General:
Issue#6043, PR#6044 – JMeter 5.6 shows 0 as a min response time in summary report
Restored binary API compatibility with pre-5.6.2: restore public methods to non-static as they were before 5.6.2 JavaSamplerContext.getJMeterVariables, JavaSamplerContext.getJMeterProperties, BoundaryExtractor.extractAll, AuthManager.setupCredentials, HttpRequestHdr.getMultipartConfig, (regression since 5.6.2)
Issue#6165, PR#6192 – The Constant Throughput Timer is throwing a NullPointerException when using variables (vars.get) in "Target Throughput"-field
Issue#6162 – The Constant Timer is throwing a NullPointerException when using variables (vars.get) in "delay"-field
PR#6193 – Log errors happening while JMeter starts the test (previously, errors from TestStateListener.testStarted were not logged)
PR#6216 – Pass JDBCSampler.maxRows to Statement.setMaxRows so the driver does not fetch extra rows from the database
Non-functional changes:

New in Apache JMeter 5.5 (Jun 16, 2022)

New and Noteworthy:
JMeter now supports Java 17
JMeter 5.5 ships with log4j2 2.17.2
Open Model Thread Group:
New component: Open Model Thread Group allows creating load profiles with variable load.
For example, if you need to gradually increase load from 0/sec to 10/sec during minute you could previously use Thread Group + Timer combinations. However, then you need to compute the expected number of threads, ensure they are created only when needed, and so on.
With Open Model Thread Group you can configure the same load profile as rate(0/sec) random_arrivals(1 minute) rate(10/sec). The thread group would spawn threads as needed to drive the configured load. The load profile can use properties, so you can launch the same script with slightly different load levels, however, the profile can't be updated while the test is running.
The new thread group is experimental in JMeter 5.5, so please feel free to submit your feedback.
Preparing the deprecation of Oro Regex usage:
Another experimental feature in JMeter 5.5 is the ability to replace the Oro based Regex implementation by the built-in Java based one. To choose the Java based one, set the JMeter property jmeter.regex.engine to the value java.
Core improvements:
Kotlin language is now used in some core classes and tests (e.g. Open Model Thread Group). JMeter is compiled with apiTarget=1.5, and it ships with kotlin-stdlib 1.6.
lets-plot-kotlin charting library is added, so it will be easier to refine and create new charts in UI in the future.
Improvements:
Thread Groups:
New component: Open Model Thread Group

Incompatible changes:
Remove LogKit logger functionality from some classes. This was intended to completely remove LoggingManager class (it has been deprecated since JMeter 3.2), but as jmeter-plugins depended on it, LoggingManager and our LogKit-adapter will remain for this version (but is still deprecated).

Bug 58183 - Rampup may not be respected if thread take time to start leading to threads continuing to start post ramp up time

New in Apache JMeter 5.1 (Feb 21, 2019)

