March 2026: Delivered two feature-focused documentation updates in ClickHouse/clickhouse-docs aimed at improving observability, reliability, and developer onboarding. Key outcomes include logging improvements (separate stdout and stderr levels with the default JS client log level documented as WARN) and extensive documentation enhancements for networking, configuration, and reliability (curl -i visibility for HTTP headers, guidance on long-running queries and network effects, multi-instance client configuration steps, ESLint no-floating-promises guidance, keep_alive.idle_socket_ttl clarification, troubleshooting practices, and typo fixes). These changes were implemented through a series of commits across the two features (notable ones include b882dda0b944e87f1419114e2abb2559475f3944, af5565ced6abdd0169eb36f0bd2a0caacf0f7a5f, 4330c7f3b5a51243e6aa294437762d363bbb4ed9, 75195938ffe55aba05bc6ec8e6318782c7346ead, 70f21cd6f58aaa32cb8b38b395253bdd467e12a8, ce4e96a4d08f3613724f11c6de2929304b4554a9, c3735068d6c2b81235358374af5205bf830ad011, 4ee6939e7f0434540e4c03685a698b0435bcfd07, 9abcc8347f7fa14683e38daf898e21a1e5c2a1dd, bc0bb758c9236a6102cecf120efa0f356a451311).
