Azure SDK Release (October 2025) released
Microsoft has released the latest October 2025 update to its Azure SDKs, which includes an array of new features, improvements, and bug fixes to enhance developer experience. Developers can find comprehensive information on package links, code, and documentation through the Azure SDK Releases page.
Notable highlights from this release include:
The stable launch of Azure AI Foundry 1.0.0 for .NET provides extensive access to Azure AI Foundry Project resources. This library empowers developers with a range of functionalities, including creating and running AI agents, managing AI model deployments, establishing connections to Azure resources, uploading documents and creating datasets, and managing search indexes. Key enhancements include consistent API improvements through the introduction of an AIProject prefix for key models (AIProjectDeployment, AIProjectConnection, AIProjectIndex), streamlined client access via direct properties on AIProjectClient (replacing individual Get*Client methods), and new CreateOrUpdate methods for index management. The library is built upon the v1 AI Foundry data plane REST APIs and supports secure authentication through Microsoft Entra ID.
Azure AI Search has also seen significant upgrades with the release of version 12.2.0 for JavaScript. This update introduces support for the 2025-09-01 service version, offering several key enhancements, including the ability to run vector queries against sub-fields of complex fields, reranker boosted scores in search results with the option to sort on either reranker or reranker boosted scores, and improved vector compression configuration through RescoringOptions. Additionally, this release introduces LexicalNormalizer support for text analysis, a new DocumentIntelligenceLayoutSkill for skillsets, and OneLake data source connections for indexers.
In parallel, version 11.6.0 of the Azure AI Search library for Python has been updated to support the 2025-09-01 service version, mirroring the JavaScript release. Key features include vector query support for complex field subfields, semantic ranking enhancements with reranker boosted scores, vector compression rescoring options, lexical normalizers for improved text processing, and the new DocumentIntelligenceLayoutSkill. This release also adds QueryDebugMode support for detailed vector search debugging information.
The Azure Identity libraries have undergone performance improvements for managed identity scenarios across various languages:
C++ has been upgraded to 1.13.2 Go now boasts version 1.13.0 Java has reached 1.18.1 JavaScript is at 4.13.0 Python is at 1.25.1
These updates greatly improve performance for managed identity situations, as DefaultAzureCredential now avoids the IMDS endpoint check and goes straight to getting a token with complete retry logic and gradual delays when the environment variable AZURE_TOKEN_CREDENTIALS is set to ManagedIdentityCredential.
Some notable initial stable releases include:
The client library for .NET has seen several library upgrades: The AI Foundry 1.0.0 library provides comprehensive access to Azure AI resources. AI VoiceLive 1.0.0 enables developers to manage and interact with AI-powered voice services.
Management Library for .NET also boasts several key initial stable releases, including
Resource Management – Data Migration 1.0.0 Resource Management – Site Manager 1.0.0
Other initial stable releases can be found in the Go, Java, JavaScript, Python, the Client Library for .NET, and the Management Library for various languages.
Additionally, some libraries have reached their first beta release: Management Library for .NET has seen two key beta releases: Resource Management – Disconnected Operations 1.0.0-beta.1 and Resource Management – Compute.Recommender 1.0.0-beta.1. Management Library for Go now boasts a beta release of Resource Management – Recommender 0.1.0 Management Library for Java has reached a beta release of Resource Management – Compute-Recommender 1.0.0-beta.1
