Any chance a new PyPI release will be out with this soon?

nbconvert 5 has started breaking my builds: https://stackoverflow.com/a/67061046/965332

I'm pretty sure that a new release is relatively imminent (we also need to bring in a new version of myst-parser)...not sure what's remaining to be done though
