I was reading the Y! Mail updates blog today and it apears that a bunch of enhancements are out.  Too bad I don’t see them :-( .  I seem to be on web farm 503, based on the “f503″ in my URL and I have to just assume that the new enhancements (and the previously mentioned chat beta) just haven’t been deployed on my farm yet.

I would be best to not either not annunce updates until everyone can use them, or alert readers that a roll-out is in process.
