  • Breaking Change: .NET Framework and .NET Standard builds now default to
    exporting over OTLP/HTTP instead of OTLP/gRPC. This change could result in a
    failure to export telemetry unless appropriate measures are taken.
    Additionally, if you explicitly configure the exporter to use OTLP/gRPC it may
    result in a NotSupportedException without further configuration. Please
    carefully review issue
    (#6209)
    for additional information and workarounds.

  • Removed the following package references:

    • Google.Protobuf
    • Grpc
    • Grpc.Net.Client

    These changes were made to streamline dependencies and reduce the footprint of
    the exporter.
    (#6005)

  • Switched from using the Google.Protobuf library for serialization to a
    custom manual implementation of protobuf serialization.
    (#6005)

    without modifications.

    semantic conventions that are not part of the stable specification. This
    change ensures that the exporter no longer modifies or assumes the value of
    peer service attributes, aligning it more closely with OpenTelemetry protocol
    specifications.

core-1.10.0

For highlights and announcements pertaining to this release see: Release Notes > 1.10.0.

The following changes are from the previous release 1.10.0-rc.1.

• NuGet: OpenTelemetry v1.10.0

  • Promoted the MetricPoint reclaim feature for Delta aggregation temporality
    from experimental to stable.
    (#5956)

    Previous Behavior:
    The SDK maintained a fixed set of MetricPoints which were assigned on a
    first-come basis based on the tags. MetricPoint reclaim was an experimental
    feature users could opt-into setting the environment variable
    OTEL_DOTNET_EXPERIMENTAL_METRICS_RECLAIM_UNUSED_METRIC_POINTS=true.

    New Behavior:
    MetricPoint reclaim is now enabled by default when Delta aggregation
    temporality is used without the need to set an environment variable. Unused
    MetricPoints will automatically be reclaimed and reused for future
    measurements. There is NO ability to revert to the old behavior.
