Prometheus release candidate v2.30.0-rc.0 is available

[Ganesh Vernekar]

Hello everyone,

We just released v2.30.0-rc.0. Some of the highlights of these release are:

• Snapshot in-memory chunks on shutdown for faster restarts. (Note that you will not experience the speedup right when you enable this feature, but during the restarts that happen after Prometheus is already running with this feature enabled).
  
• Configure scrape interval and scrape timeout via relabeling using __scrape_interval__ and __scrape_timeout__ labels respectively.
  
• Ability to fine tune the scrape timestamp tolerance.

Along with this it also includes a bunch of optimisations in remote write, TSDB, promtool, and scraping.

- See the full changelog & grab the binaries: https://github.com/prometheus/prometheus/releases/tag/v2.30.0-rc.0

Please test this release candidate and report any bugs you may encounter.

Thanks,

Ganesh
