  - `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`).  
  - A possible parser error that could result in a Trace Node ID in an input file not being recognized was fixed.
  - Additional API functions for enabling/disabling controls and rules were added (`EN_getcontrolenabled`, `EN_setcontrolenabled`, `EN_getruleenabled`, `EN_setruleenabled`).
- - Updated the internal function `getclosedlink` in report.c to use a loop instead of recursion to prevent a stack overflow during the analysis of very large disconnections.

+ - Updated the internal function `getclosedlink` in report.c to use a loop instead of recursion to prevent a stack overflow during the analysis of very large disconnections.
+- Setting the demand multiplier within the `[DEMANDS]` section of INP has been depreciated, please use `DEMAND MULTIPLIER` inside `[OPTIONS]` instead.
+- `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.
