Unfortunately, 2.2 will not be coming in October as promised and is delayed to November. It just wouldn't feel right to release an update this big without stable servers and proper bugfixing. I tried my hardest to make it in time, but some work took longer than expected.
All I can do is apologize and do my best in these final weeks. I'm really looking forward to sharing all these new features with the community. /RubRub
