Bug fixes and enhancements

edit

edit

Known issues

edit
  • After upgrading Elastic prebuilt rules, some rules are erroneously duplicated as custom rules. To remove them, go to the Rules page (Manage → Rules), click the Custom rules filter next to the search bar, then select and delete the duplicate rules.
  • When using the Osquery Manager integration with Elastic Agent, Osquery results aren’t properly written to Elasticsearch and, therefore, cannot be viewed in Kibana (#34250). We recommend that Osquery users skip Elastic Stack version 8.6.0 and upgrade to Elastic Stack version 8.6.1 or later when available.
  • Investigation guides for some prebuilt rules may not render correctly if they include an escaped character (such as \"). To resolve this, update your prebuilt rules once you receive a rule update prompt on the Rules page (#2447).
