In previous versions, you could specify an update interval that affected all regions. If you've set the update interval to 2, ARM updated all your regions in the same tick every 2 seconds. That could cause some lags if you had many regions. With the new version, arm updates some regions with every tick so that it had updated all your regions after the given interval. That would also mean that you could reduce the amount of lags ARM causes if you have many regions by enlarging the update interval.
