+# Changelog
+
+## 3.2 (released 2014-04-16)
+
+* Added the ability to change the algorithm that is used to generate the token strings (Issue #151)
+
+## 3.1.2 (released 2014-02-26)
+
+* Support Authorization being an environment variable. [See more](http://fortrabbit.com/docs/essentials/quirks-and-constraints#authorization-header)
+
+## 3.1.1 (released 2013-12-05)
+
+* Normalize headers when `getallheaders()` is available (Issues #108 and #114)
+
+## 3.1.0 (released 2013-12-05)
+
+* No longer necessary to inject the authorisation server into a grant, the server will inject itself
+* Added test for 1419ba8cdcf18dd034c8db9f7de86a2594b68605
+
+## 3.0.1 (released 2013-12-02)
+
+* Forgot to tell TravisCI from testing PHP 5.3
+
+## 3.0.0 (released 2013-12-02)
+
+* Fixed spelling of Implicit grant class (Issue #84)
+* Travis CI now tests for PHP 5.5
+* Fixes for checking headers for resource server (Issues #79 and #)
+* The word "bearer" now has a capital "B" in JSON output to match OAuth 2.0 spec
+* All grants no longer remove old sessions by default
+* All grants now support custom access token TTL (Issue #92)
+* All methods which didn't before return a value now return `$this` to support method chaining
+* Removed the build in DB providers - these will be put in their own repos to remove baggage in the main repository
+* Removed support for PHP 5.3 because this library now uses traits and will use other modern PHP features going forward
+* Moved some grant related functions into a trait to reduce duplicate code
+
+## 2.1.1 (released 2013-06-02)
+
+* Added conditional `isValid()` flag to check for Authorization header only (thanks @alexmcroberts)
+* Fixed semantic meaning of `requireScopeParam()` and `requireStateParam()` by changing their default value to true
+* Updated some duff docblocks
+* Corrected array key call in Resource.php (Issue #63)
+
+## 2.1 (released 2013-05-10)
+
+* Moved zetacomponents/database to "suggest" in composer.json. If you rely on this feature you now need to include " zetacomponents/database" into "require" key in your own composer.json. (Issue #51)
+* New method in Refresh grant called `rotateRefreshTokens()`. Pass in `true` to issue a new refresh token each time an access token is refreshed. This parameter needs to be set to true in order to request reduced scopes with the new access token. (Issue #47)
+* Rename `key` column in oauth_scopes table to `scope` as `key` is a reserved SQL word. (Issue #45)
+* The `scope` parameter is no longer required by default as per the RFC. (Issue #43)
+* You can now set multiple default scopes by passing an array into `setDefaultScope()`. (Issue #42)
+* The password and client credentials grants now allow for multiple sessions per user. (Issue #32)
+* Scopes associated to authorization codes are not held in their own table (Issue #44)
+* Database schema updates.
+
+## 2.0.5 (released 2013-05-09)
+
+* Fixed `oauth_session_token_scopes` table primary key
+* Removed `DEFAULT ''` that has slipped into some tables
+* Fixed docblock for `SessionInterface::associateRefreshToken()`
+
+## 2.0.4 (released 2013-05-09)
+
+* Renamed primary key in oauth_client_endpoints table
+* Adding missing column to oauth_session_authcodes
+* SECURITY FIX: A refresh token should be bound to a client ID
+
+## 2.0.3 (released 2013-05-08)
+
+* Fixed a link to code in composer.json
+
+## 2.0.2 (released 2013-05-08)
+
+* Updated README with wiki guides
+* Removed `null` as default parameters in some methods in the storage interfaces
+* Fixed license copyright
+
+## 2.0.0 (released 2013-05-08)
+
+**If you're upgrading from v1.0.8 there are lots of breaking changes**
+
+* Rewrote the session storage interface from scratch so methods are more obvious
+* Included a PDO driver which implements the storage interfaces so the library is more "get up and go"
+* Further normalised the database structure so all sessions no longer contain infomation related to authorization grant (which may or may not be enabled)
+* A session can have multiple associated access tokens
+* Induvidual grants can have custom expire times for access tokens
+* Authorization codes now have a TTL of 10 minutes by default (can be manually set)
+* Refresh tokens now have a TTL of one week by default (can be manually set)
+* The client credentials grant will no longer gives out refresh tokens as per the specification
+
+## 1.0.8 (released 2013-03-18)
+
+* Fixed check for required state parameter
+* Fixed check that user's credentials are correct in Password grant
+
+## 1.0.7 (released 2013-03-04)
+
+* Added method `requireStateParam()`
+* Added method `requireScopeParam()`
+
+## 1.0.6 (released 2013-02-22)
+
+* Added links to tutorials in the README
+* Added missing `state` parameter request to the `checkAuthoriseParams()` method.
+
+## 1.0.5 (released 2013-02-21)
+
+* Fixed the SQL example for SessionInterface::getScopes()
+
+## 1.0.3 (released 2013-02-20)
+
+* Changed all instances of the "authentication server" to "authorization server"
+
+## 1.0.2 (released 2013-02-20)

