on GitHub

For highlights and announcements pertaining to this release see: Release Notes > 1.21.0.

The following changes are from the previous release 1.21.0-rc.2.

• NuGet: OpenTelemetry v1.21.0

  • OpenTelemetryLoggerOptions is now bound from the Logging:OpenTelemetry
    configuration section using the configuration binding source generator instead
    of reflection, making it fully trim and Native AOT compatible. An empty value
    for a boolean option is now ignored on all target frameworks rather than
    throwing on some, depending on the version of
    Microsoft.Extensions.Configuration.Binder in use.
    (#8100)

  • Fixed the self-diagnostics environment snapshot leaving a dangling comma in a
    redacted OTEL_RESOURCE_ATTRIBUTES value when it contained empty entries.
    (#8104)

  See CHANGELOG for details.

• NuGet: OpenTelemetry.Api v1.21.0

  • Update System.Diagnostics.DiagnosticSource dependency to 11.0.0
    for all target frameworks.
    (#8066)

• NuGet: OpenTelemetry.Exporter.OpenTelemetryProtocol v1.21.0

  • Hardened the experimental disk retry feature.
    • Breaking: When running on .NET on non-Windows platforms, creating the
      exporter now throws an UnauthorizedAccessException if the retry
      directory could be changed by another user. The retry directory must be
      owned by the current user and must not be writable by its group or by
      other users. Each directory and symbolic link in its path must be owned by
      the current user or by root, and those directories must not be writable
      by their group or by other users unless they have the sticky bit set (such
      as /tmp). These checks can be disabled by setting the new
      OTEL_DOTNET_EXPERIMENTAL_OTLP_DISK_RETRY_CHECK_PERMISSIONS setting to
      false.
