Sourced from OpenTelemetry.Instrumentation.Http's releases.

1.7.0 of AspNetCore and Http instrumentation libraries

From a feature standpoint, 1.7.0 release of these two instrumentation libraries don't have any additional changes on top of the respective 1.6.0 version packages. The major difference in 1.7.0 is that it depends on 1.7.0 version of OpenTelemetry.Api.ProviderBuilderExtensions which brings in >=8.0.0 version of System.Diagnostics.DiagnosticSource.

If you're interested in knowing all of the changes that went into 1.6.0 release, please go through the Release notes of all the previous pre-release versions for 1.6.0 for these two packages.

1.6.0 of AspNetCore and Http instrumentation libraries

This is the first stable release of both AspNetCore and Http instrumentation libraries. If you're interested in knowing all of the changes that went into 1.6.0 release, please go through the Release notes of all the previous pre-release versions for 1.6.0 for these two packages.

OpenTelemetry.Instrumentation.AspNetCore

• Re-introduced support for gRPC instrumentation as an opt-in experimental feature. From now onwards, gRPC can be enabled by setting OTEL_DOTNET_EXPERIMENTAL_ASPNETCORE_ENABLE_GRPC_INSTRUMENTATION flag to True. OTEL_DOTNET_EXPERIMENTAL_ASPNETCORE_ENABLE_GRPC_INSTRUMENTATION can be set as an environment variable or via IConfiguration. The change is introduced in order to support stable release of http instrumentation. Semantic conventions for RPC is still experimental and hence the package will only support it as an opt-in experimental feature. Note that the support was removed in 1.6.0-rc.1 version of the package and versions released before 1.6.0-rc.1 had gRPC instrumentation enabled by default. (#5130)
