# v2.1.43

> Helm v2.1.43 changelog - 2026-09-17

<Update label="Bifrost Helm" description="v2.1.43">
  ## Changelog

  * Added `bifrost.plugins.telemetry.config.user_labels_enabled` (default `false`) — adds `user_id` and `user_name` labels to every `bifrost_*` metric. Off by default because these are unbounded: they multiply metric series by end-user count, on top of a `virtual_key_id` label that already reaches tens of thousands of values in large deployments, and Prometheus cannot drop a label after the fact. Datadog and Splunk emit these dimensions unconditionally, since a costly tag can be dropped server-side there.
