- Bump version for next release - Fix default gamma for CYD 2432S032C - Remember gamma curve setting from Display settings app - Add UART to Core2 (still has no voltage on Grove port, though) - LVGL performance improvements: pin to second core and set task priority to "critical" - Fix build warnings, including deprecations - Removed deprecated `Thread` constructor - Fix WaveShare S3 display: Some displays would show a white screen at 12MHz, so I'm putting it back to the official config values.
