<cote2004-github@yahoo.com>
- adjustments to documentation after move to github
- removal of old RCS/CVS tags since we have git
version 8.2.1 (Jun 2, 2015):
- added TCP keepalives between client and server - TCP-based consoles
already had the code - this was mostly an oversight
- patch for SEGV and task execution - patch by Artem Savkov
<asavkov@redhat.com>
- expanded break sequences from [1-9] to [1-9a-z] - based on patch by
Artem Savkov <asavkov@redhat.com>
version 8.2.0 (Apr 20, 2014):
- added --with-trust-uds-cred which uses getsockopt() to fetch and
trust the client uid, bypassing password lookups - patch by Anton
Lundin <glance@acc.umu.se>
- missing closedir() causing memory leak - patch by Anton Lundin
<glance@acc.umu.se>
- sending a break signal over IPMI was broken - based on patch by
Alexander Y. Fomichev <git.user@gmail.com>

untested (except by the author), there's a lack of documentation, and
I'm hoping for non-getifaddrs() system support) - patch by Milos
Vyletel <milos.vyletel@gmail.com>
- no more K&R compiler support

Zonker <consoleteam@gmail.com>

- deprecated --with-cycladests (noop now) - cross-compilation should
work without it as autologin now expects setpgrp() to take two
arugments instead of testing for it
- no automatic checks for an empty password when using PAM
authentication - based on discussion with Ryan Kirkpatrick
<linux@rkirkpat.net>
- added 'sslcacertificatefile' and 'sslcacertificatepath' client
configuration options - based on patch by Aki Tuomi <cmouse@cmouse.fi>

configuration options
- added --with-req-server-cert to force clients to require a certificate
from the server when using SSL - based on emails with Thor Simon
<tls@coyotepoint.com>
- added server-side tasks (see conserver.cf man page) that are invoked
by the client (useful for things like IPMI-based power control of
servers, invoking resets of terminal server ports, or anything else
that requires scripting) - ideas from patch by Anton Lundin
<glance@acc.umu.se> and discussion on mailing list (2011)
- added 'confirm' option to break sequences
- added 'breaklist' option to limit exposure of break sequences to

version 7.2.5 (Jan 27, 2003):
- fixed many documentation bugs - reported by Dave Stuit
<djs@tellme.com>
- added -I option to client which operates like -i, but on the
primary conserver only - suggested by Dave Stuit

Dave Stuit <djs@gnac.com>
- gethostbyname() failure for a console now doesn't cause a
shutdown - reported by Todd Stansell <todd@stansell.org>

line length limitations, they now support comments (`#' lines),
and lines with leading whitespace are continuations of
previous lines

Stansell <todd@stansell.org>
version 7.1.0 (Jul 26, 2001):

- Fixed 'make install' problem under MacOS X and cygwin
- Client -l option totally broken in 7.0.3 - patch by Daniel E.
Singer <des@cs.duke.edu>
- Client now accepts IP addresses from server and server now sends
the IP of the socket instead of its hostname to the client,
fixing part of the multi-interface problem

to give the terminal server a chance to clean up

opposite of the old -n flag, which now does nothing
- Added -7 flag to client and server for stripping the high bit
of data on either side (--disable-8bit removed)
- Added -b to server to specify the base port number for the
secondary communication channel - based on code from Enrik
Berkhan <Enrik.Berkhan@planb.de>
- Changed -d and -D flags to -r and -R in client - now -D enables
debugging mode in the client (and -d is unused)
- Changed -r to -G in client so -r could be used for the above
- Client now uses getpassphrase() (if available) for > 8 char
passwords - pointed out by Gregory Bond <gnb@itga.com.au>
- Improved signal handling
- Improved process handling (POSIX waitpid() now necessary)
- Significant rework of STREAMS-based pseudo-tty code
- TCP connections ('!' config syntax) now have some Telnet protocol
knowledge, removing the "noise" seen when connecting to a terminal
server - reported by Todd Stansell <todd@stansell.org>

- Client and server both run in Windows (tested with Windows
2000) under the cygwin environment thanks to a debug-fest with
Emmett Hogan <hogan@gnac.com>
- Using autoconf version 2.50
- Man pages reworked and conserver.passwd page created by Dave
Stuit <djs@gnac.com> - the pain he suffered documenting
the program (and pointing out many of the bugs fixed above)
should help endless others

- Added -M to server to specify the address to listen on
based on code from Enrik Berkhan <Enrik.Berkhan@planb.de>
- Added -p option to client and server to specify the port to
connect to and listen on (--with-port still sets the default)
- Added logfile output when going into daemon mode
