Many years ago, we forked django-wiki and departed the upstream repo. So the course wiki feature no longer benefits from security updates & new features from the upstream repo. This project looks at our options to improve the wiki situation, particularly the options of deprecation and getting back to using the upstream repo.
TL;DR
While not a critical feature of most courses, wikis are present in enough courses to make removing the feature problematic. There are about 10 material changes in our fork vs. upstream, several of which would likely be welcomed upstream if submitted as PRs. So while not trivial, a switch back to an upstream release seems feasible if some effort is dedicated to working with the upstream maintainer on it over a period of time.
Current Usage
The first questions to answer - how much is the course wiki feature used?
