+## Standing notes
+- impress-frontend, impress-backend (used for both backend + celery services), impress-y-provider all
+  share the same version tag from the suitenumerique/docs monorepo. Upgrade all four in lockstep.
+- AUTO_MIGRATIONS=true means DB migrations run automatically on backend startup. No manual step needed.
+- Minio tag uses a date-based RELEASE.YYYY-MM-DDTHH-MM-SSZ format — abra cannot parse it for upgrades;
+  check manually on https://github.com/minio/minio/releases.
+- v5.2.0 adds two optional new env vars: DOCUMENT_ALL_ENDPOINT_ENABLED and OIDC_OP_USER_ENDPOINT_FORMAT.
+  Both are backward-compatible (no action required for existing deployments).
+- Recipe version label convention: 0.X.Y+vA.B.C where A.B.C is the impress version.
