There are no changes to the parser or rules required, which means that we just need to:

1. regenerated libs
2. bump dep ranges.

Considering that there are no new changes to the parser or rules, when should we see an update? That runtime warning is very annoying and in some particular cases it gets printed multiple times (when used as pre-commit hook, due to multi-process use).

#4615 merged a few hours before your comment. I would imagine we could see a release today, if not likely early next week. It seems like this package releases versions fairly regularly, so we probably won't be waiting long.

We release automatically every Monday morning!
