0.217.0

🚀 Features

• feat(otlp-transformer): replace protobufjs trace serialization with custom implementation #6625 @pichlermarc
• feat(configuration): auto-generate TypeScript types from OTel declarative config JSON schema (stable v1.0.0) using json-schema-to-typescript and ajv #6533 @MikeGoldsmith
• feat(configuration, sdk-node): startNodeSDK() code path now uses log_level configuration to setup a DiagConsoleLogger #6668 @trentm
  • Note that allowed values for log_level in a configuration YAML file are not the same set as for OTEL_LOG_LEVEL. Use log_level: trace to see all logs (equivalent of OTEL_LOG_LEVEL=ALL). Use log_level: fatal to effectively disable the SDK's internal diagnostic logger (equivalent of OTEL_LOG_LEVEL=NONE).
  • If log_level is not specified, a diagnostic console logger at "info" level will be setup.
  • An invalid YAML config file will now result in a noop OTel SDK.
