+## [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
