Seems reasonable to also publish this (i.e., go straight to 0.20.1).

Had an issue with the ^0.5.0 package:web constraint yesterday and came here to see if it was reported/worked on. This constraint is very problematic for many packages as they cannot update to needed newer package:web versions with it in effect, as it limits intl to package:web versions below 1.0.0, which are too old. Happy to see it addressed, we need a new package release with the fix too.

Dependency override seems to work OK though.
