 until 1.0, minor versions may contain breaking changes.
 
+## [v202611-00022] – 2026-11-11
+
+### Added
+
+- **Theme "Tintenblau"** (dark: ink blue with cream text; light: paper with dark ink), from the
+  Tintenblau desktop theme; also in the terminal client.
+
+## [v202611-00021] – 2026-11-11
+
+### Added
+
+- **Commits of agents name the model:** every `git commit` an agent makes gets the trailer
+  `Co-Authored-By: <model> (<provider>) via CodeCraft` (a git wrapper in the agent shell, also in
+  the sandbox; your own commits stay unchanged). The text is set under *Settings → General*
+  (`server.commit_trailer`, `{model}`, `{provider}`, `{model_id}`; empty = off).
+
+## [v202611-00020] – 2026-11-11
+
+### Added
+
+- **Reverse engineering outside craft:** *Settings → Agents & commands* can give any mode the
+  `binary_info` and `decompile` (Ghidra) tools; the clean-room rule stays a craft rule.
+- **Raw firmware in `decompile`:** optional `processor` (Ghidra language id, e.g.
+  `ARM:LE:32:Cortex`) and `base_address` for images without a file format (.bin, converted .hex).
+- **Skill "reverse-engineering":** how to identify, decompile and explore programs and firmware
+  (processor table for common chips, HEX conversion, notes in `analysis/`).
+
+## [v202611-00019] – 2026-11-11
+
+### Added
+
+- **Search in a chat:** the magnifier in the chat's top bar searches all of it (messages, tool
+  output) on the server; a hit loads its part of the chat and marks the message.
+- **Media of a chat:** *⋯ → Media* shows every image, video and audio file of the chat and its
+  subagents – generated images, screenshots, files the agent wrote, media in answers, your
+  attachments – filterable, large view, "show in chat" jumps to the message.
+
+### Changed
+
+- **Long chats stay fast:** a chat opens with its messages since the last summary (at most 200);
+  older ones load when scrolling up, the history before a summary on request. Finished turns
+  fold into one line ("42 steps · 3 files", the answer stays visible). Typing, streaming and
+  status changes no longer re-render the whole history, and tool output is only built when a
+  card is opened. Measured with a chat of 5,900 messages: opening 9 s → 0.7 s (phone-like
+  CPU: 22 s → 1 s), typing 440 ms → 25 ms per key.
+
+## [v202611-00018] – 2026-11-10
+
+### Added
+
+- **Enforced reviews:** when a review is configured for a mode, every todo the agent marks
+  completed is reviewed; with findings the todo is reopened and the agent has to fix them and
+  complete it again (up to the configured rounds per todo). Ending the turn with open todos sends
+  the agent back to work as long as it makes progress – for unattended runs, e.g. overnight
+  (such modes may take up to 2,000 steps per turn). The chat shows passed reviews and these
+  reminders; *Settings → Modes* can switch it off per mode (then only one review at the end of a
+  turn, as before).
+- **Max input per model:** providers that limit the input below the context window (e.g. 272k of
+  400k) are taken into account; fetched from the model catalogue, editable in the provider settings.
+
+### Fixed
+
+- **Context overflow instead of compaction** (e.g. DeepSeek V4.1 Flash with 384k max output):
+  requests asked for the model's full max output, and providers count input + output against the
+  window, so long chats failed before automatic compaction kicked in. The output budget is now what
+  the window leaves, the chat is compacted when no reasonable room for an answer is left, and a
+  "context too long" error compacts and retries once instead of stopping. A turn that hits the
+  step limit now says so.
+
+## [v202611-00017] – 2026-11-10
+
+### Added
+
+- **Markdown in your messages:** your messages are shown formatted like the model's answers
+  (headings, lists, tables, code blocks, quotes, bold/italic); single line breaks stay as typed.
+  The eye button next to the text field shows a preview of the formatted message before sending.
+
+## [v202611-00016] – 2026-11-10
+
+### Fixed
+
+- **Phone: page stayed shifted after the keyboard closed** – the top bar (menu) was out of
+  reach. On Android the keyboard now shrinks the page instead of shifting it
+  (`interactive-widget=resizes-content`; the chat stays at its latest message); browsers that
+  still shift the page (iOS Safari) get it scrolled back once the keyboard closes.
