ESLint v3.12.0 released

Highlights

This is a summary of some of the notable changes in this version of ESLint.

Additional APIs

This version includes the addition of three new API methods:

• getRules to linter
• version to linter
• version to CLIEngine

Apologies for the lack of clear documentation on the above - our API documentation needs an overhaul, and we plan on updating this in the near future.

New option for eslint --init

This version adds the ability to pick the airbnb-base config without eslint-plugin-react, for those who want to follow the Airbnb styleguide but do not use React.

New Rules

One new rule was added:

• no-await-in-loop

Autofixing

Autofix support was added to the following rule:

• capitalized-comments
