 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.
