As reported on gimpusers.com, a new version of the GIMP Animation Package GAP has been released. It’s optimised for interacting with GIMP 2.6.x and has a set of cool new features. A build for Windows is also available.
GAP was featured in Episode 21 of Meet the GIMP – perhaps it is time for a new look into this corner.

A little late, but I for one would be quite interested to see a new show about this. Most of what I find about it is just links to the news that it has been released, essentially what this post was. Thanks.
I think Philippe is the right guy for this, I haven’t looked so deep into GAP, but Philippe did parts of the intro with GAP.
