Release Notes

* Bumped the System.Net.Security dependency for security fixes (CVE-2017-0249).
* Reduced explicit nuget dependencies.
* Added a work-around for Microsoft Exchange IMAP servers that sometimes erroneously respond with unneeded continuation responses. (issue #852)
* Fixed the ImapClient to Stop looping over SASL mechanisms if the server disconnects us. (issue #851)
* Added support for HTTP proxies. (issue #847)
* Fixed IMAP to properly handle EXPUNGE notifications during a FETCH request. (issue #850)

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));
