 - `EN_PRESS_UNITS` can now be used with `EN_getoption` and `EN_setoption` to get or set the pressure unit used in EPANET.
 - Continuous barrier functions were added to constrain emitter flows to allowable values.
 - The `EN_openx` function has been added to enable the opening of input files with formatting errors through the API. This allows users to continue using toolkit functions even when such errors are present.
+- Fixed a bug in EN_setnodevalue with EN_EMITTER option that could cause NaN results.
