Eliya — Lifecycle & Support

Eliya publishes the latest LTS. JDK 21 is not a published target — anyone needing JDK 21 in production today is already on an established vendor distribution (Corretto, Temurin, Zulu). Eliya will become multi-version naturally when JDK 29 LTS lands in September 2027.

Quarterly CPU calendar

OpenJDK publishes Critical Patch Updates on the third Tuesday of January, April, July, and October. Eliya targets publication within two weeks of each upstream release. Out-of-cycle CVE-triggered rebuilds target one week.

What changes between CPUs

Each quarterly release includes:

All upstream OpenJDK security fixes and stability patches for the quarter.
Refreshed java.security hardening if upstream defaults have changed.
No behavioural changes to -XX:+UseEliyaDefaults unless explicitly noted in CHANGELOG.
No API changes — strictly CPU semantics.
