<h2 class="ch_section" id="New and Noteworthy">New and Noteworthy</h2>

<h2 class="ch_category">Test plan creation and debugging improvements</h2>
<h3 class="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</h3>
<figure><a href="./images/screenshots/changes/3.0/view_results_tree_search_feature.png"><img src="./images/screenshots/changes/3.0/view_results_tree_search_feature.png" width="846" height="613" alt=""></a><figcaption></figcaption></figure>
<h3 class="ch_title">New JSON Post Processor to better extract data from JSON content using user friendly JSON-PATH syntax</h3>
<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><a href="./images/screenshots/changes/3.0/json_path_extractor.png"><img src="./images/screenshots/changes/3.0/json_path_extractor.png" width="829" height="223" alt=""></a><figcaption></figcaption></figure>
<h3 class="ch_title">New validation feature, in one click run a selection of Thread Groups with <span class="code">1</span> user, no pause and <span class="code">1</span> iteration</h3>
<figure><a href="./images/screenshots/changes/3.0/thread_group_validate.png"><img src="./images/screenshots/changes/3.0/thread_group_validate.png" width="295" height="629" alt=""></a><figcaption></figcaption></figure>
<h3 class="ch_title">JSR223 Test Elements do not require a Cache Compilation Key anymore</h3>
<p>Just check <span class="code">Cache compiled script if available</span> 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><a href="./images/screenshots/changes/3.0/jsr223_cache_compiled.png"><img src="./images/screenshots/changes/3.0/jsr223_cache_compiled.png" width="991" height="606" alt=""></a><figcaption></figcaption></figure>
<h3 class="ch_title">Nashorn can now be used as Javascript engine providing better performance and easier usage</h3>
To enable <a target="_blank" href="http://www.oracle.com/technetwork/articles/java/jf14-nashorn-2126515.html">Nashorn</a>, you need to set in <span class="code">user.properties</span>:
<pre class="source">javascript.use_rhino=false</pre>
<p>Nashorn can be used with Java 8 in the following elements:
</p>
<ul>
<li>IfController</li>
<li>JSR223 Test elements with <span class="code">javascript</span> language selected</li>
<li><span class="code">__javaScript</span> function</li>
</ul>
<h3 class="ch_title">Jexl3 has been integrated. It provides new scripting features and much better documentation</h3>
<a href="http://commons.apache.org/proper/commons-jexl/" target="_blank">JEXL3</a> can now be used thanks to a new function <span class="code">__jexl3</span>.
JEXL is a language very similar to JSTL. 
<h3 class="ch_title">Simplified HTTP Request UI</h3>
<p>A new "<span class="code">Advanced</span>" 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><a href="./images/screenshots/changes/3.0/http_request_basic.png"><img src="./images/screenshots/changes/3.0/http_request_basic.png" width="895" height="674" alt=""></a><figcaption></figcaption></figure>

<h2 class="ch_category">Reporting improvements</h2>

<h3 class="ch_title">New Reporting Feature generating dynamic Graphs in HTML pages (APDEX, Summary report and Graphs)</h3>
<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>

<h3 class="ch_title">BackendListener now allows you to define sampler list as a regular expression</h3>
<p>You can now use a regular expression to select the samplers you want to filter. 
Use parameter: <span class="code">useRegexpForSamplersList=true</span> and put a regex in pararameter <span class="code">samplersList</span>
</p>

<h2 class="ch_category">Protocols and Load Testing improvements</h2>
<h3 class="ch_title">Migration to HttpClient 4.5.2 has been started. Although not completely finished, it improves many areas in JMeter</h3>
<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 <span class="code">HC4CookieHandler</span> in HTTP Cookie Manager component and select <span class="code">standard</span> 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 <span class="code">httpclient4.validate_after_inactivity</span> and <span class="code">httpclient4.time_to_live</span></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 <span class="code">deflate</span> compression management</li>
</ul>
<h3 class="ch_title">Parallel Downloads is now realistic and scales much better:</h3>
<ul>
<li>Parsing of CSS imported files (through <span class="code">@import</span>) 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 <span class="code">httpsampler.embedded_resources_use_md5=true</span></li>
</ul>
<h3 class="ch_title">Introduction of Sample Timeout feature</h3>
<p>This new <a href="./usermanual/component_reference.html#Sample_Timeout">Sample Timeout</a> 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 <span class="code">Debug Sampler</span> and <span class="code">HTTP Request</span> elements.
</p>
<figure><a href="./images/screenshots/changes/3.0/sample_timeout.png"><img src="./images/screenshots/changes/3.0/sample_timeout.png" width="828" height="161" alt=""></a><figcaption></figcaption></figure>

<h3 class="ch_title">JDBC request now uses DBCP2 pool</h3>
<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 '<span class="code">SELECT 1 FROM DUAL</span>' or similar.
</p>

<h2 class="ch_category">UX Improvements:</h2>

<h3 class="ch_title">Better display in HiDPI screens</h3>
<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>
<h3 class="ch_title">New Icon look and Logo</h3>
<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>
<h3 class="ch_title">Lots of fixes of annoying little bugs</h3>
<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>
<h3 class="ch_title">Improved Thread Group UI and related actions (<span class="code">Start</span>, <span class="code">Start No Timers</span>, <span class="code">Validate</span>)</h3>
<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>

<h3 class="ch_title">New shortcuts</h3>
<ul>
<li>Add most used elements
    (<span class="keycombo"><span class="keysym">Ctrl</span>&nbsp;+&nbsp;<span class="keysym">0</span></span>
    &hellip;
    <span class="keycombo"><span class="keysym">Ctrl</span>&nbsp;+&nbsp;<span class="keysym">9</span></span>),

<pre class="source">
 [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 class="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.
</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 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>
You may encounter the following error:
<pre class="source">java.security.cert.CertificateException: Certificates does not conform to algorithm constraints</pre>
 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>
To allow you to perform your HTTPS request, you can downgrade the security of your Java installation by editing 
the Java <span class="code">jdk.certpath.disabledAlgorithms</span> property. Remove the MD2 value or the constraint on size, depending on your case.
<br>
This property is in this file:
<pre class="source">JAVA_HOME/jre/lib/security/java.security</pre>
