Tempo | v2.10.2

Tempo v2 10 2: consistent exemplar handling and safety caps, frontend MaxExemplars as single source, TraceQL engine cap, default search max result limit 262144

Tempo v2.10.2 released on 12-03-2026


Tempo v2.10.2 is out now. Operators and query authors get consistent exemplar behaviour and tighter safety caps so exemplar selection rules are enforced end-to-end and cannot be used to bypass configured limits.

See the Tempo GitHub release notes or your usual download channels for full details and upgrade instructions.

What’s in this release

  • Apply exemplar hints end-to-end and fix safety cap bypass in metrics queries (PR #6559)
  • Use frontend MaxExemplars configuration as the single source of truth and add a safety cap at TraceQL engine entry points to enforce exemplar limits (PR #6515)
  • Default search max_result_limit increased to 256*1024 (262,144) to allow larger search result sets by default (PR #6525)

Upgrade notes

  • Frontend MaxExemplars is now the single source of truth; review and set your frontend MaxExemplars and be aware the raised default search max_result_limit (256*1024) may increase resource usage — adjust deployments or limits as necessary.
  • If you need to revert, roll back to a prior Tempo version using your usual process.

Let us know how the upgrade performs for you and share any feedback on the Tempo GitHub or in community channels.
