- Added new features such as GCP Cloud KMS managed keys, LDAP secrets engine, OCSP responder for PKI, Redis DB and ElastiCache plugins, Transform BYOK, HCP self‑managed node support, UI Okta challenge, and secret/auth plugin multiplexing.
- Extended API responses to include deprecation status and version metadata for plugins, auth methods, mounts, and secrets; introduced a detailed flag for plugin list and sys/loggers endpoints.
- Strengthened deprecation enforcement: pending‑removal auth and secret engines now error on enable, terminated licenses block upgrades, and commands now emit warnings/errors for deprecated or builtin mounts.
