CB-7774 capture updates from Hangout and mailing list

With the caveat, that we still semver CLI appropriately.  The "bar" here is: will this new CLI add features or break compatibility with existing plugins/platforms/projects.  If not, its just a point release.  However, updates to the pinned version may often correspond with new CLI features (new config settings or whatnot) and thus a MINOR bump may be common.
