For people wanting to install Linux Mint on newer devices, the Linux Mint team have announced a plan to update their EDGE ISOs with a later Linux kernel in the latest blog post.
The blog post goes over recent funding, of which December 2023 was a high-point and the most they've seen donated to the project all year at $24,146 USD but still just below last year's level.
Giving an update on the status of the upcoming Linux Mint 21.3 release, the Beta phase sounds like it's going well with 50 bug reports being sent in and 35 of them already closed. Linux Mint Debian Edition 6 will also be getting all the improvements from the main Linux Mint 21.3 release.
For the 21.3 EDGE ISO, which they provide for people who have issues booting systems with their main downloads, they will be releasing a 21.3 EDGE ISO with Linux kernel 6.5 as they said "During BETA testing we identified compatibility issues between Linux Mint and new hardware devices (recent AMD graphics but also wireless chipsets and SSD controllers used in Acer laptops). These are solved by upgrading the kernel series from 5.15 to 6.5.".
Since they go by what kernels Ubuntu officially provide, since Mint is based on Ubuntu, they're stuck with whatever the latest Ubuntu provides since Mint don't package up their own kernels.
