* Don't use PublicSign on non-Windows NT machines when building.
* Work-around broken BODYSTRUCTUREs with `()` as a message/rfc822 body token. (issue #944)
* Added work-around for an Exchange bug that forgets to quote folder names containing tabs. (issue #945)
* Moved the SmtpDataFilter into the public API and updated the FAQ to show how to use it when writing messages into an IIS "pickup directory". (issue #948)

API Changes Since 2.0.x:

* Obsoleted SearchQuery.HasCustomFlags() and SearchQuery.DoesNotHaveCustomFlags(). These are now SearchQuery.HasKeywords() and SearchQuery.NotKeywords(), respectively.
* Obsoleted SearchQuery.DoesNotHaveFlags() in favor of SearchQuery.NotFlags().
* Obsoleted the IMessageSummary.UserFlags property in favor of IMessageSummary.Keywords.
* Obsoleted the MessageFlagsChangedEventArgs.UserFlags property in favor of MessageFlagsChangedEventArgs.Keywords.
* All IMailFolder.Fetch and IMailFolder.FetchAsync methods that took a HashSet<string> userFlags argument now take an IEnumerable<string> keywords argument. Note: this only affects you if your code used named method parameters (e.g. userFlags: myUserFlags).

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));
