Also, a unmarshaler for gridfs.File is added. *** For a full list of tickets included in this release, please see the [list of fixed issues](https://jira.mongodb.org/issues/?jql=project%3Dgodriver%20and%20fixVersion%3D2.2.2). **Full Changelog**: [v2.2.1...v2.2.2](mongodb/mongo-go-driver@v2.2.1...v2.2.2) Documentation for the Go Driver can be found on [pkg.go.dev](https://pkg.go.dev/go.mongodb.org/mongo-driver/v2/mongo?tab=doc) and the [MongoDB documentation site](https://docs.mongodb.com/ecosystem/drivers/go/).

Note that further regressions from version 1 may be addressed in GODRIVER-3450, with this update focusing on reinstating optimizations removed in the version 2 implementation. Performance may not be 1-1 with v1 since v2 suggests using the `bufio` package for byte management rather than a raw byte slice. #### What's Changed - GODRIVER-3546 Fix timeouts in CSE custom endpoint test ([#​2028](mongodb/mongo-go-driver#2028)) by [@​prestonvasquez](https://github.com/prestonvasquez) in [#​2031](mongodb/mongo-go-driver#2031) - GODRIVER-3533 Optimize value reader and writer ([#​2022](mongodb/mongo-go-driver#2022)) by [@​prestonvasquez](https://github.com/prestonvasquez) in [#​2030](mongodb/mongo-go-driver#2030) - DEVPROD-17319 Update perf.send command to new results end point by [@​prestonvasquez](https://github.com/prestonvasquez) in [#​2032](mongodb/mongo-go-driver#2032) **Full Changelog**: <mongodb/mongo-go-driver@v2.2.0...v2.2.1> **JIRA Release Notes**: <https://jira.mongodb.org/projects/GODRIVER/versions/43096> Documentation for the Go Driver can be found on [pkg.go.dev](https://pkg.go.dev/go.mongodb.org/mongo-driver/v2/mongo?tab=doc) and the [MongoDB documentation site](https://docs.mongodb.com/ecosystem/drivers/go/).

We have implemented support for [`errors.Is`](https://pkg.go.dev/errors#Is) and [`errors.As`](https://pkg.go.dev/errors#As) in all stable public APIs for improved error management. Also included is support to configure the lifetime of the [Data Encryption Key (DEK)](https://www.mongodb.com/docs/manual/core/csfle/fundamentals/manage-keys/) cache as well as [Kubernetes Support for OIDC](https://www.mongodb.com/docs/drivers/go/current/fundamentals/enterprise-auth/#kubernetes). Additionally **MongoDB Server Version 3.6** has been marked as end-of-life (EOL) and is no longer supported by the driver. Users are advised to upgrade to a supported version. *** For a full list of tickets included in this release, please see the links below: - [New Features](https://jira.mongodb.org/issues/?jql=project%3Dgodriver%20and%20type%3D%22new%20feature%22%20and%20status%20%3D%20Closed%20and%20fixVersion%3D2.2.0) - [Improvements](https://jira.mongodb.org/issues/?jql=project%3Dgodriver%20and%20type%3Dimprovement%20and%20status%20%3D%20Closed%20and%20fixVersion%3D2.2.0) - [Bugs](https://jira.mongodb.org/issues/?jql=project%3DGODRIVER%20and%20type%3DBug%20and%20status%3Dclosed%20and%20fixVersion%3D2.2.0) - [Tasks](https://jira.mongodb.org/issues/?jql=project%3Dgodriver%20and%20type%3D%22task%22%20and%20status%20%3D%20Closed%20and%20fixVersion%3D2.2.0) **Full Changelog**: [v2.1.0...v2.2.0](mongodb/mongo-go-driver@v2.1.0...v2.2.0) **Note**: The Go Driver team has implemented a workflow action to automatically merge up PRs between v1 and master.

In contrast, the existing [Collection.BulkWrite](https://pkg.go.dev/go.mongodb.org/mongo-driver/v2/mongo#Collection.BulkWrite) method can only modify a single collection. ##### BSON Vector Datatype The new [bson.Vector](https://pkg.go.dev/go.mongodb.org/mongo-driver/v2/bson#Vector) type makes inserting and querying vector data using [Atlas Vector Search](https://www.mongodb.com/docs/atlas/atlas-vector-search/vector-search-overview/) easier and more efficient. *** For a full list of tickets included in this release, please see the links below: - [New Features](https://jira.mongodb.org/issues/?jql=project%3Dgodriver%20and%20type%3D%22new%20feature%22%20and%20status%20%3D%20Closed%20and%20fixVersion%3D2.1.0) - [Improvements](https://jira.mongodb.org/issues/?jql=project%3Dgodriver%20and%20type%3Dimprovement%20and%20status%20%3D%20Closed%20and%20fixVersion%3D2.1.0) - [Bugs](https://jira.mongodb.org/issues/?jql=project%3DGODRIVER%20and%20type%3DBug%20and%20status%3Dclosed%20and%20fixVersion%3D2.1.0) - [Tasks](https://jira.mongodb.org/issues/?jql=project%3Dgodriver%20and%20type%3D%22task%22%20and%20status%20%3D%20Closed%20and%20fixVersion%3D2.1.0) **Full Changelog**: [v2.0.1...v2.1.0](mongodb/mongo-go-driver@v2.0.1...v2.1.0) Documentation for the MongoDB Go Driver can be found on [pkg.go.dev](https://pkg.go.dev/go.mongodb.org/mongo-driver/v2/mongo) and the [MongoDB documentation site](https://docs.mongodb.com/ecosystem/drivers/go/).

