6.3.16 Bug Fix babel-traverse: #3137 Set the correct parent and parentPath for new a NodePath (fixes an issue with export * from './a' and es2015-modules-commonjs). babel-generator: #3145 Always print "" in compact mode for consistency (gzip). Will be changed in a new mode (a supserset of compact) in a later patch. #3146 Don't print comments in compact mode. #3147 Don't print parentheses on throw statements with SequenceExpression. Internal babel-traverse: #3138 Support UnaryExpression in isPure check.
