
The fix is to use JDK9 b65 or later.
</li>
<li>
JTable selection with keyboard (<keycombo><keysym>SHIFT</keysym><keysym>up/down</keysym></keycombo>) is totally unusable with JAVA 7 on Mac OSX.
This is due to a known Java bug <a href="https://bugs.openjdk.java.net/browse/JDK-8025126" >JDK-8025126</a>
The fix is to use JDK 8 b132 or later.

<ch_category>New Elements</ch_category>
<ch_title>New Async BackendListener with Graphite implementation</ch_title>
<p>A new Async BackendListener has been added to allow sending result data to a backend listener.
JMeter ships with a GraphiteBackendListenerClient that allows sending results to a <a href="http://graphite.wikidot.com/" target="_blank">Graphite</a> server using Pickle or Plaintext protocols.
You can implement your own backend by extending <a href="./api/org/apache/jmeter/visualizers/backend/AbstractBackendListenerClient.html">AbstractBackendListenerClient</a>. This backend could be
a database (JDBC), a Message Oriented Middleware (JMS), a Webservice or anything you want.

<ch_category>Core Improvements</ch_category>
<ch_title>New connect time metric</ch_title>
<p>Starting with this version a new metric called connectTime has been added. It represents the time to establish connection.
By default it is not saved to CSV or XML, to have it saved add to user.properties:<br/>
<code>
jmeter.save.saveservice.connect_time=true
</code>
</p>
<figure width="1058" height="193" image="changes/2.13/connect_time_table.png"></figure>
<figure width="665" height="651" image="changes/2.13/connect_time_tree.png"></figure>
<ch_title>Aggregate Graph and Report</ch_title>
<p>The listeners Aggregate Graph and Aggregate Report previously showed only the 90 percentile (historical behavior), the 95 percentile and the 99 percentile have been added and are customizable.
To setup the percentiles value you want, add to user.properties:<br/>
<code>
aggregate_rpt_pct1=90<br/>
aggregate_rpt_pct2=95<br/>
aggregate_rpt_pct3=99
</code>
<figure width="801" height="681" image="changes/2.13/aggregate_graph_new_percentile.png"></figure>
</p>
<ch_title>HTTP(S) Test Script Recorder</ch_title>
<p>Now component is able to detect authentication schemes and automatically adds a pre-configured HTTP Authorization Manager with the correct Mechanism.
</p>
<ch_title>HTTP Request</ch_title>
<p>The CalDAV verbs (Calendar extensions to WebDAV) REPORT and MKCALENDAR have been added in the HTTP Request sampler.
<figure width="716" height="324" image="changes/2.13/new_methods_caldav.png"></figure>
</p>
<ch_title>JDBC Request</ch_title>
<p>The ResultSet can be get as a object, this allows to handle more easily the results after in BeanShell, JSR223 scripts, &hellip;
<figure width="683" height="628" image="changes/2.13/jdbc_resultset_handler.png"></figure>
</p>
<ch_title>Distributed Testing</ch_title>
<p>To allow better usage of Distributed Testing in the cloud, retry behaviour has been added when starting test on servers.
Read <a href="./usermanual/remote-test.html#retries" >this</a> for more details.
<figure width="669" height="202" image="changes/2.13/distributed_retry.png"></figure>
</p>
<ch_title>Distributed Testing performance</ch_title>
<p>Since JMeter 2.13, Stripping modes (StrippingBatch being the default mode) now also strip responses from SubResults improving consumed network bandwidth.
</p>
<ch_title>Documentation refresh</ch_title>
<p>A new style for website (responsive and more up to date) has been created by Felix Schumacher.
Documentations have been refreshed particularly:
<ul>
<li><a href="./usermanual/build-ws-test-plan.html">Building a Webservice Test Plan</a></li>
<li><a href="./usermanual/best-practices.html">Best Practices</a></li>
<li><a href="./usermanual/boss.html">Help! My boss wants me to load test our application!</a></li>
</ul>
</p>
<ch_category>GUI Improvements</ch_category>
<ch_title>Module Controller</ch_title>
<p>The Module Controller now shows the target controller in a tree view (instead of combo list).
<figure width="306" height="372" image="changes/2.13/module_controller_tree_view.png"></figure>
</p>
<ch_title>Toolbar</ch_title>
<p>JMeter's toolbar has been refreshed for some icons (start, toggle, etc.). Three sizes are now available for the icons: 22x22, 32x32 and 48x48.<br>
The property to define your preferred size is:
<pre>jmeter.toolbar.icons.size=value</pre>
with the value 22x22 (default size), 32x32 or 48x48.</br></p>
<p>The toolbar with 22x22 pixels icons

</p>
<p>The toolbar with 48x48 pixels icons
<figure width="716" height="143" image="changes/2.13/toolbar_48x48.png"></figure>
</p>
<ch_title>HTTP(S) Test Script Recorder</ch_title>
<p>If your Test Plan does not contains a Recording Controller, a new warning message will appear if the
HTTP(S) Test Script Recorder is configured to send the samples into a Recording Controller.
<figure width="858" height="386" image="changes/2.13/warning_message_proxy.png"></figure>

<!-- =================== Incompatible changes =================== -->
<ch_section>Incompatible changes</ch_section>
<ul>
<li>Since 2.13, Aggregate Graph, Summary Report and Aggregate Report now export percentages to %, before they exported the decimal value which differed from what was shown in GUI</li>
<li>Third party plugins may be impacted by fix of <bugzilla>57586</bugzilla>, ensure that your subclass of HttpTestSampleGui implements ItemListener if you relied on parent class doing so.</li>
<li>Report package has been removed, ApacheJMeter_report.jar is not generated anymore as a consequence, see <bugzilla>57269</bugzilla></li>

This error is related to increased security in Java 7 version u16 (MD2) and version u40 (Certificate size lower than 1024 bits), and Java 8 too.
<br></br>
To allow you to perform your HTTPS request, you can downgrade the security of your Java installation by editing
the Java <b>jdk.certpath.disabledAlgorithms</b> property. Remove the MD2 value or the constraint on size, depending on your case.
<br></br>
This property is in this file:
<pre>JAVA_HOME/jre/lib/security/java.security</pre>
See <bugzilla>56357</bugzilla> for details.

