The Chinese localization of Jenkins continues to be available, but the links to the Chinese website have been removed.

  • Prototyping Azure arm64 build agents is done, we can move forward to production for our internal usages first.

User Experience Update

Contributed by: Mark Waite

An accessibility assessment of Jenkins has been provided by Deutsche Telekom. The assessment is being used by Cristina Pizzagalli and others to improve the Jenkins user experience for users with disabilities. Contributors that are interested in helping with the accessibility improvements should include their comments on JENKINS-71153.

Mobile users of Jenkins will now see a card layout of the Jenkins user interface, thanks to work done by Jan Faracik.

The Prototype.js JavaScript library that is widely used in Jenkins core and Jenkins plugins is being replaced. Special thanks to Tim Jacomb, Basil Crow, Alexander Brandes, and several others for their work replacing that library. Contributors that would like to help with the JavaScript work are invited to assign themselves one of the issues listed in JENKINS-70906.

Documentation Update Contributed by: Kevin Martens

Over the course of April, there were 4 blog posts published, featuring seven different authors. Bruno Verachten continues his series on building android apps in Jenkins. As Google Summer of Code begins, we want to acknowledge and thank all of the applicants for their efforts. Thanks to all of the continuing and new contributors, all of your work helps support both the Jenkins project and the Open-Source community.

We also want to thank DigitalOcean for their continued support and sponsorship of Jenkins. They have provided us with an additional $8,400 credit as the Infrastructure team works on reducing bandwidth usage further.

Outreach and advocacy Update

Contributed by: Alyssa Tong

Jenkins in Google Summer of Code (GSoC)

We had an unprecedented number of GSoC applicants interested in Jenkins this year. The Jenkins project received over 60 proposals by the close of the application period. Dedicated Jenkins mentors worked overtime and weekends to review and grade proposals within a two weeks period. Many THANKS to the wonderful Jenkins mentors, this program isn’t possible without them.

Best of luck to all GSoC participants!

Jenkins at cdCon + GitOpsCon

April was all about preparations for cdCon, which took place on May 8–9, 2023 in Vancouver, Canada as cdCon + GitOpsCon, co-organized with the Cloud Native Computing Foundation (CNCF). Members of the Jenkins Governance Board, long-time Jenkins users and contributors Mark Waite and Alexander Brandes were in attendance. Mark took part in the Graduated Projects Keynote Panel, discussing Jenkins Community’s experiences with graduation and sharing his thoughts on why graduation matters for the community and users of Jenkins. Recordings for the conference will be available in approximately two weeks, on the CDF YouTube channel.

Thanks to everyone who attended!
