Beta releases

Beta releases are generated by the pkg.pr.new tool and are updated on every commit pushed to the main branch.

> [!Warning] > These beta releases get updated over time, so they are ill suited to be used as stable versions for a project (and the proper npm released should be used instead). These should be used only for quick testing of not yet released features/fixes.
