Dear Scheduler users
I have just made a maintenance release (v3.1.1) for Scheduler available on the plugins DB. This resolves a compatibility issue with the upcoming Moodle 3.2.
Note that previous versions (in particular 3.1.0) will not work on Moodle 3.2 due to a change in the core code for action menus - the "Add slots" and "Delete slots" menus in the teacher view may fail to open.
