Azure SDK Release (September 2026)

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.

This roundup includes initial releases that were publicly available before September but weren’t listed in an earlier post. Each package version appears here only once, including releases absent from the monthly release-data feed when we checked it.

Release highlights

Azure AI Search 12.1.0-beta.2

The latest Azure AI Search previews add support for the 2026-08-01-preview service API across .NET, Java, JavaScript, and Python. They expand file knowledge-source management and knowledge base retrieval, including streamed retrieval responses in the JavaScript library. If you built against an earlier preview, review the changed listing parameters and other preview-only API changes before upgrading; these changes don’t affect the stable Python API.

Azure Storage SAS 1.0.0

The Rust crate for building Azure Storage shared access signatures reached its first stable release. It fixes SAS generation for blob and directory paths containing backslashes by normalizing the signed resource path. Preview users must also update imports for UserDelegationKey, which now comes from azure_storage_common::models instead of a re-export from azure_storage_sas.

PostgreSQL Authentication 1.0.0

The .NET Entra ID authentication extension for the Npgsql PostgreSQL driver reached its first stable release, alongside the JavaScript PostgreSQL authentication library 1.0.0. JavaScript users upgrading from the preview should note that the minimum supported Node.js version is now 22; its API surface otherwise remains unchanged.
