I just wanted to add as another Git developer (with patches in this release and others) and with no affiliation with GitHub, that this skepticism of their motives that's taking up 1/2 the comments here is entirely unwarranted. I think it's also much better for a general audience like HN to link to these summary posts made by GitHub, Bitbucket and others than to the official release notes. The official release notes are quite terse, and much too long for someone who just wants a quick summary without getting into all the obscure details. They're also mostly ordered in whatever order Junio happened to integrate the patches, not by some order of importance or user-visibility. They also never show practical examples of how the feature can be used.