New and Noteworthy:
Core improvements:
JDBC testing has been improved with ability to set init SQL statements and add compatibility with JDBC drivers that do not support QueryTimeout
Various bug fixes have been implemented, like gathering the correct headers when recording requests through the HTTP(S) Test Script Recorder using HTTPS
In version 5.0, JMeter was changed to rename Sub results using a custom Naming Policy ( Bug 62550). This change could be annoying for Functional Testing, a new property subresults.disable_renaming=true has been introduced to revert if needed to previous behaviour. An alternative is to check Functional Test Mode in Test Plan, see Bug 63055
UX improvements:
Templates can provide parameters that are filled in on test plan generation, Recording template uses this feature
A new Tools menu has been introduced to collect those entries, that are used for general usage around JMeter, like:
Function Helper Dialog
Export transactions for report
Generate Schematic View which provides an overview as HTML of the Test plan
Import from cURL which allows you to create or update your test plan by importing a cURL command
Compile JSR223 Test Elements
Create a heap dump
Create a thread dump
Test Plan:
Ability to create a Test plan from a cURL command.
Scripting / Debugging enhancements:
A menu item to compile all JSR223 Elements is now available in Tools menu
Live Reporting and Web Report:
A JSON file containing summary of a load test statistics is now generated when using -e or -g options.
Percentiles computing graphed over time algorithm has been modified to restart for each time slot
More user-friendly behaviour when reporting folder does not exist or is not empty through -f commmand line option
Incompatible changes:
In Response Time Percentiles Over Time (successful responses) graph of the HTML report, before this version, percentile computation of each time slot used the percentile data of previous time slot as a base. Starting with this version, each time slot is independant. See Bug 62883
ClientJMeterEngine#rsetProperties signature has been changed to use HashMap instead of Properties, see Bug 63034
A new Menu item Tools has been introduced, some menu items that were in Help menu are now under this new menu item. See Bug 63094
slf4j-ext has been removed from libraries (lib folder) and JMeter pom. It was not used by default and due to CVE-2018-8088 and unavailability of a stable version containing a fix to this issue, we decided to remove it. If you still needed, you can add it in lib folder.
Improvements:
HTTP Samplers and Test Script Recorder:
Bug 62840 - HTTP Request: Add option httpclient4.gzip_relax_mode to avoid error when unzipping what seems to be invalid streams
Bug 63025 - Enhance Search & Replace functionality for HTTP Request to include port and protocol field. Initial code fix by Mohamed Ibrahim (rollno748 at gmail.com)
Other samplers:
Bug 62934 - Add compatibility for JDBC drivers that do not support QueryTimeout
Bug 62935 - Pass custom mail.* properties to Mail Reader Sampler. Implemented by Artem Fedorov (artem.fedorov at blazemeter.com) and contributed by BlazeMeter.
Bug 63055 - Don't rename SampleResult Label when test is running in Functional mode or property subresults.disable_renaming=true. Implemented by Artem Fedorov (artem.fedorov at blazemeter.com) and contributed by BlazeMeter.

New in Apache JMeter 5.0 (Sep 19, 2018)

New and Noteworthy:
Core improvements:
Rest support has been improved in many fields:
Multipart/form-data requests now work for PUT, DELETE …
It is now also possible to send a JSON Body with attached file
Parameters entered in Parameters Tab are now used in body instead of being ignored
In distributed testing, JMeter now automatically prefixes thread names with engine host and port, this makes the counting of threads correct in the HTML report without any other configuration as it was required before
XPath 2.0 is supported in a new element called XPath2 extractor providing easier XML namespaces handling, up to date XPath syntax and better performances
Upgrade to HTTP Components 4.6 last APIs has been completed and JMeter does not rely anymore on deprecated APIs of this library
It is now possible to control in an easier way Loop breaking and Loop switching to next iteration. This is available in Flow Control Action and Result Status Action Handler elements
While Controller now exports a variable containing its current index named __jm____idx. So for example, if your While Controller is named WC, then you can access the looping index through ${__jm__WC__idx}
Scripting / Debugging enhancements:
Search feature has been improved to allow you to iterate in the tree over search results and do necessary replacements through Next/Previous/Replace/Replace/Find buttons
In View Results Tree, the request and response headers/body are clearly separated to allow you to better inspect requests and responses. You can also search in all those tabs for a particular value
Recording feature has been improved to provide a popup that is always on top when you navigate in browser allowing you to name transactions while you navigate in your application.
You can now restart JMeter from menu File → Restart
Live Reporting and Web Report:
Reporting feature has been enhanced
A new Graph Total Transactions per second has been added to the HTML Web Report
It is now possible to graph over time custom metrics available as JMeter Variables through sample_variables. Those custom metrics graphs will be available in the HTML Report in Custom Graphs section
Hits per second graph now takes into account the embedded resources
In Live reporting, the sent and received bytes are now sent to Backends (InfluxDB or Graphite)
Functions:
A New function __threadGroupName has been introduced to obtain ThreadGroup name.
Incompatible changes:
Since JMeter 5.0, when using default HC4 Implementation, JMeter will reset HTTP state (SSL State + Connections) on each thread group iteration. If you don't want this behaviour, set httpclient.reset_state_on_thread_group_iteration=false
Since JMeter 5.0, in relation to above remark, https.use.cached.ssl.context is deprecated and not used anymore.
Since JMeter 5.0, when using CSV output, sub results will now be also output to CSV file. To revert to previous behaviour set jmeter.save.saveservice.subresults=false, see Bug 62470, Bug 60917, Bug 62550.
Since JMeter 5.0, CSS/JQuery Extractor has been renamed to CSS Selector Extractor
Since JMeter 5.0, Test Action has been renamed to Flow Control Action

