<h2 class="ch_section" id="New and Noteworthy">New and Noteworthy</h2>
<h2 class="ch_section" id="Improve Report/Dashboard">Improve Report/Dashboard</h2>
The Dashboard has been improved with 3 new graphs and 1 summary table:
<ul>
<li>Connect Time over Time graph : <figure><a href="./images/screenshots/dashboard/report_connect_time_over_time.png"><img src="./images/screenshots/dashboard/report_connect_time_over_time.png" width="1635" height="520" alt=""></a><figcaption></figcaption></figure></li>

</ul>
<h2 class="ch_section" id="New Metrics">New Metrics</h2>
A new <span class="code">sent_bytes</span> metric has been introduced which reports the bytes sent to server.<br>
Another metric <span class="code">connect_time</span> has been enabled by default in this version
<h2 class="ch_section" id="Handling Big responses">Handling Big responses</h2>
JMeter is now able to handle in terms of metrics responses bigger than 2GB, limit has been increased to 9223372 TB.<br>
To handle such big responses, it can also now truncate part of the response to avoid overflooding memory. See <span class="code">httpsampler.max_bytes_to_store_per_request</span> property.
<h2 class="ch_section" id="New __groovy function">New <span class="code">__groovy</span> function</h2>
Introduce a new function <span class="code">__groovy</span> that enables Groovy functions. This can be handy, as JavaScript can be quite slow (same for BeanShell), when used in highly concurrent test plans.
<h2 class="ch_section" id="Use Groovy as default for JSR-223 elements">Use Groovy as default for JSR-223 elements</h2>
Groovy is now set as the default language for JSR-223 elements. If you want to use another of the supported language, you have to make an explicit choice.
<div class="clear"></div><div class="note">By default <span class="code">Cache compiled script if available</span> is not checked by default although we advise you to check it and ensure you don't use <span class="code">${varName}</span> syntax to access JMeter variables but <span class="code">vars.get("varName")</span> instead.</div><div class="clear"></div>
<h2 class="ch_section" id="Formatted HTML source view in Results Tree View">Formatted HTML source view in Results Tree View</h2>
The HTML source code in the Results Tree View can now be viewed formatted. This is extremely useful, if the code of the webpage has been stripped of all superfluous whitespace.

<h3 class="ch_title">Core improvements</h3>
<ul>
<li>Various GUI and UX fixes</li>
<li>Memory usage improvements</li>
<li>JDBC Request is now able to return Blob/Clob and computes latency and connect time</li>
<li>CSS Parsing introduced in 3.0 has been optimized by introduction of a parsing cache</li>
</ul>
<h3 class="ch_title">Documentation improvements</h3>
<ul>
<li>Documentation review and improvements for easier startup</li>
<li>New <a href="usermanual/properties_reference.html">properties reference</a> documentation section</li>
</ul>
<h2 class="ch_section" id="Incompatible changes">Incompatible changes</h2>
<ul>
<li>A cache for CSS Parsing of URLs has been introduced in this version, it is enabled by default. It is controlled by property <span class="code">css.parser.cache.size</span>. It can be disabled by setting its value to <span class="code">0</span>. See <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=59885">
Bug
59885</a></li>
<li>ThroughputController defaults have changed. Now defaults are Percent Executions which is global and no more per user. See <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=60023">
Bug
60023</a></li>
<li>Since version 3.1, HTML report ignores empty <span class="code">Transaction Controller</span> (possibly generated by <span class="code">If Controller</span> or <span class="code">Throughput Controller</span>) when computing metrics. This provides more accurate metrics</li>
<li>Since version 3.1, Summariser ignores SampleResults generated by <span class="code">Transaction Controller</span> when computing the live statistics, see <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=60109">
Bug
60109</a></li>
<li>Since version 3.1, when using Stripped modes (by default <span class="code">StrippedBatch</span> is used), response will be stripped also for failing SampleResults, you can revert this to previous behaviour by setting <span class="code">sample_sender_strip_also_on_error=false</span> in <span class="code">user.properties</span>, see <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=60137">
Bug
60137</a></li>
<li>Since version 3.1, <span class="code">jmeter.save.saveservice.connect_time</span> property value is <span class="code">true</span>, meaning CSV file for results will contain an additional column containing connection time, see <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=60106">
Bug
60106</a></li>
<li>Since version 3.1, Random Timer subclasses (Gaussian Random Timer, Uniform Random Timer and Poisson Random Timer) implement interface <span class="code"><a href="./api/org/apache/jmeter/timers/ModifiableTimer.html">org.apache.jmeter.timers.ModifiableTimer</a></span></li>
<li>Since version 3.1, if you don't select any language in JSR223 Test Elements, Apache Groovy language will be used. See <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=59945">
Bug
59945</a></li>
<li>Since version 3.1, CSV DataSet now trims variable names to avoid issues due to spaces between variables names when configuring CSV DataSet. This should not have any impact for you unless you use space at the begining or end of your variable names. See <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=60221">
Bug
60221</a></li>
<li>Since version 3.1, HTTP Request is able when using HttpClient4 (default) implementation to handle responses bigger than <span class="code">2147483647</span> Bytes, that is 2GB. To allow this two properties have been introduced:
<ul>
<li><span class="code">httpsampler.max_bytes_to_store_per_request</span> (defaults to 10MB) will control what is held in memory. By default JMeter will only keep in memory the first 10MB of a response. If you have responses larger than this value and use assertions that are after the first 10MB, then you must increase this value</li>
<li><span class="code">httpsampler.max_buffer_size</span> will control the buffer used to read the data. Previously JMeter used a buffer equal to Content-Length header which could lead to failures and make JMeter less resistant to faulty applications, but note this may impact response times and give slightly different results
than previous versions if your application returned a Content-Length header higher than current default value (65KB) </li>
</ul>
See <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=53039">

<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 there is a <a href="http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6396599 ">bug in Java</a>
on some Linux systems that manifests itself as the following error when running the test cases or JMeter itself:
<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>
<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>
See <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=56357">
Bug
56357</a> 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 JDK7_u79, JDK8_u45 or later.
</li>
<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>
<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.
