      Rust SDK 1.0 Releases

      Version 1.0 of the Rust SDK implements the 3.9 SDK API. See the compatibility pages for more information on feature compatibility with different versions of Couchbase Server.

      We always recommend using the latest version of the SDK — it contains all of the latest security patches and support for new and upcoming features. All patch releases for each dot minor release should be API compatible, and safe to upgrade; any changes to expected behavior are noted in the release notes that follow.

      Binary compatibility is not guaranteed for any Rust SDK release, and you should rebuild your application when changing the SDK.
