Version 2.2 release notes

Grafana Enterprise Traces (GET) 2.2 builds off Tempo 2.2, so it inherits all the features, enhancements, and bug fixes of the upstream project. As a result, we recommend that you read the Tempo 2.2 release notes for a description of the most notable changes.

Note: Tempo 2.2 has implemented a GPRC streaming endpoint for TraceQL queries. This capability isn’t yet supported in GET.

GET is fully Tempo-compatible. You can use a GET 2.2 binary in a Tempo 2.2 deployment with minimal changes.

Features and enhancements

GET can perform cross-tenant and cross-cluster queries using the optional federation-frontend service. This release makes the following changes to this service:

Expose per-target TLS settings
Add /api/echo endpoint. This fixes an error message that the user would have seen when configuring Grafana to query GET.
