Hi extension authors,
The last release consists of a refactoring of significant pieces of the source code of DokuWiki. Most pieces had some fallback. But still there were challenges. Also it is important to update code that still has a fallback in place.
To help you out, you could find here some guidance: https://www.dokuwiki.org/devel:releases:refactor2020
If you have suggestions, missing parts, errors or other points of attention, please respond!
Note: Please try to focus this thread on the guidance page itself. (For debugging your specific plugin it is better to launch a separate forum topic. Thanks!)
