I am using SourceTree (1.6.10.0), and I absolutely love it. The thing that puzzles me is the version of Git that is being used. The command prompt says
> Welcome to Git (version 1.8.4-preview20130916)
git-scm.com shows 1.9.4 as being the latest release for Windows.
My question is, why is a release that's over a year old being used? Was there a change in 1.9 that is incompatible? Performance reason?
