OSMC's September update is here with Debian 11 (Bullseye)
In May, we released test builds of Debian Bullseye for all supported OSMC devices. For the next four months, we've been working hard on a number of improvements and fixes to ensure that OSMC is released on the latest version of Debian with the best experience possible.
We are still shipping Kodi v19.4, as a 19.5 point release has not yet been finalised. However we have updated the version we ship to the latest commit on the Kodi Matrix branch.
