## [6.1.0] - 2017-12-23

- Changed the token type issued by the Implicit Grant to be Bearer instead of bearer. (PR #724)

- Added validation for redirect URIs on the authorization end point to ensure exactly one redirection URI has been passed (PR #573)

## [6.0.2] - 2017-08-03

- An invalid refresh token that can't be decrypted now returns a HTTP 401 error instead of HTTP 400 (Issue #759)

## [6.0.1] - 2017-07-19

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

- If an RSA key cannot be chmod'ed to 600 then it will now throw a E_USER_NOTICE instead of an exception.

## [6.0.0] - 2017-07-01

- Breaking change: The `AuthorizationServer` constructor now expects an encryption key string instead of a public key
- Remove support for HHVM
- Remove support for PHP 5.5

## [5.1.4] - 2017-07-01

- Fixed multiple security vulnerabilities as a result of a security audit paid for by the [Mozilla Secure Open Source Fund](https://wiki.mozilla.org/MOSS/Secure_Open_Source). All users of this library are encouraged to update as soon as possible to this version or version 6.0 or greater.
	- 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.
