+Changes in Version 4.0.1
+-------------------------
+
+Issues Resolved
+...............
+
+Version 4.0.1 fixes a number of bugs:
+
+- Fixed a bug that prevented :meth:`bson.json_util.loads` from
+  decoding a document with a non-string "$regex" field (`PYTHON-3028`_).
+- Fixed a bug where a client may select a hidden/ghost or not yet initialized
+  replica set member leading to unexpected "connection pool paused" errors
+  (`PYTHON-3027`_).
+
+See the `PyMongo 4.0.1 release notes in JIRA`_ for the list of resolved issues
+in this release.
