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

This alpha release contains major updates to the mongo package and BSON library. Additionally, there are small API updates and bug fixes. This is alpha software, so it is not recommended for production use.

Following semver, the v0 version of the public API should not be considered stable and could change.

Documentation can be found 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.

BSON Library Changes

The Document, Element, Value, and Array types have been redesign and rewritten. They have been moved from the bson package to the x/bsonx package and renamed Doc, Elem, Val, and Arr respectively. These types are still under development and are likely to change.

The BSON primitive types have been moved from the bson package to a new package called primitive. For example the bson.Regex type is now the primitive.Regex type.

Mongo API Changes

Options for the mongo package have been redesigned. Instead of individual packages for groups of option types, there is a single options package that contains all options. Please refer to the GoDoc page for more details.
