Kibana 8.4.0edit

Review the following information about the Kibana 8.4.0 release.

Known issuesedit

If you have alerting rules that have been snoozed, do not upgrade Kibana to 8.4.0. Upgrade to 8.4.1 instead.

To determine if you have snoozed alerting rules, open the main menu, then click Stack Management → Rules and Connectors. Filter the rule list by selecting View → Snoozed. If you must upgrade to 8.4.0, for each space, cancel the snooze for all affected rules before you upgrade.

To identify snoozed rules in all Spaces using Dev Tools, run the following query:

GET /.kibana/_search
{
  "query": {
    "exists": {
      "field": "alert.isSnoozedUntil"
    }
  }
}

If you upgraded Kibana to 8.4.0 and you have alerting rules configured to snooze notifications, you will receive the following error message:

FATAL  Error: Unable to complete saved object migrations for the [.kibana] index.

To fix that problem, restore your previous version, then upgrade to 8.4.1 instead.

Breaking changesedit

Breaking changes can prevent your application from optimal operation and performance. Before you upgrade to 8.4.0, review the breaking changes, then mitigate the impact to your application.

Deprecationsedit

The following functionality is deprecated in 8.4.0, and will be removed in 9.0.0. Deprecated functionality does not have an immediate impact on your application, but we strongly recommend you make the necessary updates after you upgrade to 8.4.0.

Deprecates ApiKey authentication for interactive users

Details
The ability to authenticate interactive users with ApiKey via a web browser has been deprecated, and will be removed in a future version.
