2015-04-15 Version 2015 R3.1 #
(build number 5584)
This release disables "arcfour" cipher in SSH client core. Unless you are running FTP, IMAP, POP3 or SMTP
over an SSH channel, there is no need to upgrade.
Complete list of changes of version 2015 R3.1

2015-04-08 Version 2015 R3 #
(build number 5577)
Disabled RC4 in TLS/SSL
The security of RC4 symmetric encryption algorithm has been questionable for many years.
Recently, researchers have been able to exploit RC4's invariance weakness vulnerability
to retrieve about 64 bytes of encrypted information of a very small fraction of TLS/SSL connections that happen to use weak keys.
Since RC4 is no longer believed to be secure, it has been disabled by default.
Complete list of changes of version 2015 R3

2012-11-01 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 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

2012-03-05 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.
New multi-file methods in Rebex SFTP and FTP/SSL
FTP/SSL and SFTP got several new methods: Upload, Download, Delete and GetItems.
The first two are replacements for PutFiles/GetFiles (and support move operation in addition to copy),
Delete makes it possible to delete multiple files (or even a directory tree) at once
and GetItems makes it possible to retrieve a list of files for the whole directory tree in one call.
Common API for SFTP and FTP/SSL (experimental)
Lot of our customers have been asking for a common API capable of both SFTP and FTP/SSL.
Even though Ftp and Sftp objects provide a very similar API, they are still two distinct classes and writing code that can use either of them was hard.
Now, it got much better with the introduction of IFtp interface.
