These methods make it easier for users to programmatically obtain and exchange authentication tokens when interacting with Azure Container Registry. (#51701)

Conversations Authoring 1.0.0-beta.3 Changelog

Breaking Changes

  • Changed parameter type from ConversationAuthoringDeleteDeploymentDetails to ConversationAuthoringProjectResourceIds when calling DeleteDeploymentFromResources, with property name changed from AssignedResourceIds to AzureResourceIds.

  • Changed function name from GetDeploymentResources to GetProjectResources, change its return type from ConversationAuthoringAssignedDeploymentResource to ConversationAuthoringAssignedProjectResource.

  • Changed function name from AssignDeploymentResources to AssignProjectResources, and its parameter type from ConversationAuthoringAssignDeploymentResourcesDetails to ConversationAuthoringAssignProjectResourcesDetails.

  • Changed function name from UnassignDeploymentResources to UnassignProjectResources, changed its parameter type from ConversationAuthoringUnassignDeploymentResourcesDetails to ConversationAuthoringProjectResourceIds.

  • Changed function name from GetAssignDeploymentResourcesStatus to GetAssignProjectResourcesStatus, change its return type from ConversationAuthoringDeploymentResourcesState to ConversationAuthoringProjectResourcesState.

Features Added

  • Added support for service version 2025-11-15-preview.

  • Added support for service version 2025-11-01.

OpenTelemetry Exporter 1.6.0-beta.2 Changelog

Breaking Changes

  • Default Sampler Changed (#54942): The default sampling behavior has been changed from ApplicationInsightsSampler with 100% sampling (all traces sampled) to RateLimitedSampler with 5.0 traces per second. This change significantly reduces telemetry volume for high-traffic applications and provides better cost optimization out of the box. Impact: Applications with more than 5 requests per second will see fewer traces exported by default. Migration: To maintain the previous behavior (100% sampling), explicitly configure the sampler: 
    // Option 1: Set SamplingRatio and clear TracesPerSecond
builder.Services.AddOpenTelemetry()
.UseAzureMonitorExporter(options =>
{
options.SamplingRatio = 1.0f;
options.TracesPerSecond = null;
});
// Option 2: Use environment variables
// OTEL_TRACES_SAMPLER=microsoft.fixed_percentage
// OTEL_TRACES_SAMPLER_ARG=1.0

Bugs Fixed

  • Fixed performance counter metrics not using configured resource attributes (cloud_RoleName and cloud_RoleInstance), which previously showed “unknown_service:appName” instead of the configured values. (#54944)
