Long-term support | Prometheus

Prometheus LTS are selected releases of Prometheus that receive selected bug fixes for an extended period of one year.
Every 6 weeks, a new Prometheus minor release cycle begins. After those 6 weeks, minor releases generally no longer receive bug fixes. If a user is impacted by a bug in a minor release, they often need to upgrade to the latest Prometheus release.
Upgrading Prometheus should be straightforward thanks to our API stability guarantees. However, there is a risk that new features and enhancements could also bring regressions, requiring another upgrade.
Prometheus LTS version will only receive fixes for selected issues with high severity, i.e. a CVSS rating of 7.0 or higher. Additional changes for bug fixes or documentation fixes might be added. The build toolchain will also be kept up-to-date. This is a best effort commitment by the community, contributions are welcome. Support periods of two subsequent LTS version should overlap by at least one month. This allows users that rely on Prometheus to limit the upgrade risks while still having a Prometheus server maintained by the community.
