--- title: "JMeter 3.2 Release Notes" description: "Apache JMeter 3.2 release notes with 56 improvements and 41 bug fixes, plus upgrade notes from the official changelog." url: https://docs.jmeter.ai/releases/3-2/ lastUpdated: 2026-10-01 source: docs.jmeter.ai --- # JMeter 3.2 Release Notes > **About these release notes** > This page lists every documented change shipped in Apache JMeter 3.2, generated from the official changelog. For download and upgrade guidance, see [Download JMeter](/reference/download-jmeter/). ## Change summary | Section | Changes | | --- | --- | | Incompatible changes | 20 | | Improvements | 56 | | Bug fixes | 41 | | Non-functional changes | 18 | ## New and Noteworthy ## Incompatible changes - JMeter requires now at least a Java 8 version to run. - JMeter logging has been migrated to SLF4J and Log4j 2, this involves changes in the way configuration is done. JMeter now relies on standard [Log4j 2 configuration](https://logging.apache.org/log4j/2.x/manual/configuration.html) in file `log4j2.xml` See `Logging changes` section below for further details. - The following jars have been removed after migration from LogKit to SLF4J (see [Bug 60589](https://bz.apache.org/bugzilla/show_bug.cgi?id=60589)): - ApacheJMeter_slf4j_logkit.jar - avalon-framework-4.1.4.jar - commons-logging-1.2.jar - excalibur-logger-1.1.jar - logkit-2.0.jar - The `commons-httpclient-3.1.jar` has been removed after drop of HC3.1 support(see [Bug 60727](https://bz.apache.org/bugzilla/show_bug.cgi?id=60727)) - JMeter now sets through `-Djava.security.egd=file:/dev/urandom` the algorithm for secure random - Process Sampler now returns error code 500 when an error occurs. It previously returned an empty value. - In `org.apache.jmeter.protocol.http.sampler.HTTPHCAbstractImpl` two protected static fields (`localhost` and `nonProxyHostSuffixSize`) have been renamed to (`LOCALHOST` and `NON_PROXY_HOST_SUFFIX_SIZE`) to follow static fields naming convention - JMeter now uses by default Oracle Nashorn engine instead of Mozilla Rhino for better performances. This should not have an impact unless you use some advanced features. You can revert back to Rhino by settings property `javascript.use_rhino=true`. You can read this [migration guide](https://wiki.openjdk.java.net/display/Nashorn/Rhino+Migration+Guide) for more details on Nashorn. See [Bug 60672](https://bz.apache.org/bugzilla/show_bug.cgi?id=60672) - [Bug 60729](https://bz.apache.org/bugzilla/show_bug.cgi?id=60729)The Random Variable Config Element now allows minimum==maximum. Previous versions logged an error when minimum==maximum and did not set the configured variable. - [Bug 60730](https://bz.apache.org/bugzilla/show_bug.cgi?id=60730)The JSON PostProcessor now sets the `_ALL` variable (assuming `Compute concatenation var` was checked) even if the JSON path matches only once. Previous versions did not set the `_ALL` variable in this case. #### Removed elements or functions - SOAP/XML-RPC Request has been removed as part of [Bug 60727](https://bz.apache.org/bugzilla/show_bug.cgi?id=60727). Use HTTP Request element as a replacement. See [Building a WebService Test Plan](/./usermanual/build-ws-test-plan/) - [Bug 60423](https://bz.apache.org/bugzilla/show_bug.cgi?id=60423)Drop Monitor Results listener - Drop deprecated class `org.apache.jmeter.protocol.system.NativeCommand` - Drop deprecated class `org.apache.jmeter.protocol.http.config.gui.MultipartUrlConfigGui` - Drop deprecated class `org.apache.jmeter.testelement.TestListener` - Drop deprecated class `org.apache.jmeter.reporters.FileReporter` - Drop deprecated class `org.apache.jmeter.protocol.http.modifier.UserSequence` - Drop deprecated class `org.apache.jmeter.protocol.http.parser.HTMLParseError` - Drop unused methods `org.apache.jmeter.protocol.http.control.HeaderManager#getSOAPHeader` and `org.apache.jmeter.protocol.http.control.HeaderManager#setSOAPHeader(Object)` - `org.apache.jmeter.protocol.http.util.Base64Encode` has been deprecated, you can use `java.util.Base64` as a replacement #### Logging changes JMeter logging has been migrated to SLF4J and Log4j 2. This affects logging configuration and 3rd party plugins (if they use JMeter logging). The following sections describe what changes need to be made. Setting the logging level and log file The default logging level can be changed on the command-line using the `-L` parameter. Likewise the `-l` parameter can be used to change the name of the log file. However the `log_level` properties no longer work. The default logging levels and file name are defined in the `log4j2.xml` configuration file in the launch directory (usually `JMETER_HOME/bin`) > **Note** > If you need to change the level programmatically from Groovy code or Beanshell, you need to do the following: > > ```java > import org.apache.logging.log4j.core.config.Configurator; > ⋮ > final String loggerName = te.getClass().getName(); // te being a JMeter class > Configurator.setAllLevels(loggerName, Level.DEBUG); > ``` Changes to 3rd party plugin logging > **Note** > 3rd party plugins should migrate their logging code from logkit to slf4j. This is fairly easy and can be done by replacing: > > ```java > import org.apache.jorphan.logging.LoggingManager; > import org.apache.log.Logger; > ⋮ > private static final Logger log = LoggingManager.getLoggerForClass(); > ``` > > By: > > ```java > import org.slf4j.Logger; > import org.slf4j.LoggerFactory; > ⋮ > private static final Logger log = LoggerFactory.getLogger(YourClassName.class); > ``` ## Improvements #### HTTP Samplers and Test Script Recorder - [Bug 59934](https://bz.apache.org/bugzilla/show_bug.cgi?id=59934)Fix race-conditions in CssParser.

