<p>JMS Point-to-Point sampler has been enhanced with <code>read</code>, <code>browse</code>, <code>clear</code> options.
<figure width="1080" height="489" image="changes/4.0/jmsptp_communication_styles.png"></figure></p>
<p>Best property values are now selected on many Test Elements to ensure best practices are the defaults:
<ul>
<li>Newly added <code>If Controller</code> now uses by default Expression which is the most performing option.
<figure width="716" height="248" image="changes/4.0/if_controller_condition.png"></figure>
<figure width="717" height="251" image="changes/4.0/if_controller_expression.png"></figure></li>

<figure width="346" height="49" image="changes/4.0/jsr223_cache_compilation.png"></figure></li>
</ul>
</p>
<p><a href="usermanual/component_reference.html#Loop_Controller"><code>Loop controller</code></a> and
<a href="usermanual/component_reference.html#ForEach_Controller"><code>ForEach Controller</code></a>
now expose their current iteration as a variable named <code>__jm__&lt;Name of your element&gt;__idx</code> that
you can use like this for example for a Loop Controller named <code>MyLoopController</code>:
<source>${__jm__&lt;MyLoopController&gt;__idx}</source>.
See <bugzilla>61802</bugzilla></p>
<p>Cookies are now shown in View Results Tree during recording. They were previously always shown as empty.</p>

<figure width="909" height="617" image="changes/4.0/response_assertion_enhancements.png"></figure></p>
<ch_title>UX improvements</ch_title>
<p>JMeter now uses <a href="https://github.com/bulenkov/Darcula">Darcula LAF</a> by default</p>
<p>Workbench has been dropped from UI, you can now use Non Test Elements as immediate children of Test Plan.

<figure width="772" height="315" image="changes/4.0/function_helper_dialog_enhancements.png"></figure></li>
<li>Switch Controller trims text to avoid issues when a space is introduced before/after name</li>
<li>Test Plan is now saved before running the test plan</li>
</ul>
<ch_title>Functions</ch_title>
<p>New Function <a href="usermanual/functions.html#__digest"><code>__digest</code></a> provides easy computing of SHA-XXX, MDX hashes:
<source>${__digest(MD5,Apache JMeter 4.0 rocks !,,,)}</source> will return <code>0e16c3ce9b6c9971c69ad685fd875d2b</code></p>
<p>New Function <a href="usermanual/functions.html#__dateTimeConvert"><code>__dateTimeConvert</code></a> provides easy conversion between date formats:

<ch_title>Configuration of JMeter environment</ch_title>
<p>JVM settings for the JMeter start scripts can be placed in a separate file (<code>bin/setenv.sh</code> on Unix
and <code>bin\setenv.bat</code> on Windows), that gets called on startup. The startup script
itself does not have to be edited anymore.</p>
<!-- =================== Incompatible changes =================== -->
<ch_section>Incompatible changes</ch_section>
<ul>
<li><code>Start time</code> and <code>End date</code> of Thread Group have been removed, see <bugzilla>61549</bugzilla></li>
<li>In distributed testing, mode <code>Hold</code> has been removed. Use alternative and more efficient modes</li>
<li>For 3<sup>rd</sup> party plugins, the following method in <code>org.apache.jmeter.gui.tree.JMeterTreeNode</code> has been dropped for migration to Java 9 (<bugzilla>61529</bugzilla>)
<source>public Enumeration&lt;JMeterTreeNode&gt; children()</source>
</li>
<li><code>tearDown Thread Group</code> will now run on stop and shutdown of a test by default. If you don't want this behaviour,
uncheck <code>Run tearDown Thread Groups after shutdown of main threads</code> on <code>Test Plan</code> element, see <bugzilla>61656</bugzilla></li>
<li>Properties <code>sampleresult.getbytes.headers_size</code> and <code>sampleresult.getbytes.body_real_size</code> have been dropped, see <bugzilla>61587</bugzilla></li>
<li>JMeter will now save your test plan whenever you run it. This behaviour can be controlled by property <code>save_automatically_before_run</code>, see <bugzilla>61731</bugzilla></li>
<li>Workbench element has been dropped, you now directly add <code>Non Test Element</code> as children of Test Plan. When loading a Test Plan that contains the element
JMeter will move the <code>Mirror Server</code>, <code>Property Display</code> and HTTP(s) <code>Test Script Recorder</code> elements as direct children of Test Plan. For
any other element, it will create a <code>Test Fragment</code> element called <code>Workbench Test Fragment and move the elements in it</code>.</li>
<li>Following classes have been dropped (<code>org.apache.jmeter.functions.util.ArgumentEncoder</code>, <code>org.apache.jmeter.functions.util.ArgumentDecoder</code>), see <pr>335</pr></li>
<li>In JMS Point-to-Point sampler, setting timeout to 0 will now mean infinite timeout while previously it would be switched to 2000 ms, see <bugzilla>61829</bugzilla></li>
<li>When Assertions are at different scopes, they are executed starting with the most OUTER one to the most INNER one. See <bugzilla>61846</bugzilla></li>
<li>JMeter now starts by default using English locale. This change is due to missing translations in many supported languages.
You can change locale by modifying in jmeter and jmeter.bat (or preferably setenv.sh/setenv.bat) the <code>JVM_ARGS</code> system property values.
We'd also be very grateful if you can contribute translations in supported languages.
</li>
<li>SwitchController now trims by default the content of switch to avoid issue related to unwanted spaces. See <bugzilla>61771</bugzilla></li>
<li>JMeter JVM heap settings have changed from <code>-Xms512m -Xmx512m</code> to <code>-Xms1g -Xmx1g</code></li>
</ul>

<!-- =================== Known bugs or issues related to JAVA Bugs =================== -->
<ch_section>Known problems and workarounds</ch_section>
<ul>
<li>View Results Tree may freeze rendering large response particularly if this response has no spaces, see <bugzilla>60816</bugzilla>.
This is due to an identified Java Bug <a href="https://bugs.openjdk.java.net/browse/JDK-8172336">UI stuck when calling <code>JEditorPane.setText()</code> or <code>JTextArea.setText()</code> with long text without space</a>.
</li>
</ul>
<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 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>
<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.
</li>
