      Description

      The 3.12 release introduces the UuidRepresentation setting for MongoClient but leaves the default as JAVA_LEGACY.  In 4.0, we will change the default to UNSPECIFIED.

      This is an intentional backwards-breaking change to make all UUID-supporting drivers use a consistent UUID representation.
