+- `array_labels`: Allow normal arrays to be passed for which the process returns the indices. [#243](https://github.com/Open-EO/openeo-processes/issues/243)

 ### Removed
 
 - Removed the explict schema for `raster-cube` in the `data` parameters and return values of `run_udf` and `run_udf_externally`. It's still possible to pass raster-cubes via the "any" data type, but it's discouraged due to scalability issues. [#285](https://github.com/Open-EO/openeo-processes/issues/285)
