1.0.0-rc2

OpenTelemetry

• The following extension methods on ResourceBuilder has been moved from the
  OpenTelemetry namespace to the OpenTelemetry.Resources namespace:
  AddEnvironmentVariableDetector, AddAttributes, AddService, and
  AddTelemetrySdk.
  (#1576)
• Metrics API/SDK support is in an experimental state and is not recommended for
  production use. All metric APIs have been marked with the Obsolete
  attribute. See
  #1501
  for more information.
  (#1611)
• Modified SimpleExportProcessor and BatchExportProcessor to abstract classes;
  Added SimpleActivityExportProcessor, SimpleLogRecordExportProcessor,
  BatchActivityExportProcessor, BatchLogRecordExportProcessor; Added the check
  for Activity.Recorded in SimpleActivityExportProcessor and
  BatchActivityExportProcessor
  (#1622)
• Added check in ActivitySourceAdapter class for root activity if traceid is
  overridden by calling SetParentId
  (#1355)
• Resource Attributes now accept int, short, and float as values, converting
  them to supported data types (long for int/short, double for float). For
  invalid attributes we now throw an exception instead of logging an error.
  (#1720)
• Merging "this" resource with an "other" resource now prioritizes the "other"
  resource's attributes in a conflict. We've rectified to follow a recent
  change to the spec. We previously prioritized "this" resource's tags.
  (#1728)
• BatchExportProcessor will now flush any remaining spans left in a Batch
  after the export operation has completed.
  (#1726)
• Fixed a bug to allow the Self Diagnostics log file to be opened simutaneously
  by another process in read-only mode for .NET Framework.
  (#1693)
• Metrics removed as it is not part 1.0.0 release. See issue
  #1501
  for details on Metric release plans.
• Fix Resource attribute telemetry.sdk.version to have correct file version.

OpenTelemetry.Api

• In order to align with the
  spec
  the Status (otel.status_code) tag (added on Activity using the SetStatus
  extension) will now be set as the UNSET, OK, or ERROR string
  representation instead of the 0, 1, or 2 integer representation.
  (#1579 &
  #1620)
• Metrics API/SDK support is in an experimental state and is not recommended for
  production use. All metric APIs have been marked with the Obsolete
  attribute. See
  #1501
  for more information.
  (#1611)
• Status.WithDescription will now ignore the provided description if the
  Status.StatusCode is anything other than ERROR.
  (#1655)
• Metrics removed as it is not part 1.0.0 release. See issue
  #1501
  for details on Metric release plans.
• Relax System.Diagnostics.DiagnosticSource version requirement to allow
  versions >=5.0. Previously only versions up to 6.0 (excluding 6.0) was
  allowed.

OpenTelemetry.Exporter.Console

• AddConsoleExporter extension method for logs moved from
  OpenTelemetry.Trace namespace to OpenTelemetry.Logs namespace.
  (#1576)

• Jaeger will no longer send the otel.status_code tag if the value is UNSET.
  (#1609 &
  #1620)

• Span Event.Name will now be populated as the event field on Jaeger Logs
  instead of message.
  (#1609)

• JaegerExporter batch format has changed to be compliant with the spec. This
  may impact the way spans are displayed in Jaeger UI.
  (#1732)

OpenTelemetry.Exporter.OpenTelemetryProtocol

• Changed OltpTraceExporter class and constructor from internal to public.
  (#1612)

• In OtlpExporterOptions.cs: Exporter options now include a switch for
  Batch vs Simple exporter, and settings for batch exporting properties.

• Introduce a netstandard2.1 build enabling the exporter to use the
  gRPC for .NET library instead of the
  gRPC for C# library
  for .NET Core 3.0+ applications. This required some breaking changes to the
  OtlpExporterOptions.
  (#1662)

OpenTelemetry.Exporter.Zipkin

• Changed ZipkinExporter class and constructor from internal to public.
  (#1612)

• Zipkin will now set the error tag to the Status.Description value or an

• Microsoft.Data.SqlClient v2.0.0 and higher is now properly instrumented
  on .NET Framework.
  (#1599)
• SqlClientInstrumentationOptions API changes: SetStoredProcedureCommandName
  and SetTextCommandContent have been renamed to
  SetDbStatementForStoredProcedure and SetDbStatementForText. They are now
  only available on .NET Core. On .NET Framework they are replaced by a single
  SetDbStatement property.
