Subject Re: [DISCUSS] Geode dependency update process (review by 8/28/2019)
Date Tue, 13 Aug 2019 16:38:41 GMT
I like the idea of proactively updating dependencies after each release. For this to work we
would have to know whether the next release will be a major or minor release directly after
each GA release (so that we can bump either major or minor versions, as appropriate). How
and when do we currently determine our major release cycle? Would we know at the time of a
GA release whether the next release would be a major or minor release?
