Release Notes

* Fixed trimming delimeters from the end of IMAP folder names.
* Fixed fetching of IMAP PreviewText when message bodies do not contain any text parts.
* Fixed Pop3Client to never emit Authenticated events w/ null messages.
* Dropped SslProtocols.Tls (aka TLSv1.0) from the default SslProtocols used by IMAP, POP3 and SMTP clients. To override this behavior, use the client.SslProtocols property to set the preferred SslProtocol(s).
* Fixed ImapFolder.Search(string query) to properly encode the query string when the query contains unicode characters.
* If an IMAP SEARCH fails due to BADCHARSET, retry the search query after flattening the query strings into US-ASCII. This *may* fix issues such as issue #808.
* Added work-arounds for Exchange IMAP bugs causing it to send mal-formed body-fld-dsp parameters. (issue #919)
* Go back to only using the BDAT command when the user is sending BINARYMIME in the SmtpClient. (issue #921)

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));
