Kibana 8.3.3

Review the following information about the Kibana 8.3.3 release.

If you have alerting rules that have been snoozed, do not upgrade Kibana from 8.3.3 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 from 8.3.3 to 8.4.0 and you had 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.
