 # Changelog - FlowDeck
 
+## v5.11.0 (2026-09-11) — FlowDeck Agent : UX chat améliorée
+
+> Quatre améliorations majeures du panneau Agent (v4.10.0 → v4.14.0) pour
+> une expérience plus proche de Notion AI.
+
+- **Auto-titre à chaque requête** — Le titre de la conversation se met à jour
+  après chaque échange avec l'IA (pas seulement à la création). Il reflète
+  le sujet courant et rend l'historique facile à parcourir.
+- **Aperçu au survol / appui long** — Dans l'onglet Historique, un survol
+  souris (desktop) ou un appui long (mobile) ouvre un pop-up avec le premier
+  message utilisateur et la dernière réponse de l'agent, sans quitter la liste.
+- **Normalisation des blocs `write_blocks`** — L'outil tolère désormais les
+  erreurs fréquentes du LLM : `text`→`content`, `heading`→`heading_1`…`heading_4`,
+  `bullet/list`→`bulleted_list`, génération d'ID, types inconnus→paragraphe.
+  Le script PowerShell (ou tout code) s'écrit correctement dans un bloc `code`.
+- **Accordéon style Notion** — Le raisonnement de l'agent s'affiche dans un
+  composant pliable : « Pensées » (chevron, contenu complet au clic) et
+  « Actions » (lignes simples, passé, non-cliquables). Le tout reste visible
+  en permanence sous la réponse, sans encombrer l'écran.
+- **Tests** — `test_write_blocks_normalizes_llm_blocks`,
+  `test_engine_titles_conversation_on_each_request`,
+  `test_suggest_title_strips_composer_prefixes`.
+
 ## v5.9.0 (2026-09-10) — AI Writing Assist (éditeur)

 - **Pages** : le contenu est organisé en blocs (paragraphes, titres, listes, to-do, tableaux, images, formules, bases embarquées). La barre latérale liste les pages récentes, favoris, agents, partagées et publiées.
 - **Documents & espaces de travail** : un « document » est une page éditeur (type Notion) qui vit dans un espace de travail. Pour créer un document dans un espace : appelle `read_workspaces` (reprends le `workspace_name` ou l'id exact), puis `create_document`. Pour modifier un document existant : `read_document` puis `write_blocks` (blocs et/ou titre). Pour supprimer : `delete_document` (corbeille). `search_workspace` retrouve aussi les documents et les espaces par titre.
+- **Format des blocs** (pour `write_blocks`) : chaque bloc est un objet `{"type": "...", "content": "texte"}`. Le champ du texte s'appelle **`content`** (jamais `text`). Un script / code s'écrit dans un bloc `{"type": "code", "content": "...", "language": "powershell"}`. Les titres sont `heading_1`, `heading_2`, `heading_3`, `heading_4`. Autres types : paragraph, bulleted_list, numbered_list, to_do, quote, divider, toggle, callout.
 - **Collections (bases de données)** : des ensembles de pages structurées avec des propriétés (texte, nombre, sélection, dates…). Chaque collection peut avoir plusieurs vues : tableau, board (kanban), calendrier, galerie, liste, timeline, graphique, formulaire, carte, flux, gantt. Ajouter une propriété ou une vue = outils add_property / create_view.
 - **Créer du contenu** : « crée une collection X », « crée une page », « ajoute une propriété Statut à la collection Y » sont des actions que l'agent peut exécuter directement avec ses outils.
 - **Espaces de travail** : FlowDeck gère des espaces locaux et des dépôts Gitea/GitHub (pages privées dans un dépôt, issues reliées via read_gitea_issues). On change d'espace depuis le menu en bas à gauche (« Switch workspace »).
