Linux Mint 22 'Wilma' has a first Beta release available for testing, built on top of Ubuntu 24.04 it will be supported until 2029. With this being a Beta it's not recommended for everyone, only if you wish to test for issues and help get it primed for the full release that's likely due either late this month or early August.
A pretty big upgrade overall. Thanks to the jump in the Ubuntu package base it's using, with kernel version 6.8 along with Pipewire by default. With the newer kernel, you'll get support for newer hardware too.
