Jan 1, 2026January 2026 — OpenNMS/opennms: Delivered a Documentation Modernization initiative across Core and Meridian, standardizing deployment and installation guidance, and aligning naming to Core. Highlights include consolidation of deployment docs, unified JDBC driver installation guidance, and conversion of Air-Gap docs to Asciidoc. Removed references to Rocky Linux and clarified CentOS 10 deployment. Reorganized and renamed installation sections for Core, Minion, and Sentinel to install.adoc, improving consistency and onboarding. Completed related doc-build cleanups to reduce warnings and future maintenance overhead. These changes accelerate time-to-value for operators and reduce support overhead by ensuring consistent, up-to-date guidance across platforms.

Oct 1, 2025October 2025 monthly performance summary for OpenNMS/opennms focused on delivering deployment-friendly configuration, observability improvements, and stabilizing service configuration. Key outcomes include environment-variable-driven configuration templates for services and their daemons, environment-variable-based database connection settings, and JSON logging configurability, all designed to improve deployment flexibility, security, and operability in containerized and cloud environments. The effort also advanced backward compatibility and polling reliability by making the service configuration schema more flexible and integrating SNMP poller settings.
