With Linux Mint's Cinnamon desktop environment they have been working to add Night Light mode support to the desktop. They are working on Cinnamon Night Light support both for Wayland and X.Org based sessions. Cinnamon is also seeing more work done around migrating dialogs to using Clutter.
The Linux Mint project has also begun collaborating with Framework Computer. As part of ensuring Framework modular/upgradeable laptops work great on Linux, they sent a Framework Laptop 13 over to Linux Mint to help ensure their Linux distribution and desktop are running well on their hardware. They are aiming to "achieve full compatibility with Linux Mint and the Cinnamon desktop" on Framework hardware.
