Description

Realign the server-versions job in .github/workflows/linux.yml with the
supported-version policy — the 3 latest series + the last 2 LTS series + head
after the 26.8 LTS release.

Action Version Reason
Add 26.8 newest release, and newest LTS
Keep 26.7, 26.6 still in the 3 latest series
Keep 26.3 second-newest LTS
Keep head nightly build of ClickHouse master
Remove 26.5 no longer one of the 3 latest series
Remove 25.8 no longer one of the 2 newest LTS series

26.8 is at the same time the newest release and an LTS, so the numeric set has
4 entries, not 5.

Changes

  • .github/workflows/linux.ymlserver-versions matrix:
    25.8, 26.3, 26.5, 26.6, 26.7, head -> 26.3, 26.6, 26.7, 26.8, head.
    Trailing # LTS / # Stable comments kept in sync.

Test

  • CI-only maintenance change. There is no client-code change, therefore no new
    test, no CHANGELOG entry, and no version bump.
  • .github/workflows/linux.yml parses as valid YAML and the job matrix reads as
    ['26.3', '26.6', '26.7', '26.8', 'head'].
  • The new image tag exists: docker manifest inspect clickhouse/clickhouse-server:26.8-alpine succeeds.
  • The ci/docker-compose.yml default pin (25.12-alpine) is unrelated to the
    removed versions and is left unchanged.

Realign the server-versions job with the supported-version policy
(3 latest series + last 2 LTS series + head) after the 26.8 LTS release.

Add 26.8 (newest release and newest LTS). Drop 25.8 (no longer one of the
two newest LTS series) and 26.5 (no longer one of the three latest series).
26.8 is both the newest release and an LTS, so the numeric set is 4 entries.

CI-only change: no client behaviour changes.
