ESLint v10.0.0-rc.1 is now available for testing. Key changes include built-in TypeScript type definitions for Espree and ESLint Scope packages (replacing Definitely Typed versions), fixes to the no-shadow rule for function and class expression names, and improvements to RuleTester. A migration guide is available to help users upgrade, though most should be able to update without build changes. Install using npm with the 'next' tag or by specifying the version directly.
