Adds layers, additional Game of Life rules and boundary modes, RLE import, auto-reseeding, full-screen previews, calendar overlays, translations, and improved BOOX settings. Includes UI, performance, and reliability fixes.

Usage:
- Install the app on using F-Droid or building from source.
- Disable freezing in order to for the game to self-update

- (Optional) Enable the calendar overlay and choose which synced calendars may appear on the screensaver

Calendar privacy and refresh:
- Calendar permission is optional and read-only

- Event details are not cached, and calendar settings do not transfer to another device
- Calendar content refreshes with the regular wallpaper job or while the app is open

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
