 NEXT RELEASE
 ------------
 
+Breaking changes:
+
+* ``common`` role:
+
+  * Added separate parameter (``pip_check_requirements_py3``) for
+    specifying dedicated Python 3 virtual environment package
+    requirements used for package upgrade checks on (other
+    user-provided) Python 3 virtual environments. If the existing
+    ``pip_check_requirements`` parameter has been overridden, the new
+    parameter will most likely need to be overridden in your site
+    configuration as well. Take note that the new requirements will
+    differ between Debian Jessie and Debian Stretch due to differnece
+    in Python 3 minor version releases.
