Phoronix: GIMP 2.4.0 Released
We've been covering the development of GIMP 2.4.0 for a number of months, and GIMP 2.4.0 is finally available! GIMP 2.4.0 is so new that their website hasn't been updated yet, but if you check out the GIMP FTP it is available for download as of October 23. We have some screenshots from an earlier GIMP 2.4 testing build.
