Over at LWN.net, Nathan Willis has a nice summary of the Magit 2.1.0 features. Obviously he doesn’t cover all the features or even all the new features but it’s worth reading for getting an idea what’s in the latest release.
If you haven’t yet tried Magit, give Willis’ post a read and load Magit from Melpa. In the unlikely event that you don’t like it all you have to do is unload it. You won’t have to do any configuration to try it out so you can load it for a trial very easily and cheaply.
