+## [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.
