The MongoDB Go Driver Team is pleased to release version 1.11.0 of the official Go driver.
Release Notes
This release improves the Timeout API and behavior, reduces memory allocations when running most operations, and fixes several bugs. It also removes support for some legacy versions of MongoDB and Go. See below for more details.
Improve Timeout API and Behavior
Setting Timeout on a mongo.Client to enable a client-level default operation timeout is a feature added in version 1.10.0 of the driver. Various improvements have been made to this API. In particular:
- If
Timeoutis set, the driver will now retry as many times as possible before the context's deadline instead of just once. This should improve application resiliency when usingTimeout. - The
mongo.IsTimeouterror helper has been extended to catch more timeout errors. - New GridFS methods have been added that take contexts instead of using
SetReadDeadlineandSetWriteDeadline.
This feature will remain a provisional API while we gather feedback on its design and solidify our specification.
Reduce Memory Allocations
Reduce memory allocations in several critical paths in operation execution.
Fix SRV Polling
Fix a severe bug in SRV polling which may prevent changes in SRV records from updating the servers that the Go driver attempts to connect to when the MongoDB connection string includes a username and password.
Remove Support for Legacy MongoDB Versions
As of this release, the Go driver now requires MongoDB 3.6 or newer.
Remove Support for Legacy Go Versions
As of this release, the Go driver now requires Go 1.13 or newer.
Additional Features and Improvements
- Improve server-side resource cleanup when using the
Cursor.AllandSession.WithTransactionfunctions. - Add support for GCP service accounts when using GCP KMS.
- Allow specifying the
SERVICE_HOSTKerberos authentication parameter in theauthMechanismPropertiesconnection string option. - Improve error message when operations fail due to context cancellation.
