Tempo query frontend fails to fetch trace JSON::

To work around this problem, use the distributed tracing UI plugin to view traces.

Probabilistic Sampling Processor (Technology Preview):: This release introduces the Probabilistic Sampling Processor as a Technology Preview feature for the {OTELShortName} Collector. The Probabilistic Sampling Processor samples a specified percentage of trace spans or log records statelessly and per request. You can use the Probabilistic Sampling Processor if you handle high volumes of telemetry data and seek to reduce costs by reducing processed data volumes.