+A standards compliant [OAuth 2.0](http://tools.ietf.org/wg/oauth/draft-ietf-oauth-v2/) authorization server and resource server written in PHP.
 
 ## Package Installation
 
-The framework is provided as a Composer package which can be installed by adding the package to your composer.json file:
+The framework is provided as a Composer package which can be installed by adding the package to your `composer.json` file:
 
 ```javascript
 {
-	"require": {  
-		"lncd\Oauth2": "*"  
+	"require": {
+		"league/oauth2-server": "3.*"
 	}
 }
 ```
 
-## Package Integration
+### Framework Integrations
 
-Check out the [wiki](https://github.com/lncd/OAuth2/wiki)
-
-## Current Features
-
-### Authentication Server
-
-The authentication server is a flexible class that supports the standard authorization code grant.
-
-### Resource Server
-
-The resource server allows you to secure your API endpoints by checking for a valid OAuth access token in the request and ensuring the token has the correct permission to access resources.
-
-
-
-
-## Future Goals
-
-### Authentication Server
-
-* Support for [JSON web tokens](http://tools.ietf.org/wg/oauth/draft-ietf-oauth-json-web-token/).
-* Support for [SAML assertions](http://tools.ietf.org/wg/oauth/draft-ietf-oauth-saml2-bearer/).
-
-### Client support
-
-* Merge in https://github.com/philsturgeon/codeigniter-oauth2
+* [Laravel Service Provider](https://packagist.org/packages/lucadegasperi/oauth2-server-laravel) by @lucadegasperi
+* [Laravel Eloquent implementation](https://github.com/ScubaClick/scubaclick-oauth2) by @ScubaClick (under development)
 
 ---
 
-This code will be developed as part of the [Linkey](http://linkey.blogs.lincoln.ac.uk) project which has been funded by [JISC](http://jisc.ac.uk) under the Access and Identity Management programme.
+The library features 100% unit test code coverage. To run the tests yourself run `phpunit` from the project root.

+
+[![Build Status](https://travis-ci.org/thephpleague/oauth2-server.png?branch=develop)](https://travis-ci.org/thephpleague/oauth2-server) [develop]
+
+
+## Current Features
+
+### Authorization Server
+
+The authorization server is a flexible class and the following core specification grants are implemented:
+
+* authorization code ([section 4.1](http://tools.ietf.org/html/rfc6749#section-4.1))
+* refresh token ([section 6](http://tools.ietf.org/html/rfc6749#section-6))
+* client credentials ([section 2.3.1](http://tools.ietf.org/html/rfc6749#section-2.3.1))
+* password (user credentials) ([section 4.3](http://tools.ietf.org/html/rfc6749#section-4.3))
+
+An [overview of the different OAuth 2.0 grants](https://github.com/thephpleague/oauth2-server/wiki/Which-OAuth-2.0-grant-should-I-use%3F) can be found in the [wiki].
+
+### Resource Server
+
+The resource server allows you to secure your API endpoints by checking for a valid OAuth access token in the request and ensuring the token has the correct scope(s) (i.e. permissions) to access resources.
+
+### Custom grants
+
+Custom grants can be created easily by implementing an interface. Check out the [custom grant guide](https://github.com/thephpleague/oauth2-server/wiki/Creating-custom-grants).
+
