April 2026 (2026-04) - OpenTDF SDK delivered a Unified Authentication Interceptor Pattern, unifying authentication across OpenTDF and PlatformClient with backward compatibility to AuthProvider. The new interceptor-based path improves security and token management, reduces internal complexity, and accelerates readiness for 1.0 by centralizing auth handling at the Client boundary. Key changes include new interceptors (authTokenInterceptor, authTokenDPoPInterceptor, authProviderInterceptor), the AuthConfig union type, and threading interceptors through core layers (TDF3Client, access, policy, Encrypt/Decrypt). Documentation was updated to promote interceptor-first usage and provide migration guidance. Business value realized: streamlined, secure, and future-proof authentication with fewer edge cases and easier migration.

April 2025: Delivered backward-compatible enhancements and CI/documentation improvements across opentdf/web-sdk and opentdf/platform. Key changes include legacy TDF 4.2.2 hex-encoded signature hash support, a CI update to Keycloak 24.0.5 for more current testing, and a clarified protobuf generation prerequisite in the platform docs. These changes reduce customer upgrade risk, improve test reliability, and streamline protobuf workflow.
