 <ch_section>New and Noteworthy</ch_section>
-<p>JMeter now supports Java 17</p>
-
-<p>JMeter 5.5 ships with log4j2 2.17.2</p>
-
-<ch_title>Open Model Thread Group</ch_title>
-
-<p>New component: <code><a href="./usermanual/component_reference.html#Open_Model_Thread_Group">Open Model Thread Group</a></code>
-allows creating load profiles with variable load.</p>
-
-<p>For example, if you need to gradually increase load from <code>0/sec</code> to <code>10/sec</code> during <code>minute</code>
-you could previously use <code>Thread Group + Timer</code> combinations. However, then you need to compute
-the expected number of threads, ensure they are created only when needed, and so on.</p>
-
-<p>With <code>Open Model Thread Group</code> you can configure the same load profile as <code>rate(0/sec) random_arrivals(1&nbsp;minute) rate(10/sec)</code>.
-The thread group would spawn threads as needed to drive the configured load.
-The load profile can use properties, so you can launch the same script with slightly different load levels,
-however, the profile can't be updated while the test is running.
-</p>
-
-<p>The new thread group is experimental in JMeter 5.5, so please feel free to submit your feedback.</p>

-
-<ch_title>Preparing the deprecation of Oro Regex usage</ch_title>
-
-<p>Another experimental feature in JMeter 5.5 is the ability to replace the Oro based Regex implementation
-  by the built-in Java based one. To choose the Java based one, set the JMeter property <code>jmeter.regex.engine</code>
-  to the value <code>java</code>.</p>
-
-<ch_title>Core improvements</ch_title>
-<p>Kotlin language is now used in some core classes and tests (e.g. Open Model Thread Group).
-    JMeter is compiled with <code>apiTarget=1.5</code>, and it ships with <code>kotlin-stdlib</code> 1.6.
-</p>
-
-<p><a href="https://github.com/JetBrains/lets-plot-kotlin">lets-plot-kotlin</a> charting library is added,
-    so it will be easier to refine and create new charts in UI in the future.

+<ch_title>Preparing the deprecation of Oro Regex usage</ch_title>
+
+<p>Another experimental feature in JMeter 5.5 is the ability to replace the Oro based Regex implementation
+  by the built-in Java based one. To choose the Java based one, set the JMeter property <code>jmeter.regex.engine</code>
+  to the value <code>java</code>.</p>
+
+<ch_title>Core improvements</ch_title>
+<p>Kotlin language is now used in some core classes and tests (e.g. Open Model Thread Group).
+    JMeter is compiled with <code>apiTarget=1.5</code>, and it ships with <code>kotlin-stdlib</code> 1.6.
+</p>
+
+<p><a href="https://github.com/JetBrains/lets-plot-kotlin">lets-plot-kotlin</a> charting library is added,
+    so it will be easier to refine and create new charts in UI in the future.

+<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 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>
+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 <code>md2WithRSAEncryption</code>) or with a SSL certificate with a size lower than 1024 bits.
+This error is related to increased security in Java 8+.
+<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>
+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>
+
+<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.

+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.
+<source>
+Warning: Nashorn engine is planned to be removed from a future JDK release
+</source>
+To silence these warnings, add <code>-Dnashorn.args=--no-deprecation-warning</code> to your Java arguments.
+That can be achieved by setting the enviroment variable <code>JVM_ARGS</code>
+<source>
+export JVM_ARGS="-Dnashorn.args=--no-deprecation-warning"
+</source>
+</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_14_Release/rhino-engine-1.7.14.jar">rhino-engine-1.7.14.jar</a> into <code>$JMETER_HOME/lib/ext</code>.</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 (or later) and its dependencies and set the module path is outlined below:
+      <source>
+mkdir lib/modules
+pushd lib/modules
+wget https://repo1.maven.org/maven2/org/openjdk/nashorn/nashorn-core/15.3/nashorn-core-15.3.jar
