The MongoDB Go Driver Team is pleased to release version 2.6.1 of the MongoDB Go Driver.
This release fixes batched writes to split by full wire-message size instead of document payload size, preventing near-limit InsertMany failures; fixes unmarshaling of null and undefined values into raw BSON types such as bson.Raw, bsoncore.Document, and bsoncore.Array; and fixes mongo.ErrorCodes() to return codes for ClientBulkWriteException, including duplicate-key errors from client bulk writes.
WARNING: This release changed bson.Raw unmarshaling for BSON null values from the long-standing V2 behavior of Raw{} to Raw(nil). Decoding to Raw{} was a bug and was inconsistent with other container types. If you added checks or workarounds that depend on Raw{}, update them to expect Raw(nil) (or nil) after upgrading.
You can obtain the driver source from GitHub under the v2.6.1 tag.
Documentation for the Go Driver can be found on pkg.go.dev and the
MongoDB documentation site.
BSON library documentation is also available on pkg.go.dev.
