+- **NVM Dump Window**: Moved NVM dump functionality from Firmware Manager to Devices menu for better organization
+  - Standalone window with tabbed interface
+  - "Dump NVM", "Clear View", and "Clear Firmware (Reset NVM)" buttons
+  - Dedicated output area for NVM data
+- **Firmware Manager Auto-Sizing**: Window now automatically scales to fit all device content based on screen size
+  - Dynamic height calculation (480px per device)
+  - Minimum size of 1000x700 with fallback to 1200x900
+  - No more need to manually resize window
+
+### Changed
+- **Serial Number Panel**: Now visible by default on first launch (was hidden)
+- **Serial Number Input**: Redesigned layout and improved usability

+  - Moved input bar next to "Serial Number" label
+  - Removed redundant "Current:" text
+  - Improved auto-increment checkbox sizing
+  - Info text updated to reflect auto-save behavior
+- **Device Manager Width Calculation**: Changed to pure percentage-based limits (45% max) to handle UI scaling better

+
+### Fixed
+- **Conditional Statement Warnings**: Fixed bug where `if` conditions triggering warnings would show "Step complete" instead of the warning message
+  - Status now correctly preserved when script is in error hold state
+- **Scanner Input Injection**: Fixed scanner input being typed into script editor when cursor was focused there
+  - Implemented "scanner mode" that blocks character propagation during rapid input
+  - Scanner handler now runs first via `bind_all` with `add=True`
+- **File Wipe Bug**: Fixed critical bug where autosave could wipe file contents during loading
+  - Added `loading_file` flag to prevent autosave during programmatic edits
+  - Files are now safe during all load/recovery operations
+- **Device Manager Width Persistence**: Fixed issues with saving/restoring panel width
+  - Added stricter validation for saved widths
+  - Improved retry mechanism for widget sizing
+  - Better debug logging for troubleshooting

+  - Serial number settings dialog accessible via Settings menu
+  - Toggle panel visibility via Settings → "Show Serial Number Panel" (off by default)
+  - Real-time feedback on scanner activity (no misleading "ready" status)
+  - Comprehensive documentation (SERIAL_NUMBER_SYSTEM.md, SERIAL_NUMBER_QUICKSTART.md)
+  - Example scripts demonstrating serial number usage
+  - Test suite for serial number functionality (test_serial_system.py)
+
+### Fixed
+- **Firmware Manager mousewheel crash**: Fixed `TclError: invalid command name` exception that occurred when scrolling mouse wheel after closing the Firmware Manager window. Added proper event binding cleanup in window close handler.
