* Handle BAD responses to the NAMESPACE command for Exchange. (issue #1135)
* Added support for configuring SSL/TLS cipher algorithms (only available in the .NET 5.0 API). (issue #1140)
* Updated GMail and Yahoo! Mail SSL certificate info.
* Protect against NREs in NTLM authentication of no OSVersion is set. (issue #1148)
* Added work-around for hMailServer bug that doesn't accept seq-ranges in descending order. (issue #1150)
* Properly escape IPv6 addresses for Uri in order to allow Connect/Async methods to work with IPv6 addresses. (issue #1165)
* Added IsEncrypted and IsSigned properties to IMailService. (issue #1175)

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));
