ESLint 0.19.0 released

We just pushed ESLint 0.19.0, which is a minor release upgrade. This release includes new features and bug fixes.


This is a summary of the major changes you need to know about for this version of ESLint.

More ECMAScript 6 fixes

This release addresses the root cause of several issues related to ECMAScript 6 features. We previously were having a lot of trouble with scoping issues related to modules, destructuring, and destructured parameters. In this release, we fixed a whole host of such errors so our ES6 support should be really solid at this point.

ESTree Support for Default and Rest Parameters

The big parser upgrade to support the ESTree format for default and rest parameters is now complete. You can feel free to create custom rules using these features and feel confident knowing that the AST format will not be changing.

1.0.0 Update

With the ESTree changes in, we just have a few outstanding issues before releasing 1.0.0. Those issues are:

Reminder: we are preparing a list of breaking changes that will be coming in v1.0.0 and are tracking them on [#1898]( Stay tuned to that issue so you know what to expect.
