March 2025 monthly summary for keycloak/keycloak focusing on architectural refactors, cleanup, and test improvements that drive security, reliability, and developer velocity: a major OAuthClient refactor consolidated token operations into AbstractOAuthClient, comprehensive cleanup removed deprecated methods from OAuthClient, and integration work completed across OAuthClient and AbstractOAuthClient for token exchange, state/nonce, DPoP, PKCE, and claims with obsolete fields removed. Enhancements to testing infrastructure include adding a basic TestApp to the new testsuite, reusing HttpClient across tests, and introducing UUID-based event matching plus simplified time offset checks. Login configurability was expanded by making kcAction, uiLocales, maxAge, and prompt configurable at login. Multiple stability bugs were addressed in test lifecycle and resource injection, including rollback attribute handling, rollback state reset, and test class ordering by server configuration. These changes collectively improve security posture, reduce maintenance burden, and accelerate feature delivery with more deterministic tests and configurable login experiences.
