The MongoDB Go Driver Team is pleased to release version 1.15.0 of the official Go driver.
Release Notes
This release adds a feature that can prevent "connection churn" caused by operation timeouts.
Prevent "Connection Churn" Caused by Timeouts
Previously, the Go Driver would close the in-use connection when an operation timed out. However, closing the in-use connection can cause significant additional application and database load if many timeouts happen quickly, potentially causing "connection churn" that can exacerbate latency issues. The Go Driver now offers a new feature that waits (for a maximum of 1 second) for the connection to be reusable after an operation times out instead of closing it.
To enable the new feature, set a Client-wide timeout by using SetTimeout or by specifing the timeoutMS connection string option. Use SetTimeout(0) or timeoutMS=0 to enable the new feature without adding new timeouts. See SetTimeout for more information about the Client-wide timeout configuration.

⚠️ Retracted
v1.13.0 has been retracted because the Github tag was modified, leading to a security error when dowloading the Go module. The original tag does not include all changes intended for v1.13.0 and should not be used.
Please use version 1.13.1 or higher.
The MongoDB Go Driver Team is pleased to release version 1.13.0 of the official Go driver.
Release Notes
This release enhances logging, search index management, and command events. This release also introduces smarter server selection for sharded clusters, optimizing retry selection. Additionally, we streamline resource usage on FaaS platforms by disabling streaming SDAM and introduce the serverMonitoringMode=stream/poll/auto URI option.
Logging
In this release, we add logging for server selection and SDAM (Server Discovery and Monitoring). See the Go Driver logging documentation for usage.
Search Index Management Helpers
New mongo.Collection methods have been added to support search index management. For more information on search indexes, see the documentation here.
Users can create and manage search indexes programmatically. This update provides more flexibility and a smoother user experience, allowing you to define your search index within your code.
Include DatabaseName in Command Events
DatabaseName is now returned by event.CommandStartedEvent and event.CommandFinishedEvent. This field will also be included in the command logging analogues. This addition will improve performance for users needing to keep a thread-safe map to maintain command-database relations, whereas now such a map can be deprecated.
Possible Retries to Alternate Mongos for Read/Write
In sharded MongoDB cluster deployments, it's essential to avoid repeatedly selecting a failing mongos instance. Currently, the driver randomly selects a mongos for each operation, which can lead to retrying failed operations with the same problematic mongos. This enhancement introduces smarter server selection for sharded topologies:
- The driver will distinguish between the initial attempt and a retry.
- It will remember the server used for the initial attempt.
- When retrying, if multiple eligible mongos servers are available, the driver will select randomly from the healthy ones, excluding the previously used server.
The driver can assess mongos health before attempting a query and exclude unhealthy mongos from selection.
Transition to Polling Monitoring in FaaS Environments
In this release, we make important changes to enhance performance and flexibility. By default, streaming SDAM is now disabled on AWS Lambda and similar FaaS platforms, ensuring efficient resource utilization. We also introduce the serverMonitoringMode=stream/poll/auto URI option to give you greater control over monitoring modes. To improve client behavior, we mandate that clients refrain from using dedicated connections to measure Round-Trip Time (RTT) when employing the polling protocol. These updates aim to provide a more versatile and efficient experience for users.

The MongoDB Go Driver Team is pleased to release version 1.12.1 of the official Go driver.
Release Notes
This release fixes a bug in the Go Driver where connections are leaked if a user runs a transaction while connected to a load balancer. To resolve this issue, the Go Driver will now unpin connections when ending a session.
This release fixes a logging design oversight in which enabling logging with options.LogComponentAll does not result in the publication of logs.
This release fixes two runtime errors, which occur on unmarshaling an empty bson.RawValue with an invalid type, specifically the 0x00 (null) type, and on marshaling a nil pointer of ReadConcern.

MongoDB Go Driver 1.12.0

The MongoDB Go Driver Team is pleased to release version 1.12.0 of the official Go driver.
Release Notes
This release adds support for MongoDB 7.0, including production-ready support for Queryable Encryption. It also adds a new logging interface and configuration API improvements.
Production-Ready Queryable Encryption
This release introduces backwards breaking changes to the Queryable Encryption protocol. Using Queryable Encryption now requires MongoDB 7.0+ and libmongocrypt v1.8.0+.
It also adds the new ClientEncryption.CreateEncryptedCollection method to automatically create data encryption keys when creating a new encrypted collection and adds the ability to fetch KMS credentials automatically from Azure, GCP, and AWS environments.
Logging
This release introduces a logging interface to allow users to more easily record detailed information about connection management and command execution within their application.
The logging configuration adds a new LogSink interface that is compatible with the logr.LogSink interface, allowing users to use existing logr adapters, like zerologr or zapr. Users may also implement their own LogSink adapter.
For example, to integrate logging with an existing zerolog logger:
sink := zerologr.New(&myLogger).GetSink()
loggerOptions := options.Logger().SetSink(sink)
options.Client().SetLoggerOptions(loggerOptions)Logging can also be enabled using environment variables. For example, to enable command logging at info level to client.log, set:
export MONGODB_LOG_COMMAND=info
export MONGODB_LOG_MAX_DOCUMENT_LENGTH=100
export MONGODB_LOG_PATH="client.log"
Convenient BSON Options
The options package has a new way to set various BSON marshaling and unmarshaling behaviors.
For example, to set BSON options that cause the Go driver to fallback to "json" struct tags if "bson" struct tags are missing, marshal nil Go maps as empty BSON documents, and marshals nil Go slices as empty BSON arrays, use the new options.BSONOptions configuration:
bsonOpts := &options.BSONOptions{
UseJSONStructTags: true,
NilMapAsEmpty: true,
NilSliceAsEmpty: true,
}
options.Client().SetBSONOptions(bsonOpts)Convenient Write Concerns
The writeconcern package has new convenience functions Majority, W1, Journaled, and Unacknowledged for creating common write concerns.
For example, to configure a Client to use write concern {w: 1}, use the new writeconcern.W1() function:
options.Client().SetWriteConcern(writeconcern.W1())Additional Changes
- Support authenticating with AWS IAM roles in EKS.
- Add
SetBatchSizetoCursorto allow specifying the size of batches fetched from the database when iterating a cursor. It is primarily intended for use with cursors returned by RunCommandCursor. - Add
bson.UnmarshalValueto allow unmarshaling BSON values that were marshaled using the existing bson.MarshalValue. - Deprecate various APIs that will be replaced or removed in Go Driver v2.0.
