The main new features of 2020.8 pro are:
- WordPress 5.5 changed the behavior of the parameter page in the url! You now get a 301 redirect on normal pages if you use ?page=XXX. Unfortunately this also kills url features of advanced iframe pro. You can now set “Fix WordPress 5.5 page parameter change” to true on the administration. Then you can again use ?page=abc for example again. Numeric values are still not allowed because removing this internally would kill the pagination where the page parameter is really used!

Have fun using advanced iframe pro,
