 # Release History
 
-## 0.24.0 (Unreleased)
+## 0.24.0 (2025-06-10)
 
 ### Features Added
 
 * Added a function `CosmosClient::with_connection_string` to enable `CosmosClient` creation via connection string. ([#2641](https://github.com/Azure/azure-sdk-for-rust/pull/2641))
+* Added support for executing limited cross-partition queries through the Gateway. See <https://learn.microsoft.com/rest/api/cosmos-db/querying-cosmosdb-resources-using-the-rest-api#queries-that-cannot-be-served-by-gateway> for more details on these limitations. ([#2577](https://github.com/Azure/azure-sdk-for-rust/pull/2577))
+* Added a preview feature (behind `preview_query_engine` feature flag) to allow the Rust SDK to integrate with an external query engine for performing cross-partition queries. ([#2577](https://github.com/Azure/azure-sdk-for-rust/pull/2577))
 
 ### Breaking Changes
 
-* `FeedPager<T>` now asynchronously iterates items of type `T` instead of pages containing items of type `T`. Call `FeedPager::into_pages()` to get a `PageIterator` to asynchronously iterate over all pages.
