</p>
<!-- =================== Known bugs =================== -->
<h2>Known bugs</h2>
<p>The Once Only controller behaves correctly under a Thread Group or Loop Controller,
but otherwise its behaviour is not consistent (or clearly specified).</p>
<p>Listeners don't show iteration counts when a If Controller has a condition which is always false from the first iteration (see <bugzilla>52496</bugzilla>).
A workaround is to add a sampler at the same level as (or superior to) the If Controller.
For example a Test Action sampler with 0 wait time (which doesn't generate a sample),
or a Debug Sampler with all fields set to False (to reduce the sample size).
</p>
<!-- =================== Incompatible changes =================== -->
<h2>Incompatible changes</h2>
<p>
When doing replacement of User Defined Variables, Proxy will not substitute partial values anymore when "Regexp matching" is used. It will use Perl 5 word matching ("\b")
</p>
<p>
In User Defined Variables, Test Plan, HTTP Sampler Arguments Table, Java Request Defaults, JMS Sampler and Publisher, LDAP Request Defaults and LDAP Extended Request Defaults, rows with
empty Name and Value are no more saved.
</p>
<p>
JMeter now expands the Test Plan tree to the testplan level and no further and selects the root of the tree. Furthermore default value of onload.expandtree is false.
</p>
<p>
Graph Full Results Listener has been removed.
</p>
<p>
When calling "Clear All" command, if Log Viewer is displayed its content will be cleared.
</p>

</p>
<h3>JMeter jars available from Maven repository</h3>
<p>
JMeter jars are now available from Maven repository.
</p>
<!-- =================== Known bugs =================== -->
<h2>Known bugs</h2>
<p>
The Include Controller has some problems in non-GUI mode (see Bugs 40671, 41286, 44973, 50898).
In particular, it can cause a NullPointerException if there are two include controllers with the same name.
</p>
<p>The Once Only controller behaves correctly under a Thread Group or Loop Controller,
but otherwise its behaviour is not consistent (or clearly specified).</p>
<p>Listeners don't show iteration counts when a If Controller has a condition which is always false from the first iteration (see <bugzilla>52496</bugzilla>).
A workaround is to add a sampler at the same level as (or superior to) the If Controller.
For example a Test Action sampler with 0 wait time (which doesn't generate a sample),
or a Debug Sampler with all fields set to False (to reduce the sample size).
</p>
<!-- =================== Incompatible changes =================== -->
<h2>Incompatible changes</h2>
<p>
JMeter versions since 2.1 failed to create a container sample when loading embedded resources.
This has been corrected; can still revert to the <bugzilla>51939</bugzilla> behaviour by setting the following property:
<code>httpsampler.separate.container=false</code>
</p>
<p>
Mirror server now uses default port 8081, was 8080 before 2.5.1.
</p>
<p>
TCP Sampler handles SocketTimeoutException, SocketException and InterruptedIOException differently since 2.6, when
these occurs, Sampler is marked as failed.
</p>
<p>
Sample Sender implementations now resolve their configuration on Client side since 2.6.
This behaviour can be changed with property sample_sender_client_configured (set it to false).
</p>
<p>
The HTTP User Parameter Modifier test element has been removed; it has been deprecated for a long time.
</p>

