+<!-- =================== -->
+
+<h3>Version 2.3.1</h3>
+<h4>Summary of changes</h4>
+
+<h5>JMeter Proxy</h5>
+
+<p>
+The Proxy spoof function was broken in 2.3; it has been fixed.
+Spoof now supports an optional parameter to limit spoofing to particular URLs.
+This is useful for HTTPS pages that have insecure content - e.g. images/stylesheets may be accessed using HTTP.
+Spoofed responses now drop the default port (443) from https links to make them work better.
+</p>
+<p>
+Ignored proxy samples are now visible in Listeners - the label is enclosed in [ and ] as an indication.
+Proxy documentation has been improved.
+</p>
+
+<h5>GUI changes</h5>
+
+<p>The Add menus show element types in the order in which they are processed
+- see <a href="usermanual/test_plan.html#executionorder">Test Plan Execution Order</a>.
+It is no longer possible to add test elements to inappropriate parts of the tree
+- e.g. samplers cannot be added directly under a test plan.
+This also applies to Paste and drag and drop.
+</p>
+
+<p>
+The File menu now supports a "Revert" option, which reloads the current file.
+Also the last few file names used are remembered for easy reloading.
+</p>
+
+<p>
+The Options Menu now supports Collapse All and Expand All items to collapse and expand the test tree.
+</p>
+
+<h5>Remote testing</h5>
+
+<p>
+The JMeter server now starts the RMI server directly (by default).
+This simplifies testing, and means that the RMI server will be stopped when the server stops.
+</p>
+
+<p>
+Functions can now be used in Listener filenames (variables do not work).
+</p>
+
+<p>
+Command-line option -G can now be used to define properties for remote servers.
+Option -X can be used to stop a remote server after a non-GUI run.
+Server can be set to automatically exit after a single test (set property server.exitaftertest=true).
+</p>
+
+<h5>Other enhancements</h5>
+
+<p>
+JMeter startup no longer loads as many classes; this should reduce memory requirements.
+</p>
+
+<p>
+Parameter and file support added to all BeanShell elements.
+Javascript function now supports access to JMeter objects;
+Jexl function always did have access, but the documentation has now been included.
+New functions __eval() and __evalVar() for evaluating variables.
+</p>
+
+<p>
+CSV files with the correct header column names are now automatically recognised when loaded.
+There is no need to configure the properties.
+</p>
+
+<p>
+The hostname can now be saved in CSV and XML output files.
+New "Successes only" option added when saving result files.
+Errors / Successes only option is now supported when loading XML and CSV files.
+</p>
+
+<p>
+General documentation improvements.
+</p>
+
+<h5>HTTP</h5>
+
+<p>PUT and DELETE should now work properly.
+Cookie Manager no longer clears manually entered cookies.
+</p>
+<p>Now handles the META tag http-equiv charset</p>
+
+<h5>JDBC</h5>
+
+<p>JDBC Sampler now allows INOUT and OUT parameters for Called procedures.
+JDBC Sampler now allows per-thread connections - set Max Connections = 0 in JDBC Config.
+</p>
+
+<hr></hr>
+<!-- ========================================================= -->
+
+<h4>Incompatible changes</h4>
+<ul>
+<li>JMeter server now creates the RMI registry by default.
+If the RMI registry has already been started externally, this will generate a warning message, but the server will continue.
+This should not affect JMeter testing.
+However, if you are also using the RMI registry for other applications there may be problems.
+For example, when the JMeter server shuts down it will stop the RMI registry.
+Also user-written command files may need to be adjusted (the ones supplied with JMeter have been updated).
+To revert to the earlier behaviour, define the JMeter property: <b>server.rmi.create=false</b>.
+</li>
+<li>The Proxy server removes If-Modified-Since and If-None-Match headers from generated Header Managers.
+To revert to the previous behaviour, define the property proxy.headers.remove with no value</li>
+</ul>

