Subject Re: [DISCUSS] Thinking about branch names
Date Tue, 23 Sep 2014 15:45:46 GMT
Personally, I like the succinctness of "1.5" over the ones you
presented. I don't feel like "1.5.x" or "1.5-dev" tell me anything
more than "1.5" already did so they just turn into more typing. I
don't really think there's a high chance that we ever abandon x.y.z
version strings, so there isn't a big chance for it to look like a

For context, Hadoop (and other related projects) tend to do a
"branch-X" and "branch-X.Y". For the same reasons as above, I feel
like the "branch-" is unnecessary.

Is anyone else concerned about potential confusion having "x.y" branch names?
