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_histogram 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_histogram to true. In the next release (v3.9), the feature flag will be a complete no-op, and the default value of scrape_native_histogram 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_histogram to true in all relevant scrape configs. (There is a global and a per-scrape-config version of scrape_native_histogram, allowing granular control if needed. It is a good idea to also set scrape_native_histogram 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).

v1.28.1 🐩

This release features two fixes: one to ensure that we correctly upload the Linux-amd64 binaries for the Community and Enterprise editions, and one contributed by an external developer to ensure that we still return documents that don't contain the sortable attribute after those that do.

9.2.2

QuestDB 9.2.2 is another stability release, primarily fixing some query snags. With this, we've packaged a performance improvement for vertically-scaled machines, and some new SQL functions.

For any questions or feedback, please join us on Slack or on Discourse.

See also our prettier release notes page.

Breaking changes 💥

  • We've removed the legacy txn scoreboard (v1).
    • Using the new scoreboard (v2) has been the default for some time now.
    • If you have been manually overriding this config option (cairo.txn.scoreboard.format=1), it will no longer take effect, but the instance will boot and function as normal.
  • MANUAL PERIOD views will now only be refreshed by manual trigger, and not also automatically when the time period ends.
    • This was always the intended behaviour; it is unexpected that a MANUAL view should refresh automatically.

SQL

New weighted statistics functions

  • weighted_avg(DD) - computes the weighted average based on a 'value' column and a 'weights' column.
    • A straightforward weighted average calculation.
  • weighted_stddev_rel(DD) - computes the weighted standard deviation based a 'value' column and a 'reliability weights' column.
    • Reliability weights are based on how trusted or reliable the particular value should be treated.
  • weighted_stddev_freq(DD) - computes the weighted standard deviation based on a 'value' column and a 'frequency weights' column.
    • Frequency weights are based on the frequency of a particular sample occurring in the dataset.

v1.28.0 🐩

This release introduces improvements to language support and separates the community and enterprise binary editions. We now offer binaries under the BUSL-1.1 license, identified by the "enterprise" term in their names, in addition to our MIT-licensed binaries, which retain their original names. Docker images for the enterprise edition are available in the getmeili/meilisearch-enterprise repository.

📝 Licensing

  • Separation of EE and CE. CE remains the default binary, and the name does not change by Louis on #6011

✨ Enhancement

  • Charabia v0.9.9: introduce a better word segmentation for Thai, Khmer, and German languages by @ManyTheFish in #6007
  • Expose batch progress traces on the metrics route to improve the indexing debugging experience by @Kerollmops in #5956

🔩 Miscellaneous

  • Remove version from the name of the test job in CI by @paulden in #6012
  • Upgrade most of the dependencies by @Kerollmops in #6002
  • Build x86 and ARM images on GitHub-hosted runners by @paulden in #6003
  • Fix SDKs tests to use the enterprise edition and continue testing the sharding feature by @curquiza in #6013

🫂 New Contributors

  • @paulden made their first contribution in #6003
