+### 5.9.1 (2019-05-28):
+
+* moved third party notices to `THIRD_PARTY_NOTICES.md`
+
+* Shim#require will now operate as expected.
+
+  Previously, the module interception code made the faulty assumption that a module's
+  filepath would be resolved before the module load call was invoked. This caused
+  the wrap filepath to be attributed to the modules being instrumented. This meant
+  that attempted relative require calls using Shim#require would resolved from the
+  incorrect path. The logic has been changed to keep a stack of the resolved
+  filepaths, resolving the issue.
+
+* Updates error message for license check to indicate all places that need to be
+  updated.
+
+* Shim#wrapReturn now uses ES6 proxies to wrap its methods.
+
+  This will accurately propagate look up and assignment onto the underlying wrapped
+  function, while maintaining all previous functionality.
+
+* Updated versioned test configurations to reflect current engine support.
