3.8.0 / 2025-11-28
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:
- Upgrade to v3.8 and keep the feature flag. Everything should work as before.
- At your own pace, set
scrape_native_histogramstotruein all relevant scrape configs. (There is a global and a per-scrape-config version ofscrape_native_histograms, allowing granular control if needed. It is a good idea to also setscrape_native_histogramsexplicitly tofalsewhere you do not want to scrape Native Histograms. In this way, you do not depend on the default value of the setting anymore.)
