ReleasePort's take

Moderate signal
editorial:auto 13d

v1.37.3 prevents shutdown hangs via buffered close signal channels and adds basic auth support for Raft cluster endpoints.

Why it matters: Prevents shutdown hangs that delay node restarts; critical for availability. Adds basic auth for Raft cluster endpoints, tightening security. Operators should upgrade for operational reliability and improved cluster security.

Summary
