Release highlights<\/h2>\n

Azure.Core 1.51.0<\/a> for .NET<\/h3>\n

This release adds core support for Microsoft.Extensions.Configuration<\/code> and Microsoft.Extensions.DependencyInjection<\/code>, enabling better integration with ASP.NET Core applications and other .NET hosts. The update also implements support for client certificate rotation in the Azure.Core<\/code> transport layer, enabling dynamic token binding scenarios where transport instances can be updated with new client certificate configurations at runtime without requiring full pipeline reconstruction. Additionally, the release fixes a NullReferenceException<\/code> that occurred when calling GetHashCode()<\/code> on default(AzureLocation)<\/code>.<\/p>\n

corehttp 1.0.0b7<\/a> for Python<\/h3>\n

This release introduces native tracing support with OpenTelemetry integration for Python SDK operations. The new OpenTelemetryTracer<\/code> class provides a wrapper around the OpenTelemetry tracer for creating spans. SDK clients can now define an _instrumentation_config<\/code> class variable to configure the tracer, and users can configure tracing per-operation using a new TracingOptions<\/code> TypedDict. The release also includes improved exception handling with better granularity for timeout scenarios, fixes for retry policies ignoring retry_backoff_max<\/code>, and proper chaining of exceptions raised during claims challenge handling.<\/p>\n

Azure Content Understanding in Foundry Tools 1.0.0b1<\/a> for Python<\/h3>\n

This version is the initial beta release of the Azure AI Content Understanding client library for Python. The library introduces the ContentUnderstandingClient<\/code> for analyzing documents, audio, and video content using Azure AI Foundry’s content understanding capabilities. Developers can now extract meaningful insights from various content types through a unified API.<\/p>\n
