Aseprite and its LUA API changed significantly since the last release, a lot more is possible now than was in October of 2020.

This update is a long-overdue rewrite that introduces improvements to the overall user experience, not a lot of changes in terms of functionality. However, some features that did not add much value or proved to cause issues were cut for the sake of a better, more stable experience.

Changelog:

• Advanced Scaling
  • [Change] Removed Hawk algorithms
  • [Improvement] Reworked dialog for better user experience

• Add Inbetween Frames
  • [Improvement] Reworked dialog for better user experience
  • [Improvement] Frames selected for tweening are now highlighted on the timeline
