v4.0.18 Changelog

New features

Incident deletion

Admins and editors can now permanently delete incidents from the manage dashboard. Deleting an incident removes all associated data including comments, monitor links, and alert associations. A confirmation dialog requires typing delete incident {id} to prevent accidental deletions.

The deletion is also available via the API using DELETE /api/v4/incidents/{incident_id}, which now correctly unlinks associated alerts before removing the incident.

Monitoring data deletion

Added the ability to delete monitoring data with flexible filtering options:

• By monitor: delete data for a specific monitor tag, or all monitors at once
• By date range: specify start and end timestamps to delete data within a window
• From the monitor page: each monitor's Danger Zone card now includes a "Delete Monitoring Data" section with date range inputs and confirmation

This is available both from Manage → Monitoring Data (bulk deletion with filters) and from individual monitor settings pages.

Bug fixes

Timezone handling with UTC

Fixed an issue where selecting UTC as the timezone was not properly recognized. UTC is now explicitly included in the available timezones list, and the timezone store correctly validates and persists the UTC selection. The minute grid component also now respects the selected timezone when grouping data by hour.

Improvements

Missing translations

Added missing translation keys across all supported locales, including uppercase status labels (UP, DOWN, DEGRADED, MAINTENANCE) and the Update Incident string.
