2.0.0 (2018-01-18)

Features

Allow experimental syntax by default since most of babel users use experimental (not in ES-standard) syntax.

Breaking Changes

Changing embedAst option's default to true does not break builds but may slow your build time down. If you are aware that you are not using experimental (not in ES-standard) syntax, please use babel-preset-power-assert 1.x for the former behavior.
