The MongoDB driver for Go

Add support for some mongodb 4.0 features, but only at an experimental stage.

add func:

// UpdateWithArrayFilters allows passing an array of filter documents that determines
// which array elements to modify for an update operation on an array field. The multi parameter
// determines whether the update should update multiple documents (true) or only one document (false).
// 
// See example: https://docs.mongodb.com/manual/reference/method/db.collection.update/#update-arrayfiltersi
// 
// Note this method is only compatible with MongoDB 3.6+.
func (c *Collection) UpdateWithArrayFilters(selector, update, arrayFilters interface{}, multi bool) (*ChangeInfo, error)

GoDoc.

A sub-package that implements the BSON specification is also included, and may be used independently of the driver.
