Updated OpenTelemetry.Exporter.OpenTelemetryProtocol from 1.12.0 to 1.15.3.

Release notes

Sourced from OpenTelemetry.Exporter.OpenTelemetryProtocol's releases.

1.15.3

For highlights and announcements pertaining to this release see: Release Notes > 1.15.3.

The following changes are from the previous release 1.15.2.

  • NuGet: OpenTelemetry v1.15.3

    • Fix resource leak in batch and periodic exporting task workers for Blazor/WASM.
      (#​7069)

    • Fixed LogRecord.LogLevel to preserve LogLevel.None and handle
      unspecified or out-of-range severities without returning invalid enum values.
      (#​7092)

    • Fixed OTEL_TRACES_SAMPLER_ARG handling to treat out-of-range, NaN, and
      infinite values as invalid and fall back to the default ratio when using
      traceidratio and parentbased_traceidratio samplers.
      (#​7103)

    See CHANGELOG for details.

  • NuGet: OpenTelemetry.Api v1.15.3

    • Fix baggage and trace headers not respecting the maximum length in some cases.
      (#​7061)

    • Improve efficiency of parsing of baggage and B3 propagation headers.
      (#​7061)

    • Breaking change: Fixed tracestate parsing to reject keys that do not
      begin with a lowercase letter, including keys beginning with digits, to
      align with the W3C Trace Context specification.
      (#​7065)

    • Fixed BaggagePropagator to trim optional whitespace (OWS) around =
      separators when parsing the baggage header, as required by the
      W3C Baggage specification.
      (#​7009)

    • Fixed BaggagePropagator to strip baggage properties (e.g. ;metadata)
      from values when parsing the baggage header.
      (#​7009)

    See CHANGELOG for details.

  • NuGet: OpenTelemetry.Api.ProviderBuilderExtensions v1.15.3

For highlights and announcements pertaining to this release see: Release Notes > 1.15.0.

The following changes are from the previous release 1.14.0.

  • NuGet: OpenTelemetry v1.15.0

    • Added support for the OTEL_SDK_DISABLED environment variable in TracerProvider,
      MeterProvider, and LoggerProvider. When OTEL_SDK_DISABLED=true,

      startup, later changes have no effect.
      (#​6568)

      (#​6648)

      (#​6737)

    See CHANGELOG for details.

  • NuGet: OpenTelemetry.Api v1.15.0

    • Added a new overload for TracerProvider.GetTracer which accepts an optional
      string? schemaUrl parameter, allowing a schema URL to be set on the Tracer.
      (#​6736)

    See CHANGELOG for details.

  • NuGet: OpenTelemetry.Api.ProviderBuilderExtensions v1.15.0

    No notable changes.

The following changes are from the previous release 1.13.0-beta.1.

1.13.0

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.

      {
    "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)
