  • Latest News

    • End of life operating systems:

      • Beginning with Jenkins 2.407, Jenkins administrators will be warned if they are running Jenkins on an operating system that is within 6 months of its end of life date.

      • The operating system end of life warning has been backported to Jenkins 2.401.2 after discussion in the Jenkins developer mailing list.

      • The Jenkins project does not test Jenkins on operating systems that are not supported by the operating system provider.

      • We don’t support Jenkins on operating systems that are not supported by the operating system provider.

      • These last months, we’ve seen OS vendors offer extended support contracts for their systems having reached their end of life. However, the Jenkins project has not extended its Linux support policy or its Windows support policy beyond the public end of life for any of those operating systems.

    • Java 17 instructions

      • Jenkins is transitioning from using Java 11 as the preferred version to using Java 17, which offers more functionality, speed, and development support.

      • The documentation and usage areas are being updated to reflect this change, while also clarifying that Java 11 support in Jenkins will continue.

Documentation Update

Contributed by: Kevin Martens

Over the course of July, six different blog posts were published from nine different authors, including updates on the Google Summer of Code projects that are in progress. Thanks to all the participants for their insights and work!

The Jenkins documentation has transitioned to using Java 17 within the installation guides and other documentation areas. This issue explains some more background of the transition and what work has been completed already. A blog post was published to highlight this change and provide background for the transition. The post also encourages users to upgrade so that they can enjoy the additional features and functions that come with Java 17.

Outreach and advocacy Update

Contributed by: Alyssa Tong

Google Summer of Code projects midterm evaluations are complete!

The midterm demos were presented via the Jenkins online meetup at the beginning of July, 2023. If you missed it, refer to the blog post for the recap.

Congratulations to all four GSoC Contributors for passing this milestone!

Onward to the second half of GSoC 2023.

Happy coding!
