new features:
	integration of Wietse Venema's tcpwrapper library (libwrap)

	with "proxy" address, option "resolve" controls if hostname or IP
	address is sent in request

	option "lowport" establishes limited authorization for TCP and UDP
	connections 

solved problems and bugs:
	PROBLEM: socat daemon terminated when the address of a connecting
	client did not match range option value instead of continue listening
	SOLVED: in this case, print warning instead of error to keep daemon
	active 

	PROBLEM: tcp-listen with fork sometimes left excessive number of zombie
	processes
	SOLVED: dont assume that each exiting child process generates SIGCHLD

	when converting CRNL to CR, socat converted to NL


further corrections:
	configure script disables features that depend on missing files

	server.pem permissions corrected to 600

	improved .spec file (thanks to Gerd v. Egidy)

	"make install" now does not strip; use "make strip; make install"
	instead (suggested by Peter Bray)

####################### V 1.3.0.1:

solved problems and bugs:
	PROBLEM: OPENSSL did not apply tcp, ip, and socket options
	SOLVED: OPENSSL now correctly handles the options list

	PROBLEM: CRNL to NL and CRNL to CR conversions failed when CRNL crossed
	block boundary
	SOLVED: these conversions now simply strip all CR's or NL's from input
	stream 


porting:
	SunOS ptys now work on x86, too (thanks to Peter Bray)

	configure looks for freeware libs in /pkgs/lib/ (thanks to Peter Bray)


further corrections:
	added WITH_PROXY value to -V output

	added compile dependencies of WITH_PTY and WITH_PROXY

	-?? did not print option group of proxy options

	corrected syntax for bind option in docu

	corrected an issue with stdio in unidirectional mode

	options socksport and proxyport support service names

	ftp.sh script supports proxy address

	man page no longer installed with execute permissions (thanks to Peter
        Bray) 

	fixed a malloc call bug that could cause SIGSEGV or false "out of
	memory" errors on EXEC and SYSTEM, depending on program name length and
	libc.

####################### V 1.3.0.0:

new features:
	proxy connect with optional proxy authentication

	combined hex and text dump mode, credits to Gregory Margo

	address pty applies options user, group, and perm to device


solved problems and bugs:
	PROBLEM: option reuseport was not applied (BSD, AIX)
	SOLVED:	option reuseport now in phase PASTSOCKET instead of PREBIND,
		credits to Jean-Baptiste Marchand

	PROBLEM: ignoreeof with stdio was ignored
	SOLVED: ignoreeof now works correctly with address stdio

	PROBLEM: ftp.sh did not use user supplied password
	SOLVED: ftp.sh now correctly passes password from command line

	PROBLEM: server.pem had expired
	SOLVED: new server.pem valid for ten years

	PROBLEM: socks notice printed wrong port on some platforms
	SOLVED: socks now uses correct byte-order for port number in notice


further corrections:
	option name o_trunc corrected to o-trunc

	combined use of -u and -U is now detected and prevented

	made message system a little more robust against format string attacks


####################### V 1.2.0.0:

new features:
	address pty for putting socat behind a new pseudo terminal that may
	fake a serial line, modem etc.

	experimental openssl integration
	(it does not provide any trust between the peers because is does not
	 check certificates!)

	options flock-ex, flock-ex-nb, flock-sh, flock-sh-nb to control all
	locking mechanism provided by flock()

	options setsid and setpgid now available with all address types

	option ctty (controlling terminal) now available for all TERMIOS
	addresses 

	option truncate (a hybrid of open(.., O_TRUNC) and ftruncate()) is
	replaced by options o-trunc and ftruncate=offset

	option sourceport now available with TCP and UDP listen addresses to
	restrict incoming client connections

	unidirectional mode right-to-left (-U)


solved problems and bugs:
	PROBLEM: addresses without required parameters but an option containing
		a '/' were incorrectly interpreted as implicit GOPEN address
	SOLVED: if an address does not have ':' separator but contains '/',
		check if the slash is before the first ',' before assuming
		implicit GOPEN.


porting:
	ptys under SunOS work now due to use of stream options


further corrections:
	with -d -d -d -d -D, don't print debug info during file analysis


####################### V 1.1.0.1:

new features:
	.spec file for RPM generation


solved problems and bugs:
	PROBLEM: GOPEN on socket did not apply option unlink-late
	SOLUTION: GOPEN for socket now applies group NAMED, phase PASTOPEN
		options 

	PROBLEM: with unidirectional mode, an unnecessary close timeout was
		applied
	SOLUTION: in unidirectional mode, terminate without wait time