<ch_title>Java 8 support</ch_title>
<p>Now, JMeter 2.12 is compliant with Java 8.</p>
<ch_category>New Elements</ch_category>
<ch_title>Critical Section Controller</ch_title>
<p>The Critical Section Controller allow to serialize the execution of a section in your tree.
Only one instance of the section will be executed at the same time during the test.</p>
<figure width="683" height="240" image="changes/2.12/01_critical_section_controller.png"></figure>
<ch_title>DNS Cache Manager</ch_title>
<p>The new configuration element <b>DNS Cache Manager</b>(see <bugzilla>56841</bugzilla>) improves the testing of:
<ul>
<li>CDN (Content Delivery Network)</li>
<li>DNS load balancing.</li>
<li>Load Balancers like Amazon Elastic Load Balancer</li>
</ul>
</p>
<figure width="573" height="359" image="changes/2.12/02_dns_cache_manager.png"></figure>
<ch_category>Core Improvements</ch_category>
<ch_title>Smarter Recording of Http Test Plans</ch_title>
<p>Test Script Recorder has been improved in many ways</p>
<ul>
<li>Better matching of Variables in Requests, making Test Script Recorder variabilize your sampler during recording more versatile</li>
<li>Ability to filter from View Results Tree the Samples that are excluded from recording, this lets you concentrate on recorded Samplers analysis and not bother with useless Sample Results
<figure width="1094" height="647" image="changes/2.12/14_recorder_filter.png"></figure>
</li>
<li>Better defaults for recording, since this version Recorder will number created Samplers letting you find them much easily in View Results Tree.
Grouping of Samplers under Transaction Controller will be smarter making all requests emitted by a web page be children as new Transaction Controller</li>
</ul>
<ch_title>Support of Webdav requests</ch_title>
<p>You can now test against WebDav server using HttpClient4 Implementation of Http Request</p>
<figure width="989" height="406" image="changes/2.12/13_webdav.png"></figure>
<ch_title>Better handling of embedded resources</ch_title>
<p>When download embedded resources is checked, JMeter now uses User Agent header to download or not resources embedded within conditional comments as per <a href="http://msdn.microsoft.com/en-us/library/ms537512%28v=vs.85%29.aspx" target="_blank">About conditional comments</a>.</p>
<ch_title>Ability to customize Cache Manager (Browser cache simulation) handling of cached resources</ch_title>
<p>You can now configure the behaviour of JMeter when a resource is found in Cache, this can be controlled with <i>cache_manager.cached_resource_mode</i> property</p>
<figure width="1024" height="314" image="changes/2.12/12_cache_resource_mode.png"></figure>
<ch_title>JMS Publisher / JMS Point-to-Point</ch_title>
<p> Add JMSPriority and JMSExpiration fields for these samplers.</p>
<figure width="877" height="314" image="changes/2.12/04_jms_publisher.png"></figure>
<figure width="877" height="293" image="changes/2.12/05_jms_point_to_point.png"></figure>
<ch_title>Mail Reader Sampler</ch_title>
<p>You can now specify the number of messages that want you retrieve (before all messages were retrieved).
In addition, you can fetch only the message header now.</p>
<figure width="814" height="416" image="changes/2.12/03_mail_reader_sampler.png"></figure>
<ch_title>SMTP Sampler</ch_title>
<p>Adding the Connection timeout and the Read timeout to the <b>SMTP Sampler.</b></p>
<figure width="796" height="192" image="changes/2.12/06_smtp_sampler.png"></figure>
<ch_title>Synchronizing Timer </ch_title>
<p>Adding a timeout to define the maximum time to waiting of the group of virtual users.</p>
<figure width="546" height="144" image="changes/2.12/09_synchronizing_timer.png"></figure>
<ch_title>Performance improvements</ch_title>
<p>A big improvement in performances of Functions has been made by lifting useless synchronization. It concerns all functions except __StringFromFile, __XPath and __BeanShell, see <bugzilla>57114</bugzilla></p>
<p>__jexl2 performances have been improved to avoid contention point, see <bugzilla>56708</bugzilla></p>
<ch_category>GUI Improvements</ch_category>
<ch_title>Undo/Redo support</ch_title>
<p>Undo / Redo has been introduced and allows user to undo/redo changes made on Test Plan Tree. This feature (ALPHA MODE) is disabled by default, to enable it set property <b>undo.history.size=25</b> </p>
<figure width="1024" height="56" image="changes/2.12/10_undo_redo.png"></figure>
<ch_title>View Results Tree</ch_title>
<p>Improve the ergonomics of View Results Tree by changing placement of Renderers and allowing custom ordering
(with the property <i>view.results.tree.renderers_order</i>).</p>
<figure width="900" height="329" image="changes/2.12/07_view_results_tree.png"></figure>
<ch_title>Response Time Graph</ch_title>
<p>Adding the ability for the <b>Response Time Graph</b> listener to save/restore format its settings in/from the jmx file.</p>
<figure width="997" height="574" image="changes/2.12/08_response_time_graph.png"></figure>
<ch_title>Log Viewer</ch_title>
<p>Starting with this version, the last lines of JMeter's log file (jmeter.log) can be viewed directly in GUI by clicking on Warning icon in the upper right corner.
This will unfold the Log Viewer panel and show logs.</p>
<figure width="1024" height="437" image="changes/2.12/11_log_viewer.png"></figure>
<ch_title>File Opening</ch_title>
<p>Now, "Open File dialog" uses last opened file folder as start folder, see <bugzilla>52707</bugzilla></p>
<!-- =================== Known bugs =================== -->
<ch_section>Known bugs</ch_section>
<ul>
<li>The Once Only controller behaves correctly under a Thread Group or Loop Controller,
but otherwise its behaviour is not consistent (or clearly specified).</li>
<li>
The numbers that appear to the left of the green box are the number of active threads / total number of threads,
the total number of threads only applies to a locally run test, otherwise it will show 0 (see <bugzilla>55510</bugzilla>).
</li>
<li>
Note that there is a <a href="http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6396599 ">bug in Java</a>
on some Linux systems that manifests itself as the following error when running the test cases or JMeter itself:
<pre>
[java] WARNING: Couldn't flush user prefs:
java.util.prefs.BackingStoreException:
java.lang.IllegalArgumentException: Not supported: indent-number
</pre>
This does not affect JMeter operation. This issue is fixed since Java 7b05.
</li>
<li>
Note that under some windows systems you may have this WARNING:
<pre>
java.util.prefs.WindowsPreferences
WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0
x80000002. Windows RegCreateKeyEx(&hellip;) returned error code 5.
</pre>
The fix is to run JMeter as Administrator, it will create the registry key for you, then you can restart JMeter as a normal user and you won't have the warning anymore.
</li>
<li>
With Java 1.6 and Gnome 3 on Linux systems, the JMeter menu may not work correctly (shift between mouse's click and the menu).
This is a known Java bug (see <bugzilla>54477 </bugzilla>).
A workaround is to use a Java 7 runtime (OpenJDK or Oracle JDK).
</li>
<li>
With Oracle Java 7 and Mac Book Pro Retina Display, the JMeter GUI may look blurry.
This is a known Java bug, see Bug <a href="http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8000629" >JDK-8000629</a>.
A workaround is to use a Java 7 update 40 runtime which fixes this issue.
</li>
<li>
You may encounter the following error: <i>java.security.cert.CertificateException: Certificates does not conform to algorithm constraints</i>
if you run a HTTPS request on a web site with a SSL certificate (itself or one of SSL certificates in its chain of trust) with a signature
algorithm using MD2 (like md2WithRSAEncryption) or with a SSL certificate with a size lower than 1024 bits.
This error is related to increased security in Java 7 version u16 (MD2) and version u40 (Certificate size lower than 1024 bits), and Java 8 too.
<br></br>
To allow you to perform your HTTPS request, you can downgrade the security of your Java installation by editing
the Java <b>jdk.certpath.disabledAlgorithms</b> property. Remove the MD2 value or the constraint on size, depending on your case.
<br></br>
This property is in this file:
<pre>JAVA_HOME/jre/lib/security/java.security</pre>
See <bugzilla>56357</bugzilla> for details.
</li>
</ul>
<!-- =================== Incompatible changes =================== -->
<ch_section>Incompatible changes</ch_section>
<ul>
<li>Since JMeter 2.12, active threads in all thread groups and active threads in current thread group are saved by default to CSV or XML results, see <bugzilla>57025</bugzilla>.
This is usually the expected behaviour as you want to have the number of running threads during the test. But if you want to revert to previous behaviour, set property <b>jmeter.save.saveservice.thread_counts=false</b></li>
<li>Since JMeter 2.12, Mail Reader Sampler will show 1 for number of samples instead of number of messages retrieved, see <bugzilla>56539</bugzilla></li>
<li>Since JMeter 2.12, when using Cache Manager, if resource is found in cache no SampleResult will be created, in previous version a SampleResult with empty content and 204 return code was returned, see <bugzilla>54778</bugzilla>.
You can choose between different ways to handle this case, see cache_manager.cached_resource_mode in jmeter.properties.</li>
<li>Since JMeter 2.12, Log Viewer will no more clear logs when closed and will have logs available even if closed. See <bugzilla>56920</bugzilla>. Read <a href="./usermanual/hints_and_tips.html#debug_logging">Hints and Tips &gt; Enabling Debug logging</a>
for details on configuring this component.</li>

<ch_title>HTTP(S) Test Script Recorder improvements</ch_title>
<p>
Following improvements have been made since major changes introduced in JMeter 2.10 on HTTP(S) Test Script Recorder:
<ul>
<li>Better detection of missing or invalid configuration of keytool utility</li>
<li>New system property keytool.directory (see system.properties) lets you configure directory containing keytool in case on non-standard installation</li>
</ul>
</p>
<ch_title>JMS Publisher/Point to Point : Add ability to set typed values in JMS header properties</ch_title>
<p>In the samplers JMS Publisher and JMS Point-to-Point, you can now set up the class of values for the JMS header properties. Previously only String was possible.</p>
<p>
<figure width="928" height="796" image="changes/2.11/01_jms_properties_typed_values.png"></figure>
</p>
<ch_title>View Results Tree : Add an XPath Tester </ch_title>
<p>In View Results Tree listener, a new XPath tester can be used to test XPATH expressions.</p>
<p>
<figure width="990" height="765" image="changes/2.11/03_xpath_tester.png"></figure>
</p>
<ch_title>Ability to choose the client alias for the cert key in JsseSslManager such that Mutual SSL auth testing can be made more flexible</ch_title>
<p>When testing client based certificate authentications you have now better control on certificate you use through a new field "Variable name holding certificate alias", this
field lets you select the certificate you want to send to server to authenticate. You can use a CSV Data Set as a holder for the variable value.</p>
<p>
<figure width="471" height="189" image="changes/2.11/07_keystore_config.png"></figure>
</p>
<ch_title>Add a "Save as Test Fragment" option </ch_title>
<p>In the file menu, a new option allow to save a group of elements as a Test fragment.</p>
<p>
<figure width="295" height="242" image="changes/2.11/05_save_as_fragement.png"></figure>
</p>
<ch_title>Summariser is be enabled by default in Non GUI mode</ch_title>
<p>When you run JMeter from command line, now JMeter displays some statistics from the Summariser mode.</p>
<p>
<figure width="1287" height="386" image="changes/2.11/06_summariser.png"></figure>
</p>
<ch_title>Transaction Controller:Change default property "Include duration of timer&hellip;" for newly created element</ch_title>
<p>Starting from 2.11, Transaction Controller is configured by default to exclude processing time of pre/post processors as long as timers pause.</p>

