In the latest Monthly News post, Linux Mint's Clement Lefebvre detailed some upcoming changes and improvements to the popular Linux distribution.
While news came recently that Canonical were getting their Ubuntu flavours to drop Flatpak by default, and Flatpak focusing on some big improvements, it seems Linux Mint continue to go with Flatpak too. In the post Lefebvre details they're creating XDG Desktop Portal implementations are being written for Cinnamon, MATE and Xfce. The point is to have better overall compatibility for the likes of Flatpak and libAdwaita apps.
Other changes planned include the Nemo file manager having multi-threaded thumbnails to make it faster, the Cinnamon desktop environment will have some back-end upgrades, and some important notes were included for Warpinator, their tool for sending files between systems.
Warpinator became quite popular when I first showcased it for transferring files to a Steam Deck (and then many other content creators followed along…), so it's nice to see some more focus on it. They had the SUSE security team go over it, and highlight some security concerns that needed sorting. They're now working on making it more secure, to isolate Warpinator from the rest of the system to ensure it can only write files where expected.
The most recent release Linux Mint 21.1 was back in December.
