This is the "QuickSilver" release as it's main focus is speed, speed, speed. Previously diff-so-fancy did a lot of shelling out to read the git config (5+ per invocation). This slowed down start up and was a personal pet peeve of mine. After much tweaking we've decreased the startup time by more than 60%.
