location of bzr.dev.weave?

[Jamie Wilkinson]

I'm trying to update a pre-knit working tree, but now the parent has changed
format, it can't update itself; I know the URL to the weave format branch
was posted about the same time as the 0.8 announcement, but I can't find it.

It's also not on the Key Branches wiki page, nor could I see it in the
Launchpad branches page for Bazaar-NG.

Can someone repost for me?  Thanks.
