@babel/traverse 7.0.0-beta.52 on Node.js Yarn

v7.0.0-beta.52 (2018-07-06)

Deprecating the yearly/stage presets in v7 (will remove next beta). Ran npm deprecate on @babel/preset-es2015, @babel/preset-es2016, @babel/preset-es2017, @babel/preset-stage-0, @babel/preset-stage-1, @babel/preset-stage-2, @babel/preset-stage-3 only for versions >v7.0.0-beta.52. This means this will only break your build if you are using ^ in Babel v7 beta (which we have recommended against each release). (It is unfortunate that the default behavior of npm is to use ^ when using npm install though; haven't made an RFC for it yet).
The pipeline plugin must be configured with the minimal option. This is so people explicitly know the implementation that is being used, and someone will be able to implement and test out the other proposal options. After all, this proposal is in Stage 1 still and the semantics are being figured out: this is a great opportunity to specify via the config what people are using.
