As requested by many users, we have now limited the number of runs when the rules are run for a historical period. If you have the rule scheduled to run daily, then you can run it for the historical period of last 200 days. In the case of a weekly schedule, it will be for the last 200 weeks max.This basically helps prevent a huge number of rule runs being triggered by mistake, or when you don't realize how much time it is going to take for all the runs to complete. It puts all of the other rules in queue and delays other rule runs.
