+- **scripts** Drop the `gdxrrw`/`gdx` R dependency from REMIND scripts; GDX writes now use `gamstransfer`-based `quitte::write.gdx`
+    [[#2485](https://github.com/remindmodel/remind/pull/2485)]
 
 ### fixed
 - **scripts** Fix call to harmonization and infilling console entry point in  `climateAssessmentInterimRun.R`

 Model dependencies **must be publicly available** and should be Open Source.
 Development aim is to rather minimize than expand dependencies on non-free
 and/or non open source software. That means that besides currently existing
