# Updates # Updates
- Version 1.9
- Use logic LOW instead of HIGH as resting state. Fixes first LED was "laggy" issue.
- Version 1.8 - Version 1.8
- Renamed app to fit on Flipper Zero main menu screen - Renamed app to fit on Flipper Zero main menu screen
- Improved initialization to only happen when configuring the LEDs - Improved initialization to only happen when configuring the LEDs
