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.
- Added a section 'param_optim' vignette to explain how to manage with multiobjective optimization using the 'CaRamel' package. ([#61](https://gitlab.irstea.fr/HYCAR-Hydro/airgr/-/issues/61))
#### Major user-visible changes
-`Imax()` now returns an error message when `IndPeriod_Run` doesn't select 24 hours by day, instead of `numeric(0)`. ([#92](https://gitlab.irstea.fr/HYCAR-Hydro/airgr/-/issues/92))
#### Minor user-visible changes
- Fixed warning returned by GCC Fortran when compiling `frun_GR5H.f90`. ([#93](https://gitlab.irstea.fr/HYCAR-Hydro/airgr/-/issues/93))
#### CRAN-compatibility updates
- Coerce `POSIXlt` dates into character in `RunModel_GR1A()` example and in `SeriesAggreg()` tests in order to avoid bad subsetting on time series due to mixing UTC and local time on macOS flavors. ([#94](https://gitlab.irstea.fr/HYCAR-Hydro/airgr/-/issues/94))