<!-- =================== Known bugs =================== -->
<ch_section>Known bugs</ch_section>
<ul>
<li>The Once Only controller behaves correctly under a Thread Group or Loop Controller,
but otherwise its behaviour is not consistent (or clearly specified).</li>
<li>Listeners don't show iteration counts when a If Controller has a condition which is always false from the first iteration (see <bugzilla>52496</bugzilla>).
A workaround is to add a sampler at the same level as (or superior to) the If Controller.
For example a Test Action sampler with 0 wait time (which doesn't generate a sample),
or a Debug Sampler with all fields set to False (to reduce the sample size).
</li>
<li>
The numbers that appear to the left of the green box are the number of active threads / total number of threads,
the total number of threads only applies to a locally run test, otherwise it will show 0 (see <bugzilla>55510</bugzilla>).
</li>
<li>
Note that there is a <a href="http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6396599 ">bug in Java</a>
on some Linux systems that manifests itself as the following error when running the test cases or JMeter itself:
<pre>
[java] WARNING: Couldn't flush user prefs:
java.util.prefs.BackingStoreException:
java.lang.IllegalArgumentException: Not supported: indent-number
</pre>
This does not affect JMeter operation. This issue is fixed since Java 7b05.
</li>
<li>
With Java 1.6 and Gnome 3 on Linux systems, the JMeter menu may not work correctly (shift between mouse's click and the menu).
This is a known Java bug (see <bugzilla>54477 </bugzilla>).
A workaround is to use a Java 7 runtime (OpenJDK or Oracle JDK).
</li>
<li>
With Oracle Java 7 and Mac Book Pro Retina Display, the JMeter GUI may look blurry.
This is a known Java bug, see Bug <a href="http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8000629" >JDK-8000629</a>.
A workaround is to use a Java 7 update 40 runtime which fixes this issue.
</li>
</ul>
<!-- =================== Incompatible changes =================== -->
<ch_section>Incompatible changes</ch_section>
<ul>
<li>When creating a new Transaction Controller, property "Include duration of timer and pre-post processors in generated sample" will be unchecked starting from version 2.11</li>
<li>In Non GUI mode, since 2.11 summariser is enabled with a 30 seconds frequency</li>
<li>JMeter is more lenient with redirect handling and relaxes on RFC2616 by allowing relative locations. See property "jmeter.httpclient.strict_rfc2616" in jmeter.properties to change this behaviour, see <bugzilla>55717</bugzilla></li>
<li>When creating a new Response Assertion, property "Pattern Matching Rules" now defaults to Substring starting from version 2.11</li>

The numbers that appear to the left of the green box are the number of active threads / total number of threads,

<!-- =================== Incompatible changes =================== -->
<ch_section>Incompatible changes</ch_section>
<ul>
<li><b>SMTP Sampler</b> now uses eml file subject if subject field is empty</li>
<li>With this version autoFlush has been turned off on PrintWriter in charge of writing test results.
This results in improved throughput for intensive tests but can result in more test data loss in case
of JMeter crash (extremely rare). To revert to previous behaviour set <code>jmeter.save.saveservice.autoflush</code> property to <code>true</code>.</li>
<li>
Shortcut for <b>Function Helper Dialog</b> is now <i>CTRL+SHIFT+F1 (CMD + SHIFT + F1 for Mac OS)</i>.
The original key sequence <i>(Ctrl+F1)</i> did not work in some locations (it is consumed by the Java Swing ToolTipManager).
It was therefore necessary to change the shortcut.
</li>
<li>
<b>Webservice (SOAP) Request</b> has been removed by default from GUI as Element is deprecated. (Use <b>HTTP Request</b>
with <i>Body Data</i>, see also the Template <i>Building a SOAP Webservice Test Plan</i>), if you need to show it, see property <code>not_in_menu</code> in <i>jmeter.properties</i>
</li>
<li>
<b>Transaction Controller</b> now sets <i>Response Code</i> of <i>Generated Parent Sampler</i>
(if <i>Generated Parent Sampler</i> is checked) to response code of first failing child in case of failure of one of the children, in previous versions <i>Response Code</i> was empty.
</li>
<li>
In previous versions, <b>IncludeController</b> could run Test Elements located inside a <b>Thread Group</b>, this behaviour (<i>which was not documented</i>)
could result in weird behaviour, it has been removed in this version (see <bugzilla>55464</bugzilla>).
The correct way to include Test Elements is to use <b>Test Fragment</b> as stated in documentation of <b>Include Controller</b>.
</li>
<li>
The retry count for the HttpClient 3.1 and HttpClient 4.x samplers has been changed to <b>0</b>.
Previously the default was 1, which could cause unexpected additional traffic.
</li>
<li>Starting with this version, the <b>HTTP(S) Test Script Recorder</b> tries to detect when a sample is the result of a previous
redirect. If the current response is a redirect, JMeter will save the redirect URL. When the next request is received,
it is compared with the saved redirect URL and if there is a match, JMeter will disable the generated sample.
To revert to previous behaviour, set the property <code>proxy.redirect.disabling=false</code>
</li>
<li>Starting with this version, in <b>HTTP(S) Test Script Recorder</b> if Grouping is set to <i>Put each group in a new Transaction Controller</i>,
the Recorder will create <b>Transaction Controller</b> instances with <i>Include duration of timer and pre-post processors in generated sample</i> set
to false. This default value reflect more accurately response time.
</li>
<li><code>__escapeOroRegexpChars</code> function (which escapes ORO reserved characters) no longer trims the value (see <bugzilla>55328</bugzilla>)
</li>
<li>The <i>commons-lang-2.6.jar</i> has been removed from embedded libraries in <code>jmeter/lib</code> folder as it is not needed by JMeter at run-time
(it is only used by Apache Velocity for generating documentation).
If you use any plugin or third-party code that depends on it, you need to add it in <code>jmeter/lib</code> folder

