Releases and what is the workflow

[Aekold Helbrass]

Hi All!

Dev Guide page about releases is almost empty:
http://openjdk.java.net/guide/releases.html
Are there some drafts explaining currently existing releases and their
workflow? If yes - please give some links.
If no - please explain in few words, are changes from jdk7u2
backported to jdk7u, are changes from jdk7u backported to jdk7, what
means gate and what means development in repositories list, and if I
want to create a fork and keep it up to date through u2-u3-u4 and so
on - what release is the best for me?

Thanx!
