I'm proud to announce the release of spring-security-pac4j v1.3.0 based on Spring Security v4: https://github.com/pac4j/spring-security-pac4j

The spring-security-pac4j library is a Spring Security extension which makes multi-protocol support really easy and consistent for OAuth, CAS, SAML, OpenID... It successfully replaces the spring-security-cas, spring-security-oauth, spring-security-saml2-core, spring-security-openid and Spring Social libraries and also adds missing protocols (like OpenID Connect and Google App Engine).
