[Initial Message] 02 March 2026, starting at 09:00 UTC, the Jenkins controllers and agents on release.ci.jenkins.io will be upgraded to use JDK25 at runtime instead of JDK21.
This operation will require controller restarts and agent reconnections. A short service disruption is expected during the maintenance window.
