Release highlights<\/h2>\n

Azure Identity 1.19.0 for .NET<\/a><\/h3>\n

The Azure Identity library for .NET now supports specifying a certificate path in the form of cert:\/StoreLocation\/StoreName\/Thumbprint<\/code> when using ClientCertificateCredential<\/code>. This feature allows you to reference a certificate directly from the platform certificate store, such as the Windows Certificate Store or the macOS KeyChain, instead of requiring a file on disk. For example, to load a certificate from the “My” store in the “CurrentUser” location, use the path cert:\/CurrentUser\/My\/E661583E8FABEF4C0BEF694CBC41C28FB81CD870<\/code>.<\/p>\n

Cosmos DB 0.31.0 for Rust<\/a><\/h3>\n

The Azure Cosmos DB client library for Rust adds several significant features and breaking changes in this release. New capabilities include basic multi-region writes support, transactional batch support for executing multiple operations atomically within the same partition key, and fault injection support for testing in disaster scenarios. The client construction API was redesigned with a new CosmosClientBuilder<\/code>, and query methods now return a FeedItemIterator<T><\/code> implementing Stream<Item = Result<T>><\/code>. Note that wasm32-unknown-unknown<\/code> support was removed across the Rust SDK.<\/p>\n

Content Understanding 1.0.0 for .NET<\/a><\/h3>\n

Azure AI Content Understanding reaches general availability for .NET, JavaScript, and Python. This library provides a ContentUnderstandingClient<\/code> for analyzing documents, audio, and video content, as well as creating, managing, and configuring analyzers. The .NET release includes strongly typed Value<\/code> properties on ContentField<\/code> subclasses, a ContentSource<\/code> hierarchy for strongly typed parsing of grounding source strings, and ContentRange<\/code> value type with static factory methods for specifying content ranges.<\/p>\n
