In this minor release we reverted a recent change causing confusion with passed guest= flag (see #9687).
Note: BigBlueButton 2.2.15 contained the code change but due to a glitch the bbb-* packages reflect this change in 2.2.16 onward.
Several other improvements were included:
- Fix XML(Formula) Injection #9595
- Call onmount for custom arc-player #9732
- Add more blank slides to default presentation #9725
