+- update to version 0.12.3:
+ - New functions/methods:
+  - New methods :py:meth:`Dataset.to_stacked_array` and
+    :py:meth:`DataArray.to_unstacked_dataset` for reshaping Datasets of variables
+    with different dimensions
+    (:issue:`1317`).
+    This is useful for feeding data from xarray into machine learning models,
+    as described in :ref:`reshape.stacking_different`.
+ - Enhancements:
+  - Support for renaming ``Dataset`` variables and dimensions independently
+    with :py:meth:`~Dataset.rename_vars` and :py:meth:`~Dataset.rename_dims`
+    (:issue:`3026`).
+  - Add ``scales``, ``offsets``, ``units`` and ``descriptions``
+    attributes to :py:class:`~xarray.DataArray` returned by
+    :py:func:`~xarray.open_rasterio`. (:issue:`3013`)
+ - Bug fixes:
+  - Resolved deprecation warnings from newer versions of matplotlib and dask.
+  - Compatibility fixes for the upcoming pandas 0.25 and NumPy 1.17 releases.
+  - Fix summaries for multiindex coordinates (:issue:`3079`).
+  - Fix HDF5 error that could arise when reading multiple groups from a file at
+    once (:issue:`2954`).
