The MongoDB Rust driver team is pleased to announce the v3.2.0 release of the mongodb crate, now available for download from crates.io.
Highlighted Changes
Stable API for In-Use Encryption
The API for in-use encryption is now stable and has the same backwards compatibility guarantees as the rest of the driver. To reflect this, the feature is now named in-use-encryption; in-use-encryption-unstable will continue to be provided as a compatibility alias. Please note that this is a policy change only and that the API itself has not changed from the previous release.
Improved documentation for option setters
When looking at the rustdoc for methods with chainable setters for options (e.g. Collection::find), those setters are listed directly in the rustdoc for the method rather than only being visible in the rustdoc for the type of the returned future.
Upcoming Change: EOL for Server Version 4.0
In the next minor version release (3.3.0), the Rust driver will be dropping support for connecting to mongodb server version 4.0. As of that release, the minimum supported server version will be 4.2.
