Agenda

  • Windows 2019 end of support in Jenkins container images
    • Jenkins core container stopped support in Jenkins 2.568.1 (changelog and upgrade guide)
    • Inbound agent container - too expensive to maintain and unstable
      • Kubernetes platforms dropped Windows 2019 support already
      • Users can use the final agent version or build their own agent container image
      • Windows 2022 and Windows 2025 support will continue
    • SSH agent container
      • Kubernetes platforms dropped Windows 2019 support already
    • Damien will propose two pull requests that propose the change
      • Happy to have help on the blog post, willing to do it himself if needed
    • Want to drop support in August, possibly after a final release
  • When do we drop Java 17 support in the agent container images?
    • Proposed to do it soon because Java 17 controllers have known vulnerabilities
  • LTS updates
    • New LTS release: 2.568.2 - 5 Aug 2026
  • Jakarta EE 10 support
    • Breaking change with removal of HttpServerContext, need to adapt to that change in Jenkins core
    • Pull requests not yet submitted for Jenkins core and related components
    • Goal is to update to Jakarta EE 10 during calendar 2026
  • Container image updates for the Jenkins controller
    • Windows Server 2019 dropped from weekly and LTS
    • Windows Server 2025 added to weekly and LTS
  • Operating system update for s390x
    • No current processes depend on s390x
    • Mark Waite to update from Ubuntu 22.04 to Ubuntu 24.04 or later
      • Check if Docker works on Ubuntu 24.04, if it works, re-enable acceptance tests for installers
  • Java upgrade campaign is in progress
    • Waiting for Temurin builds to be available for Java 8, 11, 17, 21, and 25 for infrastructure and Java 17, 21, and 25 for container images
  • Work in progress
