Color management is now a core feature of GIMP rather than a plug-in. This made it possible, in particular, to introduce color management to all custom widgets we could think of: image previews, color and pattern previews etc.

GIMP now uses LittleCMS v2, which allows it to use ICC v4 color profiles. It also partially relies on the babl library for handling color transforms, since babl is simply up to 10 times faster than LCMS2 for the cases we tested both of them on. Eventually babl could replace LittleCMS in GIMP.
