You can now preview target hosts on the downtime configuration screen

MackerelImproved

You can now verify downtime target hosts in advance and refine log searches, while dashboard auto-refresh conditions changed.

Changes

  • You can preview the list of hosts matching service and role filter conditions before saving on downtime creation and edit screens
  • In structured log searches, enclosing key names in double quotes distinguishes keys containing dots from nested keys
  • Auto-refresh is paused when the custom dashboard or a graph widget display period is 30 days or longer
  • The disclosed PHP vulnerabilities (CVE-2026-109618, CVE-2026-109619) do not affect Mackerel service infrastructure or official agents
