Release Notes

* Added a MessageSummary.Folder property and MessageThread.Message property to allow developers to thread messages from multiple IMAP folders and be able to figure out which folder each message belongs to.
* Added a work-around for IMAP servers that send a UIDNEXT response with a value of '0'. (issue #1010)
* Added an IMailFolder.Supports(FolderFeature) method so that developers can check whether a feature is supported by the folder without needing a reference to the corresponding ImapClient object in order to check the Capabilities.
* Fixed the HTTP proxy client to accept "200 OK" with an empty body as a successful connection. (issue #1015)
* Fixed the SOCKS5 proxy client to correctly send an authentication request. (issue #1019)
* Added support for customizable ProtocolLogger client/server prefixes. (issue #1024)
* Fixed an NRE in SslHandshakeException.Create() when running on Mono/Linux.
* Modified the SmtpClient to take advantage of the SMTPUTF8 extension for the `MAIL FROM` and `RCPT TO` commands even if a `options.International` is not explicitly set to `true` if any of the mailbox addresses are international addresses. (issue #1026)
* Added support for a new Important SpecialFolder (rfc8457).
* Added support for the IMAP REPLACE extension (rfc8508).
* NuGet packages now include the portable pdb's.

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));
