+BREAKING CHANGES:
+* Support for Python 3.6 has been dropped.  This is forced by incompatibilities
+  discovered with the latest version of pytest and because dependencies like
+  dateutil and ruamel-yaml-clib no longer support Python 3.6.  Support for
+  Python 3.7 is tepid.  While pytest is still working with Python 3.7, other
+  dependencies are no longer supporting Python 3.7; however, the extensive
+  tests for yamlpath show no issues with them, so far.

 Bug Fixes:
 * Fixed issue #220 reported by https://github.com/abramov-oleg wherein novel

 This project requires [Python](https://www.python.org/) 3.  It is rigorously
