 All notable changes to CodeCraft. Versions follow [Semantic Versioning](https://semver.org/);
 until 1.0, minor versions may contain breaking changes.
 
+## [v202611-00038] – 2026-11-15
+
+### Changed
+
+- The chat menu in the sidebar has a **Delete** entry (with the question about the chat's own folder);
+  colour and icon selection moved out of it – they remain in the ⋯ menu inside the chat.
+
+## [v202611-00037] – 2026-11-15
+
+### Added
+
+- **Deleting a chat asks about its folder**: if the chat has a folder of its own (inside your folders,
+  not shared with any other chat, no project folder), you can delete it with the chat – with the
+  number of files, size and a warning for git repositories. The server checks again before deleting.
+
+## [v202611-00036] – 2026-11-15
+
+### Added
+
+- **Claude Code gets all CodeCraft tools** (image generation, 3D, OpenSCAD, browser, scheduling,
+  diagnostics, reverse engineering, skills, ask_user, the server's MCP tools …) over an MCP bridge,
+  as `mcp__codecraft__<name>`. Tools the CLI has itself (read, write, edit, bash, grep …) are not
+  offered twice. Calls go through the usual approval cards and rules.
+
+## [v202611-00035] – 2026-11-15
+
+### Fixed
+
+- Creating an SSH key failed with "No user exists for uid 99": `ssh-keygen`, `ssh-keyscan` and
+  `ssh-add` get the same passwd workaround as `ssh`.
+
+## [v202611-00034] – 2026-11-15
+
+### Fixed
+
+- `ssh`, `scp` and `sftp` failed with "No user exists for uid 99" because the container runs as a uid
+  without passwd entry; the image now wraps them with nss_wrapper (also used by the key wrappers).
+
+## [v202611-00033] – 2026-11-15
+
+### Added
+
+- **SSH keys** (Settings → Account): generate (ed25519) or import keys; agents, the terminal and the
+  git panel use them automatically for `ssh`, `scp`, `sftp`, `rsync` and git over ssh. Hosts are
+  trusted on first contact; the public key can be copied for the server's `authorized_keys`.
+
+## [v202611-00032] – 2026-11-15
+
+### Fixed
+
+- Agents now know that git credentials are stored (hosts, no secrets) and no longer search the
+  environment for them; the system prompt explains `git push` just works and how to read the token
+  for REST calls without printing it. Claude Code runs get the user's git credentials and identity too.
+
+## [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.
+

+//! CodeCraft's tools for the Claude Code CLI, as an MCP server (streamable HTTP, JSON answers).
+//!
+//! The CLI only knows its own tools. For every run the server registers a secret token and
+//! passes `--mcp-config` with `http://127.0.0.1:<port>/api/mcp-bridge/<token>`; the CLI then
+//! lists and calls the tools like any MCP tool (`mcp__codecraft__<name>`). The token is the
+//! credential (the route is public) and binds the calls to the chat that started the run.
+//! Permissions are asked by the CLI through the usual `can_use_tool` request, so the approval
+//! cards, rules and project approvals work as for the CLI's own tools.
