+## Note on ECMA5cript 5 JSON API compatibility
+
+Version 0.3 and below explicitly depended on the [jquery-json](https://code.google.com/p/jquery-json/) library to define the `$.evalJSON` and `$.toJSON` methods. This requirement has been replaced in subsequent versions by a dependency on the JSON parsing and serialization API defined in ECMAScript5 ([described thoroughly here](http://ejohn.org/blog/ecmascript-5-strict-mode-json-and-more/)).
+
+When upgrading from 0.0.3, you must do one of the following:
+
+1. Replace your usage of jquery-json with a library that defines `JSON.parse` and `JSON.stringify` for browsers that do not support them natively. json2.js from the [JSON-js](https://github.com/douglascrockford/JSON-js) library is a good choice.
+2. Provide your own implementations of those methods or otherwise deal on your own with browsers that do not support them natively.