	PROBLEM: using GOPEN on a unix domain socket failed for datagram
		sockets
	SOLUTION: when connect() fails with EPROTOTYPE, use a datagram socket


further corrections:

	open() flag options had names starting with "o_", now corrected to "o-"

	in docu, *-listen addresses were called *_listen

	address unix now called unix-connect because it does not handle unix
	datagram sockets

	in test.sh, apply global command line options with all tests


####################### V 1.1.0.0:

new features:
	regular man page and html doc - thanks to kromJx for prototype

	new address type "readline", utilizing GNU readline and history libs

	address option "history-file" for readline

	new option "dash" to "exec" address that allows to start login shells

	syslog facility can be set per command line option

	new address option "tcp-quickack", found in Linux 2.4

	option -g prevents option group checking

	filan and procan can print usage

	procan prints rlimit infos


solved problems and bugs:
	PROBLEM: raw IP socket SIGSEGV'ed when it had been shut down.
	SOLVED: set eof flag of channel on shutdown.

	PROBLEM: if channel 2 uses a single non-socket FD in bidirectional mode
		and has data available while channel 1 reaches EOF, the data is
		lost. 
	SOLVED: during one loop run, first handle all data transfers and
		_afterwards_ handle EOF. 

	PROBLEM: despite to option NONBLOCK, the connect() call blocked
	SOLVED: option NONBLOCK is now applied in phase FD instead of LATE

	PROBLEM: UNLINK options issued error when file did not exist,
		terminating socat
	SOLVED: failure of unlink() is only warning if errno==ENOENT

	PROBLEM: TCP6-LISTEN required numeric port specification
	SOLVED: now uses common TCP service resolver

	PROBLEM: with PIPE, wrong FDs were shown for data transfer loop
	SOLVED: retrieval of FDs now pays respect to PIPE pecularities

	PROBLEM: using address EXEC against an address with IGNOREEOF, socat
		never terminated
	SOLVED: corrected EOF handling of sigchld


porting:
	MacOS and old AIX versions now have pty

	flock() now available on Linux (configure check was wrong)

	named pipe were generated using mknod(), which requires root under BSD
	now they are generated using mkfifo


further corrections:
	lots of address options that were "forgotten" at runtime are now
	available 

	option BINDTODEVICE now also called SO-BINDTODEVICE, IF

	"make install" now installs binaries with ownership 0:0


####################### V 1.0.4.2:

solved problems and bugs:
	PROBLEM: EOF of one stream caused close of other stream, giving it no
	chance to go down regularly
	SOLVED: EOF of one stream now causes shutdown of write part of other
	stream

	PROBLEM: sending mail via socks address to qmail showed that crlf
	option does not work
	SOLVED: socks address applies PH_LATE options

	PROBLEM: in debug mode, no info about socat and platform was issued
	SOLVED: print socat version and uname output in debug mode

	PROBLEM: invoking socat with -t and no following parameters caused
	SIGSEGV
	SOLVED: -t and -b now check next argv entry

	PROBLEM: when opening of logfile (-lf) failed, no error was reported
	and no further messages were printed
	SOLVED: check result of fopen and print error message if it failed

new features:
	address type UDP-LISTEN now supports option fork: it internally applies
	socket option SO_REUSEADDR so a new UDP socket can bind to port after
	`accepting a connection (child processes might live forever though)
	(suggestion from Damjan Lango)


####################### V 1.0.4.1:

solved problems and bugs:
	PROB: assert in libc caused an endless recursion
	SOLVED: no longer catch SIGABRT

	PROB: socat printed wrong verbose prefix for "right to left" packets
	SOLVED: new parameter for xiotransfer() passes correct prefix

new features:

porting:
	before Gethostbyname, invoke inet_aton for MacOSX


####################### V 1.0.3.0:

solved problems and bugs:

	PROB: test 9 of test.sh (echo via file) failed on some platforms,
	socat exited without error message
	SOLVED: _xioopen_named_early(): preset statbuf.st_mode with 0

	PROB: test 17 hung forever
	REASON: child death before select loop did not result in EOF
	SOLVED: check of existence of children before starting select loop

	PROB: test 17 failed
	REASON: child dead triggered EOF before last data was read
	SOLVED: after child death, read last data before setting EOF

	PROB: filan showed that exec processes incorrectly had fd3 open
	REASON: inherited open fd3 from main process
	SOLVED: set CLOEXEC flag on pty fd in main process

	PROB: help printed "undef" instead of group "FORK"
	SOLVED: added "FORK" to group name array

	PROB: fatal messages did not include severity classifier
