+Subject: [PATCH] stop using deprecated ElementTree methods "getchildren()" and
+ "getiterator()"
+
+Both methods were removed in Python 3.9 as mentioned in the release notes:
+
+> Methods getchildren() and getiterator() of classes ElementTree and Element in
+> the ElementTree module have been removed. They were deprecated in Python 3.2.
+> Use iter(x) or list(x) instead of x.getchildren() and x.iter() or
+> list(x.iter()) instead of x.getiterator().

+Subject: [PATCH] fix tests when using Python 3.9a6
+
+In Python 3.9a6 integer values for future flags were changed to prevent
+collision with compiler flags. We need to retrieve these at runtime so
+the test suite works with Python <= 3.8 as well as Python 3.9.
