Release Notes

* Added a work-around for Exchange IMAP servers that send broken multipart BODYSTRUCTURE responses without a `body-fld-dsp` token.
* Added support for detecting (but not using) the UNAUTHENTICATE IMAP extension.
* Reintroduced the Pop3Client.GetMessageCount[Async]() methods to allow developers to poll POP3 servers for new messages. (issue #762)
* Fixed SmtpClient's status code logic to handle more than the expected error codes for the `MAIL FROM` and `RCPT TO` commands. (issue #764)
* Added a work-around for IMAP servers that quote FLAGS responses. (issue #771)
* Optimized SmtpClient's logic for byte-stuffing the message when writing it to the socket during the `DATA` command.
* Added an `SslProtocols` property to IMailService (was already in MailService).
* Fixed the DIGEST-MD5 charset handling.
* Fixed a bug in the BodyPart.TryParse() method that could be used when serializing and deserializing FETCH'd responses from an IMAP server.
* Fixed BodyPartCollection.IndexOf().
* Fixed Envelope.ToString and TryParse() to properly deal with the rfc822 group address syntax.
* Fixed the ImapClient logic to properly handle parsing nested group addresses (not likely that anyone would hit this).
* Improved ImapClient's state tracking so that it is possible to re-connect the ImapClient in the Disconnected event handler. (issue #770)
* Fixed IMAP API's that take IList of UIDs or indexes to accept 0 UIDs/indexes.
* Fixed ImapClient's BODYSTRUCTURE parser to properly handle multiple body-extensions tokens.
* Fixed ImapClient to properly handle the `* PREAUTH` greeting when connecting to an IMAP server.

Note to users upgrading from MailKit 1.x:

In order to authenticate using the XOAUTH2 SASL mechanism, you must now use the following approach:

client.Authenticate (new SaslMechanismOAuth2 (username, auth_token));
