Changes
- Fixes for various issues when two people edit a course at once
- Experimental support for subsections
Notes
- Since Multitopic format 4.2.0, it should be possible to remove any custom CSS previously added for the Multitopic format, as the built-in CSS should now be sufficient for a decent look. If you do have old custom CSS from a previous Multitopic version, it would probably be best to remove it, as it may cause a variety of issues.
