Brodie Rao <brodie@sf.io> [Mon, 16 Sep 2013 01:08:29 -0700] rev 20185
branchmap: cache open/closed branch head information This lets us determine the open/closed state of a branch without reading from the changelog (which can be costly over NFS and/or with many branches).
Mon, 11 Nov 2013 21:16:54 +1100 bookmarks: allow push -B to create a new remote head (issue2372)
Stephen Lee <sphen.lee@gmail.com> [Mon, 11 Nov 2013 21:16:54 +1100] rev 20184
bookmarks: allow push -B to create a new remote head (issue2372) Push is currently allowed to create a new head if there is a remote bookmark that will be updated to point to the new head. If the bookmark is not known remotely then push aborts, even if a -B argument is about to push the bookmark. This change allows push to continue in this case. This does not require a wireproto force.

Matthew Turk <matthewturk@gmail.com> [Thu, 21 Nov 2013 15:46:49 -0500] rev 20183
template: modify showextras to return a hybrid This modifies slightly the behavior introduced in 519120a96c63 to allow showextras to return a hybrid, rather than showlist. The example in the template help file now executes and returns meaningful results.
Fri, 15 Nov 2013 23:18:08 -0500 branches: avoid unnecessary changectx.branch() calls
Brodie Rao <brodie@sf.io> [Fri, 15 Nov 2013 23:18:08 -0500] rev 20182
branches: avoid unnecessary changectx.branch() calls This requires reading from the changelog, which can be costly over NFS. Note that this does not totally remove reading from the changelog; we still do that when calling changectx.closesbranch(). That call will be removed in a later patch.
