2.277.1

March 10, 2021
As described in the Major changes in the weekly release line blog post, this release improves key user interface components. Configuration user interfaces now use html div markup to present a better layout than the previous html table layout. Configuration pages are now easier to read, easier to understand, and work better on a wide range of screens. See the Jenkins issue tracker for a list of plugins known to have issues with the change.

 

As described in the Spring and XStream updates (breaking changes!) blog post, this release updates and replaces outdated internal components. The Acegi security library used for authentication has been replaced by Spring Security (JEP-227). See the Spring Security compatibility table for the latest plugin compatibility status. A fork of the XStream library used to read and write XML files has been replaced by the upstream version of XStream (JEP-228). See the XStream compatibility table for the latest plugin compatibility status.

 

Known IssuesIf your Jenkins instance was created before Jenkins 2.4 or 2.7.1 LTS, a Setup Wizard may appear on the startup after the upgrade. In such a case, a Jenkins admin may need to skip the plugin installation. See the upgrade guide for the detailed guidelines.

  • Internal: Define enabling/disabling in ParameterizedJob rather than AbstractProject. issue 27299
  • Fixed Pipeline compatibility for a number of CLI commands (delete-builds, list-changes, console, set-build-description, and set-build-display-name), as well as some issues affecting error reporting in other commands when used with Pipeline. issue 30785, issue 41527
  • Enable simpler syntax for upstream build trigger in pipelines. issue 34464
  • Minor optimization to queue maintenance routines and printing of console notes, mainly for the benefit of Pipeline node blocks. issue 45553
  • If you have the Authorize Project plugin installed and configured, its configuration will now be treated as final with respect to the behavior of Job/Build checks from Build other projects and Build after other projects are built. Formerly, if a Per-project configurable Build Authorization was enabled globally but some projects did not specify an Authorization, the two aforementioned checks would automatically fall back to checking as anonymous (typically denying build permission). To restore the former behavior, explicitly configure a Project default Build Authorization to be Run as anonymous. Note that this will affect all build-scoped permission checks, including for example Agent/Build. issue 22949

2.60.1

June 21, 2017
2.60.1 is the first Jenkins LTS release that requires Java 8 to run. If you're using the Maven Project type, please note that it needs to use a JDK capable of running Jenkins, i.e. JDK 8 or up. If you configure an older JDK in a Maven Project, Jenkins will attempt to find a newer JDK and use that automatically. If your SSH Build Agents fail to start and you have the plugin install the JRE to run them, make sure to update SSH Build Agents Plugin to at least version 1.17 (1.20 recommended).

  • Update Remoting to 3.4 in order to properly terminate the channel in the case Errors and Exceptions. issue 39835
  • Check for Updates button in the Plugin Manager was hidden in the Updates tab when there was no plugins updates available. issue 39971
  • SSHD Module: Handshake was failing (wrong shared secret) 1 out of 256 times due to SSHD-330. issue 40362
  • Performance: Use bulk change when submitting Job configurations to minimize the number of sequential config.xml write operations. issue 40435
  • Jobs were hanging during process termination on the Solaris 11 Intel platform, regression in 2.20. issue 40470

Enhancement
  • Update to Winstone 3.2 to support ad-hoc certificate generation on Java 8 (using unsupported APIs). This option is deprecated and will be removed in a future release.

Bug fix
  • Redirect to login page in the case of authorisation error when checking connectivity to the Update Center. issue 39741
  • WinP 1.24: Native class now tries loading DLLs from the temporary location. issue 20913

What's new in 1.625.1 (2015/10/14)

1.625.1 is the first Jenkins LTS release that requires Java 7 to run. If you're using the Maven Project type, please note that it needs to use a JDK capable of running Jenkins, i.e. JDK 7 or up. If you configure an older JDK in a Maven Project, Jenkins will attempt to find a newer JDK and use that automatically. If your SSH agents fail to start and you have the plugin install the JRE to run them, make sure to update SSH Build Agents Plugin to at least version 1.10.
