Subject Re: [VOTE] Release Apache MXNet(incubating) version 1.2.0.RC2
Date Fri, 04 May 2018 18:32:42 GMT
I agree with Anirudh that the focus of the discussion should be limited to
the release branch, not the master branch. Anything that breaks on master
but works on release branch should not block the release itself.


Best,

Haibin
