1.0.0 99/03/12	Initial Release

1.0.1 99/03/17  Minor configuration changes to enable build on various
		distributions

1.0.2 99/03/29	new 'linktest' option for dialup systems
		(request by andreas@mtg.co.at)

		new 'oobfix' option (workaround for linux kernels
		< 2.0.36 which do have an out of band data
		processing bug, this is required for the linktest
		option)

		new 'peerroute' option for dialup systems
		(request by xml@mailandnews.com)

		routing code fixes (thanks to xml@mailandnews.com)

1.0.3 99/04/06	new 'suspend', 'rxmax' and 'txmax' options

		dynamic IP client sample configuration

		minor code fixes for 'linktest' option

1.0.4 99/04/15	fixed slip mode selection bug, users are adviced
		to upgrade immediately to ensure proper slip
		mode selection!

		fixed 'public domain' definition in file headers
		and readme (the web site did already make clear
		that the Wassenaar treaty sense was meant)

		vpnd now uses Unix98 pty/ttys if available
		(kernel must be compiled with CONFIG_UNIX98_PTYS
		and CONFIG_DEVPTS_FS, devpts must be mounted
		using 'mount -t devpts devpts /dev/pts'), note
		that you do NOT need glibc 2.1 to use Unix98 PTYs.
		Unix98 PTYs do increase security somewhat so
		please enable use if possible!

		fixed little/big endian problem (thanks to 
		r.c.m.derooij@twi.tudelft.nl), this will break
		things on all big endian systems (e.g. Sparc)!
		users of big endian systems please upgrade
		immediately!

		new 'linkup', 'linkdown' and 'ipopts' options

		blowfish routines now available as optimized
		assembler for Intel x86 (486 or later), users
		of Intel 486 or later systems are adviced to
		upgrade to this version for increased
		performance and reduced system load

1.0.5 99/05/17	new 'sendbuf' and 'connwait' options, see
		vpnd.conf for details

		fixed minor bug in configure script

		split vpnd.c into multiple sources for more
		modularity and easier porting

		more optimized assembler for Intel x86
		(486 or later), all core crypto functions
		are now implemented as optimized assembler

		new extended master key file format including
		extended session setup, please see the README
		file or use 'vpnd -h' for details

		fixed minor bug in slip interface termination
		code (bug had no effect on Linux but may affect
		ports to other operating systems)

		added missing checksum verification in datarecv
		routine (very minor fix, any error was detected
		anyway during next transmission)

		fixed bug related to keyttl, key replacement
		didn't take place when ttl expired but when
		ttl expired and new data should be sent from
		server to client, this bug is minor as it
		just delays key replacement when connection
		is anyway idle

		added missing client sanity reset of keyttl,
		using keyttl in client configuration otherwise
		may cause unexpected behaviour

		added optional user password for new
		extended master key file, use 'vpnd -h'
		or see README file for details

		various additions to the README file

		major code rework to reduce use of global
		variables in preparation for later key
		management (will use posix threads)

		lots of code optimizations

1.0.6 99/06/07	added detection for -fno-inline as this switch
		caused compilation on some systems to fail

		added dynamic calculation of structure offsets
		for cryptox86.s as there's differences between
		between libc5 and glibc based systems

		fixed some minor compiler warnings reported

1.0.7 99/07/04	fixed a function call missing a variable when
		compiling without compression library

		new 'hmac' option for HMAC authentication
		(HMAC-MD5, HMAC-SHA1 or HMAC-RIPEMD160)
		instead of fast checksum, see vpnd.conf for
		details

		performance tuning of fast checksum generation

		new 'slipup' and 'slipdown' options, see vpnd.conf
		for details

		lock file handling for serial line device file
		based on the code from prandini@spe.it

		fixed minor compression detection bug in the x86
		assembler code (bug could actually never occur)

		data transmission modified for better performance
		over TCP connections.

1.0.8 99/07/31	missing definition of 'globals' in offsets.c
		fixed

		missing error case close() in crypto.c fixed

		added missing multi daemon info to vpnd.conf

		blowfish/md5/sha1/rmd160 speed improvements,
		see updated SPEED.TXT file

		fixed bug that zero key size required key file

		new -l command line parameter to allow the
		use of host names instead of IPs

1.1.0 99/11/19	fixed dns-ip conversion in tcp.c

		fixed missing newline in debug help info

		added new 'facility' option for syslog
		facility selection

		added syslog startup message with version
		number and compression info

		added compression info to -h command line
		argument

		changed configure script to warn if vpnd is
		built without compression

		fixed error message for incorrect file
		permissions

		fixed keyfile creation info message

		port to FreeBSD 3.3
