COPSSH - A yet another SSH Server & Client for Windows
Version 4.2.0 - October 2011
CHANGES FROM VERSION 4.1.0
1. UPDATED - OpenSSH 5.9p1
* Introduce sandboxing of the pre-auth privsep child using an optional sshd_config(5) "UsePrivilegeSeparation=sandbox" mode that enables mandatory restrictions on the syscalls the privsep child can perform. This intention is to prevent a compromised privsep child from being used to attack other hosts (by opening sockets and proxying) or probing local kernel attack surface.
* Add new SHA256-based HMAC transport integrity modes from http://www.ietf.org/id/draft-dbider-sha2-mac-for-ssh-02.txt These modes are hmac-sha2-256, hmac-sha2-256-96, hmac-sha2-512, and hmac-sha2-512-96, and are available by default in ssh(1) and sshd(8)

* Avoid endless blocking behaviour in mq_timedsend and mq_timedreceive when used with O_NONBLOCK message queues.
* Fix a problem to fetch correct file permissions on just created files on XP and Server 2003. * Avoid potential data loss when sending lots of data through a pipe
