This change adds the ability to properly parse messages where the parent message's content-type is set to multipart/alternative into multiple Part objects. Previously, this content-type header would be ignored, leaving alternative parts being rolled into one single Part object. See 7.2.3 The Multipart/alternative subtype for more information.
At the moment, I don't know if this will cause an effective BC break.
