Release highlights

AI Agent Server - Core 1.0.0-beta.27 Changelog

Features Added

  • Added a durable key-value state store client under Azure.AI.AgentServer.Core.Storage. FoundryStateStore.GetOrCreateAsync binds (creating if needed) a named, Foundry-backed store; instances expose async GetAsync/UpdateAsync/DeleteAsync for the store and CreateItemAsync/SetItemAsync/GetItemAsync/DeleteItemAsync/ListKeysAsync for its items, with optimistic concurrency (If-Match/ETag), optional per-user isolation, and store-level item TTL. The .NET analogue of the Python SDK’s FoundryStateStore.
  • Added support for Microsoft Entra authentication when exporting telemetry to Azure Monitor. When APPLICATIONINSIGHTS_AUTH_MODE is set to Entra, the Azure Monitor exporter attempts to use a system-assigned managed identity credential (falling back to connection-string authentication if the credential cannot be created).

App Configuration 1.11.0 Changelog

Features Added

  • Improved authentication in sovereign clouds (such as Bleu) when using a TokenCredential. Previously, if you did not set ConfigurationClientOptions.Audience, the client fell back to the Azure Public Cloud audience and authentication could fail. The client now infers the correct Microsoft Entra audience from your App Configuration endpoint, so no additional configuration is required. Public, Azure China, and Azure US Government endpoints continue to work as before, and you can still set Audience explicitly to override the inferred value.

OpenTelemetry AspNetCore 1.6.0 Changelog

Bugs Fixed

  • Hardened Azure Monitor ingestion and Live Metrics redirect handling to prevent credentials and telemetry from being forwarded to untrusted destinations. (#61244)

OpenTelemetry Exporter 1.8.3 Changelog

Bugs Fixed

  • Hardened ingestion and Live Metrics redirect handling to reject untrusted destinations before replaying telemetry or caching the redirect. Redirect targets must now use HTTPS and match an approved Azure Monitor trust boundary, preventing credentials and telemetry from being forwarded to attacker-controlled endpoints. (#61244)

Personalizer 2.0.0-beta.3 Changelog

Bugs Fixed

Breaking Changes

Features Added

Provisioning - Compute 1.0.0-beta.2 Changelog

Provisioning - Domainregistration 1.0.0-beta.1 Changelog

Resource Management - App Configuration 1.5.0-beta.2 Changelog

Resource Management - Authorization 1.2.0-beta.1 Changelog

Resource Management - Compute Fleet 1.1.0-beta.3 Changelog

Resource Management - Computelimit 1.4.0 Changelog

Resource Management - Container Service 1.6.0 Changelog

Resource Management - Cosmos DB 1.5.0 Changelog

Resource Management - Datadog 1.1.0-beta.2 Changelog

Resource Management - Enclave 1.0.0-beta.1 Changelog

Resource Management - Event Hubs 1.3.0 Changelog

Resource Management - NetApp Files 1.18.0 Changelog

Storage - Blobs 12.30.0-beta.1 Changelog

Features Added

  • Added support for service version 2026-10-06.
  • Added AccessTier, AccessTierInferred, AccessTierChangedOn, and SmartAccessTier to BlobDownloadDetails.
  • Added support for PUT blob operations returning both the existing MD5 content hash and the new CRC64 checksum.
  • Added support for Apache Arrow response format for GetBlobs and GetBlobsByHierarchy.
  • Added support for the EndBefore property in GetBlobs and GetBlobsByHierarchy. Note that EndBefore is currently only available for Apache Arrow response format and is not returned for XML response format.

Breaking Changes

  • Block IDs generated during partitioned uploads are now randomly generated instead of based on sequential integers. This ensures uniqueness across concurrent uploads to the same blob but means block IDs are no longer predictable or ordered.

Storage - Blobs Batch 12.27.0-beta.1 Changelog

Features Added

  • Added support for service version 2026-10-06.

Storage - Blobs ChangeFeed 12.0.0-preview.64 Changelog

Features Added

  • Added support for service version 2026-10-06.

Storage - Common 12.29.0-beta.1 Changelog

Features Added

  • This release contains bug fixes to improve quality.

Storage - Files Data Lake 12.28.0-beta.1 Changelog

Features Added

  • Added support for service version 2026-10-06.

Storage - Files Share 12.28.0-beta.1 Changelog

Features Added

  • Added support for service version 2026-10-06.
  • Added ShareFileClient.GetAllRangeList(), GetAllRangeListAsync(), GetAllRangeListDiff(), and GetAllRangeListDiffAsync().

Storage - Queues 12.28.0-beta.1 Changelog

Features Added

  • Added support for service version 2026-10-06.

System Events 1.1.0 Changelog

Features Added

  • Implemented IJsonModel and IPersistableModel deserialization methods for events.
