Hi Nathan,

Thanks for starting this discussion!

Wow, that *is* a lot.  One thing I am struggling with is that many of
these things aren't done -- but "done" is such a fickle concept that
maybe it's okay that we keep going.

Well, my preference is that 2.5 be the end of the line, but I think if
we release 2.5 now, we can probably also pull off a 2.6.

I'm working this morning on other projects, but this afternoon I'm
going to be posting documentation of where the 3.0 development is, and
what remains to be done before development can be moved over.  Last
week, Nathan, Stephen and I found a couple issues that required a bit
more thought, and I've been largely sidelined since then.  The big
things:

1) Ensuring that particle support is totally shored up
2) Covering grids, which need to be implemented (although I think I
now have an idea the best way to do so)

I'm going to write this afternoon with planning documents, following
on the discussion we had a few weeks ago.

This is a great idea.  I would really like to encourage people to
blog, by the way -- we get a surprising amount of traffic, and I think
it's a good way to get the word out about things like the plot window.
 And since you can use the notebook to do it, that just makes it
easier.

I think the release push for Enzo is taking a lot more energy than a
similarly timed release push for yt, but I understand where Cameron is
coming from in suggesting we hold off.  So maybe what we *could* do is
file tickets for the items (docs in particular) that need to be
changed and then once Enzo is out the door address the rest.
