+## Breaking changes
+
+- The HTML files have switched from the now deprecated `@babel/polyfill`
+    to `core-js-bundle` and `regenerator-runtime` replacements. If you
+    have not modified the HTML and are updating via npm, this change
+    should have no effect. (`@babel/polyfill` is still required through
+    some of the dependencies, but this is expected to eventually change.)
+- If you are running build files, you will now need at least Node 8.5
