Release Notes

open-telemetry/opentelemetry-dotnet (OpenTelemetry.Exporter.OpenTelemetryProtocol)

v1.19.1

Release details: 1.19.1

• Fixed NotSupportedException thrown when building a TracerProvider or
  MeterProvider with a large number of wildcard source/meter patterns on
  net8.0, and a related OutOfMemoryException that could occur when many
  such providers were built over the lifetime of a process.

v1.19.0

Release details: 1.19.0

• Added Schema URL to internally created Resource instances.
• Added AlwaysRecordSampler.
• Added an AddOpenTelemetry extension method for IHostApplicationBuilder. It
  registers the OpenTelemetry SDK services and additionally seeds service.name
  from IHostEnvironment.ApplicationName and deployment.environment.name from
  IHostEnvironment.EnvironmentName as low-priority resource defaults. It also
  registers the host's live configuration into DI so that extensions receiving
  only IServiceCollection can contribute configuration sources during setup.
• Extended key/value list attribute handling to cover additional dictionary
  shapes (IEnumerable<KeyValuePair<string, string?>> and IDictionary). These
  attributes will be serialized as JSON objects or kvlist, as appropriate.
• If an exception is thrown when serializing an attribute, the attribute will now
  be dropped.
• Disable HttpClientFactory integration on browser WebAssembly (e.g. Blazor)
  environments to avoid stalled export requests when async HTTP handlers are used.
• Fixed CA certificate loading (e.g. using OTEL_EXPORTER_OTLP_CERTIFICATE) for
  PEM-encoded certificates that only contain a public key.
• Fixed CircularBufferBuckets so the first delta histogram insertion after a
  reset does not result in an unnecessary scale reduction.
• Fixed lazy logger provider builds after a failure from reusing partially
  initialized provider state.
• Fixed parsing of an inbound tracestate header whose member value trimmed to
  an empty value that previously threw an IndexOutOfRangeException internally
  and could silently truncate the tracestate.
• Prevented oversized metric metadata from being cached when it cannot fit within
  the configured request size.
• Reduced allocations when formatting self-diagnostics events with up to three parameters.
• Improved wildcard source/meter name matching to avoid excessive matching time
  at runtime.
• Reduced allocations when creating log record attributes from an array.
• Reduced allocations when setting baggage through the params overload.
• Reduced allocations when constructing SpanAttributes from an array.

v1.18.0

Release details: 1.18.0

• Breaking change: The maximum size of a single OTLP export request is now
  64 MiB by default instead of 128 MiB to conform with the OpenTelemetry specification.
  Raise the value of the new OtlpExporterOptions.MaxRequestSizeBytes property
  to increase the capacity.
• Added OtlpExporterOptions.MaxRequestSizeBytes to configure the maximum OTLP
  request size limit, as required by the OpenTelemetry specification. The default
  is the recommended 64 MiB. A batch whose serialized payload exceeds the limit
  is not sent and is dropped in its entirety. The maximum supported value is
  256 MiB.
• Added OtlpExporterOptions.MaxResponseSizeBytes to configure the maximum size
  of a response the exporter will accept, as required by the OpenTelemetry
  specification. The default is the recommended 4 MiB. A response exceeding the
  limit is discarded and treated as a non-retryable failure.
• Added the otel.sdk.processor.log.processed and otel.sdk.processor.span.processed
  SDK self-observability metrics.
• Added support for serializing attribute values that are key/value lists in
  the OTLP, console and Zipkin exporters.
• The OTLP exporter will now export the logger version, if it was specified.
• Add new ITelemetryHostInitializer interface for applications that do not
  support hosted services, such as Blazor, to use to manually initialize the
  OpenTelemetry SDK as part of application startup.
• BatchActivityExportProcessor and SimpleActivityExportProcessor no longer
  forward spans to the exporter once Shutdown has been called, and
  BatchActivityExportProcessor.Shutdown now waits for in-flight OnEnd calls
  to finish enqueueing before flushing.
• Fixed self-diagnostics log lines being silently dropped when an event message
  was too long to fit in the internal buffer. Such content is now truncated.
• Fixed activity creation throwing when multiple tracer providers returned a
  sampler attribute with the same key.
• Fixed logger, meter and tracer providers leaking background threads if an
  exception is thrown by their constructor after resource creation.
• Avoid formatting exceptions and creating exception attributes when
  RecordException is called on a span that is not recorded.
• Fixed UseOtlpExporter to respect options configured with
  services.Configure<OtlpExporterOptions>(...).
• Clamped the server-supplied OTLP/gRPC retry delay (RetryInfo.retry_delay) to
  a minimum value of 100 milliseconds.
• Fixed serialization failures leaving failed trace, metric, and log batches in
  the serializer's per-thread state.
• Fixed the persistent-storage retry thread terminating permanently on an
  unexpected exception.
• Fixed the OTLP exporter from retrying certain non-transient HTTP failures.
• Improved OTLP log attribute serialization performance by avoiding unnecessary
  boxing.
• Improved OTLP histogram serialization performance by avoiding a redundant
  scan of explicit bucket bounds.
• Fixed persistent storage allowing a blob write to exceed the configured
  maximum storage size.
• Improved OTLP/gRPC response status handling performance by avoiding unnecessary
  header enumeration on .NET 8+.
• Fixed the Zipkin exporter to read responses with HttpCompletionOption.ResponseHeadersRead
  for the .NET Framework and .NET Standard targets.
• Fixed inefficient parsing of the Jaeger uber-trace-id header when targeting
  net462 or netstandard2.0.

