- added explanation of the use of the GR5H model in the `PrepGR()` help page. ([#41](https://gitlab.irstea.fr/HYCAR-Hydro/airgr/-/issues/41))
- the text relating to the GR2M model in the 'GUI Help' image displayed by the GUI launched by `ShinyGR()` is corrected. ([#42](https://gitlab.irstea.fr/HYCAR-Hydro/airgr/-/issues/42))
- replace the use of `class()` by `inherits()` in order to test the classes of inputs in all functions. ([#45](https://gitlab.irstea.fr/HYCAR-Hydro/airgr/-/issues/45))
- when the package is loaded or when the `dyplot()` and the `ShinyGR()` function are used, a message warns the users if they use a version of 'htmlwidgets' < 1.5.2.9000. The latest version of this package, available on GitHub, avoids troubles with the use of dynamic graphics of the 'dygraphs' package (called by the `dyplot*()` and the `ShinyGR()` functions) ([#5](https://gitlab.irstea.fr/HYCAR-Hydro/airgrteaching/-/issues/5))
