- bug fixed in `PrepGR()` and by consequence in `ShinyGR()` when the dataset given to the `ObsDF` argument is a `tibble` object. ([#49](https://gitlab.irstea.fr/HYCAR-Hydro/airgrteaching/-/issues/49))
#### User-visible changes
- in order to avoid duplicated warning messages, the use of the `.onAttach()` command has been removed from the `ShinyGR()` function, because it is already call from the `dyplot()` function which is use in `ShinyGR()`. ([#50](https://gitlab.irstea.fr/HYCAR-Hydro/airgr/-/issues/50))
- the 'Model diagram' plot exported from the GUI launched by `ShinyGR()` has been resized to avoid to wide title when the the parameter values are large. ([#54](https://gitlab.irstea.fr/HYCAR-Hydro/airgr/-/issues/54))
- the deprecated icon names from 'Font Awesome' have been updated to avoid warning messages when the `ShinyGR()` function is used. ([#51](https://gitlab.irstea.fr/HYCAR-Hydro/airgr/-/issues/51))
#### Version control and issue tracking
- the CI/CD runner now uses a R docker image. ([#55](https://gitlab.irstea.fr/HYCAR-Hydro/airgr/-/issues/55))
#### CRAN-compatibility updates
- The `FUN_CRIT` deprecated argument (since 'airGR' 1.2.13.16) has been removed from the use of `Calibration()` call by the `CalGR()` function. ([#56](https://gitlab.irstea.fr/HYCAR-Hydro/airgr/-/issues/56))
- bug fixed in the GUI launched by `ShinyGR()`, it is possible to the export the GR2M model diagram PNG file again. ([#40](https://gitlab.irstea.fr/HYCAR-Hydro/airgrteaching/-/issues/40))
- bug fixed in `ShinyGR()` when the date column of `ObsDF` has another name as 'DatesR'. ([#38](https://gitlab.irstea.fr/HYCAR-Hydro/airgrteaching/-/issues/38))
