+
+### Changes
+
+* **BREAKING CHANGE** - Fix [#94]: Long options no longer bind
+  implicit arguments through substring matches.\
+  Before this change, the program `usage: foo --foo=<arg>` allowed
+  passing in `--foobar`, which would yield `--foo => "bar"`, which
+  was found to have undesirable side-effects as explored in [#94].
+  Since changing this behavior has not only follow on effects for
+  users of neodoc, but also users of users, a major version bump
+  was necessary.
