+#### Compatiblity (BREAKING CHANGES)

+*  We have now dropped support for End-Of-Life'd versions of Python and
+   particularly old versions of the `coverage` library; if you are still using
+   Python v2.7 or v3.4, or you are using `coverage<4.1`, this library will no
+   longer be compatible starting from this release -- please pin to
+   `coveralls<2.0.0`.
