Oooops! I'm on Ubuntu 14.04.3 LTS (just done apt-get update/upgrade) and my git version is 1.9.1 ...
On Ubuntu, you can get the latest version via:
sudo add-apt-repository ppa:git-core/ppa
sudo apt-get update
sudo apt-get install git
git --version
Note that this is at "git version 2.5.0"This updated Git for Windows project brings that same version to Windows.
Git on Windows has been stuck at 1.9.* for awhile and always in "preview" because it was never really meant for production usage since the main contributor wasn't able to spend much time on it (and even then, he didn't primarily use Windows): http://episodes.gitminutes.com/2014/04/gitminutes-28-johanne...
I applaud the work that Johannes Schindelin (and others) did to get Git on Windows for these past years of increasing usage and look forward to this project taking it to the next level.
