You can filter on more than one Date Range when creating a View, but you can now also select whether that Date range should use the operator of "AND" - ie all conditions should be met, or "OR" - where any condition needs to be met.

A great example of how this is useful is if you want to see a View of Activities from the past 14 days AND the next 14 days to give you a 28-day overview.