</ul>
<!-- ========== 2.5.1 =========== -->
<h1>Version 2.5.1</h1>
<h2>Summary of main changes</h2>
<ul>
<li>HttpClient4 sampler now re-uses connections properly (previously it would use one per sample, which could quickly cause resource exhaustion).</li>
<li>Various fixes to JMS samplers</li>
<li>Functions are no longer spuriously invoked when used with a Configuration element</li>
<li>WebService sampler GUI has been re-organized for better design and more user-friendliness. Some improments on WSDL configuration assistant</li>
<li>Better handling of test shutdown. System.exit now only called if there is no other option; even this can be disabled.</li>
</ul>
<h2>Known bugs</h2>
<p>
The Include Controller has some problems in non-GUI mode.
In particular, it can cause a NullPointerException if there are two include controllers with the same name.
</p>
<p>The Once Only controller behaves correctly under a Thread Group or Loop Controller,
but otherwise its behaviour is not consistent (or clearly specified).</p>
<p>The If Controller may cause an infinite loop if the condition is always false from the first iteration.
A workaround is to add a sampler at the same level as (or superior to) the If Controller.
For example a Test Action sampler with 0 wait time (which doesn't generate a sample),
or a Debug Sampler with all fields set to False (to reduce the sample size).
</p>
<p>
The menu item Options / Choose Language does not change all the displayed text to the new language.
[The behaviour has improved, but language change is still not fully working]
To override the default local language fully, set the JMeter property "language" before starting JMeter.
</p>
<h2>Incompatible changes</h2>
<p>
The HttpClient4 and Commons HttpClient 3.1 samplers previously used a retry count of 3.
This has been changed to default to 1, to be compatible with the Java implementation.
The retry count can be overridden by setting the relevant JMeter property, for example:
<pre>
httpclient4.retrycount=3
httpclient3.retrycount=3
</pre>
</p>

<!-- ========================= End of summary ===================================== -->
<h2>Known bugs</h2>
<p>
The Include Controller has some problems in non-GUI mode.
In particular, it can cause a NullPointerException if there are two include controllers with the same name.
</p>
<p>Once Only controller behaves correctly under a Thread Group or Loop Controller,
but otherwise its behaviour is not consistent (or clearly specified).</p>
<p>
The menu item Options / Choose Language does not change all the displayed text to the new language.
[The behaviour has improved, but language change is still not fully working]
To override the default local language fully, set the JMeter property "language" before starting JMeter.
</p>
<h2>Incompatible changes</h2>
<p>
Unsupported methods are no longer converted to GET by the Commons HttpClient sampler.
</p>
<p>
Removed method public static long currentTimeInMs().
This has been replaced by the instance method public long currentTimeInMillis().
</p>
<p>
ProxyControl.getSamplerTypeName() now returns a String rather than an int.
This is internal to the workings of the JMeter Proxy &amp; its GUI, so should not affect any user code.

<li>Many other improvements have been made, please see below and in the manual.</li>
</ul>
</p>
<!-- ========================= End of summary ===================================== -->
<h2>Known bugs</h2>
<p>
The Include Controller has some problems in non-GUI mode.
In particular, it can cause a NullPointerException if there are two include controllers with the same name.
</p>
<p>Once Only controller behaves correctly under a Thread Group or Loop Controller,
but otherwise its behaviour is not consistent (or clearly specified).</p>
<p>
The menu item Options / Choose Language does not change all the displayed text to the new language.
[The behaviour has improved, but language change is still not fully working]
To override the default local language fully, set the JMeter property "language" before starting JMeter.
</p>
<h2>Incompatible changes</h2>
<p>
HTTP Redirect now defaults to "Follow Redirects" rather than "Redirect Automatically".
This is to enable JMeter to track cookies that may be sent during redirects.
This does not affect existing test plans; it only affects the default for new HTTP Samplers.
</p>
<p>
The Avalon file format for JMX and JTL files is no longer supported.
Any such files will need to be converted by reading them in JMeter 2.3.4 and resaving them.
</p>
<p>
The XPath Assertion and XPath Extractor elements no longer fetch external DTDs by default; this can be changed in the GUI.
</p>
<p>
JMSConfigGui has been renamed as JMSSamplerGui.
This does not affect existing test plans.
</p>
<p>
The constructor public SampleResult(SampleResult res) has been changed to become a true "copy constructor".
It no longer calls addSubResult(). This may possibly affect some 3rd party add-ons.
</p>