<!-- =================== 2.9 =================== -->
<h1>Version 2.9</h1>
<h2>New and Noteworthy</h2>
<h3><u>Core Improvements:</u></h3>
<h4>* A new Extractor that uses CSS or jquery-like selector syntax has been introduced,
it allows using either JODD or JSOUP implementations</h4>
<p>
<figure width="762" height="277" image="changes/2.9/01_css_jquery_extractor.png"></figure>
</p>
<p>Result: the title of the page in a JMeter variable
<figure width="719" height="171" image="changes/2.9/01_css_jquery_extractor_resul.png"></figure>
</p>
<h4>* JMeter can now handle different types of documents (PDF, MsOffice files, Apache OpenOffice's files, &hellip;)
within different elements </h4>
<ul>
<li>Regular Expression Extractor, extract text from documents</li>
<li>Assertion Response, check text in documents</li>
<li>View Results Tree, view as a text the documents</li>
</ul>
<p>
<figure width="761" height="345" image="changes/2.9/02_document_render_view_results_tree.png"></figure>
</p>
<h4>* A new Regex User Parameters Pre-Processor that enables injecting input parameter names and values
using a reference extracted by Regular Expression Extractor from a previous response</h4>
<p>
<figure width="727" height="138" image="changes/2.9/13_regex_user_params.png"></figure>
</p>
<h4>* TCP Sampler: new options</h4>
<p>TCP Sampler has been enhanced with new options to allow setting <b>Close Connection</b>,
<b>SO_LINGER</b> and <b>End of line(EOL) byte value</b>
<figure width="1147" height="302" image="changes/2.9/03_new_options_tcp_sampler.png"></figure>
</p>
<h4>* A new function <i>__escapeOroRegexpChars(,)</i> has been introduced quote ORO regexp meta characters</h4>
<h4>* ForEach Controller: new fields</h4>
<p>ForEach Controller has now 2 new fields to control start and end of loop
<figure width="320" height="203" image="changes/2.9/04_for_each_new_fields.png"></figure>
</p>
<h4>* Result Status Action Handler now has a new option to "Start next thread loop"</h4>
<p>
<figure width="722" height="132" image="changes/2.9/05_result_status_action_handler.png"></figure>
</p>
<h4>* JMS Publisher: new option</h4>
<p>JMS Publisher can now send Bytes Messages</p>
<figure width="833" height="701" image="changes/2.9/11_jms_publisher_bytes.png"></figure>
<h4>* Memory and performance improvements</h4>
<p>Significant improvements have been done in this version on memory usage per Thread and CPU when more
than one Post Processor is used as child of a Sampler</p>
<p>JSR223 Elements (enable using Groovy, Scala, &hellip; as scripting languages) have been improved to enable caching
of Compilation results when scripts are passed in Text area</p>
<figure width="841" height="470" image="changes/2.9/12_jsr223_sampler.png"></figure>
<p>Some configuration defaults have changed to improve performances by default(see <bugzilla>54412</bugzilla>),
see description in New and Noteworthy section.
<ul>
<li>Distributed testing now uses MODE_STRIPPED_BATCH, which returns samples in batch mode (every 100 samples
or every minute by default). Note also that MODE_STRIPPED_BATCH strips response data from SampleResult,
so if you need it change to another mode (mode property in jmeter.properties)</li>
<li>Result data are now saved to CSV by default (jmeter.save.saveservice.output_format in jmeter.properties)</li>
</ul>
</p>
<h4>* XPath Assertion now enables using a JMeter variable as input</h4>
<p>
<figure width="800" height="317" image="changes/2.9/14_xpath_assertion.png"></figure>
</p>
<h3><u>GUI and ergonomy Improvements:</u></h3>
<h4>* Search feature has been improved to search within more internal fields of elements and expand search results</h4>
<h4>* Copy/paste is now possible between 2 JMeter instances &gt;= 2.9 version</h4>
<p>Copy element(s) from one JMeter instance:
<figure width="618" height="262" image="changes/2.9/06_copy_paste_between_2_jmeter1.png"></figure>
</p>
<p>Paste element(s) into a second JMeter instance:
<figure width="617" height="278" image="changes/2.9/06_copy_paste_between_2_jmeter2.png"></figure>
</p>
<h4>* HTTP Header Manager</h4>
<p>Allow copy from clipboard to HeaderPanel, headers are supposed to be separated by new line
and have the following form <i>name:value</i>
<figure width="661" height="263" image="changes/2.9/07_header_panel_add_from_clipboard.png"></figure>
</p>
<h4>* Module Controller</h4>
<p>Module Controller has been improved to better render referenced controller and expand it by clicking on a new button
<figure width="832" height="274" image="changes/2.9/08_module_controller_improvements.png"></figure>
</p>
<h4>* HTTP Proxy Server</h4>
<p>HTTP Proxy Server now has a button to add a set of default exclusions for URL patterns,
this list can be configured through property : <i>proxy.excludes.suggested</i>
<figure width="811" height="214" image="changes/2.9/09_proxy_excludes_suggested.png"></figure>
</p>
<h4>* Rendering of target controller has been improved in HTTP Proxy Server</h4>
<h3><u>HTTP Proxy Server recording:</u></h3>
<p>* HTTP Proxy Server now automatically uses HTTP Request with Raw Post Body mode for
samples that only have one unnamed argument (JSON, XML, GWT, &hellip;)</p>
<p>* HTTP Proxy Server does not force user to select the type of Sampler in HTTP Sampler Settings,
this allows easier switch between implementations as Sampler do not have this information set anymore</p>
<p>
<figure width="484" height="307" image="changes/2.9/10_http_proxy_dont_force_http_type.png"></figure>
</p>
<p>* SamplerCreator interface has been enriched to meet new requirements for plug-in providers</p>
<p>* It is now possible to create binary sampler for x-www-form-urlencoded POST request by
modifying <i>proxy.binary.types</i> property to add application/x-www-form-urlencoded </p>
<p>* Improved timestamp format auto-detection when reading CSV files</p>
<!-- =================== Known bugs =================== -->
<h2>Known bugs</h2>
<p>The Once Only controller behaves correctly under a Thread Group or Loop Controller,
but otherwise its behaviour is not consistent (or clearly specified).</p>
<p>Listeners don't show iteration counts when a If Controller has a condition which is always false from the first iteration (see <bugzilla>52496</bugzilla>).
A workaround is to add a sampler at the same level as (or superior to) the If Controller.
For example a Test Action sampler with 0 wait time (which doesn't generate a sample),
or a Debug Sampler with all fields set to False (to reduce the sample size).
</p>
<p>Webservice sampler does not consider the HTTP response status to compute the status of a response, thus a response 500 containing a non empty body will be considered as successful, see <bugzilla>54006</bugzilla>.
To workaround this issue, ensure you always read the response and add a Response Assertion checking text inside the response.
</p>

Changing language can break part of the configuration of the following elements (see <bugzilla>53679</bugzilla>):
<ul>
<li>CSV Data Set Config (sharing mode will be lost)</li>
<li>Constant Throughput Timer (Calculate throughput based on will be lost)</li>
</ul>
</p>
<p>
The numbers that appear to the left of the green box are the number of active threads / total number of threads,
these only apply to a locally run test; they do not include any threads started on remote systems when using client-server mode, (see <bugzilla>54152</bugzilla>).
</p>
<p>
Note that there is a bug in Java on some Linux systems that manifests
itself as the following error when running the test cases or JMeter itself:
<pre>
[java] WARNING: Couldn't flush user prefs:
java.util.prefs.BackingStoreException:
java.lang.IllegalArgumentException: Not supported: indent-number
</pre>
This does not affect JMeter operation.
</p>
<!-- =================== Incompatible changes =================== -->
<h2>Incompatible changes</h2>
<p><b>JMeter requires now a Java 6 runtime or higher.</b></p>
<p>Some configuration defaults have changed to improve performances by default (see <bugzilla>54412</bugzilla>),
see description in New and Noteworthy section.</p>
<p>Webservice sampler now adds to request the headers that are set through Header Manager, these were previously ignored</p>
<p><i>jdbcsampler.cachesize</i> property has been removed, it previously limited the size of a per connection cache of Map &lt; String,
PreparedStatement &gt; , it also limited the size of this
map which held the PreparedStatement for SQL queries. This limitation provoked a bug <bugzilla>53995</bugzilla>.
It has been removed so now size of these 2 maps is not limited anymore. This change changes behaviour as starting from
this version no PreparedStatement will be closed during the test.</p>
<p>Starting with this version, there are some important changes on JSR223 Test Elements:
<ul>
<li>JSR223 Test Elements that have an invalid filename (not existing or unreadable) will make test fail instead of
making the element silently work</li>
<li>In JSR223 Test Elements: responseCodeOk, responseMessageOK and successful are set before
script is executed, if responseData is set it will not be overriden anymore by a toString() on script return value</li>
</ul>
</p>
<p>View Results Tree now considers response with missing content type as text.</p>
<p>In remote Test mode, JMeter now exits in error if one of the remote engines cannot be configured,
previously it started the test with available engines.</p>

