After months of hard work from our amazing community, we are proud to announce the second beta release of postmarketOS, based on Alpine Linux 3.13. The amount of supported devices has been increased from one (just the PinePhone in v20.05) to no less than eleven - and all of them run a (close to) mainline kernel!
Each device is able to run modern phone shells Phosh, Plasma Mobile and Sxmo. The Nokia N900 is an exception of course, for that one we recommend running i3.
As mentioned in the header of the blog post, in its current state, postmarketOS is for Linux enthusiasts. Expect bugs and help out with fixing them. It's a long hard road to an alternative smartphone OS that doesn't track its users, gives back control and makes a long lifetime feasible. But we are making steady progress, and when compared to when we started out, a huge community has been established - not only within postmarketOS, but also a whole ecosystem of other projects that share the same goal and work together.