Your feedback on the MongoDB Go Driver is greatly appreciated! ### [`v2.0.0`](https://github.com/mongodb/mongo-go-driver/releases/tag/v2.0.0): MongoDB Go Driver 2.0.0 [Compare Source](mongodb/mongo-go-driver@v1.17.7...v2.0.0) The MongoDB Go Driver Team is pleased to release version 2.0.0 of the official MongoDB Go driver. #### Release Notes This release includes a host of new features and several breaking changes. Below, we provide an overview of the key highlights, changes, and guidance for migrating from version 1.x to 2.0. See the [MongoDB docs](https://www.mongodb.com/docs/drivers/go/upcoming/whats-new/#what-s-new-in-2.0) for a complete list of breaking changes and additional information on what's new. This release includes several breaking changes that users must account for when upgrading, including: - **Options Package**: The approach to managing options has been restructured to use a builder pattern, changing how options are constructed and applied. This alteration allows for more flexible and dynamic option configurations, but may require changes to existing code that directly manipulates options objects. - **Mongo Package**: The `Client.Connect()` method has been removed, favoring `mongo.Connect()` to streamline connection handling. - **Event Package**: References to the `description` package have been transitioned to `event.ServerDescription` and `event.TopologyDescription`, impacting how server and topology details are accessed. - **BSON Package Consolidation**: All previously separate BSON-related packages, including `bsoncodec`, `bsonoptions`, `bsonrw`, and `mgocompat`, have been merged into the single `bson` package. Many functionalities from these packages have been reorganized or renamed. For instance, `bson.NewRegistryBuilder` has been replaced with new APIs tailored for registry configuration, and interfaces like `ValueReader` and `ValueWriter` are now part of the consolidated `bson` package. This consolidation simplifies the package structure but requires updates to import paths and related logic. To ease the transition to 2.0, **a comprehensive [migration guide](https://github.com/mongodb/mongo-go-driver/blob/master/docs/migration-2.0.md) has been provided**. This guide includes detailed instructions to navigate the changes, including the updated options pattern, altered imports, and revised method signatures. Additionally, this release deprecates support for MongoDB server versions below 3.6. Support for MongoDB 3.6 will be dropped in a future update. New features will no longer be added to the 1.x versions. However, critical bug fixes and CVE resolutions will continue to be back-ported to 1.x versions for one year until January 15, 2026. After that date, support for 1.x versions will be discontinued. We express our gratitude to our contributors and the community for all the support in developing this release. *** For a full list of tickets included in this release, please see the links below: - [Projects](https://jira.mongodb.org/issues/?jql=project%3Dgodriver%20and%20type%3Depic%20and%20status%20%3D%20Closed%20and%20fixVersion%3D2.0.0) - [New Features](https://jira.mongodb.org/issues/?jql=project%3Dgodriver%20and%20type%3D%22new%20feature%22%20and%20status%20%3D%20Closed%20and%20fixVersion%3D2.0.0) - [Improvements](https://jira.mongodb.org/issues/?jql=project%3Dgodriver%20and%20type%3Dimprovement%20and%20status%20%3D%20Closed%20and%20fixVersion%3D2.0.0) - [Bugs](https://jira.mongodb.org/issues/?jql=project%3DGODRIVER%20and%20type%3DBug%20and%20status%3Dclosed%20and%20fixVersion%3D2.0.0) - [Tasks](https://jira.mongodb.org/issues/?jql=project%3Dgodriver%20and%20type%3D%22task%22%20and%20status%20%3D%20Closed%20and%20fixVersion%3D2.0.0) **Full Changelog**: [v1.17.1...v2.0.0](mongodb/mongo-go-driver@v1.17.1...v2.0.0) Documentation for the Go driver can be found on [pkg.go.dev](https://pkg.go.dev/go.mongodb.org/mongo-driver/mongo?tab=doc) and the [MongoDB documentation site](https://docs.mongodb.com/ecosystem/drivers/go/).