<!-- =================== 2.8 =================== -->
<h1>Version 2.8</h1>
<h2>New and Noteworthy</h2>
<h3>Core Improvements:</h3>
<h4>Thread Group: New Option <i>Delay thread creation until needed</i></h4>
<p>New Option "Delay thread creation until needed" that will create and start threads when needed instead of creating them on Test startup<br></br>
<b>This new feature allows running tests with a huge number of short lived threads.</b>
<figure width="817" height="296" image="changes/2.8/12_delay_thread_creation.png"></figure>
</p>
<h4>HTTP Cookie Manager (IPv6 support)</h4>
<p>Add HTTPClient 4 cookie implementation in JMeter. <br/>
Cookie Manager has now the default HC3.1 implementation and a new choice HC4 implementation (compliant with IPv6 address)
<figure width="635" height="239" image="changes/2.8/11_hc4_cookie.png"></figure>
</p>
<h4>Memory and performance improvements</h4>
<p>Significant improvements have been done in this version on memory usage of JMeterThread</p>
<p>JSR223 Elements (enable using Groovy, scala, &hellip; as scripting languages) have been improved to enable:
<ul>
<li>usage of Compilable interface when available to boost CPU usage</li>
<li>caching of Compilation when scripts are used as Files</li>
</ul>
See <a href="http://wiki.apache.org/jmeter/JMeterPerformance">JMeter Performances across versions</a>
</p>
<h4>OS Process Sampler</h4>
<p>Allow defining files for stdout/stderr/stdin.
<figure width="820" height="531" image="changes/2.8/06_os_sampler_stdout-err-in.png"></figure>
</p>
<h4>HTTP Request: PATCH verb</h4>
<p>Add PATCH verb to HTTP sampler
<figure width="615" height="340" image="changes/2.8/01_http_patch_verb.png"></figure>
</p>
<h4>HTTP Request: HTTPClient 4 is now the default implementation</h4>
<p>HTTPClient 4 is now the default HTTP Request implementation (and for Proxy element when generating HTTP requests).<br/>
Previously the default was the HTTP Java implementation (i.e. the implementation provided by the JVM)
<figure width="558" height="288" image="changes/2.8/02_http_default_hc4.png"></figure>
</p>
<h4>HTTP Request</h4>
<p>Add Embedded URL Filter to HTTP Request Defaults Control (it was already present for HTTP Requests)
<figure width="586" height="682" image="changes/2.8/05_http_defaults_url_filter.png"></figure>
</p>
<h4>Miscellanous</h4>
<ul>
<li>CSV Dataset : Embedded new lines are now supported in quoted data</li>
<li>JMX files now contain the version of JMeter that created the file</li>
<li>JMeter Version is now available as property "jmeter.version"</li>
</ul>
<h3>Reporting Improvements:</h3>
<h4>Response Time Graph</h4>
<p>Add a new visualizer Response Time Graph to draw a line graph showing the evolution of response time for a test
<figure width="993" height="549" image="changes/2.8/09_resp_time_graph.png"></figure>
</p>
<p>Settings for Response Time Graph
<figure width="989" height="602" image="changes/2.8/08_resp_time_graph_settings.png"></figure>
</p>
<h4>View Results in Table</h4>
<p>Add latency to View Result in Table listener
<figure width="998" height="324" image="changes/2.8/10_latency_view_results_table.png"></figure>
</p>
<h4>Aggregate Graph</h4>
<p>Small improvements: legend at left or right is now on 1 column (instead of 1 large line), &hellip;
<figure width="989" height="418" image="changes/2.8/07_aggregate_graph_legend_left_right.png"></figure>
</p>
<h3>GUI and ergonomy Improvements:</h3>
<h4>HTTP Proxy Server simplifications</h4>
<p>HTTPS Spoofing options have been removed from Proxy as HTTPS recording is directly available since JMeter 2.4.
<figure width="940" height="277" image="changes/2.8/03_remove_https_spoofing1.png"></figure>
</p>
<h4>HTTP Proxy Server</h4>
<p>Allow URL Filters to be pasted from clipboard
<figure width="707" height="614" image="changes/2.8/15_add_from_clipboard_filter.png"></figure>
</p>
<h4>Find in JMeter</h4>
<p>CTRL + F for the new Find feature
<figure width="477" height="157" image="changes/2.8/14_ctrl_F_shortcut.png"></figure>
ESC key now closes popups.
</p>
<h4>User Interface in GNOME 3</h4>
<p>Display 'Apache JMeter' title in app title bar in Gnome 3
<figure width="441" height="253" image="changes/2.8/13_gnome3_title.png"></figure>
</p>
<!-- =================== Known bugs =================== -->
<h2>Known bugs</h2>
<p>The Once Only controller behaves correctly under a Thread Group or Loop Controller,
but otherwise its behaviour is not consistent (or clearly specified).</p>
<p>Listeners don't show iteration counts when a If Controller has a condition which is always false from the first iteration (see <bugzilla>52496</bugzilla>).
A workaround is to add a sampler at the same level as (or superior to) the If Controller.
For example a Test Action sampler with 0 wait time (which doesn't generate a sample),
or a Debug Sampler with all fields set to False (to reduce the sample size).
</p>
<p>
Changing language can break part of the configuration of the following elements (see <bugzilla>53679</bugzilla>):
<ul>
<li>CSV Data Set Config (sharing mode will be lost)</li>
<li>Constant Throughput Timer (Calculate throughput based on will be lost)</li>
</ul>
</p>
<p>
Note that there is a bug in Java on some Linux systems that manifests
itself as the following error when running the test cases or JMeter itself:
<pre>
[java] WARNING: Couldn't flush user prefs:
java.util.prefs.BackingStoreException:
java.lang.IllegalArgumentException: Not supported: indent-number
</pre>
This does not affect JMeter operation.
</p>
<!-- =================== Incompatible changes =================== -->
<h2>Incompatible changes</h2>
<p>
When using CacheManager, JMeter now caches responses for GET queries provided header Cache-Control is different from "no-cache" as described in specification.
Furthermore it doesn't put anymore in Cache deprecated entries for "no-cache" responses. See <bugzilla>53521</bugzilla> and <bugzilla>53522</bugzilla>
</p>
<p>
A major change has occurred on JSR223 Test Elements, previously variables set up before script execution where stored in ScriptEngineManager which was created once per execution,
now ScriptEngineManager is a singleton shared by all JSR223 elements and only ScriptEngine is created once per execution, variables set up before script execution are now stored
in Bindings created on each execution, see <bugzilla>53365</bugzilla>.
</p>
<p>
JSR223 Test Elements using Script file are now Compiled if ScriptEngine supports this feature, see <bugzilla>53520</bugzilla>.
</p>
<p>
Shortcut for Function Helper Dialog is now CTRL+F1 (CMD + F1 for Mac OS), CTRL+F (CMD+F1 for Mac OS) now opens Search Dialog.
</p>
<p>
By default, the TestCompiler now stores details of which pairs it has seen in Controller instances rather than in a static Set.
[<bugzilla>53796</bugzilla>]
This gives much better memory behaviour for delayed start test plans, as memory used is proportional to the number of concurrent threads.
With the static Set memory usage was proportional to the total thread count.
This change is very unlikely to cause a problem.
The original behaviour can be restored by setting the property <code>TestCompiler.useStaticSet=true</code>
</p>
<p>
HTTPS Spoofing options have been removed from Proxy as HTTPS recording is directly available since JMeter 2.4.

<!-- =================== Known bugs =================== -->
<h2>Known bugs</h2>
<p>The Once Only controller behaves correctly under a Thread Group or Loop Controller,
but otherwise its behaviour is not consistent (or clearly specified).</p>
<p>Listeners don't show iteration counts when a If Controller has a condition which is always false from the first iteration (see <bugzilla>52496</bugzilla>).
A workaround is to add a sampler at the same level as (or superior to) the If Controller.
For example a Test Action sampler with 0 wait time (which doesn't generate a sample),
or a Debug Sampler with all fields set to False (to reduce the sample size).
</p>
<!-- =================== Incompatible changes =================== -->
<h2>Incompatible changes</h2>
<p>
When doing replacement of User Defined Variables, Proxy will not substitute partial values anymore when "Regexp matching" is used. It will use Perl 5 word matching ("\b")
</p>
<p>
In User Defined Variables, Test Plan, HTTP Sampler Arguments Table, Java Request Defaults, JMS Sampler and Publisher, LDAP Request Defaults and LDAP Extended Request Defaults, rows with
empty Name and Value are no more saved.
</p>
<p>
JMeter now expands the Test Plan tree to the testplan level and no further and selects the root of the tree. Furthermore default value of onload.expandtree is false.
</p>
<p>
Graph Full Results Listener has been removed.
</p>
<p>
When calling "Clear All" command, if Log Viewer is displayed its content will be cleared.

</p>
<h3>JMeter jars available from Maven repository</h3>
<p>
JMeter jars are now available from Maven repository.
</p>
<!-- =================== Known bugs =================== -->
<h2>Known bugs</h2>
<p>
The Include Controller has some problems in non-GUI mode (see Bugs 40671, 41286, 44973, 50898).
In particular, it can cause a NullPointerException if there are two include controllers with the same name.
</p>
<p>The Once Only controller behaves correctly under a Thread Group or Loop Controller,
but otherwise its behaviour is not consistent (or clearly specified).</p>
<p>Listeners don't show iteration counts when a If Controller has a condition which is always false from the first iteration (see <bugzilla>52496</bugzilla>).
A workaround is to add a sampler at the same level as (or superior to) the If Controller.
For example a Test Action sampler with 0 wait time (which doesn't generate a sample),
or a Debug Sampler with all fields set to False (to reduce the sample size).
</p>
<!-- =================== Incompatible changes =================== -->
<h2>Incompatible changes</h2>
<p>
JMeter versions since 2.1 failed to create a container sample when loading embedded resources.
This has been corrected; can still revert to the <bugzilla>51939</bugzilla> behaviour by setting the following property:
<code>httpsampler.separate.container=false</code>
</p>
<p>
Mirror server now uses default port 8081, was 8080 before 2.5.1.
</p>
<p>
TCP Sampler handles SocketTimeoutException, SocketException and InterruptedIOException differently since 2.6, when
these occurs, Sampler is marked as failed.
</p>
<p>
Sample Sender implementations now resolve their configuration on Client side since 2.6.
This behaviour can be changed with property sample_sender_client_configured (set it to false).
</p>
<p>
The HTTP User Parameter Modifier test element has been removed; it has been deprecated for a long time.

