Attending: Mark Waite, Robson Camaducci, Kris Stern

Agenda

- Windows Server 2019 end of support in Jenkins container images
  - Jenkins core container stopped support in [Jenkins 2.568.1](https://github.com/jenkinsci/docker/releases/tag/2.568.1) ([changelog](https://www.jenkins.io/changelog/2.568.1/) and [upgrade guide](https://www.jenkins.io/doc/upgrade-guide/2.568/#upgrading-to-jenkins-lts-2-568-1))
  - Jenkins agent (inbound and ssh) containers stopped support in Jenkins [2.579](https://www.jenkins.io/changelog/2.579/) and 2.568.3

- LTS updates
  - New LTS release: 2.568.3 - 2 Sep 2026

- [Jakarta EE 10](https://jakarta.ee/release/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, may not happen until 2027

- Operating system update for s390x
  - Mark Waite updated from Ubuntu 22.04 to Ubuntu 26.04
    - Acceptance tests for installers enabled again

- Java upgrade campaign is moving from quarterly to monthly
  - Quarterly critical patch update (like July 2026 - JDK 25.0.4)
  - Monthly security critical patch update (like August 2026 - 25.0.4.1 and September 2026 25.0.4.2)
  - Oracle and Eclipse Temurin have switched
    - AI detection of security issues needs an increased pace of security fixes

  - Eclipse Temurin builds for s390x are not available as soon as x64 and aarch64
    - May result in Jenkins container images splitting their delivered JDK by platform

- Java 25 support
  - 243 of the top 250 actively maintained plugins are testing with Java 25
  - No reports of issues specific to Java 25

- Work in progress
  - Controller [pull requests](https://github.com/jenkinsci/docker/pulls)
  - Inbound agent [pull requests](https://github.com/jenkinsci/docker-agents/pulls)
  - SSH agent [pull requests](https://github.com/jenkinsci/docker-ssh-agent/pulls)
