Release Notes

babel/babel

v7.2.3

Compare Source

v7.2.3 (2018-12-20)

This is a small release, mainily to test Lerna 3.
We force-published @babel/polyfill and @babel/preset-env, since they should have been released respectively in v7.1.0 and v7.2.2 but for different reasons they didn't get updated.

Half of the commits in this release are made by first time contributors! Thanks to @​cameron-martin, @​cphamlet, @​tanhauhau and @​jedwards1211. 🎉
