 Release Notes
 =============
 
+- 2022-03-04:
+    - Synchronize configure and configure.bat scripts for sanity
+    - Update CI operating system support with latest Azure OS images
+    - Streamline utility scripts in etc/scripts/ to create, fetch and manage third-party dependencies
+      There are now fewer scripts. See etc/scripts/README.rst for details
+
 - 2021-09-03:
     - ``configure`` now requires pinned dependencies via the use of ``requirements.txt`` and ``requirements-dev.txt``
     - ``configure`` can now accept multiple options at once
