Note for users of Native Histograms

This is the first release with Native Histograms as a stable feature. However, scraping Native Histograms has to be activated explicitly via the scrape_native_histograms config setting (newly introduced in this release). To ease the transition, the --enable-feature=native-histograms flag is not a complete no-op in this release, but changes the default value of scrape_native_histograms to true. In the next release (v3.9), the feature flag will be a complete no-op, and the default value of scrape_native_histograms will always be false. If you have been using the feature flag so far, the recommended course of action is the following:

  1. Upgrade to v3.8 and keep the feature flag. Everything should work as before.
  2. At your own pace, set scrape_native_histograms to true in all relevant scrape configs. (There is a global and a per-scrape-config version of scrape_native_histograms, allowing granular control if needed. It is a good idea to also set scrape_native_histograms explicitly to false where you do not want to scrape Native Histograms. In this way, you do not depend on the default value of the setting anymore.)
  3. Remove the feature flag and make sure that everything still works as intended.
  4. Now you are ready for an upgrade to the next release (v3.9).
