| <p>2.0.0 gets rid of the “Plugin” system as their functionality was |

| <p>The Encrypt library has had a number of improvements, some for |
| encryption strength and some for performance, that has an unavoidable |
| consequence of making it no longer possible to decode encrypted data |

| transition, a new method has been added, encode_from_legacy() that |
| will decode the data with the original algorithm and return a re-encoded |
| string using the improved methods. This will enable you to easily |
| replace stale encrypted data with fresh in your applications, either on |
| the fly or en masse.</p> |
