ESLint v9.10.0 released

We just pushed ESLint v9.10.0, which is a minor release upgrade of ESLint. This release adds some new features and fixes several bugs found in the previous release.

Highlights

Types now included

We’ve been receiving complaints about the @types/eslint package not being updated after the v9 release. While we did do an initial update to the package for v9, it quickly became apparent that regular updates to that package could not be accomplished in a timely manner. Ultimately, we decided that the only way for us to provide the type of experience we want for ESLint is to take complete ownership of the type definitions.

As a result, beginning with this release, the eslint package now publishes its own types. To start, we’ve copied the type definitions from @types/eslint in order to provide a smooth transition. (There was one bug in the types that we fixed, but otherwise it’s the same type definitions.) Going forward, we’ll continue to iterate and improve the type definitions as part of our regular release cycle.

We’re grateful to everyone who contributed types to the @types/eslint package at a time when we weren’t ready to take that work on.
