It's been a while since I wrote anything here.
Over the last few weeks I rewrote the GIF writer to avoid the GIF specific options handling, and to use tags instead. I also added some compatibility code to convert the older parameters (warning by default.)
Beyond this Imager has had a lot of work done on it since October, including a bunch of bug fixes, a reorganization of the documentation, which will hopefully make it less unwieldly, and support for Mac OSX.
Addi's considering releasing 0.40 soon, so if you're reading this please pull down Imager CVS and give it a go