<ul>
<li><bugzilla>47266</bugzilla> - FTP Request Sampler: allow specifying an FTP port, other than the default</li>
</ul>
<!-- =================== -->
<h1>Version 2.3.3</h1>
<h2>Summary of main changes</h2>
<p>
The handling of test closedown is much improved.
The gradual "Shutdown" command now waits until all threads have stopped,
and does not report an error if threads don't stop within 5 seconds.
The immediate "Stop" command can now be used if "Shutdown" takes too long.
Also the immediate "Stop" command is able to interrupt samplers which support the new Interruptible interface (e.g. HTTP and SOAP, FTP).
This allows immediate completion of pending responses.
Non-GUI mode tests can also now be sent a "Shutdown" or "Stop" message.
<complink name="Test Action"/> now supports a "Stop Now" action,
as do the <complink name="Thread Group"/> and <complink name="Result Status Action Handler"/> Post Processor elements.
</p>
<p>
HTTP Cookie handling is improved, and HTTP POST can now use variable file names correctly.
HTTP, SOAP/XML-RPC and WebService(SOAP) sampler character encodings updated to be more consistent.
HTTP Samplers now support connection and response timeouts (requires JVM 1.5 for the HTTP Java sampler).
Together with the closedown improvements described above, this should avoid most cases where a test run hangs.
Multiple Header Manager elements are now supported for a single HTTP sampler.
The Proxy Server is improved, and no longer stores "Host" headers by default.
</p>
<p>
JDBC Request can optionally save the results of Select statements to variables.
JDBC Request now handles quoted strings and UTF-8, and can handle arbitrary variable types.
</p>
<p>
There are several new <a href="usermanual/functions.html">functions</a>:
__char() function: allows arbitrary Unicode characters to be entered in fields.
__unescape() function: allows Java-escaped strings to be used.
_unescapeHtml() function: decodes Html-encoded text.
__escapeHtml() function: encodes text using Html-encoding.
A reference to a missing function - e.g. ${__missing(a)} - is now treated the same as a missing variable.
Previously the function name - and leading { - were dropped. This makes it easier to debug test plans.
</p>
<p>
Some Assertions can now be applied to sub-samples as well as (or instead of) just the parent sample.
There is a new <complink name="Random Variable"/> Configuration element.
</p>
<p>
JMS samplers are much improved (see details below). The <complink name="TCP Sampler"/> now supports some additional clients and is a bit more flexible.
</p>
<p>
Client-server mode has been improved, and the server can optionally use a fixed RMI port, which should help with setting up firewalls.
</p>
<p>
Various I18N changes have been made; language change works better (though not perfect yet).
There are improved French translations as well as new Polish and Brazilian Portugese translations.
</p>
<p>
The BeanShell jar is now included with the binary archive; there is no need to download it separately.
</p>
<!-- ========================= End of summary ===================================== -->
<h2>Known bugs</h2>
<p>
The Include Controller has some problems in non-GUI mode.
In particular, it can cause a NullPointerException if there are two include controllers with the same name.
</p>
<p>Once Only controller behaves correctly under a Thread Group or Loop Controller,
but otherwise its behaviour is not consistent (or clearly specified).</p>
<p>
The menu item Options / Choose Language does not change all the displayed text to the new language.
[The behaviour has improved, but language change is still not fully working]
To override the default local language fully, set the JMeter property "language" before starting JMeter.
</p>
<h2>Incompatible changes</h2>
<p>
When loading sample results from a file, previous results are no longer cleared.
This allows one to merge multiple files.
If the previous behaviour is required,
use the menu item Run/Clear (Ctrl+Shift+E) or Run/Clear All (Ctrl+E) before loading the file.
</p>
<p>
The test elements "Save Results to a file" and "Generate Summary Results" are now shown as Listeners.
They were previously shown as Post-Processors, even though they are implemented as Listeners.
</p>
<p>
The Cookie Manager no longer saves incoming cookies as variables by default.
To save cookies as variables, define the property "CookieManager.save.cookies=true".
Also, cookies names are prefixed with "COOKIE_" before they are stored (this avoids accidental corruption of local variables)
To revert to the original behaviour, define the property "CookieManager.name.prefix= " (one or more spaces).
</p>
<p>
The Counter element is now shown as a Configuration element.
It was previously shown as a Pre-Processor, even though it is implemented as a Config item.
</p>
<p>
The above changes only affect the icons that are displayed and the locations in the GUI pop-up menus.
They do not affect test plans or test behaviour.
</p>
<p>
The PreProcessors are now invoked directly by the JMeterThread class,
rather than by the TestCompiler#configureSampler() method. (JMeterThread handles the PostProcessors).
This does not affect test plans or behaviour, but could perhaps affect 3rd party add-ons (very unlikely).
</p>
<p>
Moved the Scoping Rules sub-section from Section 3. "Building a Test Plan" to Section 4. "Elements of a test plan"
</p>
<p>
The While controller now trims leading and trailing spaces from the condition value before it is compared
with LAST, blank or false.
</p>
<p>
The "threadName" variable in the _jexl() and __javaScript() functions was previously misspelt as "theadName".
</p>
<p>
The following deprecated methods were removed from JOrphanUtils: booleanToString(boolean) and valueOf(boolean).
Java 1.4+ has these methods in the Boolean class.
</p>
<p>
The TestElement interface has some new methods:
<ul>
<li>void setProperty(String key, String value, String dflt)</li>
<li>void setProperty(String key, boolean value, boolean dflt)</li>
<li>void setProperty(String key, int value)</li>
<li>void setProperty(String key, int value, int dflt)</li>
<li>int getPropertyAsInt(String key, int defaultValue)</li>
</ul>
These are implemented in the AbstractTestElement class which all elements should extend so this is unlikely to cause a problem.
</p>

