So far UploadColumn has been a real success, it works pretty much exactly like I want it to. This means that to me it feels like there shouldn’t really be any changes to the API, however there should be some improvements to internal structuring as well as a few new features.
* tmp_dir defaults to public/tmp
* abstract tmpfile/stringio into a SanitizedFile class.
* Add support for generic manipulation engines/processors.
* Add engines for ImageScience and possibly minimagick.
* Built in support for GIF animations
Competition has gotten stiffer now with Rick’s excellent attachment_fu, imho a mighty improvement over acts_as_attachment. I hope I have time to implement those features for 0.3 and to me it looks like UploadColumn will be mostly feature-complete at that point. From then on it’s only stability and compatibility fixes revving up to ver 1.0.
