Major changes:
- Support for Gmail's XOAUTH2 authentication system, thanks to @sherryl4george. Use of this feature requires PHP 5.4 or later. Read the docs.
- PHP7 is officially supported. Test suite is now run on PHP 7 and passes applicable php7cc checks.
Minor changes:
- Can now convert addresses from RFC822 format (e.g.
User Name <user@example.com>) - Fix some quoted-printable & line-length edge cases.
- Work-around for invalid MS Exchange AUTH implementation.
