Tempo v2.10.2 released on 12-03-2026
Tempo v2.10.2 is out now. It restores correct exemplar behaviour end-to-end, closes a safety-cap bypass in metrics queries and centralises exemplar limits on the frontend while raising the default search max_result_limit to 256*1024.
Find the full notes and linked pull requests on the Tempo GitHub repository for implementation details and configuration options.
What’s in this release
- Bugfix: apply exemplar hint end-to-end (ingestion through queries and visualisation) and fix safety cap bypass in metrics queries (PR #6559)
- Enhancement: use frontend MaxExemplars config as the single source of truth for exemplar limits and add a safety cap at TraceQL engine entry points (PR #6515)
- Change: default search max_result_limit increased to 256*1024 (262,144), which may have resource implications for some deployments (PR #6525)
Upgrade notes
- Default search max_result_limit is now 256*1024 — operators who need a different limit should override the default in their configuration (see PR #6525 for details)
- If the adjusted exemplar limits or the higher search result default cause issues, revert to a previous Tempo version or adjust the frontend MaxExemplars and engine safety caps as appropriate
