March 2026 highlights for repository keycloak/keycloak: Implemented security-enhanced OpenID Connect discovery via ServerMetadataResource by making WellKnown providers controllable via a new availability toggle with default behavior preserving the prior exposure. Updated provider factories to honor exposure decisions and added tests ensuring that the .well-known/openid-configuration is not exposed by default (HTTP 404 when accessed with incorrect settings). Refactored alias resolution by introducing WellKnownProviderUtil.resolveFromAlias(..) and aligned ServerMetadataResource and RealmsResource to use it for consistent, prioritized alias handling. Cleaned up API surface with renamed methods (getWellKnownPreflight / getWellKnown) and introduced wellKnownProviderUrl while deprecating the old calls. Strengthened code quality and test coverage to reduce regressions and improve maintainability.
