Release Notes

* Fixed ImapUtils.GetUniqueHeaders() to accept all valid header field name characters. (issue #806)
* Catch all exceptions thrown in IdleComplete(). (issue #825)
* Improved cancellability of IMAP, POP3 and SMTP clients when sending commands to the server. (issue #827)
* Break apart IMAP commands with really long uid-sets. (issue #834)
* Rewrote Connect logic to use Socket.Connect (IPAddress, int) instead of Connect (string, int) in an attempt to fix https://stackoverflow.com/q/55382267/87117
* Fixed SmtpStream.ReadAheadAsync() to preserve remaining input. (issue #842)

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));
