     * Fixed a bug in HRA where the model would error when all exposure and
       consequence criteria were skipped for a single habitat. The model now
       correctly handles this case. https://github.com/natcap/invest/issues/1250
+    * Tables in the .xls format are no longer supported. This format was
+      deprecated by ``pandas``. (`#1271 <https://github.com/natcap/invest/issues/1271>`_)
 * Scenic Quality
     * The Scenic Quality model will now raise an error when it encounters a
       geometry that is not a simple Point.  This is in line with the user's
       guide chapter.  https://github.com/natcap/invest/issues/1245
