It also fixes delays in DefaultAzureCredential when the Instance Metadata Service (IMDS) is unavailable and prevents unavailable managed identity sources from prematurely aborting the credential chain. If you use the experimental managed identity proof-of-possession option, replace DisableMtlsProofOfPossession = true with EnableMtlsProofOfPossession = false to continue forcing bearer authentication.Identity 1.26.0 for PythonManagedIdentityCredential now supports user-assigned managed identities on Azure Arc-enabled servers, selectable by client ID, object ID, or resource ID. Token responses that don't confirm the requested identity are rejected. This release also fixes synchronous Service Fabric managed identity authentication with MSAL 1.39.0 and later, and a shared-token-cache issue where AuthorizationCodeCredential and the asynchronous OnBehalfOfCredential could return a cached token for another account. Identity 1.18.7 for Java adds Azure Arc user-assigned managed identity support to both ManagedIdentityCredential and DefaultAzureCredential, alongside fixes for native-image compatibility and IMDS discovery timeouts.Cosmos DB 1.0.0 for RustThe Cosmos DB library for Rust reaches its first stable release alongside the Cosmos DB Client Driver and SDK Macros crates. When upgrading from the preview, rename the preview_dtx, preview_patch, and preview_opentelemetry feature flags to their unstable_ equivalents, and replace CosmosCredential::MasterKey with CosmosCredential::AccountKey. The release also changes the User-Agent format and maps specific terminal service errors to synthetic 503 errors, retaining the original wire error in source().Initial stable releases Management Library for .NET Resource Management - Napster Omni Agent API 1.0.0 Management Libraries for Java Resource Management - Relationships 1.0.0 Resource Management - Service Groups 1.0.0 Resource Management - Template Specs 1.0.0 Management Libraries for JavaScript Resource Management - Relationships 1.0.0 Resource Management - Service Groups 1.0.0 Resource Management - Resilience Management 1.0.0 Management Libraries for Python Resource Management - Resource-Policy 1.0.0 Resource Management - Relationships 1.0.0 Resource Management - Features 1.0.0 Resource Management - Locks 1.0.0 Resource Management - Template Specs 1.0.0 Management Libraries for Go Resource Management - Relationships 1.0.0 Resource Management - Service Groups 1.0.0 Resource Management - Resilience Management 1.0.0 Client Libraries for Rust Cosmos DB 1.0.0 Cosmos DB Client Driver 1.0.0 Cosmos DB SDK Macros 1.0.0Initial beta releases Client Libraries for .NET Web PubSub Chat 1.0.0-beta.1 Provisioning - Databricks 1.0.0-beta.1 Azure Data AI 1.0.0-beta.1 AI Agent Server - Optimization 1.0.0-beta.1 Provisioning - Fabric 1.0.0-beta.1 Provisioning - Verified ID 1.0.0-beta.1 Management Libraries for Java Resource Management - Platform Validation 1.0.0-beta.1 Resource Management - Compute Workload Manager 1.0.0-beta.1 Client Libraries for JavaScript Azure AI Content Safety 1.0.0-beta.1 Provisioning 1.0.0-beta.1 Provisioning - Key Vault 1.0.0-beta.1 Management Libraries for JavaScript Resource Management - Compute Workload Manager 1.0.0-beta.1 Resource Management - Platform Validation 1.0.0-beta.1 Resource Management - Secrets Store Extension 1.0.0-beta.1 Client Libraries for Python Azure AI Fine-Tuning Sessions 1.0.0b1 Azure Data AI 1.0.0b1 Web PubSub Chat 1.0.0b1 Management Libraries for Python Resource Management - Platform Validation 1.0.0b1 Resource Management - Compute Workload Manager 1.0.0b1 Client Library for Go azure/sdk/storage/internal 0.1.0 Management Library for Go Resource Management - Platform Validation 0.1.0 Client Libraries for Rust Cosmos DB Client Driver 1.0.0-beta.1 Cosmos DB SDK Macros 1.0.0-beta.1 Cosmos DB 1.0.0-beta.1Release notes All languages .NET Java JavaScript/TypeScript Python Go Rust C++
