  • Graphs now scale correctly on high resolution screens. (pull 5697)
  • The checkbox labeled "Enable Agent → Controller Access Control" in the form "Configure Global Security" would always start out as disabled. Submitting the form without checking it would then cause a configuration change (regression in 2.307). (pull 5694)
  • Load classes from plugins in parallel for faster startup on multicore machines. (issue 23784)
  • Internal: Experimental support for URLClassLoader can be enabled by setting hudson.ClassicPluginStrategy.useAntClassLoader=false. (pull 5698)

What's new in 2.308 (2021-08-24)

  • Use SVGs over PNGs for the sidebar when possible. Breadcrumb bar/logo/menu items are now correctly aligned on the left together. Move old war/images folder to webapp so they can be used in frontend - the SVGs are now in the webapp/images/svgs folder. (pull 5663)
  • Update appearance for feed bar and description button to be modern and consistent. (pull 5664)
  • When the buildWithParameter API is called, if the requests with the same parameters in the queue are merged, the http response code of the request uses a more appropriate 303(see other) instead of 201(created). (issue 66105)
  • Warn about use of master in a label expression when that's no longer in use. (pull 5674)
  • Use full URL character encoding for the generated inbound agent launch string. (pull 5636)

  • Developer: Bump spring-security-bom from 5.5.1 to 5.5.2. (pull 5672Spring project spring-security 5.5.2 release notes)

What's new in 2.307 (2021-08-17)

The default Docker images for Jenkins 2.307 ('2.307', 'latest', 'alpine', 'slim', ...) use Java 11 unless specifically tagged with the jdk8 string. See the Docker images use Java 11 by default blog post for more details.
  • Replace the term "master" with "controller" (for the main Jenkins application) or "built-in node" in user interface strings and documentation as appropriate. (pull 5425)
  • Add migration code to change the node name (e.g. NODE_NAME environment variable) and label of the built-in node only after explicit migration by an administrator. New installations get the new node and label immediately. If a job definition, Pipeline definition, or tool installer reference must be tied to the built-in node, it should use the label "built-in". (Built-In Node Name and Label Migration)
  • Add the system property jenkins.model.Jenkins.nodeNameAndSelfLabelOverride to specify a different node name and label for the built-in node (e.g. for Configuration as Code use cases) than the one otherwise determined. This will not affect other uses of the node name, such as the URL to the built-in node (now /computer/(built-in)/). (pull 5425)
  • GDSL file in jenkins-core library no longer reports an IllegalStateException when used in IntelliJ IDEA. (pull 5662)
  • Improve layout of console output header. (pull 5507)
  • Use the SVG version of the Jenkins text logo instead of the PNG. (pull 5660)
  • Developer: Jenkins now uses an updated version of the AntClassLoader class with fewer custom patches. (pull 5656)
  • Removed: The Woodstox implementation of the StAX API has been removed from Jenkins core. Users of the Azure Artifact Manager, Azure Container Agents, Azure Storage, and Azure SDK API plugins must upgrade those plugins to the latest versions in lockstep with this core upgrade. Plugins that consume Woodstox should depend on it directly or via the Jackson 2 API plugin. (pull 5651Woodstox implementationStAX APIAzure Artifact Manager pluginAzure Container Agents pluginAzure Storage pluginAzure SDK API pluginJackson 2 API plugin)

What's new in 2.306 (2021-08-10)

  • Provide working "Help About" links for Jenkins CLI, Jenkins core, and Jenkins war. (issue 64666)
  • Developer: AntClassloader will now ignore files that are part of the classpath but not zip files when scanning for resources. It used to throw an exception. (pull 5650)

  • Bump matrix-auth from 2.6.7 to 2.6.8. (pull 5630)
  • Remove support for native JNR (Java Native Runtime) chmod(2) and stat(2) implementations as opposed to NIO (Java non-blocking I/O) via the hudson.Util.useNativeChmodAndMode system property. This system property no longer has any effect. (pull 5606)
  • Developer: Allow consumers of XmlFile to disable fsync(2). (pull 5599)

(pull 5526Vertx pluginSlave Prerequisites plugin)
  • Developer: Remove JTidy dependency from Jenkins core. Plugins that use JTidy functionality must be updated to explicitly declare a dependency on JTidy rather than relying on Jenkins core to provide this library. (pull 5521NIS notification lamp plugin)

  • Display Pipeline builds among user build history and remove incorrect warning about view build history. (issue 59412)
