There was some debate whether or not to remove the rule requiring a 60% vote to end filibusters in the Senate. Because this rule still stands, most laws cannot pass without 60 Senators' votes. Budget reconciliation bills, however, can be advanced with only a simple majority of the Senate. Though this is not a recent rules change, much recent legislation has gone through the reconciliation process to avoid the supermajority requirement.

Thanks! That must be the debate I remember happening and thought they actually made the change.
