This is a summary of the major changes you need to know about for this version of ESLint.
Updating Rules for ECMAScript 6
We’re still getting a fair number of bug reports related to specific ECMAScript 6 features. The good news is that the bug report rate has slowed dramatically, so we’re getting to a much more stable place in terms of ES6 support. Keep those bug reports coming!
Scoped Plugin Support
This release adds support for scoped npm modules (beginning with
@eslint/, for example). This is a new feature that npm recently released, and we’re happy to follow up by allowing you to use scoped packages as ESLint plugins. See #2360 for more information.
With the ESTree changes in, we just have a few outstanding issues before releasing 1.0.0. Those issues are:
- #2302 - create a way to bootstrap
.eslintrcfiles for new users
- #2284 - should we switch to using 1-based column numbers instead of 0-based column numbers?
- #2226 - split space-in-brackets rule; implement array-literal-spacing and computed-property-spacing rules.
- #2225 - split space-in-brackets rule; implement curly-braces-spacing rule.
Reminder: we are preparing a list of breaking changes that will be coming in v1.0.0 and are tracking them on [[#1898](https://github.com/eslint/eslint/issues/1898)](https://github.com/eslint/eslint/issues/1898). Stay tuned to that issue so you know what to expect.