New in Apache JMeter 4.0 (Feb 11, 2018)

New in Apache JMeter 3.3 (Dec 11, 2017)

Core improvements:
HTTP Sampler now supports Brotli decompression.
CacheManager now completely supports Vary header.
InfluxDB BackendListener now supports sending results to InfluxDB through UDP protocol.
It has also been enhanced to send number of errors by response code and message for each transaction.
TCP Sampler now computes latency.
Upgraded dependencies to last available versions bringing performance improvements and bug fixes.
Continued to improve the quality of our code and tests coverage.
UX improvements:
More work has been done to better support HiDPI.
Some bugs, that crept in with the work on lowering the memory usage of View Results Tree, were fixed.
The constant DEFAULT_IMPLEMENTATION was removed from CookieManager, as it lost it purpose with the removal of the alternate HTTP Client implementation in the last release.
JDBC Sampler UX has been improved by adding select boxes for drivers and validation queries.
If Controller and While Controller UX have been improved.
Report/Dashboard improvements:
A new Help menu item has been added to simplify configuration of report generation.
Documentation improvements:
Incorporated feedback about unclear documentation.
Functions:
Function Helper Dialog: a new field that shows execution result has been added.
New functions:
__timeShift - return a date in various formats with the specified amount of seconds/minutes/hours/days added.
__RandomDate - generate random date within a specific date range.
Incompatible changes:
In InfluxDbBackendListenerClient, statut property has been renamed to status
In CookieManager, DEFAULT_POLICY and DEFAULT_IMPLEMENTATION constants are now private.
If you're using ignorecookies with HC3CookieHandler (< JMeter 3.1) configuration will be reset, ensure you put it back.
JMeter will not truncate anymore by default responses exceeding 10 MB. If you want to enable this truncation, see property httpsampler.max_bytes_to_store_per_request
org.apache.jmeter.protocol.tcp.sampler.TCPClient.read(InputStream) has been deprecated in favor or org.apache.jmeter.protocol.tcp.sampler.TCPClient.read(InputStream, SampleResult), ensure you update your implementation to be able to compute latency, see Bug 60156
Removed elements or functions:
_StringFromFile function has been dropped, use __StringFromFile instead

New in Apache JMeter 3.0 (May 18, 2016)

New and Noteworthy:
Test plan creation and debugging improvements
New Search Feature in View Results Tree to allow searching for text / regexp in Request/Responses/Headers/Cookies/… This will ease correlation and Test plans creation
New JSON Post Processor to better extract data from JSON content using user friendly JSON-PATH syntax
JSON is now a first class citizen in JMeter with the introduction of a new JSONPath post processor. This post processor is very similar to Regular Expression Post Processor but is well suited for JSON code. It is based on Jayway JSON Path library
New validation feature, in one click run a selection of Thread Groups with 1 user, no pause and 1 iteration
JSR223 Test Elements do not require a Cache Compilation Key anymore
Just check Cache compiled script if available checkbox and the elements (Pre-Processor, Post-Processor, Assertions, Listeners, …) will pre-compile the script and cache the compiled code if the underlying language supports it
Nashorn can now be used as Javascript engine providing better performance and easier usage
To enable Nashorn, you need to set in user.properties:
Nashorn can be used with Java 8 in the following elements:
IfController
JSR223 Test elements with javascript language selected
__javaScript function
Jexl3 has been integrated. It provides new scripting features and much better documentation
JEXL3 can now be used thanks to a new function __jexl3. JEXL is a language very similar to JSTL.
Simplified HTTP Request UI:
A new "Advanced" tab has been added to HTTP Request to simplify configuration. The file upload feature has been moved into a dedicated tab. This increases the space available for parameters in UI and simplifies the UX.
HTTP Request Defaults improvements:
You can now configure Source Address (IP Spoofing like feature) and "Save response as MD5 hash" in Advanced Tab
Reporting improvements
New Reporting Feature generating dynamic Graphs in HTML pages (APDEX, Summary report and Graphs)
A dynamic HTML report can now be generated either at the end of a load test or from a result file whenever you want. See Generating dashboard for more details. This report provides the following metrics:
APDEX (Application Performance Index) table that computes the APDEX based on configurable values for tolerated and satisfied thresholds
A request summary graph showing the Success and failed transaction percentage:
A Statistics table providing in one table a summary of all metrics per transaction including 3 configurable percentiles :
An error table providing a summary of all errors and their proportion in the total requests :
Zoomable chart where you can check/uncheck every transaction to show/hide it for:
Response times Over Time :
Bytes throughput Over Time :

