open-telemetry/opentelemetry-dotnet core-1.13.0 on GitHub

For highlights and announcements pertaining to this release see: Release Notes > 1.13.0.

The following changes are from the previous release 1.12.0.

NuGet: OpenTelemetry v1.13.0
- Added a verification to ensure that a MetricReader can only be registered
  to a single MeterProvider, as required by the OpenTelemetry specification.
  (#6458)
- Added FormatMessage configuration option to self-diagnostics feature. When
  set to true (default is false), log messages will be formatted by replacing
  placeholders with actual parameter values for improved readability.
  Example OTEL_DIAGNOSTICS.json:
```
{
    "LogDirectory": ".",
    "FileSize": 32768,
    "LogLevel": "Warning",
    "FormatMessage": true
}
```
- Fixed parsing of OTEL_TRACES_SAMPLER_ARG decimal values to always use .
  as the delimiter when using the traceidratio sampler, preventing
  locale-specific parsing issues.
  (#6444)
See CHANGELOG for details.
NuGet: OpenTelemetry.Api v1.13.0
- Added AddLink(SpanContext, SpanAttributes?) to TelemetrySpan to support
  linking spans and associating optional attributes for advanced trace relationships.
  (#6305)
- Experimental (only in pre-release versions): Added the EventName property
  to LogRecordData
  (#6306)
See CHANGELOG for details.
NuGet: OpenTelemetry.Api.ProviderBuilderExtensions v1.13.0
No notable changes.
See CHANGELOG for details.
NuGet: OpenTelemetry.Exporter.Console v1.13.0
No notable changes.
See CHANGELOG for details.
NuGet: OpenTelemetry.Exporter.InMemory v1.13.0
No notable changes.
See CHANGELOG for details.
NuGet: OpenTelemetry.Exporter.OpenTelemetryProtocol v1.13.0
- Fixed an issue in .NET Framework where OTLP export of traces, logs, and
  metrics using OtlpExportProtocol.Grpc did not correctly set the initial
  write position, resulting in gRPC protocol errors.
  (#6280)
- If EventName is specified either through ILogger or the experimental
  log bridge API, it is exported as EventName by default instead of
  logrecord.event.name which was previously behind the
  OTEL_DOTNET_EXPERIMENTAL_OTLP_EMIT_EVENT_LOG_ATTRIBUTES feature flag.
  Note that exporting logrecord.event.id is still behind that same feature
  flag. (#6306)
- gRPC calls to export traces, logs, and metrics using OtlpExportProtocol.Grpc
  now set the TE=trailers HTTP request header to improve interoperability.
  (#6449)
- Improved performance exporting byte[] attributes as native binary format
  instead of arrays.
  (#6534)
See CHANGELOG for details.
NuGet: OpenTelemetry.Exporter.Zipkin v1.13.0
- Removed the peer service resolver, which was based on earlier experimental
  semantic conventions that are not part of the stable specification. This
  change ensures that the exporter no longer modifies or assumes the value of
  peer service attributes.
  (#6191)
- Extended remote endpoint calculation to align with the opentelemetry-specification.
  (#6191)
See CHANGELOG for details.
