Earlier quoted context omitted.
https://keybase.io/download just points back to github for source. You also haven't tagged anything more recent than that github release: https://github.com/keybase/client/tags If you're not tagging or doing github releases, is there a list of 'stable' versions that distros should consider packaging?
No, sorry. We're still making a new release almost every day, and we have no stable branches, only master. We'd prefer people to just install our own package.
I don't suppose you could tell us where the version number comes from then? I looked at opt/keybase/version of the 'now' package (20170214-1250 UTC) you host for Linux x64 and it says v1.4.12. What is the git commit reference for that version?
