Pretty much stable. And a pretty interface and animations/effects.
Node previews now possible too! Default setup of content types are fully possible. Note that it has only been tested with Page and Story content types. CCK support not included. For current full support you might want to hack into live.node.inc and the companion JS file.
If you have any concerns about it, feel free to contact me!
Adds working template files for books, movies, software, and other media types, fixes a number of minor bugs, and generally moves us much closer to a final release candidate.
The essence of imagefield, condensed in less than 200 lines of code. Requires FileField 6.x-1.0-beta1 or later (or maybe not later but exactly, can't tell for sure yet).
Known issues:
- file preview doesn't work before saving the node when operating with private files
- thousands of nice imagefield features not implemented
Apart from that, I think this module rocks. You should definitely try it out on your development site (but yet keep it far away from anything involving production use).
