 All notable changes to CodeCraft. Versions follow [Semantic Versioning](https://semver.org/);
 until 1.0, minor versions may contain breaking changes.
 
+## [v202611-00040] – 2026-11-15
+
+### Fixed
+
+- **Images you upload reach Claude Code**: its chats read the history without the image bytes, so the
+  files it was pointed to were empty. Images without data are no longer written as empty files.
+
+## [v202611-00039] – 2026-11-15
+
+### Changed
+
+- A chat's colour no longer tints the chat background (pane, message field, agent bubbles, top bar
+  fill); it still marks the top bar line, the list entry, the badge and your own bubbles.
+
+### Fixed
+
+- **Claude Code can ask questions again**: its `AskUserQuestion` was always rejected; now the question
+  appears as a question card in the chat (single and multiple choice) and the answers go back to it.
+
+## [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
