+## Current Issues (November 2025)
+
+### Issue: Settings Persistence and Autostart Creation
+**Status: RESOLVED - FIXED** ✅
+- **Fixed**: Settings now properly persist to config file when changed in UI
+- **Fixed**: Autostart desktop file is created when "Start on login" is enabled
+- **Root Causes Identified and Fixed**:
+  1. **Missing Signal Connection**: `start_minimized_switch` was created but never connected to `on_setting_changed`
+  2. **Logic Error**: `_previous_autostart_state` was set AFTER updating settings, making comparison always false
+  3. **File Write Buffering**: Added `flush()` and `fsync()` to ensure immediate disk writes
+- **Files Modified**: 
+  - `coremon/main.py` - Added signal connection and fixed state tracking logic
+  - `coremon/main.py` - Enhanced `save_settings()` with immediate disk sync
+- **Verified**: Settings persist across application restarts and autostart file is created/removed correctly
+
+### Recently Fixed: Autostart Cleanup During Uninstall
+**Status: WORKING** ✅
+- **Fixed**: prerm script now properly detects user and cleans up configuration files during uninstall
+- **Files Modified**: 
+  - `debian/coremon.prerm` - Added proper user detection logic
+  - `prerm` - Fixed file paths to use actual user directory instead of $HOME
+- **Verified**: Autostart desktop file and config directory are properly removed during package uninstall
+
+### Testing Status
+- Installation: ✅ Working
+- Application Launch: ✅ Working  
+- Default Config Creation: ✅ Working
+- Settings Persistence: ✅ WORKING
+- Autostart Creation: ✅ WORKING
+- Autostart Cleanup: ✅ Working
+
+## Versioning Process
+When making a new release:
+
+1. **Update version in setup.py**: Change the version string
+2. **Update application version**: 
+   - Update `__version__` variable in `coremon/main.py`
+   - Update About screen version display in `coremon/main.py` (search for "CoreMon vX.X.X")
+3. **Update Debian changelog**: Use `dch --distribution unstable --increment "Description"`
+4. **Build packages**: Run `./build-installer.sh` (creates universal installer in installer/ directory)
+5. **Test installation**: Verify universal installer works and version displays correctly in About screen
+
+**Important**: Always keep version numbers synchronized across:
+- `setup.py` (Python package version)
+- `coremon/main.py` `__version__` variable
+- `coremon/main.py` About screen display
+- `debian/changelog` (Debian package version)
