Changelog

  • Issue was not present in earlier versions, accidentally added a NULL check when struct wasn't initialized, forgot this isn't Go.
• Removed old source code.
• Refactored even more to remove unnecessary code.

v0.3.2 2024/07/22

• DO NOT USE: segmentation fault on real hardware.
• Fixed strange rendering bugs that would rarely occur (like phantom strokes that looked legitimate but were in the wrong place or color).

  • Add additional debug messages on boot.

v0.2.2 2024/07/08
