The MongoDB Go driver team is pleased to release 1.3.0 of the official Go driver.

This release contains new functions to construct BSON registries, a new BSON registry that mimics the behavior of the globalsign/mgo/bson library, and new URI options to specify TLS certificates and keys as separate files. As part of this release, support for Go modules has been added and the README has been changed to reflect this. There is still a vendor directory in the source code so projects can be compiled with versions of Go that do not support modules.

Documentation can be found on GoDoc and the MongoDB documentation site. BSON library documentation is also available on GoDoc. Questions and inquiries can be asked on the mongo-go-driver Google Group. Bugs can be reported in the Go Driver Jira where a list of current issues can be found.

mgo compatible BSON

A new mgocompat package has been added under the top-level bson package. This package exports Registry, which is a BSON registry compatible with globalsign/mgo/bson and RegistryRespectNilValues, which is compatible with globalsign/mgo/bson with the RespectNilValues flag set to true. These registries can be used via the ClientOptions.SetRegistry method. The package also exports a RegistryBuilder for each of the registries so additional changes can be made. See the bson/bsoncodec package documentation for more information.

RegistryBuilder method changes

The existing RegisterEncoder methods has been deprecated and replaced by RegisterTypeEncoder and RegisterHookEncoder. A corresponding change has been made for RegisterDecoder as well.
