• Add new environment variables to the SDK OTEL_PYTHON_EXPORTER_OTLP_{HTTP/GRPC}_{METRICS/TRACES/LOGS}_CREDENTIAL_PROVIDER that can be used to
  inject a requests.Session or grpc.ChannelCredentials object into OTLP exporters created during auto instrumentation #​4689.
• Filter duplicate logs out of some internal logger's logs on the export logs path that might otherwise endlessly log or cause a recursion depth exceeded issue in cases where logging itself results in an exception.
  (#​4695).
• docs: linked the examples with their github source code location and added Prometheus example
  (#​4728)
• Permit to override default HTTP OTLP exporters headers
  (#​4634)

v1.36.0

Compare Source

• Add missing Prometheus exporter documentation
  (#​4485)

• Overwrite logging.config.fileConfig and logging.config.dictConfig to ensure
  the OTLP LogHandler remains attached to the root logger. Fix a bug that
  can cause a deadlock to occur over logging._lock in some cases (#​4636).

• otlp-http-exporter: set default value for param timeout_sec in _export method
  (#​4691)

• Update OTLP gRPC/HTTP exporters: calling shutdown will now interrupt exporters that are sleeping
  before a retry attempt, and cause them to return failure immediately.
  Update BatchSpan/LogRecordProcessors: shutdown will now complete after 30 seconds of trying to finish
  exporting any buffered telemetry, instead of continuing to export until all telemetry was exported.
  (#​4638).
