Last Thursday I made a prerelease of gimp-perl (aka the Gimp module for perl), using the Gtk2 perl module. Still lots of stuff wrong, needing attention, but it either runs most of the scripts that come with it now or documents which ones are still broken. This type of QA is long long overdue. Am pretifying the interface, updating things to Gimp2 equivalents, etc while I'm at it.
Wasn't overly involved in the Gimp release proper; mostly just submitted bug reports that are clear enough to follow and I'm pretty sure were bugs. The mitch/sven combo dealt with most of them in sub-24hr timeframes - very impressive.
Have grown annoyed enough with one personality on #gimp that I've invoked /ignore. To that person if you're listening - if you don't know what you're talking about, please learn to listen rather than just spew garbage to my screen. Or at least learn to ask more sensible questions.
