Release Notes for EPANET 2.3

This document describes the changes and updates that have been made in version 2.3 of EPANET.

• The check for at least two nodes, one tank/reservoir and no unconnected junction nodes was moved from EN_open to EN_openH and EN_openQ so that partial network data files could be opened by the toolkit.
• A EN_setcurvetype function was added to allow API clients to set a curve's type (e.g., EN_PUMP_CURVE, EN_VOLUME_CURVE, etc.).
• A EN_setvertex function was added to allow API clients to change the coordinates of a single link vertex.
• The index of a General Purpose Valve's (GPV's) head loss curve was added to the list of editable Link Properties using the symbolic constant name EN_GPV_CURVE.
• The EN_getlinkvalue and EN_setlinkvalue functions were updated to get and set the value of EN_GPV_CURVE.
• Negative pressure values for EN_SETTING are now permitted in the EN_setlinkvalue function.
• The EN_STARTTIME parameter was added into the EN_settimeparam function.
• The calculation of head loss gradient for low flow conditions was corrected.
• Improved updating and convergence tests were added to pressure dependent demand analysis.
