Just stumbled across YSF plugin hours ago before you release the new version. I was really worried that the plugin is abandoned on RC stages. I will start using it again now. Is it more stable now?
Can't speak for others, but I run it on my server without any crashes. Not that it is properly tested on R2-1 only; R2-2 is supported since it is mostly the same as R2-1, but there could be some incompatibilities.
