# Feature Release

### **(v0.237.010)**
### **(v0.237.011)**

#### Bug Fixes

* **Chat File Upload "Unsupported File Type" Fix**
* Fixed issue where uploading xlsx, png, jpg, csv, and other image/tabular files in the chat interface returned a 400 "Unsupported file type" error.
* **Root Cause**: `os.path.splitext()` returns extensions with a leading dot (e.g., `.png`), but the `IMAGE_EXTENSIONS` and `TABULAR_EXTENSIONS` sets in `config.py` store extensions without dots (e.g., `png`). The comparison `'.png' in {'png', ...}` was always `False`, causing all image and tabular uploads to fall through to the unsupported file type error.
* **Solution**: Added `file_ext_nodot = file_ext.lstrip('.')` and used the dot-stripped extension for set comparisons against `IMAGE_EXTENSIONS` and `TABULAR_EXTENSIONS`, matching the pattern already used in `functions_documents.py`.
* (Ref: `route_frontend_chats.py`, file extension comparison, `IMAGE_EXTENSIONS`, `TABULAR_EXTENSIONS`)

* **Manage Group Page Duplicate Code and Error Handling Fix**
* Fixed multiple code quality and user experience issues in the Manage Group page JavaScript.
* **Duplicate Event Handlers**: Removed duplicate event handler registrations (lines 96-127) for `.select-user-btn`, `.remove-member-btn`, `.change-role-btn`, `.approve-request-btn`, and `.reject-request-btn` that were causing multiple event firings.
