0.45 - Mon March 7 2005

- Makefile no longer appends 'static' to statically linked binaries

- Add optional SSH_ASKPASS support to the client

- Respect HOST_LOOKUP option

- Fix accidentally removed "return;" statement which was removed in 0.44
  (causing clients which sent an empty terminal-modes string to fail to
  connect - including pssh, ssh.com, danger hiptop). (patches
  independently from Paul Fox, David Horwitt and Sven-Ola Tuecke)

- Read "y/n" response for fingerprints from /dev/tty directly so that dbclient
  will work with scp.

0.44 - Mon Jan 3 2005

- SECURITY: Fix for PAM auth so that usernames are logged and conversation
  function responses are allocated correctly - all 0.44test4 users with PAM
  compiled in (not default) are advised to upgrade.

- Fix calls to getnameinfo() for compatibility with Solaris

- Pristine compilation works (run 'configure' from a fresh dir and make it
  there)

- Fixes for compiling with most options disabled.

- Upgraded to LibTomCrypt 0.99 and LibTomMath 0.32

- Make sure that zeroing out of values in LTM and LTC won't get optimised away

- Removed unused functions from loginrec.c

- /dev/random is now the default entropy source rather than /dev/urandom

- Logging of IPs in auth success/failure messages for improved greppability

- Fix dbclient so that "scp -i keyfile" works. (It can handle "-ikeyfile
  properly)

- Avoid a race in server shell-handling code which prevents the exit-code
  from being returned to the client in some circumstances.

- Makefile modified so that install target works correctly (doesn't try
  to install "all" binary) - patch from Juergen Daubert

- Various minor fixes and compile warnings.

0.44test4 - Tue Sept 14 2004 21:15:54 +0800

- Fix inetd mode so it actually loads the hostkeys (oops)

- Changed DROPBEAR_DEFPORT properly everywhere

- Fix a small memory leak in the auth code

- WCOREDUMP is only used on systems which support it (ie not cygwin or AIX)

- Check (and fail for) cases when we can't negotiate algorithms with the
  remote side successfully (rather than bombing out ungracefully)

- Handle authorized_keys files without a terminating newline

- Fiddle the channel receive window size for possibly better performance

- Added in the PAM authentication code (finally! thanks to Martin Carlsson)

0.44test3 - Fri Aug 27 22:20:54 +0800

- Fixed a bunch of warnings.

- scp works correctly when passed a username (fix for the dbclient program
  itself as well, "-lmatt" works as well as "-l matt").

- Remove unrequired debian files

- Exit with the remote process's return code for dbclient

- Display stderr messages from the server in the client

- Add circular buffering to the channel code. This should dramatically reduce
  the amount of backtraffic sent in response to traffic incoming to the
  Dropbear end - improves high-latency performance (ie dialup).

- Various other related channel-handling fixups.

- Allow leading lines in the banner when connecting to servers

- Fixed printing out errors onto the network socket with stderr (for inetd
  mode when using xinetd)

- Remove obselete documentation

- Fix a null-pointer exception when trying to free non-existant listeners
  at cleanup.

- DEBUG_TRACE now only works if you add "-v" to the program commandline

- Don't leave stdin non-blocking on exit - this caused the parent shell
  of dbclient to close when dbclient exited, for some shells in BusyBox

- Server connections no longer timeout after 5 minutes

- Fixed stupid DSS hostkey typo (server couldn't load host keys)

0.44test2 - Tues Aug 17 2004 17:43:54 +0800

- Fix up dropbearmulti targets in the Makefile - symlinks are now created

- Compile fake-rfc2553 even with dropbearconvert/dropbearkey - this 
  allows them to work on platforms without a native getaddrinfo()

- Create ~/.ssh/known_hosts properly if it doesn't exist

- Fix basename() function prototype

- Backport some local changes (more #ifdefs for termcodes.c, a fix for missing
  defines on AIX).

- Let dbclient be run as "ssh"

- Initialise mp_ints by default

0.44test1 - Sun Aug 16 2005 17:43:54 +0800

- TESTING RELEASE - this is the first public release of the client codebase,
  so there are sure to be bugs to be found. In addition, if you're just using
  the server portion, the final binary size probably will increase - I'll
  be trying to get it back down in future releases.

