Dear Scheduler users
I have now marked the latest release of Scheduler (3.7.0) as compatible with Moodle 3.9 in the Plugins directory.
This is not a new release - it's just to confirm that, according to my tests so far, Scheduler works on Moodle 3.9 just as well as on 3.7 and 3.8. If you saw any imcompatibilities, please report them here or on the Moodle Tracker.
I'm still hoping to release a new version with bug fixes and (hopefully) added features later this year, but it will probably be more towards the end of the summer.