v1.17.0

Release details: 1.17.0

• Added support for a Schema URL on Resource instances.
• The Resource Schema URL is now printed alongside the resource attributes
  when using the Console and OTLP exporters.
• Added ExcludedTagKeys property to MetricStreamConfiguration to support
  excluding specific tag keys from metric streams.
• Updated tracestate key validation to comply with the W3C Trace Context
  Level 2 grammar.
• The SDK now depends on Microsoft.Extensions.Configuration.EnvironmentVariables
  instead of using a vendored implementation.
• All libraries are now marked as trim and AOT compatible.
• Fixed a metric storage leak that occurred when meters and instruments were
  repeatedly created and disposed.
• Fixed TraceContextPropagator to normalize empty tracestate header values
  to null when extracting trace context.
• Fixed OtlpLogExporter so OtlpExporterOptions.ExportProcessorType and
  OtlpExporterOptions.BatchExportProcessorOptions are respected when
  LogRecordExportProcessorOptions are not configured.
• Fixed the OTLP exporter dropping retryable data instead of saving it to disk
  when persistent storage retry is enabled and an export exceeds the configured
  timeout.
• Fixed the OTLP/HTTP exporter silently dropping data when an export timed out.
• Fixed the OTLP/gRPC exporter logging incorrectly when an export timed out.
• Performance and memory improvements for the OTLP exporter when exporting logs
  and metrics.

v1.16.0

Release details: 1.16.0

• Breaking Change Explicit histogram boundaries no longer allow more than
  10 million values.
• Fix BaggagePropagator to correctly follow Key and Value Encoding rules.
• Add support for the W3C randomness flag.
• Fixed TraceContextPropagator to deduplicate duplicate tracestate keys.
• ObservedTimestamp will now be exported for logs in the console exporter.
• Fixed NullReferenceException when exporting OTLP logs if the scope key is
  null.
• Added opt-in support for gzip compression to the OTLP exporter.
• Fixed OTLP disk retry data being stored incorrectly when using persistent
  storage retry.
• Fixed OtlpLogExporter integration with IHttpClientFactory.
• Do not enable the OTLP integration with IHttpClientFactory when mTLS is
  enabled.
• Handle Retry-After response headers that specify a date instead of a delay.
• observed_time_unix_nano will no longer always be identical to time_unix_nano
  when using the logs bridge API.
• Stop validating View-provided metric stream Name against the instrument name
  syntax.
• Fix incorrect validation of OTEL_BSP_* and OTEL_BLRP_* environment variables.
• Fix observable instrument callbacks running once per reader instead of once per
  collection cycle.
• Added exception safety for user-supplied ExemplarReservoir implementations.
• Fixed a circular reference which could cause a LoggerProvider to fail to
  resolve when one of its dependencies depends on ILogger or ILoggerFactory.