<!-- =================== -->
<h2>Version 2.3.2</h2>
<h3>Summary of main changes</h3>
<h4>Bug fixes</h4>
<p>
Version 2.3.1 changed the way binary and text content types were determined as far as the View Results Tree Listener was concerned:
originally everything except "image/" content types were considered text, but 2.3.1 introduced a check
for specific content types. This has caused problems,
as several popular types were omitted and these were no longer shown by default in the Response tab.
Rather than try to list all the possible text types, JMeter now just checks for the following binary types:
<ul>
<li>image/*</li>
<li>audio/*</li>
<li>video/*</li>
</ul>
All other types are now assumed to be text.
</p>
<p>
JMeter 2.3.1 introduced a bug in the Cookie Manager
- if "Clear Cookie each iteration" was selected, all threads would see the same cookies.
This bug has been corrected.
</p>
<h4>Improvements</h4>
<p>
The Proxy server can now record binary requests.
By default the content types
application/x-amf and application/x-java-serialized-object
will be treated as binary and saved in a file.
To change the content types, update the property <b>proxy.binary.types</b>.
</p>
<p>
The CSV Dataset configuration element has new file sharing options: per thread group, per thread, per identifier.
This allows for more flexible file processing, e.g. each thread can process the same data in the same order.
</p>
<p>Switch Controller now works properly with functions and variables,
and the condition can now be a name instead of a number.
Simple Controller now works properly under a While Controller</p>
<p>CSV fields in JTL files can now contain delimiters.
CSV and XML files can now contain additional variables (define the JMeter property <b>sample_variables</b>).</p>
<p>Response Assertion can now match on substrings (i.e. not regular expression).
Regex extractor can operate on variables.</p>
<p>
XPath processing is improved; Tidy errors are handled better.
</p>
<p>Save Table Data buttons added to Summary and Aggregate reports to allow easy saving of the calculated data.</p>
<p>
HTTP samplers can now save just the MD5 hash of responses, rather than the entire response.
As a special case, if the HTTP Sampler path starts with "http://" or "https://" then this is used as the full URL,
overriding the host and port fields.
The HTTP Samplers can now POST multiple files.
Webservice(SOAP) Sampler can now load local WSDL files using the "file:" protocol.
</p>
<p>
A simple HTTP Cache Manager has been added. This needs further development.
</p>
<p>
View Results Tree Listener now uses Tidy to display XML.
This should allow more content to be displayed succesfully.
It also avoids the need to download remote DTD files, which can slow the rendering considerably.
</p>
<p>
MailReader sampler now supports POP3S and IMAPS protocols. Individual mails are now added as sub-samples.
</p>
<p>
Various improvements to the BSF Sampler: now supports Jexl, and Javascript bug works properly.
Added BSF PreProcessor, PostProcessor and Assertion test elements.
All now have access to "props" JMeter Properties object.
</p>
<p>Number of classes loaded in non-GUI mode is much reduced.</p>
<h3>Known bugs</h3>
<p>
The Include Controller has some problems in non-GUI mode.
In particular, it can cause a NullPointerException if there are two include controllers with the same name.
</p>
<p>Once Only controller behaves OK under a Thread Group or Loop Controller,
but otherwise its behaviour is not consistent (or clearly specified).</p>
<p>
The menu item Options / Choose Language does not change all the displayed text to the new language.
To override the default local language, set the JMeter property "language" before starting JMeter.
</p>
<h3>Incompatible changes</h3>
<ul>
<li>
To reduce the number of classes loaded in non-GUI mode,
Functions will only be found if their classname contains the string
'.functions.' and does not contain the string '.gui.'.
All existing JMeter functions conform to this restriction.
To revert to earlier behaviour, comment or change the properties classfinder.functions.* in jmeter.properties.
</li>
<li>The reference value parameter for intSum() is now optional.
As a consequence, if a variable name is used, it must not be a valid integer.</li>
<li>The supplied TCPClient implementation no longer treats tcp.eolByte=0 as special.
To skip EOL checking, set tcp.eolByte=1000 (or some other value which is not a valid byte)
</li>
<li>
Leading and trailing spaces are trimmed from variable names in function calls.
For example, ${__Random(1,63, LOTTERY )} will use the variable 'LOTTERY' rather than ' LOTTERY '.
</li>
<li>
Synchronization has been removed from the RunningSample class (it was not fully threadsafe anyway).
Developers of 3rd party add-ons that use the class may need to synchronize access.
</li>
</ul>

