Subject [CANCELLED][VOTE] Release Apache MXNet (incubating) version 1.4.0.rc1
Date Fri, 25 Jan 2019 02:34:23 GMT
Dear MXNet community - cancelling the vote to address the performance
degradation. Please do not merge any other changes into 1.4.x branch to
keep the branch stable to get the 1.4.0 release shipped eventually.

Regards,
Steffen
