-# Current version
+# Version 0.9.0
+
+## Major Features and Improvements
+
+* Adding functionality for handling structured data.
+
+## Bug Fixes and Other Changes
+
+* StructStatistics.common_statistics changed to
+  StructStatistics.common_stats to agree with Facets.
+
+## Breaking changes
+
+* The change from StructStatistics.common_statistics to 
+  StructStatistics.common_stats may break code that had this field set and
