Prometheus has seen significant advancements since PromCon 2019, with updates including a new React-based UI in version 2.14, metadata API enhancements in 2.15, and the introduction of ACID database isolation in 2.17. Subsequent versions focused on improvements such as memory footprint reduction by 50% in 2.19 and native support for service discovery in 2.20. The project continues to evolve with a focus on metadata utilization, workflow changes, and backfilling support strategies. Prometheus has also adjusted its development approach due to COVID-19, opting for shorter, more frequent virtual dev summits to manage its growing backlog. Efforts are underway to improve documentation, with plans to restructure it into distinct user manuals, reference sections, and guides. The node_exporter has achieved version 1.0 with experimental TLS support, and community engagement remains a priority, reflected in discussions around mailing list accessibility and the potential for a tech writer to enhance documentation.
