hermes-memory-installer: Memory Sidecar v3.5.1
Short summary
Memory Sidecar v3.5.1 focuses on operational hardening for multi-agent systems, solving production friction like dangling connections, unbounded retries, and inconsistent transaction windows. Core changes include session-scoped graceful shutdown with ephemeral tokens and bounded exponential backoff with per-request jitter to prevent retry storms. The agent-agnostic layer maintains compatibility across frameworks with a new hardening profile for automated defaults.
- •Session-scoped graceful shutdown with ephemeral tokens prevents orphaned write buffers and ensures deterministic cleanup
- •Bounded exponential backoff with per-request jitter eliminates retry storms when storage backends recover from outages
- •Agent-agnostic design supports LangChain, Python workers, and Node services with unified retry and transaction policies
