Subject Re: Apache MADlib next release discussion
Date Fri, 29 Sep 2017 00:22:49 GMT
+1 on the 1.13 release. We can add our new features that don't require
interface change to 1.13, and take more time for 2.0 features/interface
change. Looking forward to new features and feature improvement in 1.13!
