v2.12.0

The MongoDB Rust driver team is pleased to announce the v2.12.0 release of the bson crate.

Highlighted Changes

This release was largely driven by external contributions!

• An optional implementation of Hash and Eq for the Bson family of types
• ObjectId::from_parts, allowing direct construction of an ObjectId from its component values
• Helpers for serializing Option<chrono::DateTime<_>> as Option<bson::DateTime>
• A fix for a panic when parsing specific malformed input data into a Decimal128

We've also added optional (off by default) integration with the serde_path_to_error crate, which
provides paths to the precise point of failure for deserialization of nested data structures.
