 #### New features
 
@@ -12,7 +12,7 @@
 - `PE_Oudin()` now presents a `RunFortran` argument to run the code in Fortran or in R. The Fortran mode is the fastest. ([#62](https://gitlab.irstea.fr/HYCAR-Hydro/airgr/-/issues/62))
 - Added `RunModel_Lag()` which allows to perform a single run for the Lag model over the test period in order to run semi-distributed GR models. ([#34](https://gitlab.irstea.fr/HYCAR-Hydro/airgr/-/issues/34))
 - Added the 'sd_model' vignette to explain how to manage the use of semi-distributed GR models. ([#34](https://gitlab.irstea.fr/HYCAR-Hydro/airgr/-/issues/34))
-- Added `[` S3 method for `InputsModel` and `OutputsModel` class objects in order to extract subsets of them. ([#67](https://gitlab.irstea.fr/HYCAR-Hydro/airgr/-/issues/67))
+- Added `[` S3 method for `InputsModel` class object in order to extract subsets of it. ([#67](https://gitlab.irstea.fr/HYCAR-Hydro/airgr/-/issues/67))
