Changelog v.0.2.5

Breaking Changes

Native ESP-IDF Migration

  • Replace Arduino/Adafruit libraries with native ESP-IDF drivers (BME280, MPU6050, MPU9250, QMC5883, PSRAM, WebServer, Battery)

Performance Improvements

  • Render map optimization (polygon fill, border caching)
  • Scroll map optimization (multi-core prefetch, physics improvements)
  • SD file access optimization (fstat, single-read palette)

Code Cleanup

  • Remove unused draw commands and rendering code
  • Code refactor (PROGMEM, delay, millis, digitalRead)
