ESLint v4.9.0 released

We just pushed ESLint v4.9.0, which is a minor release upgrade of ESLint. This release adds some new features and fixes several bugs found in the previous release.

Highlights

We’ve added 2 new rules with this release:

• multiline-comment-style
• lines-between-class-members

We also added new CLI option --fix-dry-run. This option will allow you to apply fixes without writing them to the disk.
