 ## Standing notes
+  - **2026-08-28 re-check** (endoflife.date/api/mattermost.json 2026-08-28; Docker Hub; GitHub
+    releases): **11.7.10** (released 2026-08-26, "various bug fixes", not prerelease) is the newest
+    11.7.x ESR patch — the ESR/LTS line has NOT moved, still **11.7** (EOL **2027-05-15**). This run
+    bumps open PR #2 **11.7.9 → 11.7.10** (ESR patch within the same line). 11.8/11.9/11.10 remain
+    innovation releases (EOL 2026-09-15 / 10-15 / 11-15), NOT ESR — do NOT target; 10.12 expired.
+    postgres **15-alpine HELD** (DB-major 16/17/18 out of scope, plain-postgres recipe w/o
+    pgautoupgrade: operator dump/restore needed). git.autonomic.zone mirror main reconciled to
+    coopcloud (86e0d0b5 = 10.11.22, upstream still pins the EXPIRED 10.11 ESR).

   concept in Mattermost is **ESR**; there is NO "10.x LTS line". Release calendar (endoflife.date/mattermost):
   - **10.11** = previous ESR, security support **ends 2026-08-15** (~7 weeks) — migrated away 2026-06-19
