May 2026 — nesquena/hermes-webui: API Payload Optimization for Paginated Session Data. Refactored the API to trim session-level tool call payloads during paginated loads and added _tool_calls_for_message_window to filter tool calls by message index within the visible window. This reduces unnecessary historical tool call data, improves payload efficiency, and enhances UI performance for long-running sessions. Commits: d920d4222af3d0f307c4ceadb1a94b88cba8dd1b.

October 2025: Focused on strengthening observability for Grafana Tempo by introducing block-size logging for head block cuts in both the ingester and livestore, with refined log messages to improve debugging under memory pressure and to track flush operations. These changes provide richer runtime diagnostics, enabling faster issue diagnosis, better capacity planning, and more reliable performance under memory constraints.