You can now use a regular expression to select the samplers you want to filter. Use parameter: useRegexpForSamplersList=true and put a regex in pararameter samplersList
Protocols and Load Testing improvements
Migration to HttpClient 4.5.2 has been started. Although not completely finished, it improves many areas in JMeter
Migration to HttpClient 4.5.2 improves the following fields of JMeter:
Support of recent RFC like HTTP State Management Mechanism RFC-6265 for Cookies, you should use now HC4CookieHandler in HTTP Cookie Manager component and select standard Cookie policy
Server Name Indication (SNI) support for HttpClient4 implementation
Improved and better performing validation mechanism for Stale connections and Keep-Alive management, see properties httpclient4.validate_after_inactivity and httpclient4.time_to_live
Many bug fixes since previous version 4.2.6 used in JMeter 2.13, see HttpClient 4.5.X release notes
Better support of HTTP RFC 2616 / RFC 7230 and fixes to issues with deflate compression management
Parallel Downloads is now realistic and scales much better:
Parsing of CSS imported files (through @import) or embedded resources (background, images, …)
Lazy initialization of SSL context: For 15 Threads 138% more sampling in 5 minutes for HTTP only tests. Gain increases as number of threads increases
Rework of Connection management for Parallel Download: This better simulates current browser behaviour and improves throughput. For 15 Threads 135% extra samples in 5 minutes.
Reuse of Threads used for Parallel downloads through a ThreadPool: This improves throughput and increases JMeter scalability for such tests
Total of 750% more throughput found on test with 15 threads, the more threads you have the more the gain
You can now compute and store just the MD5 of embedded resources instead of storing the entire response, this can be done by setting the property httpsampler.embedded_resources_use_md5=true
Introduction of Sample Timeout feature:
This new Sample Timeout Pre-Processor allows you to apply a Timeout on the elements that are in its scope. In the screenshot below the 10 second timeout applies to the Debug Sampler and HTTP Request elements.
JDBC request now uses DBCP2 pool
JDBC Request and JDBC Connection Configuration have been updated to replace old Excalibur Pool by Apache Commons DBCP2 pool. As a consequence properties have been migrated to equivalent when available and UI has been updated. Note that unlike Excalibur, Commons DBCP uses the validation query when creating the pool. So make sure the query is valid. The default query suits many databases, but not all - for example Oracle requires 'SELECT 1 FROM DUAL' or similar.
UX Improvements:
Better display in HiDPI screens
New Icon look and Logo:
JMeter has a new Logo created by Felix Schumacher.
Icons have also been refreshed to give a more modern style and make them more meaningful
Lots of fixes of annoying little bugs:
Around 40 UI fixes have been made to either fix buggy, confusing behaviour or simplify usage by not allowing incompatible options to be selected
Improved Thread Group UI and related actions (Start, Start No Timers, Validate)
Creating and testing a Test Plan before Load Test has been much simplified by allowing you to only start a selection of Thread Group, start them without applying Timers (thus gaining time) or start them using a new Validation mode. This validation mode allows you to start a Thread Group (without modifying it) with 1 thread, 1 iteration and without applying timers. This validation mode can be customized.
New shortcuts:
Add most used elements (Ctrl + 0 … Ctrl + 9), configurable through gui.quick_XXX properties
Shortcuts to expand nodes
Core improvements:
Configuration simplification with better defaults
Default values for many properties have been modified to make JMeter configuration optimal Out of the box. Read "Incompatible changes" section for more details.
Apache Groovy bundled with JMeter
Apache Groovy, the well-known JVM scripting language, is now bundled with Apache JMeter in lib folder. This allows you to use it immediately through JSR223 Elements by selecting the Groovy language.
Superflous and old properties removed:
Old properties that existed to maintain backward compatibility or to offer some superflous customization have been removed. Read "Incompatible changes" section to see which properties have been removed.
Code and documentation improvements:
Migration to Java7 source code and use of its syntactic sugar
Major code cleanups
Full review of documentation and improvement both in content and presentation
Improvements to unit tests:
Migration of many tests to JUnit 4
Better management of Headless tests
More Unit Tests
Dependencies refresh:
Deprecated Libraries dropped or replaced by up to date ones:
