AttributeError: module 'collections' has no attribute 'MutableMapping'

This was fixed in https://github.com/nengo/nengo/commit/e9a62698904915f0071deea8cf392903439a57c5 by changing collections.MutableMapping to collections.abc.MutableMapping, but nengolib is pinned to nengo<3.0. Manually upgrading nengo:

$ python3 -m pip install --upgrade nengo

yields another error:

It looks like these were last edited in December 2019. Will there be any fix in the foreseeable future?
