Release Notes

* Don't enable support for TLS v1.1 by default anymore. (issue #1077)
* Added support for the SCRAM-SHA-512 SASL mechanism. (issue #1097)
* Added support for the OAUTHBEARER SASL mechanism.
* Updated SSL certificate info for the common mail servers (GMail, outlook.com, Yahoo! Mail, etc).
* Improved the SslHandshakeException error message to report common mistakes like trying to initiate an SSL connection on a non-SSL port.
* Improved IMAP's "Unexpected token" exception messages a bit
* Updated code to use ArrayPools from System.Buffers.

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));
