Thank you for your interest in the new Azure SDKs! We release new features, improvements, and bug fixes every month. Subscribe to our Azure SDK Blog RSS Feed to get notified when a new release is available. You can find links to packages, code, and docs on our Azure SDK Releases page.

Release highlights

The Azure SDK for Rust reaches general availability

The Azure SDK for Rust is now stable. This month's GA delivers production-ready 1.0.0 crates for Core, Identity, Key Vault (Secrets, Keys, and Certificates), and Storage (Blobs and Queues), built on the same design patterns you already know from the .NET, Java, JavaScript, Python, Go, and C++ SDKs. For the full story, see From beta to stable: Announcing the Azure SDK for Rust.

Azure AI Search adds agentic retrieval with knowledge bases

The .NET Azure AI Search library (12.0.0) and Python azure-search-documents (12.0.0) introduce knowledge bases and a new KnowledgeBaseRetrievalClient for agentic retrieval. You can now define knowledge sources backed by Azure Blob storage, a search index, OneLake, or the web, then run retrieval requests against a knowledge base, all on the new 2026-04-01 service version. The JavaScript @azure/search-documents (13.0.0) release adds a debug property to inspect non-semantic search queries and an oversampling option for vector search.

New Azure AI Agent Server libraries enter preview

A new family of preview libraries for hosting agents arrived this month, led by .NET Azure.AI.AgentServer.Core (1.0.0-beta.23) and Python azure-ai-agentserver-core (2.0.0b3). .NET also ships companion Invocations and Responses packages, while Python ships a companion Responses package this month. They provide an AgentServerHost hosting model with built-in health probes, graceful shutdown, request-ID middleware, and a centralized PlatformHeaders set of HTTP header constants shared across the packages. As preview releases, these libraries are still changing quickly; the latest .NET beta, for example, consolidated six separate setup calls into a single AddAgentServerCore() / UseAgentServerCore() pair.

Azure Batch client library reaches general availability for .NET

The .NET Azure.Compute.Batch (1.0.0) library is now generally available. The GA release includes breaking changes carried over from beta, including the removal of AuthenticationTokenSettings and BatchAccessScope and a number of property renames (such as BatchJobScheduleConfiguration.DoNotRunUntil to DoNotRunBefore). Cross-language Batch modernization continued as well with JavaScript @azure/batch (13.0.0) and Python azure-batch (15.1.0), which ship their own type and option renames.
