2026-02-19: UBI Tag missing for Monthly Release 18.9

UBI Tag missing for Monthly Release 18.9 (Severity 3)

Problem: The monthly release 18.9 was missing the correct UBI tag (v18.9.0-ubi), which prevented the expected build pipeline from running.

Impact: The correct CNG UBI build for the monthly release 18.9 was not initially created, potentially delaying the release until the tag issue was fixed.

Causes: An old monthly release pipeline referenced a deleted feature flag, causing the release tooling to create the incorrect tag v18.9.0-ubi8 instead of the expected v18.9.0-ubi.

Response strategy: We recreated the deleted feature flag and retried the tagging job, which successfully created the correct tag and triggered the associated build pipeline.
