--- upgrade: - | Since we now use Placement to verify basic CPU/RAM/disk resources when using the FilterScheduler, the ``RamFilter`` and ``DiskFilter`` entries are being removed from the default value for the ``enabled_filters`` config option in the ``[filter_scheduler]`` group. If you are overriding this option, you probably should remove them from your version. If you are using CachingScheduler you may wish to enable these filters as we will not use Placement in that case.
