> +
> +<ch_title>Smarter Recording of Http Test Plans</ch_title>
> +<p>Test Script Recorder has been improved in many ways</p>
> +<ul>
> +    <li>Better matching of Variables in Requests, making Test Script Recorder variabilize your sampler during recording more versatile</li>
> +    <li>Ability to filter from View Results Tree the Samples that are excluded from recording, this lets you concentrate on recorded Samplers analysis and not bother with useless Sample Results
> +    <figure width="1094" height="647" image="changes/2.12/14_recorder_filter.png"></figure>
> +    </li>
> +    <li>Better defaults for recording, since this version Recorder will number created Samplers letting you find them much easily in View Results Tree.
> +    Grouping of Samplers under Transaction Controller will be smarter making all requests emitted by a web page be children as new Transaction Controller</li>
> +</ul>
> +
> +<ch_title>Support of Webdav requests</ch_title>
> +<p>You can now test against WebDav server using HttpClient4 Implementation of Http Request</p>
> +<figure width="989" height="406" image="changes/2.12/13_webdav.png"></figure>
> +
> +<ch_title>Better handling of embedded resources</ch_title>
> +<p>When download embedded resources is checked, JMeter now uses User Agent header to download or not resources embedded within conditionnal comments as per <a href="http://msdn.microsoft.com/en-us/library/ms537512%28v=vs.85%29.aspx" target="_blank">About conditional comments</a>.</p>
> +
> +<ch_title>Ability to customize Cache Manager (Browser cache simulation) handling of cached resources</ch_title>
> +<p>You can now configure the behaviour of JMeter when a resource is found in Cache, this can be controlled with <i>cache_manager.cached_resource_mode</i> property</p>
> +<figure width="1024" height="314" image="changes/2.12/12_cache_resource_mode.png"></figure>

> +In addition, you can fetch only the message header now.</p>

> +<figure width="796" height="192" image="changes/2.12/06_smtp_sampler.png"></figure>
> +
> +<ch_title>Synchronizing Timer </ch_title>

> +<figure width="546" height="144" image="changes/2.12/09_synchronizing_timer.png"></figure>
> +
> +<ch_title>Performance improvements</ch_title>
> +<p>A big improvement in performances of Functions has been made by lifting useless synchronization. It concerns all functions except __StringFromFile, __XPath and __BeanShell, see <bugzilla>57114</bugzilla></p>
> +<p>__jexl2 performances have been improved to avoid contention point, see <bugzilla>56708</bugzilla></p>
> +
> +<ch_category>GUI Improvements</ch_category>
> +
> +<ch_title>Undo/Redo support</ch_title>
> +<p>Undo / Redo has been introduced and allows user to undo/redo changes made on Test Plan Tree. This feature (ALPHA MODE) is disabled by default, to enable it set property <b>undo.history.size=25</b> </p>
> +<figure width="1024" height="56" image="changes/2.12/10_undo_redo.png"></figure>
> +
> +<ch_title>View Results Tree</ch_title>
> +<p>Improve the ergonomics of View Results Tree by changing placement of Renderers and allowing custom ordering
> +(with the property <i>view.results.tree.renderers_order</i>).</p>
> +<figure width="900" height="329" image="changes/2.12/07_view_results_tree.png"></figure>
> +
> +<ch_title>Response Time Graph</ch_title>
> +<p>Adding the ability for the <b>Response Time Graph</b> listener to save/restore format its settings in/from the jmx file.</p>
> +<figure width="997" height="574" image="changes/2.12/08_response_time_graph.png"></figure>
> +
> +<ch_title>Log Viewer</ch_title>
> +<p>Starting with this version, the last lines of JMeter's log file (jmeter.log) can be viewed directly in GUI by clicking on Warning icon in the upper right corner.
> +This will unfold the Log Viewer panel and show logs.</p>
> +<figure width="1024" height="437" image="changes/2.12/11_log_viewer.png"></figure>

> +<li>
> +The numbers that appear to the left of the green box are the number of active threads / total number of threads,

> +<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>
> + [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>
> +java.util.prefs.WindowsPreferences
> +WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0
> +x80000002. Windows RegCreateKeyEx(...) 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 Java 1.6 and Gnome 3 on Linux systems, the JMeter menu may not work correctly (shift between mouse's click and the menu).
> +This is a known Java bug (see  <bugzilla>54477 </bugzilla>).
> +A workaround is to use a Java 7 runtime (OpenJDK or Oracle JDK).
> +</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.sun.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>
> +You may encounter the following error: <i>java.security.cert.CertificateException: Certificates does not conform to algorithm constraints</i>
> + 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></br>
> +To allow you to perform your HTTPS request, you can downgrade the security of your Java installation by editing
> +the Java <b>jdk.certpath.disabledAlgorithms</b> property. Remove the MD2 value or the constraint on size, depending on your case.
> +<br></br>
> +This property is in this file:

> +<ul>
> +<li>Since JMeter 2.12, active threads in all thread groups and active threads in current thread group are saved by default to CSV or XML results, see <bugzilla>57025</bugzilla>.
> +This is usually the expected behaviour as you want to have the number of running threads during the test. But if you want to revert to previous behaviour, set property <b>jmeter.save.saveservice.thread_counts=false</b></li>
> +<li>Since JMeter 2.12, Mail Reader Sampler will show 1 for number of samples instead of number of messages retrieved, see <bugzilla>56539</bugzilla></li>
> +<li>Since JMeter 2.12, when using Cache Manager, if resource is found in cache no SampleResult will be created, in previous version a SampleResult with empty content and 204 return code was returned, see <bugzilla>54778</bugzilla>.
> +You can choose between different ways to handle this case, see cache_manager.cached_resource_mode in jmeter.properties.</li>
> +<li>Since JMeter 2.12, Log Viewer will no more clear logs when closed and will have logs available even if closed. See <bugzilla>56920</bugzilla>. Read <a href="./usermanual/hints_and_tips.html#debug_logging">Hints and Tips &gt; Enabling Debug logging</a>
