Linux Mint 21.3 is due to release soon with a first Beta now available, coming with the Cinnamon 6.0 desktop with experimental Wayland support.
Don't expect Wayland with Cinnamon to work all that well right now though, as they said it still lacks various features and has a few limitations but they want to ready it up as soon as possible — although still likely not planned to be default even in Mint 22.x so it's a while away to replace Xorg.
Cinnamon 6.0 also has various other improvements including:
- 75% scaling is back.
- Window opacity keybinding is back.
- Stylus buttons can be disabled.
- The monitor used for notifications is now configurable.
- Menu apps can be edited with right click -> properties.
- Gestures: new desktop zoom action.
- Gestures: You can now specify when an action is triggered.
- Sound applet: new shift-middle click action.
- Grouped window list: new option to not show anything when hovering an app button.
- New "Spices" (addons) support for the right-click actions menu in the Nemo file manager.
The file-sharing application Warpinator also gained some new tricks like being able to manually connect to another device by its IP or by scanning a QR code. Their Hypnotix TV viewer application also gained new features like favourite channels, create custom channels and it can update its own version of yt-dlp for YouTube changes.
Linux Mint 21.3 will use the kernel 5.15 and Ubuntu 22.04 as a base and receive security updates until 2027.