+
+## [v202611-00015] – 2026-11-10
+
+### Fixed
+
+- **Generated images missing on other devices:** when an agent moved or renamed a generated
+  image afterwards (e.g. sorted it into subfolders), the gallery pointed to the old file – only
+  the device that had it in its browser cache still showed it. Now:
+  - generated images are also kept in the image store and shown from there when the file is gone
+    (existing images get their copy on the first start);
+  - their entries follow moves and renames: after an agent's `mv`/`rename`, when moved with the
+    file manager, and on the next view (found by file name, or by content when renamed);
+  - in the chat, an image that cannot be found falls back to the preview the model saw.
+
+## [v202611-00014] – 2026-11-10
+
+### Added
+
+- **New folder in the folder picker:** creating an automation or a chat, *New folder* creates a
+  subfolder of the shown folder and selects it.
+
+## [v202611-00013] – 2026-11-10
+
+### Added
+
+- **Automation editor:** *New automation* asks for name, project and a starting point (blank
+  example structure or a template), creates `.codecraft/jobs/<name>.md` and opens an editor:
+  the instructions in a Markdown editor, schedule and settings next to them, and an assistant
+  chat in which a model works out the instructions with you and edits the file (reloaded after
+  each answer). New automations start switched off.
+- **Graphical schedule:** every few minutes, hourly, daily, on weekdays, monthly or a cron
+  expression, with the next runs in server time.
+- **Chat list:** folders and projects can be dragged into any order or moved and pinned to the
+  top via their menu; the order is kept per user on all devices. A new message moves the chat
+  to the top of its folder or project, no longer the whole project.
+
+### Changed
+
+- **Automation files hold only the instructions;** name, schedule, mode, model, approval mode
+  and time limit are settings of the automation. Existing job files are taken over on the first
+  start (settings into the database, the frontmatter removed from the file). Registering a
+  plain Markdown file creates a switched-off automation to be scheduled in the editor.
+
+## [v202611-00012] – 2026-11-10
+
+### Added
+
+- **Approval mode of automations in the list:** *Automations* shows the approval mode of each
+  automation as a selection; the change is written into the job file and applies from the next
+  run. "Allow everything" lets nightly runs work without waiting for approvals (they used to
+  wait for an answer via Telegram until the timeout).
+- **Telegram per chat:** *⋯ → Send questions to Telegram* (shown with a paired bot) decides
+  whether approvals and questions of that chat and its subagents are sent to Telegram. New chats
+  from the web UI and automation runs start with it switched off (they stay in the web UI);
+  chats started from Telegram and existing chats keep reporting. The chat currently open in
+  Telegram always reports.
+
+## [v202611-00011] – 2026-11-09
+
+### Added
+
+- **Collapsible task list:** the model's task list above the composer folds to one line
+  (progress and current task) with a click on its heading; the choice is kept per device.
+- **Square and short screens** (e.g. Clicks Communicator, phones in landscape): tighter top bar,
+  composer and new-chat wizard, so the chat keeps most of the height.
+
+### Fixed
+
+- **Blank page on phones after the update:** installed apps (PWA) checked their service worker
+  at its old URL, got the web page instead of a script and therefore kept the previous app
+  version forever. With the new image format of v202611-00010 that old version crashed after
+  showing the chat for a moment. Old service worker URLs now get the clean-up worker, which
+  removes the stale worker and reloads the current version. Missing scripts/styles answer
+  404 instead of the web page.
+
+## [v202611-00010] – 2026-11-09
+
+### Changed
+
+- **Chats with many images load much faster:** images (screenshots, generated images, pasted
+  images) are stored separately instead of inside the messages and load on demand when they
+  scroll into view, cached by the browser. Large PNGs without transparency are stored as JPEG.
+  Older chats are converted once on the first start; the database usually shrinks a lot.
+  Example: a chat with 120 screenshots loads 1.5 MB instead of 66 MB.
+- **Compressed responses:** the API and the web UI are sent with gzip/brotli (not images,
+  downloads or live streams).
+
+## [v202611-00009] – 2026-11-09
+
+### Fixed
+
+- **Sandbox on x86_64:** the start-up check of bubblewrap did not mount `/lib64`, so it failed
+  on amd64 hosts and shell commands of non-admin users were disabled.
+
+## [v202611-00008] – 2026-11-09
+
+### Added
+
+- **Instructions per chat:** *⋯ → Instructions for this chat* (Telegram: `/prompt`) sets rules
+  that apply to every message of that chat on top of the mode – language, tone, the part of the
+  project to work on. A chip in the header shows when a chat has them; forks keep them.
