The Hazelcast library used for peer-to-peer communications in High Availability (HA) controllers will be upgraded from version 5.6.0 to 5.7.0 in the July 2026 CloudBees CI release.
Since Hazelcast Community Edition does not support members of different minor versions sharing a cluster, a regular rolling upgrade across this change is not possible.
If you are running an HA controller on any previous version, the upgrade should be automatic, although there will be a temporary outage similar to upgrading a non-High Availability (HA) controller.
Blue Ocean end-of-life
Starting with the July 2026 CloudBees CI on traditional platforms release, Blue Ocean will reach end-of-life (EOL) and will no longer be supported.
After this date, Blue Ocean will not receive updates, security patches, or technical support and will be removed from the CloudBees Assurance Program (CAP).
What this means for you:
Blue Ocean may continue to work, but is no longer supported by CloudBees.
No further updates or security patches will be provided.
Technical support for Blue Ocean will no longer be available.