</ul>
<!-- ========== 2.5.1 =========== -->
<h1>Version 2.5.1</h1>
<h2>Summary of main changes</h2>
<ul>
<li>HttpClient4 sampler now re-uses connections properly (previously it would use one per sample, which could quickly cause resource exhaustion).</li>
<li>Various fixes to JMS samplers</li>
<li>Functions are no longer spuriously invoked when used with a Configuration element</li>
<li>WebService sampler GUI has been re-organized for better design and more user-friendliness. Some improments on WSDL configuration assistant</li>
<li>Better handling of test shutdown. System.exit now only called if there is no other option; even this can be disabled.</li>
</ul>
<h2>Known bugs</h2>
<p>
The Include Controller has some problems in non-GUI mode.
In particular, it can cause a NullPointerException if there are two include controllers with the same name.
</p>
<p>The Once Only controller behaves correctly under a Thread Group or Loop Controller,
but otherwise its behaviour is not consistent (or clearly specified).</p>
<p>The If Controller may cause an infinite loop if the condition is always false from the first iteration.
A workaround is to add a sampler at the same level as (or superior to) the If Controller.
For example a Test Action sampler with 0 wait time (which doesn't generate a sample),
or a Debug Sampler with all fields set to False (to reduce the sample size).
</p>
<p>
The menu item Options / Choose Language does not change all the displayed text to the new language.
[The behaviour has improved, but language change is still not fully working]
To override the default local language fully, set the JMeter property "language" before starting JMeter.
</p>
<h2>Incompatible changes</h2>
<p>
The HttpClient4 and Commons HttpClient 3.1 samplers previously used a retry count of 3.
This has been changed to default to 1, to be compatible with the Java implementation.
The retry count can be overridden by setting the relevant JMeter property, for example:
<pre>
httpclient4.retrycount=3
httpclient3.retrycount=3
</pre>
</p>
<h2>Bug fixes</h2>

<h2>Known bugs</h2>
<p>

<h2>Incompatible changes</h2>
<p>
Unsupported methods are no longer converted to GET by the Commons HttpClient sampler.
</p>
<p>
Removed method public static long currentTimeInMs().
This has been replaced by the instance method public long currentTimeInMillis().

<p>
ProxyControl.getSamplerTypeName() now returns a String rather than an int.
This is internal to the workings of the JMeter Proxy &amp; its GUI, so should not affect any user code.

<li>Many other improvements have been made, please see below and in the manual.</li>
</ul>
</p>
<!-- ========================= End of summary ===================================== -->
<h2>Known bugs</h2>
<p>
The Include Controller has some problems in non-GUI mode.
In particular, it can cause a NullPointerException if there are two include controllers with the same name.
</p>
<p>Once Only controller behaves correctly under a Thread Group or Loop Controller,
but otherwise its behaviour is not consistent (or clearly specified).</p>
<p>
The menu item Options / Choose Language does not change all the displayed text to the new language.
[The behaviour has improved, but language change is still not fully working]
To override the default local language fully, set the JMeter property "language" before starting JMeter.
</p>
<h2>Incompatible changes</h2>
<p>
HTTP Redirect now defaults to "Follow Redirects" rather than "Redirect Automatically".
This is to enable JMeter to track cookies that may be sent during redirects.
This does not affect existing test plans; it only affects the default for new HTTP Samplers.
</p>
<p>
The Avalon file format for JMX and JTL files is no longer supported.
Any such files will need to be converted by reading them in JMeter 2.3.4 and resaving them.
</p>
<p>
The XPath Assertion and XPath Extractor elements no longer fetch external DTDs by default; this can be changed in the GUI.
</p>
<p>
JMSConfigGui has been renamed as JMSSamplerGui.
This does not affect existing test plans.
</p>
<p>
The constructor public SampleResult(SampleResult res) has been changed to become a true "copy constructor".
It no longer calls addSubResult(). This may possibly affect some 3rd party add-ons.
</p>

</ul>
<!-- =================== -->
<h1>Version 2.3.3</h1>
<h2>Summary of main changes</h2>
<p>
The handling of test closedown is much improved.
The gradual "Shutdown" command now waits until all threads have stopped,
and does not report an error if threads don't stop within 5 seconds.
The immediate "Stop" command can now be used if "Shutdown" takes too long.
Also the immediate "Stop" command is able to interrupt samplers which support the new Interruptible interface (e.g. HTTP and SOAP, FTP).
This allows immediate completion of pending responses.
Non-GUI mode tests can also now be sent a "Shutdown" or "Stop" message.
<complink name="Test Action"/> now supports a "Stop Now" action,
as do the <complink name="Thread Group"/> and <complink name="Result Status Action Handler"/> Post Processor elements.
</p>
<p>
HTTP Cookie handling is improved, and HTTP POST can now use variable file names correctly.
HTTP, SOAP/XML-RPC and WebService(SOAP) sampler character encodings updated to be more consistent.
HTTP Samplers now support connection and response timeouts (requires JVM 1.5 for the HTTP Java sampler).
Together with the closedown improvements described above, this should avoid most cases where a test run hangs.
Multiple Header Manager elements are now supported for a single HTTP sampler.
The Proxy Server is improved, and no longer stores "Host" headers by default.
</p>
<p>
JDBC Request can optionally save the results of Select statements to variables.
JDBC Request now handles quoted strings and UTF-8, and can handle arbitrary variable types.
</p>
<p>
There are several new <a href="usermanual/functions.html">functions</a>:
__char() function: allows arbitrary Unicode characters to be entered in fields.
__unescape() function: allows Java-escaped strings to be used.
_unescapeHtml() function: decodes Html-encoded text.
__escapeHtml() function: encodes text using Html-encoding.
A reference to a missing function - e.g. ${__missing(a)} - is now treated the same as a missing variable.
Previously the function name - and leading { - were dropped. This makes it easier to debug test plans.
</p>
<p>
Some Assertions can now be applied to sub-samples as well as (or instead of) just the parent sample.
There is a new <complink name="Random Variable"/> Configuration element.
</p>
<p>
JMS samplers are much improved (see details below). The <complink name="TCP Sampler"/> now supports some additional clients and is a bit more flexible.
</p>
<p>
Client-server mode has been improved, and the server can optionally use a fixed RMI port, which should help with setting up firewalls.
</p>
<p>
Various I18N changes have been made; language change works better (though not perfect yet).
There are improved French translations as well as new Polish and Brazilian Portugese translations.
</p>
<p>
The BeanShell jar is now included with the binary archive; there is no need to download it separately.
</p>
<!-- ========================= End of summary ===================================== -->
<h2>Known bugs</h2>
<p>
The Include Controller has some problems in non-GUI mode.
In particular, it can cause a <code>NullPointerException</code> if there are two include controllers with the same name.
</p>
<p>Once Only controller behaves correctly under a Thread Group or Loop Controller,
but otherwise its behaviour is not consistent (or clearly specified).</p>
<p>
The menu item <menuchoice><guimenuitem>Options</guimenuitem><guimenuitem>Choose Language</guimenuitem></menuchoice>
does not change all the displayed text to the new language.
[The behaviour has improved, but language change is still not fully working]
To override the default local language fully, set the JMeter property "<code>language</code>" before starting JMeter.
</p>
<h2>Incompatible changes</h2>
<p>
When loading sample results from a file, previous results are no longer cleared.
This allows one to merge multiple files.
If the previous behaviour is required,
use the menu item <menuchoice>
<guimenuitem>Run</guimenuitem>
<guimenuitem>Clear</guimenuitem>
<shortcut>
<keycombo>
<keysym>Ctrl</keysym><keysym>Shift</keysym><keysym>E</keysym>
</keycombo>
</shortcut>
</menuchoice> or <menuchoice>
<guimenuitem>Run</guimenuitem>
<guimenuitem>Clear All</guimenuitem>
<shortcut>
<keycombo>
<keysym>Ctrl</keysym><keysym>E</keysym>
</keycombo>
</shortcut>
</menuchoice> before loading the file.
</p>
<p>
The test elements "Save Results to a file" and "Generate Summary Results" are now shown as Listeners.
They were previously shown as Post-Processors, even though they are implemented as Listeners.
</p>
<p>
The Cookie Manager no longer saves incoming cookies as variables by default.
To save cookies as variables, define the property "<code>CookieManager.save.cookies=true</code>".
Also, cookies names are prefixed with "<code>COOKIE_</code>" before they are stored (this avoids accidental corruption of local variables)
To revert to the original behaviour, define the property "<code>CookieManager.name.prefix= </code>" (one or more spaces).
</p>
<p>
The Counter element is now shown as a Configuration element.
It was previously shown as a Pre-Processor, even though it is implemented as a Config item.
</p>
<p>
The above changes only affect the icons that are displayed and the locations in the GUI pop-up menus.
They do not affect test plans or test behaviour.
</p>
<p>
The PreProcessors are now invoked directly by the JMeterThread class,
rather than by the TestCompiler#configureSampler() method. (JMeterThread handles the PostProcessors).
This does not affect test plans or behaviour, but could perhaps affect 3rd party add-ons (very unlikely).
</p>
<p>
Moved the Scoping Rules sub-section from Section 3. "Building a Test Plan" to Section 4. "Elements of a test plan"
</p>
<p>
The While controller now trims leading and trailing spaces from the condition value before it is compared
with <code>LAST</code>, blank or false.
</p>
<p>
The "threadName" variable in the _jexl() and __javaScript() functions was previously misspelt as "theadName".
</p>
<p>
The following deprecated methods were removed from JOrphanUtils: booleanToString(boolean) and valueOf(boolean).
Java 1.4+ has these methods in the Boolean class.
</p>
<p>
The TestElement interface has some new methods:
<ul>
<li>void setProperty(String key, String value, String dflt)</li>
<li>void setProperty(String key, boolean value, boolean dflt)</li>
<li>void setProperty(String key, int value)</li>
<li>void setProperty(String key, int value, int dflt)</li>
<li>int getPropertyAsInt(String key, int defaultValue)</li>
</ul>
These are implemented in the AbstractTestElement class which all elements should extend so this is unlikely to cause a problem.

