this version (but is still deprecated).</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>
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 <span class="code">md2WithRSAEncryption</span>) or with a SSL certificate with a size lower than 1024 bits.
This error is related to increased security in Java 8+.
<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:

Since Java 11 the JavaScript implementation <a href="https://openjdk.java.net/jeps/335">Nashorn has been deprecated</a>.
Java will emit the following deprecation warnings, if you are using JavaScript based on Nashorn.
<pre class="source">
Warning: Nashorn engine is planned to be removed from a future JDK release
</pre>
To silence these warnings, add <span class="code">-Dnashorn.args=--no-deprecation-warning</span> to your Java arguments.
That can be achieved by setting the enviroment variable <span class="code">JVM_ARGS</span>
<pre class="source">
export JVM_ARGS="-Dnashorn.args=--no-deprecation-warning"
</pre>
</li>
<li>
With Java 15 the JavaScript implementation <a href="https://openjdk.java.net/jeps/372">Nashorn has been removed</a>. To add back a JSR-223 compatible JavaScript engine you have two options:
<dl>
<dt>Use Mozilla Rhino</dt>
<dd>Copy <a href="https://github.com/mozilla/rhino/releases/download/Rhino1_7_13_Release/rhino-engine-1.7.13.jar">rhino-engine-1.7.13.jar</a> into <span class="code">$JMETER_HOME/lib/ext</span>.</dd>
<dt>Use OpenJDK Nashorn</dt>
<dd>
The OpenJDK Nashorn implementation comes as a module. To use it, you will have to download it and add it to the module path. A hacky way to download the version 15.0 and its dependencies and set the module path is outlined below:
<pre class="source">
mkdir lib/modules
pushd lib/modules
wget https://repo1.maven.org/maven2/org/openjdk/nashorn/nashorn-core/15.0/nashorn-core-15.0.jar

<h3 class="ch_title">UX improvements</h3>
Added <a href="https://github.com/weisJ/darklaf">Darklaf</a> look and feel that improves several components.
<p>Tree indentation level is easier to follow:</p>
<figure>
<a href="./images/screenshots/changes/5.3/tree_theme_darcula.png"><img src="./images/screenshots/changes/5.3/tree_theme_darcula.png" width="224" height="247" alt="JMeter tree with Darklaf Darcula theme"></a>

<figcaption>JMeter tree with Darklaf IntelliJ theme</figcaption>
</figure>
<p>New look and feel themes. Light: IntellJ, Solarized Light, HighContrast Light.
Dark: OneDark, Solarized Dark, HighContrast Dark.
</p>
<p>When an element in tree is disabled, all its descendants are shown in gray.
For instance, <span class="code">While Contoller</span> is disabled in the following tree, so its children
are gray. It is purely a UI change, and the behavior is not altered.
</p>
<figure>
<a href="./images/screenshots/changes/5.3/disabled_subtree.png"><img src="./images/screenshots/changes/5.3/disabled_subtree.png" width="223" height="256" alt="While controller is disabled, so its children are gray"></a>
<figcaption>While controller is disabled, so its children are gray</figcaption>
</figure>
<p>Tree context menu is shown even in case the node selection is changed. Previously
the popup did disappear and it was required to select a node first and only then launch popup.</p>
<p>Look and feel can now be updated without a restart</p>
<p>Use <span class="keycombo"><span class="keysym">CTRL</span>&nbsp;+&nbsp;<span class="keysym">ALT</span>&nbsp;+&nbsp;<span class="keysym">wheel</span></span> for zooming
fonts. Previous shortcut was <span class="keycombo"><span class="keysym">CTRL</span>&nbsp;+&nbsp;<span class="keysym">SHIFT</span>&nbsp;+&nbsp;<span class="keysym">wheel</span></span>,
however, it conflicted with horizontal scrolling.</p>
<p>In-app zoom is more consistent (e.g. sometimes not all the labels or even panels were scaled).
For instance: log viewer, JSR223 code editor were not previously scaled with zoom-in/out feature</p>
<p>Tree context menu is shown for the full row, not for the label only</p>
<p>Undo and redo support for editable fields. Keystrokes are <span class="keycombo"><span class="keysym">CTRL</span>&nbsp;+&nbsp;<span class="keysym">Z</span></span> /
<span class="keycombo"><span class="keysym">CTRL</span>&nbsp;+&nbsp;<span class="keysym">SHIFT</span>&nbsp;+&nbsp;<span class="keysym">Z</span></span>, or
<span class="keycombo"><span class="keysym">CMD</span>&nbsp;+&nbsp;<span class="keysym">Z</span></span>/
<span class="keycombo"><span class="keysym">CMD</span>&nbsp;+&nbsp;<span class="keysym">SHIFT</span>&nbsp;+&nbsp;<span class="keysym">Z</span></span> depending on the operating system.
Undo is implemented on a field level basis (each fields has its own history), and the history is
invalidated when tree selection changes.</p>
<p>Mark the currently selected language in the options menu.</p>
<p>Mark the currently selected log level in the options menu.</p>
<p>Rework of many Test Element UI (JUnit Request, ForEach Controller, If Controller, Throughput Controller, WhileController,
Counter Config, XPath2 Extractor, Function Helper Dialog, Search popup, JMS Elements)</p>

WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0
x80000002. Windows RegCreateKeyEx(&hellip;) returned error code 5.

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

This error is related to increased security in Java 8+.
<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.

Since Java 11 the JavaScript implementation <a href="https://openjdk.java.net/jeps/335">Nashorn has been deprecated</a>.
Java will emit the following deprecation warnings, if you are using JavaScript based on Nashorn.

To silence these warnings, add <span class="code">-Dnashorn.args=--no-deprecation-warning</span> to your Java arguments.

<ul>
<li>Various bug fixes have been implemented, like gathering the correct headers when recording requests through the HTTP(S) Test Script Recorder using HTTPS</li>
<li>In version 5.0, JMeter was changed to rename Sub results using a custom Naming Policy (<a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=62550">
Bug
62550</a>). This change could be annoying for Functional Testing, a new property
<span class="code">subresults.disable_renaming=true</span> has been introduced to revert if needed to previous behaviour. An alternative is to check <span class="code">Functional Test Mode</span> in Test Plan, see <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=63055">

</p>
<p>A new <span class="code">Tools</span> menu has been introduced to collect those entries,
that are used for general usage around JMeter, like:
<ul>
<li>
<span class="code">Function Helper Dialog</span>
</li>
<li>
<span class="code">Export transactions for report</span>
</li>
<li>
<span class="code">Generate Schematic View</span> which provides an overview as HTML of the Test plan</li>
<li>
<span class="code">Import from cURL</span> which allows you to create or update your test plan by importing a cURL command</li>
<li>
<span class="code">Compile JSR223 Test Elements</span>
</li>
<li>
<span class="code">Create a heap dump</span>
</li>

<h3 class="ch_title">Scripting / Debugging enhancements</h3>
<ul>
<li>A menu item to compile all JSR223 Elements is now available in <span class="code">Tools</span> menu</li>
</ul>
<h3 class="ch_title">Live Reporting and Web Report</h3>
<ul>
<li>A JSON file containing summary of a load test statistics is now generated when using <span class="code">-e</span> or <span class="code">-g</span> options.</li>
<li>Percentiles computing graphed over time algorithm has been modified to restart for each time slot</li>
<li>More user-friendly behaviour when reporting folder does not exist or is not empty through <span class="code">-f</span> command line option</li>
</ul>
<h2 class="ch_section" id="Incompatible changes">Incompatible changes</h2>
<ul>
<li>In <span class="code">Response Time Percentiles Over Time (successful responses)</span> graph of the HTML report, before this version, percentile computation of each time slot used the percentile data
of previous time slot as a base. Starting with this version, each time slot is independant. See <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=62883">

<li>
<span class="code">ClientJMeterEngine#rsetProperties</span> signature has been changed to use <span class="code">HashMap&lt;String,String&gt;</span> instead of Properties, see <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=63034">
Bug
63034</a>
</li>
<li>A new Menu item <span class="code">Tools</span> has been introduced, some menu items that were in <span class="code">Help</span> menu are now under this new menu item. See <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=63094">
Bug
63094</a>
</li>
<li>
<span class="code">slf4j-ext</span> has been removed from libraries (lib folder) and JMeter pom. It was not used by default and due to CVE-2018-8088 and unavailability of a stable version
containing a fix to this issue, we decided to remove it. If you still needed, you can add it in lib folder.</li>
