-### Version 0.5.3 (unreleased)
-- Fixes #134: Add `xr.Dataset` as input type for appropriate modules.
-  Most public functions now transparently accept `xr.Dataset` in addition
-  to `xr.DataArray`. Single-input functions (slope, aspect, curvature,
-  hillshade, focal.mean, all classification functions, proximity/allocation/
-  direction) iterate over data variables and return a Dataset. Multi-input
-  functions (all multispectral indices) accept a Dataset with band-name
-  keyword arguments. `zonal.stats` computes per-variable statistics and
-  returns a merged DataFrame with prefixed columns.
