which poses a problem for legacy .NET Compact Framework platforms based on editions
of Windows CE with no native SHA-2 support. To make solutions for these platforms compatible
with current TLS/SSL and SSH serves, we added a custom implementation of SHA-2 for these

Official support for Mono
All Rebex components now officially support Mono, an open source, cross-platform, implementation
of C# and the CLR that is binary compatible with Microsoft.NET. The same assemblies that work
on Windows now work on Mono in Linux or Apple's OS X as well.
Enhanced Outlook .MSG and winmail.dat/TNEF parsers
We have made numerous enhancements in
MailMessage object to make it even more compatible
with non-MIME message formats such as Outlook .MSG or winmail.dat/TNEF. The integrated RTF parser
and RTF to HTML converter has been improved as well.

2012-11-12 Version 2012 R3 #
(build number 4700)
Official support for Visual Studio 2012
All Rebex components now ship with full support for Microsoft Visual Studio 2012.
Samples and tutorials were updated for a new project file format.
Older Visual Studio and .NET Framework versions are still supported too.
Task-based asynchronous methods
The major change is the addition of new Task-based asynchronous methods to .NET 4.0/4.5 variant of our components.
This brings our API up-to-date with the current trends and makes it possible to utilize the new await keyword available in .NET 4.5 and Visual Studio 2012.
Finally, asynchronous programming became easy and seamless.
Check out some of the updated samples to see this in action!
Events now using SynchronizationContext
Previously, events raised by asynchronous methods were running in a background thread, making them hard to use in GUI applications.
Now, events are raised using the SynchronizationContext captured when the asynchronous method was started,
which basically means the events will run on application's GUI thread, making it possible to update application's controls directly from the event code.
Simplified Connect methods
We simplified even the most common task - connecting to a server. All you have to supply to the Connect method of Ftp, Imap, Pop3 or Smtp object is the server hostname and an SslMode.
The Connect method automatically chooses the port according to the communication protocol and the specified SSL mode.
Simplified custom certificate validation
We added a new ValidatingCertificate event to Ftp, Imap, Pop3 and Smtp.
It makes it much easier to write custom certificate validation routines - all you have to do is add an event handler which either calls

2012-06-11 Version 2012 R2 #
(build number 4546)
RTF to HTML converter
Almost all e-mail messages use HTML and/or plain text for the message body.
But this is not always the case for Outlook .MSG messages and even for mail messages using the infamous winmail.dat/TNEF format.
Both of these often use RTF instead of HTML, causing interoperability issues with third-party clients.
Fortunately, Rebex Secure Mail users no longer have to suffer from this - we have added a RTF-to-HTML converter that converts the body of these messages into HTML, which means they can be then processed just like an ordinary e-mail!

2012-03-01 Version 2012 R1 #
(build number 4444)
Components DLLs have been renamed
We found out that the DLL naming scheme we decided to use back in 2003 was no longer sustainable and decided to change it.
we now have
Most of the other DLLs were renamed as well during the process (
Rebex.Ftp.dll, for example).
We are sorry for any inconvenience this may have caused, but an alternative solution - introduction of a new DLL for shared functionality - would not be hassle-free either.
Fortunately, in order to upgrade to the new version, most customers will only need to remove references to the old DLLs and add references to the new ones because the API is still backward-compatible.
Compatibility enhancements in Rebex Secure Mail
We are constantly improving our mail writers and parsers to be as compatible with third-party software as possible.
In this version, we added support for some embedded OLE objects in TNEF/winmail.dat e-mails (they are parsed as attachments)
and enhanced our PKCS #7 (S/MIME) writer which used to have some compatibility issues with Entrust CSP.
