 ### Added
 - Formatting Spotless Groovy import order [#960](https://github.com/ie3-institute/PowerSystemDataModel/issues/960)
 - Implementing missing typical methods in `Try` [#970](https://github.com/ie3-institute/PowerSystemDataModel/issues/970)
+- Added log warning when using `SwitchInputs` with `parallelDevices` parameter [#840](https://github.com/ie3-institute/PowerSystemDataModel/issues/840)
 
 ### Fixed
 - Fixed Couchbase integration tests that randomly failed [#755](https://github.com/ie3-institute/PowerSystemDataModel/issues/755)
