    v5.18.2

    Stable baseline release.

    Summary

    This release establishes a stable operational baseline after investigation of a regression in Grafana 13.x affecting Explore Traces / Drilldown.

    Key points

    • Grafana pinned to 12.3.2 for stable operation

    • obswrapper compatibility patches preserved:

      • != selector support
      • service-structure response shaping
    • backend behavior validated (HTTP 200 for affected query families)

    Known limitation

    Grafana 13.x currently exhibits a request lifecycle issue in Explore Traces / Drilldown:

    • context canceled

    • /api/ds/query 400

    • frontend error:

      • TypeError: Cannot read properties of undefined (reading '0')

    This issue is not caused by the backend and has been isolated to Grafana request lifecycle / frontend state handling.

    Reference:

    Operational decision

    • Grafana 13.x retained for regression testing only
    • Grafana 12.3.2 used for stable operation

    Notes

    • No backend behavior changes required beyond compatibility fixes
    • No API or data-shape workarounds introduced
    • This release represents a known-good operational state

    If needed, a minimal reproducible environment and HAR captures are available.
