it hasn't been updated in ages, which is a shame really as last time I checked a lot of the super useful commands (like transforming an issue into a PR) were not working because of the v3 API
Would be nice to see someone take on maintaining hub, or at least fixing the broken stuff. Zach Holman spoke highly of it in "Git and Github Secrets" a few weeks ago.
I was under the impression mislav was maintaining it at the moment. At least I've seen some commits from him in the last 2 months, including some a few hours ago, although that might have been prompted by this thread.
