Security related changes:
	Improved countermeasure against "Passive Analysis of SSH
	(Secure Shell) Traffic"
http://openwall.com/advisories/OW-003-ssh-traffic-analysis.txt


	The countermeasures introduced in earlier OpenSSH-2.5.x versions
	caused interoperability problems with some other implementations.

	Improved countermeasure against "SSH protocol 1.5 session
	key recovery vulnerability"
http://www.core-sdi.com/advisories/ssh1_sessionkey_recovery.htm


New options:
	permitopen authorized_keys option to restrict portforwarding.

	PreferredAuthentications allows client to specify the order in which
	authentication methods are tried.

Sftp:
	sftp client supports globbing (get *, put *).

	Support for sftp protocol v3 (draft-ietf-secsh-filexfer-01.txt).

	Batch file (-b) support for automated transfers

Performance:
	Speedup DH exchange. OpenSSH should now be significantly faster when
	connecting use SSH protocol 2.

	Preferred SSH protocol 2 cipher is AES with hmac-md5. AES offers
	much faster throughput in a well scrutinised cipher.

Bugfixes:
	stderr handling fixes in SSH protocol 2.

	Improved interoperability.

Client:
	The client no longer asks for the the passphrase if the key
	will not be accepted by the server (SSH2_MSG_USERAUTH_PK_OK)

Miscellaneous:
	scp should now work for files > 2GB

	ssh-keygen can now generate fingerprints in the "bubble babble"
	format for exchanging fingerprints with SSH.COM's SSH protocol 2
	implementation.

Preliminary patches for OpenBSD-2.6 are available on request.
