Webapp2 is now an Open Source project maintained on
Github. The community has already added support for Python 3 as per the
git report here. The Google Cloud App Engine Standard team is also working hard on supporting new runtime versions, and Python 3 is definitely on the list (currently there is no ETA). Note that you can already use
Python 3 on App Engine Flexible.
- For any further Webapp2 specific issues and requests it is recommended to use their
Github tracker.
