Updated bundled OpenSSL 3.0.14 → 3.0.21, addressing CVE-2026-45447 and related upstream CVEs (defense-in-depth; not exploitable in normal Datasentinel usage).
Third-party dependencies have also been updated to address known security vulnerabilities.
Agentless monitoring Connections pointing to an unreachable instance can now be deleted from the UI and the API. Previously the dispatcher's delete request timed out against an agent blocked on hung database I/O. The agent completed the deletion while the dispatcher aborted, leaving its instance pool out of sync and the connection stuck. The dispatcher now cleans up its own state whether the agent times out or answers 404 – Connection not found.
