* Removed APIs marked as [Obsolete] in 2.x.
* Simplify Fetch()/FetchAsync() APIs by using a new IFetchRequest parameter instead. Made previous APIs into extension methods to aid in porting from 2.x.
* Replaced Add/Remove/SetFlags() APIs with Store()/StoreAsync() and simplified the APIs by using a new IStoreFlagsRequest parameter. Made previous APIs into extension methods to aid in porting from 2.x.
* Replaced Add/Remove/SetLabels() APIs with Store()/StoreAsync() and simplified the APIs by using a new IStoreLabelsRequest parameter. Made previous APIs into extension methods to aid in porting from 2.x.
* Simplify Append()/AppendAsync() APIs by using a new IAppendRequest parameter instead. Made previous APIs into extension methods to aid in porting from 2.x.
* Simplify Replace()/ReplaceAsync() APIs by using a new IReplaceRequest parameterinstead. Made previous APIs into extension methods to aid in porting from 2.x.
* Updated SmtpClient.Send()/SendAsync() methods to return a string. (issue #1161)
* Added support for the SCRAM-SHA*-PLUS SASL mechanisms. (issue #950)
* Added authzid support for SCRAM SASL mechanisms.
* Added support for the ANONYMOUS SASL mechanism.
* Added support for an HttpsProxyClient. (issue #1251)
* Added AcceptedKeywords and PermanentKeywords to IMailFolder. (issue #1256)
* Rewrote NTLM support based on official specs. Now supports channel-binding and using the default system credentials.
* Modified ImapFolder.Fetch(int, int, ...) to shortcut if ImapFolder.Count == 0.
* Updated SmtpClient to append an ORCPT arg to RCPT TO commands and to hex-encode the ENVID parameter value.
* Improved/simplified logic for ranking SASL authentication mechisms for each client.
* Added SaslMechanism.ChallengeAsync() to facilitate future SASL mechanisms that may need to make network requests such as Kerberos/GSSAPI and perhaps even future/custom OAuth2 implementations.
* Always set SearchResults.Count/Min/Max properties if we can.
* Throw TimeoutException is case of a network time out. (issue #1269)
* Fixed parsing of IMAP flag lists to handle lowercase flag names. (issue #1277)
* Use OrdinalIgnoreCase when comparing "EARLIER" atom token.
* Avoid unnecessary string copies. (issue #1292)
* Drop support for .NET 4.5 and replace it with .NET 4.5.2
* Simplified event emissions based on EXISTS and EXPUNGED notifications. A CountChanged event is now *always* emitted when the server sends an EXISTS notification.
