 # Changelog — FlowDeck
 
-## v5.1.0 (2026-09-06) — Database Avancée : inline DB, templates prédéfinis & validation
+## v5.1.1 (2026-09-07) — Rendu Markdown naturel (éditeur + panneau Agent)
+
+> L'agent FlowDeck et l'insertion dans les pages affichent désormais le markdown
+> rendu (titre, gras, tableaux, code…) au lieu des caractères bruts `##`, `**`…
+
+### Éditeur de page (blocs)
+- **Insertion agent → vrais blocs** : `applyAIBlocks()` (et le mode *replace* de
+  `fdApplyDocument`) convertit la réponse markdown en blocs réels via `md2b()` :
+  `## titre` → bloc `heading_2`, tableaux GFM → bloc `table`, ` ``` ` → bloc `code`,
+  listes `-`/`1.`, to-do, citations, séparateurs. Plus de `## ` affiché littéralement.
+- **Rendu inline** : les blocs de texte affichent désormais le markdown inline
+  (gras `**`, italique `*`, code `` ` ``, lien `[t](url)`, barré `~~`) sans les
+  caractères, via `mdEsc()` dans `renderBlock` (paragraphes, titres, listes, to-do,
+  toggle, citation, callout, code).
+- Les raccourcis clavier markdown existants (`# ` + espace → H1…) restent inchangés.
+
+### Panneau FlowDeck Agent
+- **`renderMarkdown()`** (agent_panel.html) : les réponses de l'agent s'affichent en
+  HTML rendu — titres H1–H4, tableaux (GFM), blocs de code, listes à puces/numérotées
+  (+ cases), citations, séparateurs, gras/italique/code/lien/barré. HTML échappé
+  avant rendu (sécurité face au contenu LLM). CSS dédié (`.fd-md-*`, `pre`, tableaux).
+- Le bouton « Insérer dans la page ouverte » continue d'utiliser `fdApplyDocument`
+  (maintenant → blocs réels).
+
+### Tests / validation
+- 271 tests pytest verts (aucune régression). Rendu markdown vérifié fonctionnellement
+  en Node (titres, tableau, code, listes) ; éditeur et panneau rendus 200 avec les
+  nouveaux composants présents.
