+- **Coffre Secrets — Phase 1** (contenu de la release 2.80.0, dont l'entrée changelog manquait) : chiffrement par enveloppe AES-256-GCM, API `/api/coffres`, nœud virtuel Secrets sous le Home de l'utilisateur.
+
+### Corrigé
+
+- **Étiquette de version 2.80.0** — le tag v2.80.0 pointait sur un contenu dont le fichier `VERSION` valait encore 2.79.0 (un merge ne déclenche pas le bump automatique) ; `VERSION` et tous les fichiers dérivés passent à 2.80.1, pour que la version affichée corresponde au tag de la prochaine release.
+- **CI lint (ruff)** — 60 erreurs corrigées dans `backend/` : alias `datetime.UTC` (Python 3.11+), `TimeoutError` natif, tri d'imports et import inutilisé dans `coffre_store.py`, `.encode()` sans argument redondant, `fromisoformat` gérant « Z » ; aucune règle ruff masquée, aucun changement de comportement.
