+### Breaking Changes
+
+-   `routr` uses native `URLSearchParams` instead of `query-string`
+    library internally. If you need to support old browsers, you can
+    either add a `URLSearchParams` polyfill or inject `query-string`
+    when instantiating `routr`:
+
+```js
+router = new Routr(routes, {
+    queryLib: require('query-string'),
+});
+```
