The postmarketOS team has started a community testing team and asked
users of Sxmo to join. Joining the testing team will prevent regressions
from appearing in stable releases and improve the quality of
postmarketOS+Sxmo for your device. Moreover, you will get to test new
changes before anyone else!
Please take a look at the blog post by postmarketOS:
Thank you for using postmarketOS+Sxmo and happy hacking!
