Red Hat Build of Keycloak 26.6 Full Support End: November 15, 2026, and 26.4 End of Life

By Scott Bissett  ·  Published: October 20, 2026  ·  Reference guide  ·  Dates read twice on the day of publication, from Red Hat's Product Life Cycle Data API and the rendered Product Life Cycles page at access.redhat.com, and re-checked at every site build; phase definitions from Red Hat's Red Hat build of Keycloak Life Cycle and Support Policies page.

Red Hat ends Full Support for Red Hat build of Keycloak 26.6 on November 15, 2026, and Maintenance Support for 26.4 on December 3, 2026. The two dates are three weeks apart and mean different things. For 26.6, the November date is a step down: it moves from Full Support to Maintenance Support, which runs until May 15, 2027. For 26.4, the December date is the end: it has been in Maintenance Support since June 3, 2026, and Red Hat lists no phase after it. Live status and EOL Risk Score are on the 26.6 and 26.4 pages; every version is on the Red Hat build of Keycloak page.

The dates, as Red Hat prints them

These rows come from the Red Hat build of Keycloak entry in Red Hat's product life cycle data.

In the table, 26.4's Full Support ended the day 26.6 became generally available, and 26.2's Maintenance Support ended the same day.

What Red Hat's policy says

Red Hat's Red Hat build of Keycloak Life Cycle and Support Policies set out the rules behind the dates:

• Minor releases: a minor release is supported with maintenance updates, meaning bug fixes and qualified security patches, until a second subsequent minor release is available, so for approximately twelve months.
• Major versions: from 26.x, a major version indicates a support life cycle of a minimum of two years (for 26.x) or three years (for 27.x and onwards).
• Full Support: provided under the published Scope of Coverage and Service Level Agreement; in this phase minor versions are the primary source of enhancements and new features.
• Maintenance Support: qualified security patches of Critical or Important impact, as well as select mission-critical bug fixes, are released.

Red Hat's life cycle table lists no version newer than 26.6 today, so this guide does not name one; the table already dates 26.6's move from Full to Maintenance Support.

What to do

1. On 26.4: upgrade to 26.6, the newest release Red Hat lists, before December 3, 2026. Check Red Hat's upgrading guide for the steps from your release.
2. On 26.6: nothing stops on November 15, 2026 except the move from Full to Maintenance Support. Plan the next minor upgrade before May 15, 2027.
3. On 26.2 or older: already out of maintenance; 26.2 ended on June 3, 2026.
4. Check other versions: the Red Hat build of Keycloak page re-reads Red Hat's data, and the EOL Checker answers for a single version.
