I think we decided what we have today is fair enough to be released
and then built upon in subsequent releases.

AFAIK nothing has been done on that.

I am intending to continue working on performance, especially wrt
reducing the amount of sqlite queries we issue. This may still affect
APIs, so I don't think it's worth branching beforehand. Given my current
holiday and work schedule I cannot give an ETA though. I am making small
steps mostly.
As it stands, the libsvn_wc code is now using sqlite storage but is otherwise
still structured a lot like 1.6.x (we're doing per-node queries everywhere
and that is slow). There seems to be no big picture yet on how to
really get performance up. As I understand the situation, the original
designers of wc-ng expected that the current way of doing things would
perform well enough to be releasable. We now found that's not the case.
So we need to put more work into 1.7 to make it attractive for users
to upgrade to. Releasing in the current state would be a bad idea IMO.

At this point I'd be happy with that criteria.
A general note on branching: I think we have for a while now been
stabilising on trunk, and as far as I'm concerned we can continue
to do so until we consider trunk releasable. I don't think branching
will magically make the release appear any faster.
