v0.5.3

• adds catch_up configuration setting for missed schedules
• updated to test with Django 1.7.10 and 1.8.4

If your cluster has not run for a while, the default behavior for the scheduler is to play catch up with the schedules and keep executing them until they are up to date.

With version 0.5.3 you can change this by setting the catch_up configuration to False.
The scheduler will then skip execution of scheduled events in the past. Instead those tasks will run only once and normal scheduling resumes.
