v0.120.0

Compare Source

There are no major nor breaking changes in this release. ☕️

The internal reference documentation now uses annotated_doc.Doc instead of typing_extensions.Doc, this adds a new (very small) dependency on annotated-doc, a package made just to provide that Doc documentation utility class.

I would expect typing_extensions.Doc to be deprecated and then removed at some point from typing_extensions, for that reason there's the new annotated-doc micro-package. If you are curious about this, you can read more in the repo for annotated-doc.

This new version 0.120.0 only contains that transition to the new home package for that utility class Doc.
