Release announcements, helpful tips, and community discussion


Cerb (10.4.15) is a maintenance update released on May 29, 2024. It includes 11 minor features and fixes from community feedback covering the 10.4 update. You can follow these instructions to upgrade.



  • [Records/Ticket] On ticket records, added a new mask.merged: search filter for matching tickets based on source masks merged into them. This can be a single mask or an array. Thanks to ChargeOver for the feature request.


  • [Metrics/Data Queries] In metrics.timeseries data queries, added new function: aggregations for faceted_average, faceted_min, faceted_max for gauges. These functions aggregate contemporary samples with different dimensions that aren’t specified in by:. For instance, the metric has dimensions for group/bucket, and function:faceted_average will return the average number of total open tickets as the sum of the bucket averages, while function:average returns a simple average across buckets. The avg, min, and max functions now act directly against samples. For instance, a gauge metric that samples the current temperature in various locations would never aggregate those locations into a total temperature; it would use a simple average across all samples for a regional/global average temperature at given times.

  • [Automations/Usability] In automations, when using the record.upsert: command, a policy was non-intuitively required for record.upsert:, record.create:, and record.update:. The record.create: and record.update: policies during an upsert are now optional and will otherwise use the same policy as record.upsert: (e.g. record type).

  • [Automations/Editor/Usability] Improved error reporting in the automation editor. Command errors now include the key path in the script where the error was triggered.

  • [UI/Ajax/UX] When an asynchronous (Ajax) request to the server receives an HTTP 504 (Gateway Timeout) response, a more helpful error code is displayed in the browser. Previously these requests could silently fail.


  • [Metrics/Data Queries] Fixed an issue with faceted gauge metrics like when using a period: of week, week-sun, month, or year. These are expected to aggregate (avg/min/max) the daily totals within the period, but returned a sum of the daily aggregations instead. Thanks to @mryanb for the bug report.

  • [Data Queries/Subtotals] Fixed an issue in worklist.subtotals data queries when using by.count: on a worker-based custom field. Using field or both returned the ID, when the former should have returned the name. Thanks to @mryanb for the bug report.

  • [Automations] Fixed an issue with record.upsert: in automations. Previously, query errors like unknown filters were ignored (e.g. iid: vs id:), which resulted in record.create: always triggering when record.update: was expected. Invalid queries now properly return an error.

  • [Automations] Fixed an issue with in automations. Previously, query errors like unknown filters were ignored and zero results were returned. Invalid queries now properly return an error.

  • [Records/Groups] Fixed an issue where group-owned signatures were orphaned when a group was deleted. [#1787]


  • [Security/Dependencies] Updated the Smarty template library from v4.3.4 to v4.5.3 in response to a security advisory.
