Hi,
I've released the current darcs version of CFFI as 0.9.0. The darcs tree has been tagged and checkpointed, and I've uploaded a signed tarball to public_html/releases and updated the package link on CLiki.
I consider this the "beta" release leading up to a real 1.0 version. I think the next step is to look at the TODO list and determine which things need to be done before 1.0, and which should wait until after. Primarily I'm concerned with bugfixes, finishing the incomplete sections of the manual, and adding tests to cover all CFFI functions.
