I noticed this PR is releasing a stable version of core packages but there isn't any content in RELEASENOTES.md for the version being released.

It is important to update RELEASENOTES.md before creating the release tag because a permalink will become part of the package(s).

Post a comment with "/UpdateReleaseNotes" in the body if you would like me to update release notes.

Note: In the comment everything below "/UpdateReleaseNotes" will be added to RELEASENOTES.md for the version being released. If something is already there it will be replaced.

• Breaking Change: OpenTelemetry.Exporter.OpenTelemetryProtocol now
  defaults to using OTLP/HTTP instead of OTLP/gRPC when targeting .NET Framework
  and .NET Standard. This change may cause telemetry export to fail unless
  appropriate adjustments are made. Explicitly setting OTLP/gRPC may result in a
  NotSupportedException unless further configuration is applied. See
  #6209 for
  full details and mitigation guidance. #6229

/CreateReleaseTag

[opentelemetrybot]

I just pushed the core-1.12.0 tag.

The package workflow should begin momentarily.

[opentelemetrybot]

The packages for core-1.12.0 are now available: https://github.com/open-telemetry/opentelemetry-dotnet/actions/runs/14741025213/artifacts/3033190548.

Once these packages have been validated have a maintainer post a comment with "/PushPackages" in the body if you would like me to push to NuGet.

[rajkumar-rangaraj]

/PushPackages

[opentelemetrybot]

I am uploading the packages for core-1.12.0 to NuGet and then I will publish the release.

[opentelemetrybot]

The release core-1.12.0 has been published and packages should be available on NuGet momentarily.

Have a nice day!