<!-- =================== -->
<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 <bugzilla>43168</bugzilla>.
</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 <bugzilla>39337</bugzilla>.
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>
<bugzilla>22510</bugzilla> - 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 <bugzilla>40394</bugzilla>)
</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>
<bugzilla>41140</bugzilla>: 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>

<h3>Version 2.0.1</h3>
<p>Bug fix release. TBA.</p>
<h3>Version 2.0</h3>
<ul>
<li>HTML parsing improved; now has choice of 3 parsers, and most embedded elements can now be detected and downloaded.</li>
<li>Redirects can now be delegated to URLConnection by defining the JMeter property HTTPSamper.delegateRedirects=true (default is false) </li>
<li>Stop Thread and Stop Test methods added for Samplers and Assertions etc. Samplers can call setStopThread(true) or setStopTest(true) if they detect an error that needs to stop the thread of the test after the sample has been processed </li>
<li>Thread Group Gui now has an extra pane to specify what happens after a Sampler error: Continue (as now), Stop Thread or Stop Test.
This needs to be extended to a lower level at some stage. </li>
<li>Added Shutdown to Run Menu. This is the same as Stop except that it lets the Threads finish normally (i.e. after the next sample has been completed) </li>
<li>Remote samples can be cached until the end of a test by defining the property hold_samples=true when running the server.
More work is needed to be able to control this from the GUI </li>
<li>Proxy server has option to skip recording browser headers </li>
<li>Proxy restart works better (stop waits for daemon to finish) </li>
<li>Scheduler ignores start if it has already passed </li>
<li>Scheduler now has delay function </li>
<li>added Summariser test element (mainly for non-GUI) testing. This prints summary statistics to System.out and/or the log file every so oftem (3 minutes by default). Multiple summarisers can be used; samples are accumulated by summariser name. </li>
<li>Extra Proxy Server options:
Create all samplers with keep-alive disabled
Add Separator markers between sets of samples
Add Response Assertion to first sampler in each set </li>
<li>Test Plan has a comment field</li>
<li>Help Page can now be pushed to background</li>
<li>Separate Function help page</li>
<li>New / amended functions</li>

<h3>Version 1.5</h3>
<ul>
<li>Abstracted out the concept of the Sampler, SamplerController, and TestSample.
A Sampler represents code that understands a protocol (such as HTTP,
or FTP, RMI, SMTP, etc..). It is the code that actually makes the
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>
<li>....and many more minor changes/improvements...</li>
