- A new Flow Balance Report has been added to end of a simulation run's Status Report that lists the various components of the system's total inflow and outflow over the simulation period. It also displays the ratio of outflow to inflow as a check on flow continuity.

- A new type of valve, a Positional Control Valve (PCV), was added. It uses a valve characteristic curve to relate its loss coefficient to a percentage open setting (parameter - `EN_PCV`). - A new type of valve, a Positional Control Valve (PCV), was added.

- `EN_STATUS_REPORT` can now be used with `EN_getoption` and `EN_setoption` to get or set the type of status report that EPANET will generate (`EN_NO_REPORT`, `EN_NORMAL_REPORT` or `EN_FULL_REPORT`). - `EN_STATUS_REPORT` can now be used with `EN_getoption` and `EN_setoption` to get or set the type of status report that EPANET will generate (`EN_NO_REPORT`, `EN_NORMAL_REPORT` or `EN_FULL_REPORT`).
- `EN_PRESS_UNITS` can now be used with `EN_getoption` and `EN_setoption` to get or set the pressure unit used in EPANET. - `EN_PRESS_UNITS` can now be used with `EN_getoption` and `EN_setoption` to get or set a project's pressure units. The choices are EN_PSI, EN_KPA, EN_METERS, EN_BAR, or EN_FEET.
- Decoupled pressure units from the flow unit system, allowing them to be set independently to support mixed-unit conventions (e.g., using LPS for flow and PSI for pressure). - Pressure units have been decoupled from the flow unit system, allowing them to be set independently to support mixed-unit conventions (e.g., using LPS for flow and PSI for pressure).
