In testing the latest version 2019011700 release 3.6.1 from Moodle.org on Moodle 3.7 (Build: 20190520) I'm seeing the following notices with debug enabled, although the plugin does still appear to function - just seeing if it's acceptable to run this version on M37 and if this would cause any problems when running the plugin on that version once it's available to clients:
Please do not call get_users_roles() with $checkparentcontexts = true and $userids array not set. This combination causes large Moodle sites with lots of site-wide role assignments to run out of memory.