Excalibur replaced by commons-dbcp
htmllexer, htmlparser removed
soap removed
jdom removed
Slf4j can now be used within Plugins and core code
You can now use SLF4J logging wrapper in your custom plugins or org.apache.jmeter.protocol.java.sampler.AbstractJavaSamplerClient subclasses.
Incompatible changes:
Since version 3.0, Groovy-2.4.6 is bundled with JMeter (lib folder), ensure you remove old version or referenced versions through properties search_paths or user.classpath
Since version 3.0, jmeter.save.saveservice.assertion_results_failure_message property value is true, meaning CSV file for results will contain an additional column containing assertion result response message, see Bug 58978
Since version 3.0, jmeter.save.saveservice.print_field_names property value is true, meaning CSV file for results will contain field names as first line in CSV, see Bug 58991
Since version 3.0, jmeter.save.saveservice.idle_time property value is true, meaning CSV/XML result files will contain an additional column containing idle time between samplers, see Bug 57182
In RandomTimer class, protected instance timer field has been replaced by getTimer() protected method, this is related to Bug 58100. This may impact 3rd party plugins.
Since version 3.0, you can use Nashorn Engine (default javascript engine is Rhino) under Java8 for Elements that use Javascript Engine (__javaScript, IfController). If you want to use it, use property javascript.use_rhino=false, see Bug 58406.
Note: in a future version, we will switch to Nashorn by default. Users are encouraged to report any issue related to using Nashorn instead of Rhino.
Since version 3.0, JMS Publisher will reload contents of file if Message source is "From File" and the "Filename" field changes (e.g. if it uses a variable that has changed)
org.apache.jmeter.gui.util.ButtonPanel has been removed, if you use it in your 3rd party plugin or custom development ensure you update your code. See Bug 58687
Property jmeterthread.startearlier has been removed. See Bug 58726
Property jmeterengine.startlistenerslater has been removed. See Bug 58728
Property jmeterthread.reversePostProcessors has been removed. See Bug 58728
Property jmeter.toolbar.display has been removed, the toolbar is now always displayed. See Bug 59236
Property jmeter.errorscounter.display has been removed, the errors/warnings counter is now always displayed. See Bug 59236
Property xml.parser has been removed, it is not used anymore as org.apache.jmeter.util.JMeterUtils#getXMLParser has been deprecated and is not used either. See Bug 59236
Summariser listener now shows the duration in the format HH:mm:ss (Hour:Minute:Second), it previously showed the duration in seconds. See Bug 58776
org.apache.jmeter.protocol.http.visualizers.RequestViewHTTP.getQueryMap signature has changed, if you use it ensure you update your code. See Bug 58845
JMS Subscriber will consider a sample to be an error if the number of received messages is not equal to expected number of messages. It previously considered a sample OK if at least 1 message was received. See Bug 58980
Since version 3.0, HTTP(S) Test Script recorder defaults to using port 8888 (as configured when using Recording Template). See Bug 59006
Since version 3.0, the parser for embedded resources (replaced since 2.10 by Lagarto based implementation) which relied on the htmlparser library (HtmlParserHTMLParser) has been dropped along with its dependencies.
Since version 3.0, support for reading old Avalon format JTL (result) files has been removed, see Bug 59064
Since version 3.0, the default property value for http.java.sampler.retries has been changed to 0 (no retry by default) to align it with the behaviour of HttpClient4.
Note also that its meaning has changed: before 3.0, http.java.sampler.retries=1 meant No Retry (i.e. total tries = 1), since 3.0 http.java.sampler.retries=1 means 1 retry. (Note: this only applies to the Java HTTP Sampler)
See Bug 59103
Since 3.0, the following deprecated classes have been dropped
org.apache.jmeter.protocol.http.modifier.UserParameterXMLContentHandler
org.apache.jmeter.protocol.http.modifier.UserParameterXMLErrorHandler
org.apache.jmeter.protocol.http.modifier.UserParameterXMLParser
httpsampler.await_termination_timeout has been replaced by httpsampler.parallel_download_thread_keepalive_inseconds which is now the keep alive time for the parallel download threads (in seconds).
JDBC Request has been updated to use commons-dbcp2, since then the behaviour is slightly different, ensure you have a correct "Validation Query" for your database. See Bug 58786
The following jars have been removed:
excalibur-datasource-2.1.jar (see Bug 59156)
excalibur-instrument-1.0.jar (see Bug 58786)
excalibur-pool-api-2.1.jar (see Bug 58786)
excalibur-pool-impl-2.1.jar (see Bug 58786)

