 - The deprecated <code>RunSnowModule</code> argument has been removed from the <code>CreateRunOptions()</code> function. ([#23](https://gitlab.irstea.fr/HYCAR-Hydro/airgr/-/issues/23))
 
 
+#### Bug fixes
+
+- Fixed bug in <code>RunModel_GR1A()</code>. Reversed PotEvap and Precip outputs are now reordered (in the previous versions PotEvap contained the precipitation values and Precip contained the evapotranspiration values, the Qsim values were already correct).
