2016.0.0-beta1

New Features:

* Added support for HMAC-SHA512 (hmac-sha2-512 and hmac-sha2-512-96)
* Added support for Universal Windows Platform 10 (UAP10.0)

Changes:

* Overall performance improvements
* Relicensed code under MIT license, explicitly permitting reuse within proprietary software
  provided all copies of the licensed software include a copy of the MIT License terms and the
  copyright notice
* Separated our hash algorithms into SshNet.Security.Cryptography project and package
* When available, prefer hash algorithms and encodings from target framework
* Refactoring to prepare for upcoming .NET Core support

Fixes:

* Partial reads from stream assume end (CodePlex issue #1516)
* Session.Disconnect() hangs forever (CodePlex issue #2591)

2014.4.6-beta2

New Features:

* Improved accuracy of IsConnected on .NET
* Added support for ssh.com (SSH-2) private keys (issue #1987)
* Support an acceptable group of up to 8192 bits for SHA-1 and SHA-256 Diffie-Hellman Group and Key Exchange (issues #1973 and #1777)

Changes:

* Reduced default buffer size for SftpClient from 64 KB to 32 KB as some SSH servers apply a hard limit of 64 KB at the transport level.

Fixes:

* SftpClient is throwing undocumented exceptions (issue #2148)
* Client channels are no longer closed on dispose (issue #1943)
* SftpClient.Exists(string) returns true for a path that does not exist (issues #1952, #1696 and #1574)

* Lines before protocol identification string are not skipped (issue #1935 and #2223)
* ShellStream.ReadLine produces incorrect output when reading multi-byte characters (issue #2190)
* SftpClient constructor throws ArgumentException when host contains underscore (issue #1845)
* Signing key is missing from source download (issue #2455)
* Forwarded Port channels can get stuck waiting (issue #1558)
* NullReferenceException when SftpFileStream is finalized after dispose of session (issue #2013)
* BlockCipher.Encrypt fails if input message is not padded (issue #2547)
* ScpClient: Missing files when using DirectoryUpload (issue #1382)
* Dynamic port forwarding slows down to a crawl (issue #2010)
* SendKeepAlive causes SocketException when connection is dropped (issue #2029)
* SocketException on Dispose or Disconnect (issue #2400)
* Sending EOF on wrong channel number (issue #1877)
* ForwardedPortDynamic: Unhandled exception if client terminates socket (issue #1844)

2014.4.6-beta1

New Features:

* Added callbacks to UploadFile, DownloadFile and ListDirectory in SftpClient (issue #1324)
* Allow a given private key file to be used concurrently
* Performance improvements:
    - optimization of payload size for both read and write operations (SftpClient only)
    - increase window size from 1MB to 2MB
    - increase buffer size from 16KB to 64KB for SftpClient
    - take into account the maximum remote packet size of the channel for write operations
    - increase maximum size of packets that we can receive from 32 KB to 64 KB
* Improve exception message for authentication failures

Breaking changes:

* Assembly name is now Renci.SshNet for all supported frameworks
* The Renci.SshNet assemblies for .NET and Silverlight are now strong-named (issue #1802)

Fixes:

* Incorrect copyright in assemblies (issue #1764)
* Remove linefeed from WriteLine method in Shellstream class (issue #1584)
* Disable logging of messages in release builds (issue #1767)

* No connection possible with the same auth method requested multiple times (issue #1930)
* Unobserved exception rethrown by finalizer thread (issue #1298 and #1587)
* Client cipher is used to decrypt server messages (issue #1917)
* Connection dropped by server due to invalid DSA signature (issue #1918)
* Correct casing of Security/Cryptography/HMAC.cs to fix build on Linux (issue #1505)
* HTTP proxy hangs (issue #1890)
* Wrong parameters to SetSocketOption leads to SocketException under Mono (issue #1799)
* Incorrect check for timeout values (issue #1620)
* Wrong PKCS7 padding in DES algorithm (issue #1580)
