+* Unvendor'd text-format, now requires text-format gem
* Whole new API added with tests. See base.rb for full details. Old API is deprecated.
* The Mail::Message class has helped methods for all the field types that return 'common' defaults for the common use case, so to get the subject, mail.subject will give you a string, mail.date will give you a DateTime object, mail.from will give you an array of address specs (email@example.com) etc. If you want to access the field object itself, call mail[:field_name] which will return the field object you want, which you can then chain, like mail[:from].formatted
