------------------
* Suggest ``assertAlmostEqual(a, b, x)`` for ``round()`` expressions like in
``assertEqual(a, round(b, x))`` and ``assertAlmostEqual(a, round(b, x))``
(and similar for ``assertNotEqual()`` and ``assertNotAlmostEqual()``.
* Recognize ``assertAmostEquals()`` and ``assertNotAlmostEquals()`` as aliases
for ``assertAlmostEqual()`` and ``assertNotAlmostEqual()``.
* Drop Python 3.4 as a supported version since it has been officially retired.
