January 2026 — AzureAD/microsoft-authentication-library-common-for-android: Delivered security-focused enhancements to the brokered authentication flow and web authentication support, along with targeted debugging and testability improvements. Key updates include upgrading the broker protocol to version 20.0, removal of an unnecessary state parameter, addition of extraTokenBodyParameters, and introducing a new telemetry span name. Implemented a feature-flagged option to remove certificate chain validation (with a re-enable path) and added the OneAuth test app thumbprint to the debug allowlist for SSOToken/WebApps API. Introduced WebAppsNonce as a new nonce claim in JWT requests for web authentication, with corresponding tests. These changes strengthen authentication reliability, improve security posture, and enhance observability and debugging capabilities.
