I will stop building 10.1. CM has frozen the code of 10.1 so every bug that is related to upstream code will not get accepted.
If there are any major device-specific fixes in the future, I might release a final build.
I am also planning to stop cm10.2 support when CM releases their final build in a few days/weeks, so I can fully focus on cm11. All devs have left the 2011 scene, I'm only one person and I can't maintain everything. Let's hope I will manage to get the new kernel that I'm working on running soon. That might attract some devs back to 2011 line.
