# May 2026 - Alerting

The following updates were released to the Kentik platform for Alerting during May 2026.

## Features
- **Bulk acknowledgment comments**: Added support for bulk ack comments, default sorting of comments by newest first, and a clearer "send" submission icon. 
- **Synthetics notification preview**: Synthetic alarm notifications can now be previewed by ID, letting users test notification templates before deployment. 
- **Cloudflare API Token authentication**: CFMT mitigation platforms now support API Token authentication in addition to API Key, with conditional field requirements and format validation.
- **compactJSON template function**: The `compactJSON` function is now registered in the template editor as an alias for `uglifyJSON` for use in custom notification payloads. 
- **Notification preview with real alarm data**: Notification channel preview and test endpoints can now use real alarm data by passing an `alarmID`.
- **New count metric for policies**: Policies can now use a new "count" metric that counts messages/flows matching policy conditions.
- **Device tags in alert policies**: Policies can now use device tags in dimensions, device selectors, and filters; tags appear in supported-dimension and display-name API responses. 

## Bug Fixes
- **User-friendly alert clear reasons**: Updated alert clearance messages to be more user-friendly and understandable. 
- **Alerting table filter fixes**: Fixed the persistent "Reset to Default" button and restored search terms from the URL on page load. 
- **Policy name length validation**: Flow policy names are now validated to the 50-character API limit to prevent rename errors.
- **Rolling window / toggle mode lock**: Users can no longer switch existing policies between rolling window and toggle mode, ensuring mode consistency.
- **Syslog/SNMP traps policy validators**: Fixed validation errors when creating Syslog/SNMP traps alert policies in the policy drawer. 
- **Device Alerts tab loading**: Reduced device alert lookback from 30 days to 24 hours to prevent the Alerts tab from timing out. 
- **CFMT email validation**: The Account Email field now requires a valid email format when using API Key authentication. 
- **Flowspec rate limit rounding**: Rate-limit values are now rounded to prevent route flaps and mitigation failures.
