 # Changelog
 
-## 6.0.0 (released 2017-07-01)
+## 5.1.5 (released 2017-07-11)
 
-* Breaking change: The `AuthorizationServer` constructor now expects an encryption key string instead of a public key
+To address feedback from the security release the following two changes have been made:
-* Remove support for HHVM
+
-* Remove support for PHP 5.5
+* If an RSA key cannot be `chmod`'ed to 600 then it will now throw a `E_USER_NOTICE` instead of an exception.
+* Not using the new encryption key method on `AuthorizationServer` will set throw an `E_USER_DEPRECATED` message instead of an error.
 
 ## 5.1.4 (released 2017-07-01)
