Building the 1.6 Release Notes as things are written.

[Scott Ritchie]

So, congrats everyone, 1.4 is out and I'm very happy about it :)

I wanted to thank Alexandre for his release announcement, it was very
through and informative.  It also looked like a lot of work.

This made me wonder if we could instead build up the announcement
gradually with some sort of process.  For instance, if every significant
feature added to a development release were put onto a wiki page, then
at any point in time we could point someone there to answer a general
"what does 1.5 have over 1.4?" question.

Come 1.6 release time, we could just copy and edit the page as the
official announcement.

Thoughts?
