News for the 2.0.2 release

	Fixed a couple of problems in lshd, where the server process
	leaks file descriptors to user shells that it starts. These
	bugs implied a local denial of service hole, at best.

	Support for aes256-ctr.

	Newer nettle library. Bugfixes and performance improvements
	for the assembler code, in particular support for sparc64, and
	Makefile fixes.

News for the 2.0.1 release

	Fixed denial of service bug in lshd.

	Fixed a bug in lsh-make-seed, which could make the program go
	into an infinite loop on read errors.

	lsh now asks for passwords also in quite (-q) mode, as
	described in the manual.

	Control character filtering used to sometimes consider newline
	as a dangerous control character. Now newlines should be
	displayed normally.

	Removed support for the non-standard alias
	"diffie-hellman-group2-sha1". The standardized name is for
	this key exchange method is "diffie-hellman-group14-sha1".

	Several programs have new default behaviour:

	* lshd enables X11 forwarding by default (lsh still does not).

	* lsh-keygen generates RSA rather than DSA keys by default.

	* lsh-writekey encrypts the private key by default, using

	command line option. Supports both SOCKS-4 and SOCKS-5.

	The lsh client no longer sets its stdio file descriptors into
	non-blocking mode, which should avoid a bunch of problems. As
	a consequence, the --cvs-workaround command line option has
	been deleted.

	In the user lookup code, lshd now ignores the shadow database
	if getspnam returns NULL.

	In the server pty setup code, use the group "system" as a
	fallback if the group "tty" doesn't exist. This is the case on
	AIX. (There are however more problems on AIX, which makes it
	uncertain that lshd will work out of the box).

	Deleted the --ssh1-fallback option for lshd. I hope ssh1 is
	dead by now; if it isn't, you have to run ssh1d and lshd on
	different ports.
	
	Deleted code for bug-compatibility with ancient versions of
	Datafellow's SSH2. There are zero bug-compatibility hacks in
	this version.

News for the 1.5.4 release

	Added logging of tcpip-forward requests.

	Includes nettle-1.9, which have had some portability fixes and
	optimizations. In particular, arcfour on x86 should be much
	faster.
	
	Implemented flow control on the raw ssh connection. Enforce
	limits on the amount of buffered data waiting to be written to
	the socket.

	Moved all destructive string operations to a separate file
	lsh_string.c, which has exclusive rights of accessing string
	internals. Should make the code more robust, as buffer size
	and index calculations elsewhere in the code should hit an
	assert in lsh_string.c before doing damage.

	Some general simplification and cleanup of the code.

	lshd now has an experimental mode similar to telnet, where it
	accepts the 'none' authentication method and automatically
	disables services such as X and TCP forwarding. This can be
	useful in environment where it's required that /bin/login or
	some other program handle authentication and session setup
	(e.g. handle security contexts and so on).

News for the 1.4.2 release

	Fixed minor bug in bubble-babble key display.

	Fixed support for encrypted private keys.

	Tweaks to the handling of disabled accounts, and shadow
	passwords.

	  * Shadow records are looked up only if there's a single "x"
	    in the passwd entry.

	  * A passwd entry with a single "*" is interpreted as an
	    account that is open but with ordinary password
	    authentication disabled.

	  * A passwd entry that starts with "*" but is longer than one
            character is interpreted as a disabled account.

	  * It is recommended that all disabled accounts have their
            login shells set to something harmless, e.g. /bin/false.

	Disabled the "I/O error" message that was printed to the
	server log every time a session logged out.

	Other minor bug fixes.

     (lambda (backend)

	The sexptest program has been renamed to sexp_conv. It reads
	an sexp (for now, only canonical and transport syntax are
	supported) on stdin, and prints it using advanced, transport
	or canonical syntax. More features could be added.

	The --debug option now dumps both sent and received packets,
	and it includes a human readable name of the packet type.
	Packets of type SSH_MSG_USERAUTH_REQUEST are suppressed,
	however, because they typically contains user passwords.

	There is one known bug: Running without pty allocation (lsh
	-nt) doesn't work, at least not for me.
