Log Message:
Update to 1.5.0 based on PR 50399 by derouiche. Now with python 3 support.

New in version 1.5.0
====================

This release fixes critical memory leaks in common code paths introduced in
1.4.2. Highly recommended.

New in version 1.4.0
--------------------

Brace yourself, Python 3.x support has come!

Thanks to everybody involved in this project; this release involves less
authors but **a lot** more work per person. Thanks especially to Harvey Falcic
for the work he put in, without which there wouldn't be any Python 3.x support.
Also thanks to Sergey Pashinin for the initial stab at the problem.

Other than that, we had miscellaneous bug fixes, testing improvements, and
documentation updates.

Last but not least I would like to ask for your support in this project, either
by helping out with development, testing, documentation or anything at all; or
simply by donating some `magic internet money`__ to the project's Bitcoin
address `12dveKhqiJWCY8zXT4kaHdHELXPeGAUo9h`__
