I released mrh v0.2.0, which takes into account that when latest upstream git reference does not match one that's checked out, it could be that upstream is ahead. The assumption previously was that local is ahead of upstream, implying that a push is needed. The API that helped with this change is Repository.graph_ahead_behind, a lovely and unexpected gift (commit).
I used cargo-outdated for the first time... I like.
I also released tag-helper, whose development was sponsored by Panoptix, the company I work for. The tool helps reduce the tedium of tagging git repos, of which we have a bunch.
