i am using it. I started with windows and then switched to the mac version when it came out.
Getting the profile set up in Robohelp is tricky. I was able to get it to work but my co-worker is having issues (pending adobe support call) - it won't accept her ssh private key. My profile will initially show an error when selecting the ssh key but then clicking on the repo url field again seemed to correct it for me (and allow me to save) while it did not for her.
With update 2, you can select branches (update one only works with one branch - no switching). The push and pull works fine with bitbucket. NOTE: if you are working on a branch other than master, if you restart RH, it will automatically default to the master branch despite which branch you were previously working in.
