well, it's quite explicitly stated that print has to look like in Py3.
In the release notes:

       There are some important changes:

       - Any print statements must now use python 3 syntax of "print()"

the bugfix was more obscure and related to an automatic import of
print_function, which wasn't necessarily a good idea.
