+Changes in Version 3.7.2
+------------------------
+
+Version 3.7.2 fixes a few issues discovered since the release of 3.7.1.
+
+- Fixed a bug in retryable writes where a previous command's "txnNumber"
+  field could be sent leading to incorrect results.
+- Fixed a memory leak of a few bytes on some insert, update, or delete
+  commands when running against MongoDB 3.6+.
+- Fixed a bug that caused :meth:`pymongo.collection.Collection.ensure_index`
+  to only cache a single index per database.
+- Updated the documentation examples to use
+  :meth:`pymongo.collection.Collection.count_documents` instead of
+  :meth:`pymongo.collection.Collection.count` and
+  :meth:`pymongo.cursor.Cursor.count`.
