Summary
Prometheus 2.0 is a major upcoming release focused on overhauling the storage layer to address performance bottlenecks caused by increasingly dynamic environments like Kubernetes. An early alpha version is now available for testing, featuring a new storage concept designed for improved performance and future features like hot backups – however, it's incompatible with existing data and is expected to be unstable. The developers are seeking community feedback to stabilize the release and will provide upgrade documentation closer to the final version.
