Experimental v0.50.0

0.50.0

💥 Breaking Change

• fix(exporter-*-otlp-grpc)!: lazy load gRPC to improve compatibility with @opentelemetry/instrumenation-grpc #4432 @pichlermarc
  • Fixes a bug where requiring the gRPC exporter before enabling the instrumentation from @opentelemetry/instrumentation-grpc would lead to missing telemetry
  • Breaking changes, removes several functions and properties that were used internally and were not intended for end-users
    • getServiceClientType()
      • this returned a static enum value that would denote the export type (SPAN, METRICS, LOGS)
    • getServiceProtoPath()
      • this returned a static enum value that would correspond to the gRPC service path
    • metadata
      • was used internally to access metadata, but as a side effect allowed end-users to modify metadata on runtime.
    • serviceClient
      • was used internally to keep track of the service client used by the exporter, as a side effect it allowed end-users to modify the gRPC service client that was used
    • compression
      • was used internally to keep track of the compression to use but was unintentionally exposed to the users. It allowed to read and write the value, writing, however, would have no effect.
• feat(api-events)!: removed domain from the Events API #4569 @martinkuba
• fix(api-events)!: renamed EventEmitter to EventLogger in the Events API #4569 @martinkuba

🐛 (Bug Fix)

• fix(exporter--otlp-): use parseHeaders() to ensure header-values are not 'undefined' #4540
  • Fixes a bug where passing undefined as a header value would crash the end-user app after the export timeout elapsed.
• fix(sdk-logs): ensure default resource attributes are used as fallbacks when a resource is passed to LoggerProvider.

Experimental v0.49.0

0.49.0

💥 Breaking Change

• fix(otlp-exporter-base)!: remove unload event from OTLPExporterBrowserBase #4438 @eldavojohn
  • Reason: The 'unload' event prevents sites from taking advantage of Google's backward/forward cache and will be deprecated. It is now up to the consuming site to implement these shutdown events.
  • This breaking change affects users under this scenario:
    1. A user extends the exporter and overrides the shutdown function, and does something which is usually called by the unload listener
    2. We remove the unload event listener
    3. That user's overridden shutdown function no longer gets called

• fix(otlp-transformer): only use BigInt inside hrTimeToNanos() #4484 @pichlermarc
• fix(instrumentation-fetch): do not enable in Node.js; clarify in docs this instr is for web fetch only #4498 @trentm
