Summary

Publishes the Calico Enterprise 3.21.9 hotfix release docs (modeled on #2747, the 3.21.8 publish). Limited to the release-metadata + release-notes files — none of the API-reference changes from the reference PR.

Changes (calico-enterprise_versioned_docs/version-3.21-2/)

  • releases.json — new v3.21.9 release block prepended. All tigera/* component versions at v3.21.9; tigera-operator at v1.38.16.
  • variables.jsreleaseTitle, filesUrl, chart_version_name bumped to v3.21.9.
  • release-notes/index.mdx — new 3.21.9 hotfix release section, dated June 18, 2026, Bug fixes: Security updates.

Notes for reviewers

  • v3.21.9 is not yet tagged in tigera/calico-private, and v1.38.16 is not yet tagged in tigera/operator (latest is v1.38.15) — both versions are set per the planned hotfix. Operator v1.38.16 was specified explicitly.
  • Third-party component versions (coreos-, eck-, upstream-istio) mirror 3.21.8 since 3.21.9 is not cut; update if the hotfix bumps any dependency.

- releases.json: add the v3.21.9 release block (all tigera component
  versions at v3.21.9; tigera-operator v1.38.16). Third-party component
  versions mirror v3.21.8 (3.21.9 not yet tagged in calico-private).
- variables.js: bump releaseTitle, filesUrl, chart_version_name to v3.21.9.
- release-notes/index.mdx: add the 3.21.9 hotfix section (June 18, 2026),
  Bug fixes: Security updates.
