+    Tinyipa is the base image for testing Ironic Python Agent.
+    In the effort of moving toward a full Python 3 friendly environment,
+    with this patch we start building the tinyipa image with Python 3 by
+    default.
+other:
+  - Change the Python default version used to build and run the Ironic
+    Python Agent in the Tiny Core based image to 3.6.
