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)

  • 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)

  • Developer: Allow consumers of XmlFile to disable fsync(2). (pull 5599)

What's new in 2.302 (2021-07-13)

  • Optimize access control checks affecting (at least) Pipeline node steps. (pull 5586)
