.env is not supported in a preset

Since i updated to latest beta,

 "babel-cli": "^7.0.0-beta.3",
 "babel-core": "^7.0.0-beta.3",
 "babel-node": "^7.0.0-beta.3",
 "babel-preset-env": "^7.0.0-beta.3",

i get this error

In my .babelrc I have "presets": ["env", "next/babel"]

I note in the current release v6 everything works fine but not in v7.
