**v2021.9.20 (202109200)**
- General enhancements - Manual capacitySync toggle (`[capacity_sync|cs] = [true|false]`) - it overrides the automatic. Both include the `freeze at 2%` feature. This is the actual `capacity_freeze2` replacement now. `capacity_mask` implies `capacity_sync`. - Unlike in previous versions, changes to `capacity_mask` and `capacity_sync` take effect (within a few seconds) without a daemon restart. - Updated documentation
