Prometheus Support Policy
Prometheus LTS releases get approximately 6 months of bug fixes, significantly longer than the standard ~6-week window for regular releases. Non-LTS releases are superseded by the next release and receive no backported fixes.
What You Need to Know
Prometheus 3.x is the current generation. Prometheus 2.x is end-of-life.
Prometheus 3.10 is the latest release with the newest features and bug fixes.
Native histograms in Prometheus 3.x dramatically reduce the cardinality cost of histogram metrics.
For large-scale deployments, consider Thanos, Mimir, or VictoriaMetrics for long-term storage and HA.
