Just a heads up that we're going to push out a yt-1.6 point release just around the New Years. It'll be taken from the trunk+a bit of hg, which means basically:
(Have I missed anything else that's in trunk / hg but not 1.5?)
As you can see, most of the major, user-visible features for this release are Stephen's. He's already documented most, as well. Congratulations and thanks, Stephen! I'll work to document the updates I'm responsible for, as well.
