  • Updates Elastic prebuilt machine learning detection rules for some Windows and Linux anomalies with new v3 machine learning jobs. A confirmation modal is displayed when updating rules if v1/v2 jobs are installed. If you’re using 8.2 or earlier versions of Beats or Elastic Agent, you may need to duplicate prebuilt rules or create new custom rules before you update the prebuilt rules. Once you update the prebuilt rules, they will only use v3 machine learning jobs. Refer to Troubleshoot missing alerts for machine learning jobs for more information (#128334).