Ensure you use the most up to date version. JMeter logging has been migrated to SLF4J and Log4j 2. This affects configuration and 3rd party plugins, see below **“Logging changes”**. Starting with JMeter version 3.2 the number of results in View Results Tree is limited by default to 500 entries. If you want more entries, you have to set the property `view.results.tree.max_results` to a higher value, or to `0`, if you don’t want to impose any limit. You can set the property in bin/user.properties. More info might be found [here](/usermanual/component-reference/#View_Results_Tree). ### Core improvements - JMeter now provides a new BackendListener implementation that interfaces InfluxDB. ![changes/3.2/backend_influxdb.png](/images/screenshots/changes/3.2/backend_influxdb.png) This implementation sends data using Asynchronous HTTP calls to InfluxDB through its [HTTP API](https://docs.influxdata.com/influxdb/v1.2/guides/writing_data/) and give you the following graphs with annotations: ![backend_listener_influxdb_graph.png](/images/screenshots/backend_listener_influxdb_graph.png) - DNS Cache Manager now has a table to allow static host resolution. ![changes/3.2/dns_cache_manager_static_hosts.png](/images/screenshots/changes/3.2/dns_cache_manager_static_hosts.png) - JMS Publisher and Subscriber now allow reconnection on error with pause. ![changes/3.2/jms_publisher_reconnect.png](/images/screenshots/changes/3.2/jms_publisher_reconnect.png) ![changes/3.2/jms_subscriber_reconnect_pause.png](/images/screenshots/changes/3.2/jms_subscriber_reconnect_pause.png) - Variables in JMS Publisher are now supported for all types of messages. Add the encoding type of the file to parse its content - XPath Extractor now allows extraction randomly, by index or for all matches. ![changes/3.2/xpath_extractor_matchno.png](/images/screenshots/changes/3.2/xpath_extractor_matchno.png) - Response Assertion now allows to work on Request Header, provides a “OR” combination and has a better cell renderer ![changes/3.2/response_assertion.png](/images/screenshots/changes/3.2/response_assertion.png) - JMeter now uses Oracle Nashorn Javascript engine instead of Rhino. This provides a faster execution of Javascript. - HTTP HC4 Implementation now provides preemptive Basic Auth enabled by default - Embedded resources download in CSS has been improved to avoid useless repetitive parsing to find the resources - An important work on code quality and code coverage with tests has been done since Sonar has been setup on the project. You can see Sonar report [here](https://builds.apache.org/analysis/overview?id=12927). ### UX improvements - When running a Test, GUI is now more responsive and less impacting on memory usage thanks to a limitation on the number of Sample Results listeners hold and a rework of the way GUI is updated - HTTP Request GUI has been simplified and provides more place for parameters and body. ![changes/3.2/http_request.png](/images/screenshots/changes/3.2/http_request.png) - HTTP(S) Test Script Recorder has been simplified and clarified. ![changes/3.2/http_recorder_1.png](/images/screenshots/changes/3.2/http_recorder_1.png) ![changes/3.2/http_recorder_2.png](/images/screenshots/changes/3.2/http_recorder_2.png) - A `replace` feature has been added to Search feature to allow replacement in some elements. ![changes/3.2/search_replace.png](/images/screenshots/changes/3.2/search_replace.png) :::note ReplaceAll does not do replacement on all elements, it does it on: - HeaderManager: Replacement in values - Http Request: Replacement in Arguments, Path and Host ::: - View Results Tree now provides a more up to date Browser renderer which requires JavaFX. - You can now add through a contextual menu think times, this will add think times between samplers and Transaction Controllers of selected node. ![changes/3.2/menu_add_think_times.png](/images/screenshots/changes/3.2/menu_add_think_times.png) - You can now apply a naming policy to children of a Transaction Controller. A default policy exists but you can implement your own through `[org.apache.jmeter.gui.action.TreeNodeNamingPolicy](/./api/org/apache/jmeter/gui/action/TreeNodeNamingPolicy/)` and configuring property `naming_policy.impl` ![changes/3.2/menu_apply_naming_policy.png](/images/screenshots/changes/3.2/menu_apply_naming_policy.png) - Sorting per column has been added to View Results in Table, Summary Report, Aggregate Report and Aggregate Graph elements. ![changes/3.2/sorting.png](/images/screenshots/changes/3.2/sorting.png) ### Report/Dashboard improvements - Statistics have been reorganized to clarify report: ![dashboard/report_statistics.png](/images/screenshots/dashboard/report_statistics.png) - It is now possible to customize APDEX thresholds per transaction based on regular expression or sample name. The below example will apply different thresholds for samples sample(\d+), sampleA and scenarioB than default ones (500 and 1500 for satisfied and tolerated thresholds) declared: `jmeter.reportgenerator.apdex_satisfied_threshold=500 jmeter.reportgenerator.apdex_tolerated_threshold=1500 jmeter.reportgenerator.apdex_per_transaction=sample(\\d+):1000|2000;\ sampleA:3000|4000;\ scenarioB:5000|6000` ### Documentation improvements - PDF Documentations have been migrated and updated to HTML user manual ## Useful links - [Download JMeter](/reference/download-jmeter/) - [Getting started guide](/getting-started/get-started/) - [All release notes](/releases/) - [Current changes page](/user-manual/changes/) - [History of previous changes](/user-manual/changes-history/)
