Breaking

This package now is using ESLint v10 and requires ESLint flat configurations.
Please refer to the README on how to adjust your configuration for flat config.

Potential pitfalls

Some of the used eslint plugins still keep a ESLint v8 compatibility,
this can cause some issues if not all packages are updated to the ESLint v10 compatible version.

If you see a linter error like the one below make sure to update all nested dependencies,
either using the sledge hammer method (remove the lock file and run npm i) or by running npm update.

TypeError: scopeManager.addGlobals is not a function
