Prometheus 2.44.0-rc.0 is available

[Bryan Boreham]

Hello Prometheus community!

I am pleased to announce the availability of Prometheus 2.44.0-rc.0.

This release features several performance improvements which should reduce memory and CPU usage. The change to labels which was optional in v2.43 is now built as standard.

A number of improvements to the experimental Native Histograms feature are included.

Promtool can now check the health and readiness of a Prometheus server.

The release also includes several bug-fixes.

You can find the full changelog and download Prometheus 2.44.0-rc.0 at

Container images are also available at

Thank you for your contributions and support in making Prometheus a
better tool for monitoring and alerting.

Regards,

Bryan Boreham
