Release Notes

* Optimized MailKit's logic for breaking apart long IMAP commands for GMail, Dovecot, and Yahoo! Mail.
* Fixed the IMAP stream tokenizer to properly handle UTF8 atom tokens. (issue #859)
* Fixed IMAP search code to always handle untagged SEARCH responses even when the response SHOULD be an untagged ESEARCH response. (issue #863)
* Replaced SearchQuery.SentAfter with SentSince to be more consistent with IMAP terminology.

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));
