Release Notes

* Fixed IMAP GetFolder() methods to match LIST responses case-insensitively. (issue 803)
* Added a work-around to SmtpClient for a .NET 4.5.2 bug on Windows 7 SP1. (issue 814)
* Added DeliveryStatusNotificationType and a property to SmtpClient to allow developers to specify the `RET` parameter value to the `MAIL FROM` command.
* Fixed a number of locations in the code to clear password buffers after using them.
* SmtpClient.Send[Async]() methods that accept a FormatOptions argument will no longer hide Bcc, Resent-Bcc, nor Content-Length headers when uploading the raw message to the SMTP server. It is now up to callers to add these values to their custom FormatOptions.HiddenHeaders property. (issue 360)

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));
