<h3>
Version 2.2
</h3>
<h4>
Incompatible changes:
</h4>
<p>

The time stamp is now set to the sampler start time (it was the end).
To revert to the previous behaviour, change the property 
<b>
sampleresult.timestamp.start
</b>
 to false (or comment it)

</p>
<p>
The JMX output format has been simplified and files are not backwards compatible
</p>
<p>

The JMeter.BAT file no longer changes directory to JMeter home, but runs from the current working directory.
The jmeter-n.bat and jmeter-t.bat files change to the directory containing the input file.

</p>
<p>

Listeners are now started slightly later in order to allow variable names to be used.
This may cause some problems; if so define the following in jmeter.properties:

<br>
</br>

jmeterengine.startlistenerslater=false

</p>
<p>

The GUI now expands the tree by default when loading a test plan.
This can be disabled by setting the JMeter property 
<b>
onload.expandtree=false
</b>


</p>
<h4>
Known problems:
</h4>
<ul>


<li>
Post-processors run in reverse order (see bug 41140)
</li>


<li>
Module Controller does not work in non-GUI mode
</li>


<li>

<li>

</li>


<li>

this can cause memory exhaustion in long-running tests

</li>


</ul>
