Hi,
Unfortunately, since everyone works, and has lives outside of Anope (except me), it leaves us with an informal idea of releases.
With that aside, I can try and touch base on a few things;
The 1.7.x releases are still classed as Development releases and NOT stable. The eventual goal with the 1.7 branch is to make it a 1.8 stable release thus in effect replacing 1.6.x as legacy. I use 1.7.14-svn on production networks with less problems than I experienced with 1.6!
MySQL Stage 3 is under development in SVN somewhere. It's a fairly big task but will yield benefits upon completion. Unfortunately, I have no time frame here as its less developed than bug fixing.
We are working on the site (particularly a modules repository replacement for the dirty list at the moment), and indeed going to plough resources into our Wiki and hopefully get some info going.
You are welcome to contact me if you do require any further information.
Hope this helps.
