+            [Python] Patch #694 - Fix package import regressions introduced in swig-3.0.9.
+
+            1) The code in 3.0.9 did not fall back to 'import _foo' if 'import bar._foo' failed
+            (assuming bar.foo was the main module). Every place _foo is imported now first tries
+            it from the package where foo was found and if that fails tries _foo as a global module.
+
+            2) The separate block of python code that injected code to pull in the attributes
+            from _foo when -builtin is used made use of the -py3 switch to either do
+            'from ._foo import *' or "from _foo import *". This block of code no longer does this
+            and instead checks the python version at runtime to switch between the two syntaxes.
