- There is no longer a need for an explicit context argument to the tag. The code senses the right context using MovableType voodoo (looks at the stash).
- There is no longer a dependency on Digest::SHA1. Apparently MT 3.0 and above has SHA1 code built in (see MT::Util->perl_sha1_digest_hex();)
- Other things like a localized error message and making the tag work in a recent comments loop.
I've updated the documentation and you can download the new version there.
