The version 9.0.0 is not covered by your current version range.

If you don’t accept this pull request, your project will work just like it did before. However, you might be missing out on a bunch of new features, fixes and/or performance improvements from the dependency update.

It might be worth looking into these changes and trying to get this project onto the latest version of babel-eslint.

If you have a solid test suite and good coverage, a passing build is a strong indicator that you can take advantage of these changes directly by merging the proposed change into your project. If the build fails or you don’t have such unconditional trust in your tests, this branch is a great starting point for you to work on the update.

Release Notes

v9.0.0

v9.0.0

We've released v7: https://twitter.com/left_pad/status/1034204330352500736, so this just updates babel-eslint to use those versions internally. That in itself doesn't break anything but:

• Babel now supports the new decorators proposal by default, so we need to switch between the new and the old proposal. This is a breaking change.

To enable the legacy decorators proposal users should add a specific parser option:

{
  parserOptions: {
    ecmaFeatures: {
      legacyDecorators: true
    }
  }
}

• Babel removed the support for Node 4 , so I propagated that here.
