2.89.1 (2017-12-06) 中有什么新内容

Upgrading to Jenkins 2.89.1 does not install the Command Launcher plugin (see below) as it should. If you're using the Launch agent via execution of command on the master launch method for agents, or cloud provider plugins, make sure to manually install the plugin after upgrading, and restart Jenkins afterwards.

2.73.1 (2017-09-13) 中有什么新内容

Two regressions since the previous LTS release have been identified in 2.73.1. One involved Remoting (agent) connections and the other concerns failures to use passphrase-protected ed25519 SSH keys. Please see the LTS upgrade guide for 2.73.1 for more information.
自 2.73 以来的变更:
Notable changes since 2.60.3:
  • Upgrade Groovy from 2.4.8 to 2.4.11. (Groovy 2.4.9 changelogGroovy 2.4.10 changelogGroovy 2.4.11 changelog)
  • Integration of Winstone 4: Upgrade bundled Jetty from 9.2.15.v20160210 to 9.4.5.v20170502. This removes support for the deprecated SPDY protocol. The --spdy parameter has been removed accordingly and Jenkins may refuse to start if it's set. (full changelog)
  • Jetty 9.4.5: Prevent the 400 Bad Host header error for HttpChannelOverHttp when operating behind reverse proxy. (issue 40693corresponding Jetty issue)
  • Winstone 4.1: Add Jetty HTTP/2 connector and corresponding options for Winstone-Jetty. (issue 45438enabling HTTP/2 support in Winstone-Jetty)
  • Update Remoting from 3.7 to 3.10 adding opt-in support for work directories and improving logging in Jenkins agents. (work directory documentationlogging documentationremoting changelogissue 39370)
  • Enable Remoting work directories by default for newly created agents launched via JNLP (Java Web Start Launcher). (issue 44112feature documentation)
  • SSHD Module 2.0: Update from SSHD Core 0.14.0 to Apache MINA SSHD 1.6.0 in Jenkins core and Jenkins CLI. (changelogplugin compatibility noticeissue 43668)
  • SSHD Module 2.0: Enable aes192ctr and aes256ctr ciphers if JVM supports unlimited-strength encryption. (issue 39738)
  • Update WinP from 1.24 to 1.25 to improve performance and diagnostics of issues like JENKINS-30782. (full changelog)
  • Update jnr-posix from 3.0.1 to 3.0.41 to pick up improvements and fixes in the POSIX platforms support. (pull 2904)
  • Freestyle projects may now list Pipeline jobs as downstream and trigger them, without needing to use the Parameterized Trigger plugin or reverse triggers ("Build after other projects are built"). (issue 28113)
  • 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 30785issue 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)
  • Internal API: Tasks.getAuthenticationOf now honors authentication contributed by QueueItemAuthenticatorProvider extensions. (pull 2880)
  • Moved agent port and protocol configuration out of "security" (authentication and authorization) block in Configure Global Security. (issue 4478)
  • Don't reload user records from disk unless explicitly requested to improve performance of user record access. (issue 45737)
  • Plugin Development: Jenkins now no longer publishes a war-for-test artifact. Plugins using 2.64 or a later version of Jenkins (including 2.73.1) as baseline need to use plugin parent POM 2.30 or later. (issue 24064)

2.60.3 (2017-08-17) 中有什么新内容

  • Contributions to the PATH environment variable could result in malformed values on agents on a platform different from master's. (issue 14807)
  • Robustness improvements related to agent connections. (issue 43496issue 38527)
  • JNLP for launching agents now requests Java 8. (issue 45679)
  • Prevent NullPointerException in Jenkins#getRootURL() while the instance is not fully loaded yet. (issue 34914)
  • Fix NullPointerException when calculating culprits. (issue 45516)
  • The reload-configuration CLI command now waits until the reload is finished, and returns an error code if the reload failed. (issue 45256)
  • Remove the "JNLP" protocol references from the TCP Agent Listener log messages. (issue 44103)

2.60.2 (2017-07-19) 中有什么新内容

  • Don't check whether disabled administrative monitors are active or not on the Manage Jenkins page. (issue 44608)
  • When starting the jenkins.war directly, properly check for Java 8 as minimum instead of Java 7 before proceeding. (issue 44764)
  • Prevent NullPointerException when calling restart CLI command (regression in 2.57). (issue 44769)
  • Prevent possible NullPointerException when listing remote directories using the FilePath#list() and FilePath#listDirectories() APIs. (issue 44942)

2.60.1 (2017-06-21) 中有什么新内容

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 Slaves fail to start and you have the plugin install the JRE to run them, make sure to update SSH Slaves Plugin to at least version 1.17 (1.20 recommended).
自 2.60 以来的变更:
  • Fix for NullPointerException while initiating some SSH connections (regression in 2.59). (issue 44120)

  • Restore option value for setting build result to unstable when loading shell and batch build steps from disk. (issue 40894)
  • 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. We strongly recommend you create self-signed certificates yourself and use --httpsKeyStore and related options instead. (issue 25333)

2.32.1 (2016-12-24) 中有什么新内容

自 2.32 以来的变更:
  • Prevent early deallocation of process references by Garbage Collector when starting a remote process. It was sometimes causing build failures with messages like FATAL: Invalid object ID 184 iuota=187 and java.lang.Exception: Object was recently deallocated. (issue 23271)
