To address feedback from the security release the following change has been made:

## [6.0.0] - 2017-07-01

- Breaking change: The `AuthorizationServer` constructor now expects an encryption key string instead of a public key

## [5.1.4] - 2017-07-01

	- It is recommended on each `AuthorizationServer` instance you set the `setEncryptionKey()`. This will result in stronger encryption being used. If this method is not set messages will be sent to the defined error handling routines (using `error_log`). Please see the examples and documentation for examples.
