0.31.0 (2026-02-25)

Features Added

• Added with_excluded_regions to ItemOptions for additional regional routing options. (#3602)
• Added effective_preferred_regions to the client, ensuring multi-region accounts use all regions for cross-regional availability without supplying regional preferences to their client. (#3602)
• Added basic multi-region writes support. (#3482 and #3495)
• Added new CosmosResponse that wraps azure_core::Response for all operations except queries. (#3622)
• Added transactional batch support for executing multiple operations atomically within the same partition key. (#3664)
• Added fault injection support for testing cosmosdb clients in disaster scenarios. Fault injection is behind the feature flag fault_injection. (#3599)

Breaking Changes

• Changed our minimum supported Rust version (MSRV) from 1.85 to 1.88.
• Removed ContainerClient::patch_item, PatchDocument, and PatchOperation temporarily to redesign the PATCH API for safe idempotency. Use a Read/Modify/Replace model with ETag-based optimistic concurrency instead.
• Changed return type of query methods from FeedPager<T> (an alias for ItemIterator<FeedPage<T>, String>) to FeedItemIterator<T>, which implements Stream<Item = Result<T>> and provides into_pages() for page-level access. (#3515)
• Introduced CosmosClientBuilder for constructing CosmosClient instances, replacing constructor-based API. Removed consistency_level, priority, throughput_bucket, excluded_regions, SessionRetryOptions, triggers, and IndexingDirective from options. Simplified CosmosAccountReference to take CosmosAccountEndpoint directly. Made option struct fields private with getters and with_* setters. (#3744)
• Removed with_application_preferred_regions API. Use with_application_region to set the Azure region the app is executing in (or the closest region to the actual location you're running in); the SDK generates preferred regions by geographic proximity. (#3796)
• Made CosmosClientBuilder::build() and DatabaseClient::container_client() async to prepare for future cache population (account, collection, partition key range caches).
• Support for wasm32-unknown-unknown has been removed (#3377)

Other Changes

• Added default HTTP client timeouts and added retries for connection errors. (#3752)
• Retry policies now retry reads on all non-whitelisted status codes and retry service unavailable errors across all applicable endpoints. (#3728)

0.3.0 (2026-02-11)

Features Added

• Added support for queue client construction directly from URLs: QueueClient::from_url()
• Added support for SAS (shared access signature) URLs via the new from_url() methods.
• Added continuation_token to PagerOptions for methods that return a Pager.

Breaking Changes

• Changed QueueClient::set_access_policy() return type from Response<QueueClientSetAccessPolicyResult, NoFormat> to Response<(), NoFormat>.
• Changed our minimum supported Rust version (MSRV) from 1.85 to 1.88.
• Removed the queue_name() accessor on QueueClient.
• Removed the endpoint struct field on all clients, as this value is now returned directly from the underlying generated client.
• Changed the queue_name parameter from owned String to &str reference on QueueClient::new().
• The credential parameter is now Option<Arc<dyn TokenCredential>> on new() and from_url() client constructors, allowing for construction of public access clients and clients using SAS tokens.
• Changed QueueServiceClient::queue_client() to return Result<QueueClient> instead of QueueClient.
• Removed Pager::with_continuation_token() for methods that return a Pager.
