* Refactored Connect/ConnectAsync() logic to set timeouts *before* calling SslStream.AuthenticateAsClient() when connecting to an SSL-wrapped service. (issue #1059)
* Hardcode the value of SslProtocols.Tls13 for frameworks that do not support it and add it to the client's default SslProtocols. This adds TLS v1.3 support, by default, for apps using .NETStandard2.0 where the app project is built against a version of .NETCore that supports TLS v1.3. (issue #1058)
* Initialize IMAP SearchResults with the UIDVALIDITY value. (issue #1060)
* Make sure the ImapStream is not null (can be null if user calls Disconnect() causing IDLE to abort). (issue #1025)
* Case-insenitively match IMAP folder attribute flags (e.g. \HasNoChildren and \NoSelect).
* Added support for the IMAP SAVEDATE extension.
* Added support for detecting SMTP's REQUIRETLS extension.

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));
