Azure SDK October 2026 Release: Cosmos DB for Rust Hits GA, Identity Security Hardened
Microsoft shipped its monthly Azure SDK index on October 28, 2026, headline feature being a stable (GA) Cosmos DB client for Rust, the language's first 1.0.0 release backed by two supporting crates. Identity security took center stage too, with Azure Core 1.63.0 for .NET adding mutual-TLS proof-of-possession while Python and Java picked up Azure Arc-managed identity support and a cross-account token-cache fix. The release also expanded Azure Provisioning betas into Databricks, Fabric, and Verified ID, and introduced a brand-new Azure Data AI category to round out the AI-and-data tooling push. All of it sits alongside the October 12 stable release of Azure MCP Server 3.0, underscoring Microsoft's push to define and operate infrastructure through both code and AI agents.
