+- Fix interval schedules by providing nowfun.
+- Removing code that forced last_run_at to be timezone naive for no reason, made timezone aware. Fixes crontab schedules after celery/celery#4173.
+- Entry.last_run_at is no-longer timezone naive.
+- Use a localized PyTZ timezone object for now() otherwise conversions fail scheduling breaks resulting in constant running of tasks or possibly not running ever.
+- Fix endless migrations creation for solar schedules events.
+- Prevent MySQL has gone away errors.
+- Added support for Django 2.0.
+- Adjust CrontabSchedule's minutes, hour & day_of_month fields max length
