 All notable changes to CodeCraft. Versions follow [Semantic Versioning](https://semver.org/);
 until 1.0, minor versions may contain breaking changes.

+## [v202611-00031] – 2026-11-15
+
+### Fixed
+
+- Images read by an agent (Read tool) are shown right away; with Claude Code they were dropped.
+
+## [v202611-00030] – 2026-11-15
+
+### Added
+
+- **`/clear`**: the model forgets the conversation so far; the chat keeps showing it, a divider marks
+  the cut. Also starts a fresh session with Claude Code.
+
+## [v202611-00029] – 2026-11-15
+
+### Added
+
+- **Statistics**: sections and models fold; long history with a year filter (monthly bars for long
+  ranges); export of the shown figures as XLSX (all tables) or CSV (one table).
+- **Prompt snippets**: own text blocks, inserted with `/name` in the message field (Settings → Account).
+- **Read-only links**: share a chat's text with people without an account (valid 1–90 days, revocable).
+- **Git panel**: the small model suggests a commit message for the staged changes.
+- **Weekly review** as a push notification (Mondays 08:00: chats, checks, costs; opt-in).
+- **Speech-to-text on the server** (`server.transcribe_model`) for browsers without dictation (Firefox).
+- **Offline**: the chat list and the last opened chats stay readable without a connection.
+- **Planning model** setting: plan mode always uses it, other modes the chat's model.
+- **Automations** send their report as a push notification when a run ends (switchable).
+
+### Fixed
+
+- fal.ai: the provider check no longer reports "API key rejected" when only the model listing is not offered.
+
