FastAPI 0.143.0 makes automatic telemetry configuration opt-in
Published by FastAPI releases
Our editorial summary
FastAPI 0.143.0 requires an explicit choice to let the framework configure OpenTelemetry exporters from environment settings. Applications that already configure their own providers and exporters are unaffected by this change.
Our editorial notes
Why it matters: If your API relies on automatic telemetry setup, an upgrade could change whether traces reach your exporter.
Takeaway: Check how your application configures telemetry, then verify exported traces during an upgrade test.
