Please also refer to the changelog notes for 1.0.0-alpha1, 1.0.0-alpha2, 1.0.0-beta1, and 1.0.0-beta2.

1.0.0-beta2

• BREAK: Add toArray() to ResourceOwnerInterface.
• Always attempt to parse responses as JSON and fallback on failure.
• Add dot notation support to access token resource owner ID.
• Use the Bearer authorization header for the generic provider.
• Documentation updates.

1.0.0-beta1

• API for 1.0 is now frozen!
• BREAK: Convert all uses of "User" to "ResourceOwner" to more closely match the OAuth 2.0 specification.
• BREAK: Rename StandardProvider to GenericProvider.
• BREAK: Move access token creation to the AbstractProvider. It was previously handled in the AbstractGrant.
• FIX: Add Content-Type header with value of application/x-www-form-urlencoded to the request header when retrieving access tokens. This adheres to the OAuth 2.0 specification and fixes issues where certain OAuth servers expect this header.
• Enhanced json_encode() serialization of AccessToken; when using json_encode() on an AccessToken, it will return a JSON object with these properties: access_token, refresh_token, and expires_in.

1.0.0-alpha2

• BREAK: Renamed AbstractProvider::ACCESS_TOKEN_METHOD_GET to AbstractProvider::METHOD_GET.
• BREAK: Renamed AbstractProvider::ACCESS_TOKEN_METHOD_POST to AbstractProvider::METHOD_POST.
• BREAK: Renamed AbstractProvider::prepareUserDetails() to AbstractProvider::createUser().
• BREAK: Renamed AbstractProvider::getUserDetails() to AbstractProvider::getUser().
• BREAK: Removed $token parameter from AbstractProvider::getDefaultHeaders().
• BREAK: Modify AbstractProvider::getBaseAccessTokenUrl() to accept a required array of parameters, allowing providers the ability to vary the access token URL, based on the parameters.
• Removed newline characters from MAC Authorization header.
• Documentation updates, notably:
  • Moved list of providers to README.PROVIDERS.md.
  • Moved provider creation notes to README.PROVIDER-GUIDE.md.

1.0.0-alpha1

This release contains numerous BC breaks from the 0.x series. Please note these breaks and refer to the upgrade guide.

• BREAK: Requires PHP 5.5.0 and greater.
• BREAK: All providers have been moved to separate repositories, one for each provider.
• BREAK: All public properties have been set as protected or private and getters/setters have been introduced for access to these properties.
• BREAK: The Provider\ProviderInterface has been removed. Please extend from and override Provider\AbstractProvider.
• BREAK: The Entity\User has been removed. Providers should implement the Provider\UserInterface and provide user functionality instead of expecting it in this base library.
• BREAK: The Grant\GrantInterface has been removed. Providers needing to provide a new grant type should extend from and override Grant\AbstractGrant.
• A generic Provider\StandardProvider has been introduced, which may be used as a client to integrate with most OAuth 2.0 compatible servers.
• A Grant\GrantFactory has been introduced as a means to register and retrieve singleton grants from a registry.
• Introduced traits for bearer and MAC authorization (Tool\BearerAuthorizationTrait and Tool\MacAuthorizationTrait), which providers may use to enable these header authorization types.

0.12.1

• FIX: Scope separators for LinkedIn and Instagram are now correctly a single space

0.12.0

• BREAK: LinkedIn Provider: Default scopes removed from LinkedIn Provider. See "Managing LinkedIn Scopes" in the README for information on how to set scopes. See #327 and #307 for details on this change.
• FIX: LinkedIn Provider: A scenario existed in which publicProfileUrl was not set, generating a PHP notice; this has been fixed.
• FIX: Instagram Provider: Fixed scope separator.
• Documentation updates and corrections.
