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.
