What’s New

Version 8.7

I apologize for the inconvenience caused by my careless mistake.
This time, I checked the performance properly, so I think it's probably OK!

- Fixed a bug that RunCat crashed and never started when a user sets to show the CPU usage in the menu bar.
- Fixed a problem that the animation disorders when updating the speed of the runner on macOS Big Sur.
- Switching between light mode and dark mode has become lighter.
- The progress circle is displayed when loading the runner store.
- For compensation, added free runners "Party Cat" and "Party Parrot".
