+RELEASE HISTORY OF THE airGR PACKAGE
+
+
+#### 1.0.5.6 RELEASE NOTES ###########################
+
+- Bug fixed in DataAltiExtrapolation_Valery(). The elevation gradients for air temperature returned by CreateInputsModel() are improved.
+
+- DataAltiExtrapolation_Valery() and CreateInputsModel() now present a PrecipScale argument which allows rescaling precipitation when it is interpolated on the elevation layers when CemaNeige is used.
+
+- DataAltiExtrapolation_Valery() has been improved. DataAltiExtrapolation_Valery() now runs faster (and by consequence CreateInputsModel() too when CemaNeige is used).
+
+
+#### 1.0.4 RELEASE NOTES ###########################
+
+- RunModel_CemaNeigeGR4J, RunModel_CemaNeigeGR5J() and RunModel_CemaNeigeGR6J() now return air temperature for each elevation layer. 
+
+- S3 plot method defined for OutputsModel objects. It means that the plot_OutputsModel() function is deprecated and his use has been replaced by the use of plot.OutputsModel() or plot().
+
+- In plot.OutputsModel() the PlotChoice argument is deprecated and has been renamed "which".
+
+- plot.OutputsModel() displays air temperature time series for each layer when CemaNeige is used (argument which = "Temp" or "all").
+
+
 #### 1.0.3 RELEASE NOTES ###########################
 
 - Bug fixed when StartParamList or StartParamDistrib arguments are used in the CreateCalibOptions() function.
@@ -8,6 +32,7 @@
 
 - ErrorCrit*() functions gain a warnings argument to replace the verbose action and the verbose argument now prints the criterion value(s).
 
+
 #### 1.0.2 RELEASE NOTES ###########################
 
 - The RunModel_GR6J() and RunModel_CemaNeigeGR6J() models were modified back to versions previous to 1.0.1 to prevent from unwanted efficiency criteria deterioration related to the calibration with Calibration_Michel().
