The typing improvements focus on making the WSGI and ASGI App types generic (parametrized by the request and response types). This should make it significantly easier to properly annotate applications that leverage custom request and/or response types.
Additionally, we have fixed a reproducibility issue (thanks to @bmwiedemann from openSUSE for reporting!) in our documentation build process. Regarding packaging Falcon for distributions in general, we would like to remind you of the Packaging Guide that was published with the previous Falcon release (4.1.0). We hope this guide proves useful.
This release also incorporates a number of pull requests submitted by our community. Sincere thanks to all 8 contributors who made this release possible!
