NON-ANNOUNCEMENT: The Glasgow Haskell Compiler, version 4.05?

[Alex Ferguson]

I've heard mutterings about the version count having gone up to 4.05,
but seen no announcement to this effect.  Is it still undergoing sea
trials, or something?

I ask as I'm pondering doing a source build or three, and I'm wondering
whether to do so from the released 4.04, or from the 4.05 CVS.

Cheers,
Alex.
