Foundation now require the `env` babel preset with a browserlist, but browserify config is oudated and still uses the `es2015` preset. Changes: * use the `env` babel prese for browserify transformation instead of `es2015`
Note: browserlist config is kept in ".babelrc" because browserlist external config is not supported by Babel < 7. See https://github.com/browserslist/browserslist
Update update and related packages to v7 beta. Changes: * Migrate to `@babel/*` packages * Use `@babel/preset-env` instead of `env` preset * Remove unecessary browserlist config in `.babelrc` config * Update Yarn lockfiles
