Hi,
I use Source Tree from around 3,5 years. I always was really happy from it. I've installed few days ago latest version of source tree (2.1.2.5) and I suffer for a lot of issues. I didn't see any note that is beta version or anything like that. I really disappointed. One the end I even could open my source tree on my PC. It's just terible I had to install smart git and reisntall ST to version 1.
Regards,
Martin
