Release Notes

open-telemetry/opentelemetry-dotnet (OpenTelemetry.Api)

v1.14.0

Release details: 1.14.0

• Add support for .NET 10.0.
• Breaking Change When targeting net8.0, the package now depends on version
  8.0.0 of the Microsoft.Extensions.DependencyInjection.Abstractions,
  Microsoft.Extensions.Diagnostics.Abstractions,
  Microsoft.Extensions.Hosting.Abstractions and
  Microsoft.Extensions.Logging.Configuration NuGet packages.
• Update System.Diagnostics.DiagnosticSource dependency to 10.0.0
  for all target frameworks.
• Update Microsoft.Extensions.* dependencies to 10.0.0
  for .NET Framework and .NET Standard.
• Breaking Change NuGet packages now use the Sigstore bundle format
  (.sigstore.json) for digital signatures instead of separate signature
  (.sig) and certificate (.pem) files. This requires cosign 3.0 or later
  for verification. See the Digital signing
  section for updated verification instructions.

v1.13.1

Release details: 1.13.1

• In version 1.13.0, the digital signature (.dll-keyless.sig) and
  certificate (.dll-keyless.pem) files were unintentionally omitted from the
  published NuGet packages.
• This hotfix restores the Sigstore signing artifacts for all target frameworks
  (net462, netstandard2.0, netstandard2.1, net8.0, net9.0), ensuring
  the integrity of DLL verification using Sigstore cosign.

v1.13.0

Release details: 1.13.0

• gRPC calls to export traces, logs, and metrics using OtlpExportProtocol.Grpc
  now set the TE=trailers HTTP request header to improve interoperability.
• EventName is now exported by default as EventName instead of
  logrecord.event.name when specified through ILogger or the experimental
  log bridge API.