htmlparser-2.1.jar (see Bug 59037)
soap-2.3.1.jar
jdom-1.1.3.jar (see Bug 59156)
Maximum number of redirects allowed by JMeter is now 20, it was previously 5. This can be changed with the property httpsampler.max_redirects. See Bug 59382
Deprecated and removed elements:
MongoDB elements (MongoDB Source Config, MongoDB Script) have been deprecated and will be removed in the next version of JMeter. They do not appear anymore in the menu, if you need them modify not_in_menu property. The JMeter team advises not to use them anymore. See Bug 58772
WebService(SOAP) Request and HTML Parameter Mask which were deprecated in 2.13 version, have now been removed following our deprecation strategy. Classes and properties which were only used by those elements have been dropped:
org.apache.jmeter.protocol.http.util.DOMPool
org.apache.jmeter.protocol.http.util.WSDLException
org.apache.jmeter.protocol.http.util.WSDLHelper
Property soap.document_cache
JAR soap-2.3.1 has been also removed

New in Apache JMeter 2.13 (Mar 16, 2015)

New and Noteworthy:
New Elements:
New Async BackendListener with Graphite implementation
A new Async BackendListener has been added to allow sending result data to a backend listener. JMeter ships with a GraphiteBackendListenerClient that allows sending results to a Graphite server using Pickle ot Plaintext protocols. You can implement your own backend by extending AbstractBackendListenerClient. This backend could be a database (JDBC), a Message Oriented Middleware (JMS), a Webservice or anything you want.
Core Improvements:
New connect time metric:
Starting with this version a new metric called connectTime has been added. It represents the time to establish connection. By default it is not saved to CSV or XML, to have it saved add to user.properties:
jmeter.save.saveservice.connect_time=true
Aggregate Graph and Report:
The listeners Aggregate Graph and Aggregate Report previously showed only the 90 percentile (historical behavior), the 95 percentile and the 99 percentile have been added and are customizable. To setup the percentiles value you want, add to user.properties:
aggregate_rpt_pct1=90
aggregate_rpt_pct2=95
aggregate_rpt_pct3=99
HTTP(S) Test Script Recorder: Now component is able to detect authentication schemes and automatically adds a pre-configured HTTP Authorization Manager with the correct Mechanism.
HTTP Request: The CalDAV verbs (Calendar extensions to WebDAV) REPORT and MKCALENDAR have been added in the HTTP Request sampler.
JDBC Request: The ResultSet can be get as a object, this allows to handle more easily the results after in BeanShell, JSR223 scripts...
Distributed Testing: To allow better usage of Distributed Testing in the cloud, retry behaviour has been added when starting test on servers. Read this for more details.
Distributed Testing performance: Since JMeter 2.13, Stripping modes (StrippingBatch being the default mode) now also strip responses from SubResults improving consumed network bandwidth.
Documentation refresh:
A new style for website (responsive and more up to date) has been created by Felix Schumacher. Documentations have been refreshed particularly:
Building a Webservice Test Plan
Best Practices
Help! My boss wants me to load test our application!
GUI Improvements:
Module Controller: The Module Controller now shows the target controller in a tree view (instead of combo list).
Toolbar:
JMeter's toolbar has been refreshed for some icons (start, toogle, etc.). Three sizes are now avialable for the icons: 22x22, 32x32 and 48x48.
The property to define your prefered size is:
jmeter.toolbar.icons.size=value
HTTP(S) Test Script Recorder:
If your Test Plan does not contains a Recording Controller, a new warning message will appear if the HTTP(S) Test Script Recorder is configured to send the samples into a Recording Controller.
Incompatible changes:
Since 2.13, Aggregate Graph, Summary Report and Aggregate Report now export percentages to %, before they exported the decimal value which differed from what was shown in GUI
Third party plugins may be impacted by fix of Bug 57586, ensure that your subclass of HttpTestSampleGui implements ItemListener if you relied on parent class doing so.
Report package has been removed, ApacheJMeter_report.jar is not generated anymore as a consequence, see Bug 57269

