2026-01-13

Breaking Changes

• google-cloud-sql-v1 released as 2.0.0.

  The service no longer accepts or produces a number of enum variants in SqlDSatabaseVersion.

  These variants have been removed. While we do not expect that any working application can use or receive these enum values, we bumped the major version as the change is breaking.

• google-cloud-compute-v1 released as 2.0.0.

  A small number of functions, which we expect are rarely used, changed from returning wkt::Empty to returning the unit type (). This makes the client consistent with clients for other services. We apologize for any inconvenience.

  For more details, see the 2.0.0 migration guide.

Interesting features

• The Cloud Pub/Sub preview gained a number of features, including a high-throughput Subscriber client for receiving messages from Cloud Pub/Sub.

  The Subscriber supports at-least-once delivery subscriptions. It handles lease management. It exposes flow control configuration. It includes idle stream keepalives.

  The Subscriber does not yet support stream retries (so sessions timeout after ~30 minutes), exactly-once delivery, or mocking. We are working on these.

  Your feedback is greatly appreciated while we stabilize this API!

• The Cloud Storage client now supports open_object().

  This operation allows you to open an object and then perform multiple ranged reads on the object.

  Each ranged read has lower latency than performing the read by itself.

  Note that this features is under an allow list, contact your account team to include your project into the list.

• The Google Cloud Storage client can now created signed URLs.

• Code samples showing how to use some client functions.

What's Changed

Breaking Changes

• The google-cloud-cloudsecuritycompliance-v1 crate was bumped to 2.0 because the service had breaking changes.
  • This is a Pre-GA service changes to its API are common and expected.
• google-cloud-discoveryengine-v1
  • search(), and search_lite() return pages which contain both Vec<SearchResult> and Vec<Facet>.
  • Our code generator incorrectly used the Facet as the items for search().by_items() and search_lite().by_items().
  • The current type is (naturally) SearchResult.
• We also fixed a similar problem in google-cloud-retail-v2:
  • search() also returns pages with both SearchResult and Facet lists, and the by_items() helper used the Facet whereas SearchResult is the correct element to turn into items.

New Libraries

• feat(locationfinder/v1): generate library by @coryan in #3299
• impl(compute/v1): bootstrap library by @coryan in #3383

What's Changed

• Refactor most trait implementations out of the model.rs files.

  • This reduces the file size by (approximately) a factor of 3, making it easier to read them in the documentation and to load them into IDEs.

• Using locational or regional endpoints with the StorageControl client now result in errors.

  • The service does not support these endpoints (yet).
  • The client library was erroneously using the global endpoint instead of the given locational or regional endpoints.
  • If you encounter these errors, use the default, global endpoint (storage.googleapis.com).
