== SAML Artifact binding in server to client communication

Keycloak now supports communication with clients using SAML _Artifact_ binding. A new `Force Artifact Binding` option
was introduced in the client configuration, that forces communication with the client using artifact messages. For more
details proceed to link:{adminguide_link}#_client-saml-configuration[{adminguide_name}]. Please note, that with
this version, Keycloak SAML client adapter does NOT support Artifact binding.

== Support PKCE for identity brokering

Keycloak can now leverage PKCE when brokering to an external OpenID Connect IdP.

== Default roles processing improvement

Default roles are now internally stored as composite roles of a new role usually named `default-roles-${realmName}`. Instead of assigning
both realm and all client default roles directly to newly created users or users imported through Identity Brokering, just the role is
assigned to them and the rest of default roles are assigned as effective roles. This change improves performance of default roles processing,
especially with larger number of clients, because it is no longer necessary to go through all clients.
