I've just created a new page on meta. It is:

http://meta.wikipedia.org/wiki/Development_status

From the intro: "This page is intended as a place where developers can write their intentions for future development, and maybe even coordinate with each other (however unlikely that may be). Also, it should describe the current state of the two CVS branches and the live copy."

At the moment it's basically a personal to do list, but I'd be very happy if everyone else working on the PHP script also used it. It's similar to [[meta:Development tasks]] except it contains stuff that's actually going to happen in the forseeable future, and it says when it will happen.