+
+### Fixed
+
+- OpenAI-compatible providers: tool results no longer carry a `name` field. Gateways that
+  translate to Anthropic (opencode) rejected the request with "anthropic-messages cannot
+  preserve named conversation participants".
+- Telegram: the token field is no longer filled in by the browser's password manager, the bot
+  token is found in whatever is pasted (also the whole BotFather message), and a wrong format
+  gets a clear message instead of "HTTP 404".
+

+name: reverse-engineering
+description: Analyse programs and firmware – identify the format, inspect with binary_info, decompile with Ghidra (decompile tool, also raw firmware with processor/base address), explore the output and write down findings. For file formats, protocols, bugs and interoperability.
+---
+# Reverse engineering of programs and firmware
+
+You analyse a binary to understand how it works – a file format, a protocol, an algorithm,
+a bug, or how to talk to a device. Work from cheap to expensive and write down what you learn.
+
+Only analyse binaries the user owns or may analyse (their own builds, their devices, programs
+for interoperability). Decompiled code is third-party material: never commit it and never paste
+it into the user's source – describe behaviour in your own words.
+
+## 1. Identify
+- `file <path>` – format, architecture, stripped or not.
+- Executables and libraries (PE .exe/.dll, ELF, Mach-O): `binary_info` – sections, imports,
+  exports, strings. Imports and strings tell a lot (file names, error messages, protocol
+  keywords, library names) before any decompiling.
+- Archives and update packages: unpack first (`unzip`, `7z x`), then identify the parts.
+- Intel HEX / S-record firmware: convert to a raw image –
+  `objcopy -I ihex -O binary fw.hex fw.bin` (the lowest address in the HEX file is the base
+  address). An ELF from the firmware's build (e.g. `zephyr.elf`, `firmware.elf`) is far better
+  than a raw image: symbols and addresses are included – look for it first.
+- Raw images: look for clues with `strings -n 6 fw.bin | head -200` and
+  `python3 -c` one-liners (vector table, magic numbers, embedded file systems).
+
+## 2. Raw firmware: processor and load address
+`decompile` needs both for images without a file format:
+
+| Chip family | `processor` | typical `base_address` |
+|---|---|---|
+| ARM Cortex-M (STM32, nRF52, RP2040, SAMD) | `ARM:LE:32:Cortex` | STM32 `0x08000000`, nRF52 `0x00000000`, RP2040 `0x10000000` |
+| ARM Cortex-A / ARMv7 | `ARM:LE:32:v7` | from the bootloader / datasheet |
+| AArch64 | `AARCH64:LE:64:v8A` | |
+| ESP32 (Xtensa) | `Xtensa:LE:32:default` | per segment (use the ELF if possible) |
+| AVR (Arduino) | `AVR8:LE:16:atmega256` or `AVR8:LE:16:default` | `0x0` |
+| MIPS (routers) | `MIPS:BE:32:default` or `MIPS:LE:32:default` | e.g. `0x80000000` |
+
+Cortex-M check: the first word of the image is the initial stack pointer (0x2000xxxx = RAM),
+the second the reset vector – it points just behind the base address. If the decompiled output
+is mostly garbage, the processor or base address is wrong: fix it and run again (results are
+cached per file *and* processor/address).
+
+## 3. Decompile
+- `decompile` with the path (plus `processor`/`base_address` for raw images). Large programs:
+  start with `max_functions` (e.g. 2000), widen when needed.
+- Output in `.codecraft/decompiled/<name>/`: `functions.tsv` (address, name, size, file,
+  signature), `functions/*.c`, `strings.tsv`, `imports.tsv`, `exports.tsv`.
+
+## 4. Explore
+- Start from what you know: a string, an import or an export.
+  `grep -l "SetCommState" .codecraft/decompiled/<name>/functions` finds the functions that use it.
+- Follow the calls by reading the functions; note addresses (`FUN_00401a30`) as you go.
+- Broad searches through thousands of functions: delegate them to an `explore` subagent with a
+  precise question and let it report file:line.
+- File formats: compare the reading/writing code with a sample file (`python3` to dump the bytes)
+  until every field is explained.
+
+## 5. Write it down
+Keep findings in `analysis/notes.md` (create it; it is not committed): structure of the
+program, important functions with addresses, data structures, file formats and protocols with
+field tables, open questions. Make sure `.gitignore` excludes `analysis/`, `original/` and
+`.codecraft/decompiled/`. At the end, report what you found and how sure you are – mark guesses
+as guesses.
