 ### Breaking Changes
 
+-   Legacy support for `in` and `notIn` operators introduced in 0.8 .0 has been removed and they no longer work. Please, convert them to `is` and `isNot` respectively.
 -   Variables like `process.env.IS_GUTENBERG_PLUGIN` have been replaced by `globalThis.IS_GUTENBERG_PLUGIN`. Build systems using `process.env` should be updated ([#61486](https://github.com/WordPress/gutenberg/pull/61486)).
 -   Increase the minimum required Node.js version to v18.12.0 matching long-term support releases ([#31270](https://github.com/WordPress/gutenberg/pull/61930)). Learn more about [Node.js releases](https://nodejs.org/en/about/previous-releases).
