Changelog

0.7.0-beta.4

Bug fixes

Use 1.7.1 of ASP.NET Core instrumentation.
- Fixed issue #4466 where the activity instance returned by Activity.Current was different than instance obtained from IHttpActivityFeature.Activity. (#5136)
- Fixed an issue where the http.route attribute was not set on either the Activity or http.server.request.duration metric generated from a request when an exception handling middleware is invoked. One caveat is that this fix does not address the problem for the http.server.request.duration metric when running ASP.NET Core 8. ASP.NET Core 8 contains an equivalent fix which should ship in version 8.0.2 (see: dotnet/aspnetcore#52652). (#5135)
- Fixes scenario when the net6.0 target of this library is loaded into a .NET 7+ process and the instrumentation does not behave as expected. This is an unusual scenario that does not affect users consuming this package normally. This fix is primarily to support the opentelemetry-dotnet-instrumentation project. (#5252)
Use 1.7.1 of HTTP instrumentation.
- .NET Framework - fix description for http.client.request.duration metric. (#5234)

New features

#81 Adds a .NET 8 test project and integrates it into the OATS test matrix.
#85 Adds resource detectors for Azure, host, process, process runtime, and container resource attributes.
#87 Add a new OtlpExporter class supporting specifying OTLP protocol, endpoint, and header
Use 1.7.1 of Runtime instrumentation.
- Update OpenTelemetry.Api to 1.7.0. (#1486)

Deprecation

#87 Deprecate use of GRAFANA_CLOUD_* environment variables in code and documentation

The use of CloudOtlpExporter and GRAFANA_CLOUD_* environment variables is deprecated. Instead use OtlpExporter for code-level configuration, and OTEL_EXPORTER_OTLP_PROTOCOL, OTEL_EXPORTER_OTLP_ENDPOINT, and OTEL_EXPORTER_OTLP_HEADERS for configuration via environment variables.

0.7.0-beta.3

Bug fixes

Sets OTEL_DOTNET_EXPERIMENTAL_ASPNETCORE_ENABLE_GRPC_INSTRUMENTATION to true when enabling tracing. gRPC instrumentation is experimental, while HTTP is stable.

0.7.0-beta.2

Bug fixes

#71: Lazy-loading of ASP.NET Core instrumentation was broken. This was fixed by updateing changed class names of ASP.NET Core instrumentation library extension classes.

0.7.0-beta.1

BREAKING CHANGES

Use 1.7.0 of ASP.NET Core instrumentation.
- Removes support for OTEL_SEMCONV_STABILITY_OPT_IN. Instrumentation will only emit stable conventions.
- Defaults OTEL_DOTNET_EXPERIMENTAL_ASPNETCORE_ENABLE_GRPC_INSTRUMENTATION to true. gRPC instrumentation is experimental, while HTTP is stable.
Use 1.7.0 of HTTP instrumentation.
- http.user_agent Activity tag removed from HTTP instrumentation.

0.6.0-beta.3

Bug fixes

#65: Using the distribution broke self-contained applications. This has been fixed by using a different way to determine the distribution version.
#64: The version in telemetry.distro.version contained a trailing commit hash. This commit hash is removed now before populating the attribute.

0.6.0-beta.2

New features

Use 1.6.0-beta.3 of upstream instrumentation libraries.
Allow specifying custom resource attributes via GrafanaOpenTelemetrySettings.
Run unit tests on .NET 8.
Use libraries released with .NET 8.
Improve accuracy of resource attributes telemetry.distro.name and telemetry.distro.version.

Bug fixes

Make unit tests runnable for non-net462 targets.
