Re: What stands between us and branching 1.7?

It looks like Philip's list was added to the issue tracker with the
1.7.0 milestone. Nice.

I know CMike has been going through that list and fixing, closing,
moving items. Are all of the items left in the list things that we
definitely want/need for the release? For example, I see a couple of
tree conflict items that I assume no one plans to work on.

Since this list seems to be a good one for knowing what is left to do
before we can branch it would be worth it to remove anything in the
list that we can.

For reference, here is the list:
