* Fixed fetching of MessageSummaryItems.PreviewText if the octet count of the message body is 0. (issue #1430)
* Modified ImapFolder.Search(SearchOptions.None, query) work the same as ImapFolder.Search(query). (issue #1437)
* Improved performance of SmtpClient by reducing memory allocations and pipelining the DATA command when the PIPELINING extension is available.
* Refactored sync and async SmtpClient APIs such that the synchronous APIs no longer call methods marked with async in order to reduce AsyncMethodBuilder state machines/allocations.
* Modified SmtpClient to only send the ORCPT argument to RCPT TO if NOTIFY is specified.
* Improved performance of Pop3Client by reducing memory allocations.
* Refactored sync and async Pop3Client APIs such that the synchronous APIs no longer call methods marked with async in order to reduce AsyncMethodBuilder state machines/allocations.
* Improved IMAP's BODY/BODYSTRUCTURE parser to be able to scan ahead multiple tokens in order to better handle syntactically incorrect responses in a more graceful way. (issue #1446)
* Improved IMAP's ENVELOPE parser to handle ("Microsoft Exchange Server" NIL NIL ".MISSING-HOST-NAME.") in a more graceful way. (issue #1451)
