Release highlights

AI Projects 2.0.0-beta.5 Changelog

Features Added

  • Add project.beta route for accessing beta features, including:
  • project.beta.schedules
  • project.beta.redTeams
  • project.beta.memoryStores
  • project.beta.insights
  • project.beta.evaluators
  • project.beta.evaluationTaxonomies

AI Projects 2.0.0 Changelog

Breaking changes

  • change RedTeam property target from required to optional.
  • remove container_app from AgentKind and ContainerAppAgentDefinition from AgentDefinitionUnion.
  • rename CodeInterpreterContainerAuto type (see API reference for the new type name).
  • update memory store items property type to match the latest service API (this may require code changes where items is accessed).
  • rename ImageGenActionEnum type to ImageGenAction.
  • rename project.beta.evaluators.listLatestVersions method to project.beta.evaluators.list.
  • change project.connections.get method parameter includeCredentials to be part of options bag parameter instead of a separate boolean parameter.
  • change project.connections.getDefault method parameter includeCredentials to be part of options bag parameter instead of a separate boolean parameter.

AI Projects 2.0.1 Changelog

Bugs Fixed

  • Fix polling for memory store update operations that cannot complete.

Azure Monitor OpenTelemetry 1.16.0 Changelog

Bugs Fixed

  • Fixed OpenTelemetry API version mismatch causing Noop providers in VS Code extensions. When a different version of @opentelemetry/api was already loaded (e.g. by the VS Code extension host), useAzureMonitor would silently fall back to Noop providers, discarding all telemetry. The fix clears the stale global API state before initializing the SDK.

Breaking Changes

  • Default Sampler Changed: 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 by setting tracesPerSecond: 0 which will fall back to using samplingRatio: 1.0.

Confidential Ledger 1.1.2-beta.4 Changelog

Bugs Fixed

  • Fixed redirect handling to preserve the Authorization header when Confidential Ledger redirects write operations from a secondary node to the primary node (307 redirect). Previously, the default redirect policy stripped the Authorization header, causing 401 Unauthorized errors.

Container Registry 1.1.2 Changelog

Other Changes

  • Opted in to cross-origin redirects to ensure blob downloads continue to work when the service redirects to Blob Storage. #37384
  • Updated minimum dependency on @azure/core-rest-pipeline to ^1.23.0.

Content Understanding 1.0.0 Changelog

Features Added

  • Initial release of the Azure AI Content Understanding client library for JavaScript (@azure/ai-content-understanding). This package provides ContentUnderstandingClient for analyzing documents, audio, and video content, as well as creating, managing, and configuring analyzers. Service API version 2025-11-01.

Core - Client - Core Rest Pipeline 1.23.0 Changelog

Features Added

  • Added allowCrossOriginRedirects option to RedirectPolicyOptions. #37384

Bugs Fixed

  • The redirect policy now only follows same-origin redirects by default. Set allowCrossOriginRedirects to true to restore the previous behavior. #37384

OpenTelemetry Exporter 1.0.0-beta.39 Changelog

Features Added

  • Add ownership checks for storage directories.

Bugs Fixed

  • Fixed an issue where telemetry rejected by ingestion-side sampling was incorrectly persisted for retry, causing offline storage to fill up unnecessarily.

OpenTelemetry Instrumentation 1.0.0-beta.10 Changelog

Other Changes

  • Updated @opentelemetry/instrumentation dependency to ^0.211.0.

Resource Management - Artifactsigning 1.0.0 Changelog
