The big news with this release is that it's the first to support Windows. I've been using this on linux for a year as a hobbyist Photographer and it's exceedingly glorious. Have not tried out the Windows build but apparently you can do that now [1].
Also if you want to learn a lot about "developing" digital photographs (it really is a digital darkroom), I learned a lot from this youtube list of 42 Darktable tutorial edit sessions [2]. Very powerful and fun stuff.
