I take that back, I can test, sort of. Thanks, Travis: https://travis-ci.org/tkelman/homebrew/builds/70413319

libgit2-glib failed on testing. Probably needs a revision if there isn't a version bump available.

Thanks, I don't see a newer tag than 0.22.8 yet at https://github.com/GNOME/libgit2-glib/releases. It looks like adding revision 1 to libgit2-glib would cause a build failure against latest libgit2 (https://travis-ci.org/tkelman/homebrew/builds/70429110), so will this have to wait until libgit2-glib puts out a new release?

[DomT4]

Yup, looks like it. They're usually fairly in-sync.