+
+<h3>Version 2.3RC3</h3>
+
+<h4>Known problems/restrictions:</h4>
+<p>
+The JMeter remote server does not support multiple concurrent tests - each remote test should be run in a separate server.
+Otherwise tests may fail with random Exceptions, e.g. ConcurrentModification Exception in StandardJMeterEngine.
+See bug 43168.
+</p>
+<p>
+The default HTTP Request (not HTTPClient) sampler may not work for HTTPS connections via a proxy.
+This appears to be due to a Java bug, see <a href="http://issues.apache.org/bugzilla/show_bug.cgi?id=39337">Bug 39337</a>.
+To avoid the problem, try a more recent version of Java, or switch to the HTTPClient version of the HTTP Request sampler.
+</p>
+<p>Transaction Controller parent mode does not support nested Transaction Controllers.
+Doing so may cause a Null Pointer Exception in TestCompiler.
+</p>
+<p>Thread active counts are always zero in CSV and XML files when running remote tests.
+</p>
+<p>The property file_format.testlog=2.1 is treated the same as 2.2.
+However JMeter does honour the 3 testplan versions.</p>
+<p>
+Bug 22510 - JMeter always uses the first entry in the keystore.
+</p>
+<p>
+Remote mode does not work if JMeter is installed in a directory where the path name contains spaces.
+</p>
+<p>
+BeanShell test elements leak memory.
+This can be reduced by using a file instead of including the script in the test element.
+</p>
+<p>
+Variables and functions do not work in Listeners in client-server (remote) mode so they cannot be used
+to name log files in client-server mode.
+</p>
+<p>
+CSV Dataset variables are defined after configuration processing is completed,
+so they cannot be used for other configuration items such as JDBC Config.
+(see <a href="http://issues.apache.org/bugzilla/show_bug.cgi?id=40934">Bug 40394 </a>)
+</p>
+
+<h4>Summary of changes (for more details, see below)</h4>
+<p>
+Some of the main enhancements are:
+</p>
+<ul>
+<li>Htmlparser 2.0 now used for parsing</li>
+<li>HTTP Authorisation now supports domain and realm</li>
+<li>HttpClient options can be specified via httpclient.parameters file</li>
+<li>HttpClient now behaves the same as Java Http for SSL certificates</li>
+<li>HTTP Mirror Server to allow local testing of HTTP samplers</li>
+<li>HTTP Proxy supports XML-RPC recording, and other proxy improvements</li>
+<li>__V() function allows support of nested variable references</li>
+<li>LDAP Ext sampler optionally parses result sets and supports secure mode</li>
+<li>FTP Sampler supports Ascii/Binary mode and upload</li>
+<li>Transaction Controller now optionally generates a Sample with subresults</li>
+<li>HTTPS session contexts are now per-thread, rather than shared. This gives better emulation of multiple users</li>
+<li>BeanShell elements now support ThreadListener and TestListener interfaces</li>
+<li>Coloured icons in Tree View Listener and elsewhere to better differentiate failed samples.</li>
+</ul>
+<p>
+The main bug fixes are:
+</p>
+<ul>
+<li>HTTPS (SSL) handling now much improved</li>
+<li>Various Remote mode bugs fixed</li>
+<li>Control+C and Control+V now work in the test tree</li>
+<li>Latency and Encoding now available in CSV log output</li>
+<li>Test elements no longer default to previous contents; test elements no longer cleared when changing language.</li>
+</ul>
+
+<h4>Incompatible changes (usage):</h4>
+<p>
+<b>N.B. The javax.net.ssl properties have been moved from jmeter.properties to system.properties,
+and will no longer work if defined in jmeter.properties.</b>
+<br></br>
+The new arrangement is more flexible, as it allows arbitrary system properties to be defined.
+</p>
+<p>
+SSL session contexts are now created per-thread, rather than being shared.
+This generates a more realistic load for HTTPS tests.
+The change is likely to slow down tests with many SSL threads.
+The original behaviour can be enabled by setting the JMeter property:
+<pre>
+https.sessioncontext.shared=true
+</pre>
+</p>
+<p>
+The LDAP Extended Sampler now uses the same panel for both Thread Bind and Single-Bind tests.
+This means that any tests using the Single-bind test will need to be updated to set the username and password.
+</p>
+<p>
+Bug 41140: JMeterThread behaviour was changed so that PostProcessors are run in forward order
+(as they appear in the test plan) rather than reverse order as previously.
+The original behaviour can be restored by setting the following JMeter property:
+<br/>
+jmeterthread.reversePostProcessors=true
+</p>
+<p>
+The HTTP Authorisation Manager now has extra columns for domain and realm,
+so the temporary work-round of using '\' and '@' in the username to delimit the domain and realm
+has been removed.
+</p>
+<p>
+Control-Z no longer used for Remote Start All - this now uses Control+Shift+R
+</p>
+<p>
+HttpClient now uses pre-emptive authentication.
+This can be changed by setting the following:
+<pre>
+jmeter.properties:
+httpclient.parameters.file=httpclient.parameters
+
+httpclient.parameters:
+http.authentication.preemptive$Boolean=false
+</pre>
+</p>
+
+<p>
+The port field in HTTP Request Defaults is no longer ignored for https samplers if it is set to 80.
+</p>
+
+<h4>Incompatible changes (development):</h4>
+<p>
+<b>N.B.</b>The clear() method was defined in the following interfaces: Clearable, JMeterGUIComponent and TestElement.
+The methods serve different purposes, so two of them were renamed:
+the Clearable method is now clearData() and the JMeterGUIComponent method is now clearGui().
+3rd party add-ons may need to be rebuilt.
+</p>
+<p>
+Calulator and SamplingStatCalculator classes no longer provide any formatting of their data.
+Formatting should now be done using the jorphan.gui Renderer classes.
+</p>
+<p>
+Removed deprecated method JMeterUtils.split() - use JOrphanUtils version instead.
+</p>
+<p>
+Removed method saveUsingJPEGEncoder() from SaveGraphicsService.
+It was unused so far, and used the only Sun-specific class in JMeter.
+</p>

+<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/>
+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>

+ connection to whatever is being tested. A SamplerController
+ represents code that understands how to organize and run a group
+ of test samples. It is what binds together a Sampler and its test
+ samples and runs them. A TestSample represents code that understands
+ how to gather information from the user about a particular test.
+ For a website, it would represent a URL and any information to be sent
+ with the URL.</li>
+ <li>The UI has been updated to make entering test samples more convenient.</li>
+ <li>Thread groups have been added, allowing a user to setup multiple test to run
+ concurrently, and to allow sharing of test samples between those tests.</li>
+ <li>It is now possible to save and load test samples.</li>
