 Description: Hydrological modelling tools developed at INRAE-Antony (HYCAR Research Unit, France). The package includes several conceptual rainfall-runoff models (GR4H, GR5H, GR4J, GR5J, GR6J, GR2M, GR1A), a snow accumulation and melt model (CemaNeige) and the associated functions for their calibration and evaluation. Use help(airGR) for package description and references.

+#### CRAN-compatibility updates
+
+- The run period is reduced in the example of the <code>Imax()<code> function in order to run faster.
+
+- The 'hydroPSO' package is no longer suggested (but the code linked to its use and is always present in the 'param_optim' vignette).

 ### 1.4.3.60 Release Notes (2020-01-29)
 
 #### New features
 
-- A digital object identifier (DOI) now allows to identify the manual of the airGR package. When you use airGR in your work, please always cite both the article and the manual. The last one allows to know the version of the package that is used in order to enhance reproducible research. The references can be displayed with the <code>citation("airGR")</code> command.

 - The field Multiplier has been added in the ErrorCrit() outputs, to indicate whether the criterion is an error (to minimise) or and efficiency (to maximise).
  This allows to provide real efficiency values in the outputs e.g. NSE[Q] instead of (-1) &times; NSE[Q].
