I've seen several times on this list people wondering what features
were in the works for 2.5 and what the status of the development was.
I did some grepping on the archive and put together a list of things
that have been discussed / worked on for 2.5 over the past year or so.

It's probably pretty incomplete and full of errors at this point but
I'll be happy to update it if you send me email.
