## INVENTORY

### <mark style="color:blue;">Bug fix</mark>

Some bugs, found in the previous version, have been fixed.

### <mark style="color:blue;">New toolbox function to check T candidate nodes with wrong topology</mark>

A new function has been added to **Giswater's toolbox** to check **T candidate nodes**. This mean nodes which appareantly have 3 arcs connected, but **topology is incorrect** and only one of this 3 really connects. Usually the problem is **one arc which is not broken** by the node.

This kind of problem is common when a new network is migrated from other sources and **could produce sever errors** while executing **hydraulic models** because of this lack of conexion.
