Ex FAPI-SIG (Financial-grade API Security : Special Interest Group)
FAPI-SIG is a group whose activity is mainly supporting Financial-grade API (FAPI) and its related specifications to keycloak.
FAPI-SIG is open to everybody so that anyone can join it anytime. Nothing special need not to be done to join it. Who want to join it can only access to the communication channels shown below. All of its activities and outputs are public so that anyone can access them.
FAPI-SIG mainly treats FAPI and its related specifications but not limited to. E.g., Ecosystems employing FAPI for their API Security like UK OpenBanking, Open Banking Brasil and Australia Consumer Data Right (CDR).
Since June 2023, FAPI-SIG is evolved into OAuth SIG. OAuth SIG will mainly treats OAuth/OIDC and its related security features like FAPI 2.0 to Keycloak.
Supporting OAuth/OIDC and its related security features to Keycloak.

To ensure that every keycloak version can pass conformance tests, we check if a new Keycloak version pass conformance tests that the older Keycloak version could pass whenever the new Keycloak version is released.
We tagged the environment for every keycloak verion:
