Release v0.20.0

Added

• Adds semantic conventions for exceptions. (#1492)

• trace.TraceFlags is now a defined type over byte and WithSampled(bool) TraceFlags and IsSampled() bool methods have been added to it. (#1770)
• The Event and Link struct types from the go.opentelemetry.io/otel package now include a DroppedAttributeCount field to record the number of attributes that were not recorded due to configured limits being reached. (#1771)
• The Jaeger exporter now reports dropped attributes for a Span event in the exported log. (#1771)
• Adds test to check BatchSpanProcessor ignores OnEnd and ForceFlush post Shutdown. (#1772)
• Extract resource attributes from the OTEL_RESOURCE_ATTRIBUTES environment variable and merge them with the resource.Default resource as well as resources provided to the TracerProvider and metric Controller. (#1785)

• Added WithProcess* resource configuration options to set Process resource attributes. (#1788)
  • process.pid
  • process.executable.name
  • process.executable.path
  • process.command_args
  • process.owner
  • process.runtime.name
  • process.runtime.version
  • process.runtime.description
• Adds k8s.node.name and k8s.node.uid attribute keys to the semconv package. (#1789)
• Added support for configuring OTLP/HTTP and OTLP/gRPC Endpoints, TLS Certificates, Headers, Compression and Timeout via Environment Variables. (#1758, #1769 and #1811)
  • OTEL_EXPORTER_OTLP_ENDPOINT
  • OTEL_EXPORTER_OTLP_TRACES_ENDPOINT
  • OTEL_EXPORTER_OTLP_METRICS_ENDPOINT
  • OTEL_EXPORTER_OTLP_HEADERS
  • OTEL_EXPORTER_OTLP_TRACES_HEADERS
  • OTEL_EXPORTER_OTLP_METRICS_HEADERS
  • OTEL_EXPORTER_OTLP_COMPRESSION
  • OTEL_EXPORTER_OTLP_TRACES_COMPRESSION

  • OTEL_EXPORTER_OTLP_TRACES_TIMEOUT
  • OTEL_EXPORTER_OTLP_METRICS_TIMEOUT

  • OTEL_EXPORTER_OTLP_METRICS_CERTIFICATE
• Adds otlpgrpc.WithTimeout option for configuring timeout to the otlp/gRPC exporter. (#1821)

Fixed

• The Span.IsRecording implementation from go.opentelemetry.io/otel/sdk/trace always returns false when not being sampled. (#1750)
• The Jaeger exporter now correctly sets tags for the Span status code and message. This means it uses the correct tag keys ("otel.status_code", "otel.status_description") and does not set the status message as a tag unless it is set on the span. (#1761)
• The Jaeger exporter now correctly records Span event's names using the "event" key for a tag. Additionally, this tag is overridden, as specified in the OTel specification, if the event contains an attribute with that key. (#1768)
• Zipkin Exporter: Ensure mapping between OTel and Zipkin span data complies with the specification. (#1688)

Changed

• ⚠️ Breaking Change: go.opentelemetry.io/otel/sdk/metric now applies a default cardinality limit of 2000 to comply with the Metrics SDK specification recommendation. New attribute sets are dropped when the cardinality limit is reached. The measurement of these sets are aggregated into a special attribute set containing attribute.Bool("otel.metric.overflow", true).
