## Source excerpt

It's the end of another year, and we're happy to announce the v21.12 release of postmarketOS, based on Alpine Linux 3.15! Thanks to our amazing contributors, the amount of supported devices has been increased to 23 (from 15 in v21.06). As in previous releases, we ship pre-built images for phones and tablets with the mobile-optimized Phosh, Plasma Mobile and Sxmo interfaces. Other form factors, such as the PineBook Pro get images with different interfaces as it makes sense. In the picture above it runs Plasma Desktop, and besides that we have Gnome, Sway, Phosh and Console. Find all images at the download page. v21.12, like previous releases, is geared mainly towards Linux enthusiasts; it may be a bit rough around the edges so expect some bugs. Help identifying and resolving issues is always greatly appreciated.
