Sorry to jump in, and maybe I'll sound a bit disruptive but, I *think* 
that breaking backwards compatibility from time to time is a good thing 
(TM). For instance, the kernel devs do it for every version (yeah, there 
are reasons why they don't need to keep it, but also why it's better not 
to keep it). I wonder if it would be nice to plan for a release that 
breaks it, announcing it properly, planning it properly (what to break 
and what not, in a wiki, some months before the release, etc...). And 
it's not that I'm specially interested in this, but I've seen these 
problems in some cases, and this one seems the most important to me.