New in Apache JMeter 2.12 (Nov 11, 2014)

New and Noteworthy:
Java 8 support
Now, JMeter 2.12 is compliant with Java 8.
New Elements:
Critical Section Controller - The Critical Section Controller allow to serialize the execution of a section in your tree. Only one instance of the section will be executed at the same time during the test.
DNS Cache Manager - The new configuration element DNS Cache Manager (see Bug 56841 ) improves the testing of:
CDN (Content Delivery Network)
DNS load balancing.
Load Balancers like Amazon Elastic Load Balancer
Core Improvements:
Smarter Recording of Http Test Plans
Test Script Recorder has been improved in many ways
Better matching of Variables in Requests, making Test Script Recorder variabilize your sampler during recording more versatile
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
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
Support of Webdav requests:
You can now test against WebDav server using HttpClient4 Implementation of Http Request
Better handling of embedded resources:
When download embedded resources is checked, JMeter now uses User Agent header to download or not resources embedded within conditionnal comments as per About conditional comments .
Ability to customize Cache Manager (Browser cache simulation) handling of cached resources
You can now configure the behaviour of JMeter when a resource is found in Cache, this can be controlled with cache_manager.cached_resource_mode property
JMS Publisher / JMS Point-to-Point:
Add JMSPriority and JMSExpiration fields for these samplers.
Mail Reader Sampler:
You can now specify the number of messages that want you retrieve (before all messages were retrieved). In addition, you can fetch only the message header now.
SMTP Sampler:
Adding the Connection timeout and the Read timeout to the SMTP Sampler.
Synchronizing Timer:
Adding a timeout to define the maximum time to waiting of the group of virtual users.
Performance improvements:
A big improvement in performances of Functions has been made by lifting useless synchronization. It concerns all functions except __StringFromFile, __XPath and __BeanShell, see Bug 57114
__jexl2 performances have been improved to avoid contention point, see Bug 56708
GUI Improvements:
Undo/Redo support - 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 undo.history.size=25
View Results Tree:
Improve the ergonomics of View Results Tree by changing placement of Renderers and allowing custom ordering (with the property view.results.tree.renderers_order ).
Response Time Graph:
Adding the ability for the Response Time Graph listener to save/restore format its settings in/from the jmx file.
Log Viewer:
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.
File Opening:
Now, "Open File dialog" uses last opened file folder as start folder, see Bug 52707
Incompatible changes:
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 Bug 57025 . 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 jmeter.save.saveservice.thread_counts=false
Since JMeter 2.12, Mail Reader Sampler will show 1 for number of samples instead of number of messages retrieved, see Bug 56539
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 Bug 54778 . You can choose between different ways to handle this case, see cache_manager.cached_resource_mode in jmeter.properties.
Since JMeter 2.12, Log Viewer will no more clear logs when closed and will have logs available even if closed. See Bug 56920 . Read Hints and Tips > Enabling Debug logging for details on configuring this component.

New in Apache JMeter 2.4 (Jul 4, 2011)

New in Apache JMeter 2.3.2 (Apr 23, 2009)

Incompatible changes:
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.
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.
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)
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 '.
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.
