<p>
This release is a minor bugfix release. Please see the <a href="changes_history.html">Changes history page</a>
to view the last release notes of version 5.2.1.
</p>
<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>

<a href="./images/screenshots/changes/5.3/tree_theme_intellij.png"><img src="./images/screenshots/changes/5.3/tree_theme_intellij.png" width="223" height="246" alt="JMeter tree with Darklaf IntelliJ 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>
<h2 class="ch_section" id="Incompatible changes">Incompatible changes</h2>
<ul>
<li>Default value of <span class="code">httpclient4.time_to_live</span> has been modified from <span class="code">2000</span> to <span class="code">60000</span>,
this means HTTP connections will live longer than before. This
has impact on connection creation and SSL handshake, see <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=64289">

</li>
<li>The update to Groovy 3 (<a href="https://github.com/apache/jmeter/pull/590">

<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 <span class="code">0</span> (see <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=55510">
Bug
55510</a>).
</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>
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:
<pre class="source">JAVA_HOME/jre/lib/security/java.security</pre>

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 JDK8_u45 or later.

<li>
View Results Tree may fail to display some HTML code under HTML renderer, see <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=54586">
Bug
54586</a>.
This is due to a known Java bug which fails to parse "<span class="code">px</span>" 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>
JTable selection with keyboard (<span class="keycombo"><span class="keysym">SHIFT</span>&nbsp;+&nbsp;<span class="keysym">up/down</span></span>) 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.
</li>
<li>
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"
