`r.mask` got new `vector`, `layer`, `cats`, and `where` options in r54302.
The `input` option has been renamed to `raster`.
If you want to create a MASK from a raster map, you now need to set the
raster option. If you want to create a MASK from a vector map, you now
need to set the vector option. Only vector areas will be considered for
creating a MASK from a vector.
When a MASK is created from a raster, the extents and resolution of the
raster map are used because r.reclass is used (that's the unchanged
default behaviour as in GRASS 6), but when a MASK is created from a
vector, the current region settings are used.
