So I pushed versions 4.4.2.3 (buster) and 11.0.9.2 (bullseye) which include the following fixes in an attempt to address major issues discussed since the stable release. However these are untested because I have no proper real-life server on which to test those. We are looking for tech-savvy users running a Raspberry Pi willing to test the Buster->Bullseye and make sure that those patch don’t make the server explode