<!-- =================== -->
<h2>Version 2.3.2</h2>
<h3>Summary of main changes</h3>
<h4>Bug fixes</h4>
<p>
Version 2.3.1 changed the way binary and text content types were determined as far as the View Results Tree Listener was concerned:
originally everything except "image/" content types were considered text, but 2.3.1 introduced a check
for specific content types. This has caused problems,
as several popular types were omitted and these were no longer shown by default in the Response tab.
Rather than try to list all the possible text types, JMeter now just checks for the following binary types:
<ul>
<li>image/*</li>
<li>audio/*</li>
<li>video/*</li>
</ul>
All other types are now assumed to be text.
</p>
<p>
JMeter 2.3.1 introduced a bug in the Cookie Manager
- if "Clear Cookie each iteration" was selected, all threads would see the same cookies.
This bug has been corrected.
</p>
<h4>Improvements</h4>
<p>
The Proxy server can now record binary requests.
By default the content types
application/x-amf and application/x-java-serialized-object
will be treated as binary and saved in a file.
To change the content types, update the property <b>proxy.binary.types</b>.
</p>
<p>
The CSV Dataset configuration element has new file sharing options: per thread group, per thread, per identifier.
This allows for more flexible file processing, e.g. each thread can process the same data in the same order.
</p>
<p>Switch Controller now works properly with functions and variables,
and the condition can now be a name instead of a number.
Simple Controller now works properly under a While Controller</p>
<p>CSV fields in JTL files can now contain delimiters.
CSV and XML files can now contain additional variables (define the JMeter property <b>sample_variables</b>).</p>
<p>Response Assertion can now match on substrings (i.e. not regular expression).
Regex extractor can operate on variables.</p>
<p>
XPath processing is improved; Tidy errors are handled better.
</p>
<p>Save Table Data buttons added to Summary and Aggregate reports to allow easy saving of the calculated data.</p>
<p>
HTTP samplers can now save just the MD5 hash of responses, rather than the entire response.
As a special case, if the HTTP Sampler path starts with "http://" or "https://" then this is used as the full URL,
overriding the host and port fields.
The HTTP Samplers can now POST multiple files.
Webservice(SOAP) Sampler can now load local WSDL files using the "file:" protocol.
</p>
<p>
A simple HTTP Cache Manager has been added. This needs further development.
</p>
<p>
View Results Tree Listener now uses Tidy to display XML.
This should allow more content to be displayed succesfully.
It also avoids the need to download remote DTD files, which can slow the rendering considerably.
</p>
<p>
MailReader sampler now supports POP3S and IMAPS protocols. Individual mails are now added as sub-samples.
</p>
<p>
Various improvements to the BSF Sampler: now supports Jexl, and Javascript bug works properly.
Added BSF PreProcessor, PostProcessor and Assertion test elements.
All now have access to "props" JMeter Properties object.
</p>
<p>Number of classes loaded in non-GUI mode is much reduced.</p>
<h3>Known bugs</h3>
<p>
The Include Controller has some problems in non-GUI mode.
In particular, it can cause a NullPointerException if there are two include controllers with the same name.
</p>
<p>Once Only controller behaves OK under a Thread Group or Loop Controller,
but otherwise its behaviour is not consistent (or clearly specified).</p>
<p>
The menu item Options / Choose Language does not change all the displayed text to the new language.
To override the default local language, set the JMeter property "language" before starting JMeter.
</p>
<h3>Incompatible changes</h3>
<ul>
<li>
To reduce the number of classes loaded in non-GUI mode,
Functions will only be found if their classname contains the string
'.functions.' and does not contain the string '.gui.'.
All existing JMeter functions conform to this restriction.
To revert to earlier behaviour, comment or change the properties classfinder.functions.* in jmeter.properties.
</li>
<li>The reference value parameter for intSum() is now optional.
As a consequence, if a variable name is used, it must not be a valid integer.</li>
<li>The supplied TCPClient implementation no longer treats tcp.eolByte=0 as special.
To skip EOL checking, set tcp.eolByte=1000 (or some other value which is not a valid byte)
</li>
<li>
Leading and trailing spaces are trimmed from variable names in function calls.
For example, ${__Random(1,63,&nbsp;LOTTERY&nbsp;)} will use the variable 'LOTTERY' rather than '&nbsp;LOTTERY&nbsp;'.
</li>
<li>
Synchronization has been removed from the RunningSample class (it was not fully threadsafe anyway).
Developers of 3rd party add-ons that use the class may need to synchronize access.
</li>
</ul>

<!-- =================== -->
<h3>Version 2.3.1</h3>
<h4>Summary of changes</h4>
<h5>JMeter Proxy</h5>
<p>
The Proxy spoof function was broken in 2.3; it has been fixed.
Spoof now supports an optional parameter to limit spoofing to particular URLs.
This is useful for HTTPS pages that have insecure content - e.g. images/stylesheets may be accessed using HTTP.
Spoofed responses now drop the default port (443) from https links to make them work better.
</p>
<p>
Ignored proxy samples are now visible in Listeners - the label is enclosed in [ and ] as an indication.
Proxy documentation has been improved.
</p>
<h5>GUI changes</h5>
<p>The Add menus show element types in the order in which they are processed
- see <a href="usermanual/test_plan.html#executionorder">Test Plan Execution Order</a>.
It is no longer possible to add test elements to inappropriate parts of the tree
- e.g. samplers cannot be added directly under a test plan.
This also applies to Paste and drag and drop.
</p>
<p>
The File menu now supports a "Revert" option, which reloads the current file.
Also the last few file names used are remembered for easy reloading.
</p>
<p>
The Options Menu now supports Collapse All and Expand All items to collapse and expand the test tree.
</p>
<h5>Remote testing</h5>
<p>
The JMeter server now starts the RMI server directly (by default).
This simplifies testing, and means that the RMI server will be stopped when the server stops.
</p>
<p>
Functions can now be used in Listener filenames (variables do not work).
</p>
<p>
Command-line option -G can now be used to define properties for remote servers.
Option -X can be used to stop a remote server after a non-GUI run.
Server can be set to automatically exit after a single test (set property server.exitaftertest=true).
</p>
<h5>Other enhancements</h5>
<p>
JMeter startup no longer loads as many classes; this should reduce memory requirements.
</p>
<p>
Parameter and file support added to all BeanShell elements.
Javascript function now supports access to JMeter objects;
Jexl function always did have access, but the documentation has now been included.
New functions __eval() and __evalVar() for evaluating variables.
</p>
<p>
CSV files with the correct header column names are now automatically recognised when loaded.
There is no need to configure the properties.
</p>
<p>
The hostname can now be saved in CSV and XML output files.
New "Successes only" option added when saving result files.
Errors / Successes only option is now supported when loading XML and CSV files.
</p>
<p>
General documentation improvements.
</p>
<h5>HTTP</h5>
<p>PUT and DELETE should now work properly.
Cookie Manager no longer clears manually entered cookies.
</p>
<p>Now handles the META tag http-equiv charset</p>
<h5>JDBC</h5>
<p>JDBC Sampler now allows INOUT and OUT parameters for Called procedures.
JDBC Sampler now allows per-thread connections - set Max Connections = 0 in JDBC Config.
</p>

