featureAutomate user provisioning with the SCIM API (preview)
featureSimplified multi-cluster high availability without external caches (preview)
featureEnhanced reverse proxy guides with blueprints for HAProxy and Traefik
featureStep-up authentication for SAML clients
securityClient-level authorization — access to external tokens is controlled per client using dedicated settings (Allow retrieve external tokens and an identity provider allow list) instead of assigning broker roles to individual users.
securityConfidential clients only — public clients are rejected, ensuring that only authenticated clients can retrieve external tokens.
securityOAuth 2.0 compliant — the endpoint uses POST and returns standard JSON responses with access_token, error, and error_description fields.
securitySession-based token storage — a new Store token in session option keeps tokens in the user session for faster access, with automatic cleanup on session expiry. Database storage remains available for persistence across sessions.
securityPolishing of existing functionality and improving configuration. Everything is now configurable in the admin UI in addition to the admin REST API.
securityLots of bugs fixed. Improved specification compliance.
securityConformance with the OpenID4VC High Assurance Interoperability Profile (HAIP). This work involves the introduction of the dedicated Keycloak experimental feature client-auth-abca for Attestation based client authentication (ABCA).
securityManagement of verifiable credentials for individual users. This involves the ability for an administrator to create a verifiable credential for a user to indicate that this user can retrieve a verifiable credential, as well as the ability for users to start issuance of a verifiable credential from…
securityPre-authorized code grant support is still experimental and was moved to the dedicated experimental feature oid4vc-vci-preauth-code
securitySupport for credential refresh interval. Administrators can now configure a separate refresh interval (vc.refresh_interval_in_seconds) in the client scope settings that controls how often wallets must refresh the credential, independent of the credential lifetime. When not explicitly set, defaults…

featureview-organizations — grants read-only access to organizations and their members (also requires view-users or Fine-Grained Admin Permissions for user visibility).
featurequery-organizations — grants the ability to search and list organizations without full view access, consistent with the query-users / query-clients / query-groups pattern.

featureCentralized Admin Console Management - New Permissions section was introduced to allow management from a single place without having to navigate to different places in the Admin Console.
featureImproved manageability - Administrators can more easily search and evaluate permissions when building a permission model for realm resources.
featureResource-Specific and Global Permissions – Permissions can be defined for individual resources (such as specific users or groups), or entire resource types (such as all users or all groups).
featureExplicit Operation Scoping – Permissions are now independent, removing hidden dependencies between operations. Administrators must assign each scope explicitly, making it easier to see what is granted without needing prior knowledge of implicit relationships.
featurePer-Realm Enablement – Fine-Grained Admin Permissions can be enabled on a per-realm basis, allowing greater control over adoption and configuration.
