#### Breaking changes

This release drops official support for unmaintained long term support Node.js releases 14 and 16. It also drops support for non-long term support releases 19 and 21 and add support for Node.js 22. Only the `package.json`  `engines` field has been updated. The code should otherwise be identical to the previous 6.1.2 release.

Ensuring support for  older Node.js had become difficult as the GitHub actions runners are not available for the latest MacOS and recent pnpm also could not run on CI any more.