<!-- ========================================================= -->
<h4>Incompatible changes</h4>
<ul>
<li>JMeter server now creates the RMI registry by default.
If the RMI registry has already been started externally, this will generate a warning message, but the server will continue.
This should not affect JMeter testing.
However, if you are also using the RMI registry for other applications there may be problems.
For example, when the JMeter server shuts down it will stop the RMI registry.
Also user-written command files may need to be adjusted (the ones supplied with JMeter have been updated).
To revert to the earlier behaviour, define the JMeter property: <b>server.rmi.create=false</b>.
</li>
<li>The Proxy server removes If-Modified-Since and If-None-Match headers from generated Header Managers.
To revert to the previous behaviour, define the property proxy.headers.remove with no value</li>

</ul>
<h3>Version 2.3RC3</h3>
<h4>Known problems/restrictions:</h4>
<p>
The JMeter remote server does not support multiple concurrent tests - each remote test should be run in a separate server.
Otherwise tests may fail with random Exceptions, e.g. ConcurrentModification Exception in StandardJMeterEngine.
See <bugzilla>43168</bugzilla>.
</p>
<p>
The default HTTP Request (not HTTPClient) sampler may not work for HTTPS connections via a proxy.
This appears to be due to a Java bug, see <bugzilla>39337</bugzilla>.
To avoid the problem, try a more recent version of Java, or switch to the HTTPClient version of the HTTP Request sampler.
</p>
<p>Transaction Controller parent mode does not support nested Transaction Controllers.
Doing so may cause a Null Pointer Exception in TestCompiler.
</p>
<p>Thread active counts are always zero in CSV and XML files when running remote tests.
</p>
<p>The property file_format.testlog=2.1 is treated the same as 2.2.
However JMeter does honour the 3 testplan versions.</p>
<p>
<bugzilla>22510</bugzilla> - JMeter always uses the first entry in the keystore.
</p>
<p>
Remote mode does not work if JMeter is installed in a directory where the path name contains spaces.
</p>
<p>
BeanShell test elements leak memory.
This can be reduced by using a file instead of including the script in the test element.
</p>
<p>
Variables and functions do not work in Listeners in client-server (remote) mode so they cannot be used
to name log files in client-server mode.
</p>
<p>
CSV Dataset variables are defined after configuration processing is completed,
so they cannot be used for other configuration items such as JDBC Config.
(see <bugzilla>40394</bugzilla>)
</p>
<h4>Summary of changes (for more details, see below)</h4>
<p>
Some of the main enhancements are:
</p>
<ul>
<li>Htmlparser 2.0 now used for parsing</li>
<li>HTTP Authorization now supports domain and realm</li>
<li>HttpClient options can be specified via httpclient.parameters file</li>
<li>HttpClient now behaves the same as Java Http for SSL certificates</li>
<li>HTTP Mirror Server to allow local testing of HTTP samplers</li>
<li>HTTP Proxy supports XML-RPC recording, and other proxy improvements</li>
<li>__V() function allows support of nested variable references</li>
<li>LDAP Ext sampler optionally parses result sets and supports secure mode</li>
<li>FTP Sampler supports Ascii/Binary mode and upload</li>
<li>Transaction Controller now optionally generates a Sample with subresults</li>
<li>HTTPS session contexts are now per-thread, rather than shared. This gives better emulation of multiple users</li>
<li>BeanShell elements now support ThreadListener and TestListener interfaces</li>
<li>Coloured icons in Tree View Listener and elsewhere to better differentiate failed samples.</li>
</ul>
<p>
The main bug fixes are:
</p>
<ul>
<li>HTTPS (SSL) handling now much improved</li>
<li>Various Remote mode bugs fixed</li>
<li><keycombo><keysym>Control</keysym><keysym>C</keysym></keycombo>
and <keycombo><keysym>Control</keysym><keysym>V</keysym></keycombo> now work in the test tree</li>
<li>Latency and Encoding now available in CSV log output</li>
<li>Test elements no longer default to previous contents; test elements no longer cleared when changing language.</li>
</ul>
<h4>Incompatible changes (usage):</h4>
<p>
<b>N.B. The javax.net.ssl properties have been moved from jmeter.properties to system.properties,
and will no longer work if defined in jmeter.properties.</b>
<br></br>
The new arrangement is more flexible, as it allows arbitrary system properties to be defined.
</p>
<p>
SSL session contexts are now created per-thread, rather than being shared.
This generates a more realistic load for HTTPS tests.
The change is likely to slow down tests with many SSL threads.
The original behaviour can be enabled by setting the JMeter property:
<pre>
https.sessioncontext.shared=true
</pre>
</p>
<p>
The LDAP Extended Sampler now uses the same panel for both Thread Bind and Single-Bind tests.
This means that any tests using the Single-bind test will need to be updated to set the username and password.
</p>
<p>
<bugzilla>41140</bugzilla>: JMeterThread behaviour was changed so that PostProcessors are run in forward order
(as they appear in the test plan) rather than reverse order as previously.
The original behaviour can be restored by setting the following JMeter property:
<br/>
jmeterthread.reversePostProcessors=true
</p>
<p>
The HTTP Authorization Manager now has extra columns for domain and realm,
so the temporary work-round of using '\' and '@' in the username to delimit the domain and realm
has been removed.
</p>
<p>
<keycombo><keysym>Control</keysym><keysym>Z</keysym></keycombo> no longer used for Remote Start All - this
now uses <keycombo><keysym>Control</keysym><keysym>Shift</keysym><keysym>R</keysym></keycombo>
</p>
<p>
HttpClient now uses pre-emptive authentication.
This can be changed by setting the following:
<pre>
jmeter.properties:
httpclient.parameters.file=httpclient.parameters
httpclient.parameters:
http.authentication.preemptive$Boolean=false
</pre>
</p>
<p>
The port field in HTTP Request Defaults is no longer ignored for https samplers if it is set to 80.
</p>
<h4>Incompatible changes (development):</h4>
<p>
<b>N.B.</b>The clear() method was defined in the following interfaces: Clearable, JMeterGUIComponent and TestElement.
The methods serve different purposes, so two of them were renamed:
the Clearable method is now clearData() and the JMeterGUIComponent method is now clearGui().
3rd party add-ons may need to be rebuilt.
</p>
<p>
Calulator and SamplingStatCalculator classes no longer provide any formatting of their data.
Formatting should now be done using the jorphan.gui Renderer classes.
</p>
<p>
Removed deprecated method JMeterUtils.split() - use JOrphanUtils version instead.
</p>
<p>
Removed method saveUsingJPEGEncoder() from SaveGraphicsService.
It was unused so far, and used the only Sun-specific class in JMeter.
</p>

<h3>Version 2.2</h3>
<h4>Incompatible changes:</h4>
<p>
The time stamp is now set to the sampler start time (it was the end).
To revert to the previous behaviour, change the property <b>sampleresult.timestamp.start</b> to false (or comment it)
</p>
<p>The JMX output format has been simplified and files are not backwards compatible</p>
<p>
The JMeter.BAT file no longer changes directory to JMeter home, but runs from the current working directory.
The jmeter-n.bat and jmeter-t.bat files change to the directory containing the input file.
</p>
<p>
Listeners are now started slightly later in order to allow variable names to be used.
This may cause some problems; if so define the following in jmeter.properties:
<br/>
jmeterengine.startlistenerslater=false
</p>
<p>
The GUI now expands the tree by default when loading a test plan.
This can be disabled by setting the JMeter property <b>onload.expandtree=false</b>
</p>

<h3>Version 1.5</h3>
<ul>
<li>Abstracted out the concept of the Sampler, SamplerController, and TestSample.
A Sampler represents code that understands a protocol (such as HTTP,
or FTP, RMI, SMTP, etc..). It is the code that actually makes the
connection to whatever is being tested. A SamplerController
represents code that understands how to organize and run a group
of test samples. It is what binds together a Sampler and its test
samples and runs them. A TestSample represents code that understands
how to gather information from the user about a particular test.
For a website, it would represent a URL and any information to be sent
with the URL.</li>
<li>The UI has been updated to make entering test samples more convenient.</li>
<li>Thread groups have been added, allowing a user to setup multiple test to run
concurrently, and to allow sharing of test samples between those tests.</li>
<li>It is now possible to save and load test samples.</li>
<li>&hellip; and many more minor changes/improvements &hellip;</li>