- Dropbear client added - lots of changes to the server code as well to 
  generalise things

- IPv6 support added for client, server, and forwarding

- New makefile with more generic support for multiple-program binaries

0.43 - Fri Jul 16 2004 17:44:54 +0800

- SECURITY: Don't try to free() uninitialised variables in DSS verification
  code. Thanks to Arne Bernin for pointing out this bug. This is possibly
  exploitable, all users with DSS and pubkey-auth compiled in are advised to
  upgrade.

- Clean up agent forwarding socket files correctly, patch from Gerrit Pape.

- Don't go into an infinite loop when portforwarding to servers which don't
  send any initial data/banner. Patch from Nikola Vladov

- Fix for network vs. host byte order in logging remote TCP ports, also
  from Gerrit Pape.

- Initialise many pointers to NULL, for general safety. Also checked cleanup
  code for mp_ints (related to security issues above).

0.42 - Wed Jun 16 2004 12:44:54 +0800

- Updated to Gerrit Pape's official Debian subdirectory

- Fixed bad check when opening /dev/urandom - thanks to Danny Sung.

- Added -i inetd mode flag, and associated options in options.h . Dropbear
  can be compiled with either normal mode, inetd, or both modes. Thanks
  to Gerrit Pape for basic patch and motivation.

- Use <dirent.h> rather than <sys/dir.h> for POSIX compliance. Thanks to Bill
  Sommerfield.

- Fixed a TCP forwarding (client-local, -L style) bug which caused the whole
  session to close if the TCP connection failed. Thanks to Andrew Braund for
  reporting it and helping track it down.

- Re-enable sigpipe for child processes. Thanks to Gerrit Pape for some
  suggestions, and BSD manpages for a clearer explanation of the behaviour.

- Added manpages, thanks to Gerrit Pape.

- Changed license text for LibTomCrypt and LibTomMath.

- Added strip-static target

- Fixed a bug in agent-forwarding cleanup handler - would segfault
  (dereferencing a null pointer) if agent forwarding had failed.

- Fix behaviour of authorized_keys parsing, so larger (>1024 bit) DSA keys will
  work. Thanks to Dr. Markus Waldeck for the report. 

- Fixed local port forwarding code so that the "-j" option will make forwarding
  attempts fail more gracefully.

- Allow repeated requests in a single session if previous ones fail - this fixes  PuTTY and some other SCP clients, which try SFTP, then fall-back to SCP if it
  isn't available. Thanks to Stirling Westrup for the report.

- Updated to LibTomCrypt 0.96 and LibTomMath 0.30. The AES code now uses
  smaller non-precomputed tables if DROPBEAR_SMALL_CODE is defined in
  options.h, leading to a significant reduction in the binary size.

0.41 - Mon Jan 19 2004 22:40:19 +0800

- Fix in configure so that cross-compiling works, thanks to numerous people for
  reporting and testing

- Terminal mode parsing now handles empty terminal mode strings (sent by
  Windows ssh.com clients), thanks to Ricardo Derbes for the report

- Handling is improved for users with no shell specified in /etc/passwd,
  thanks again to Ricardo Derbes

- Fix for compiling with --disable-syslog, thanks to gordonfh

- Various minor fixes allow scp to work with irix, thanks to Paul Marinceu for
  fixing it up

- Use <stropts.h> not <sys/stropts.h>, since the former seems more common

0.40 - Tue Jan 13 2004 21:05:19 +0800

- Remote TCP forwarding (-R) style implemented

- Local and remote TCP forwarding can each be disabled at runtime (-k and -j
  switches)

  people for reporting and testing fixes, including (in random order) Cristian
  Ionescu-Idbohrn, James Ewing, Steve Dover, Thomas Lundquist and Frederic
  Lavernhe

- Improved portability for IRIX, thanks to Paul Marinceu

- AIX and HPUX portability fixes, thanks to Darren Tucker for patches

  (also thanks to Mihnea Stoenescu)

- Various makefile improvements for cross-compiling, thanks to Friedrich
  Lobenstock and Mihnea Stoenescu

- Use daemon() function if available (or our own copy) rather than separate
  code (thanks to Frédéric Lavernhe for the report and debugging, and Bernard
  Blackham for his suggestion on what to look at)

- Fixed up support for first_kex_packet_follows, required to talk to ssh.com
  clients. Thanks to Marian Stagarescu for the bug report.

- Avoid using MAXPATHLEN, pointer from Ian Morris

- Improved input sanity checking

0.38 - Sat Oct 11 2003 16:28:13 +0800

- Default hostkey path changed to /etc/dropbear/dropbear_{rsa,dss}_host_key
  rather than /etc/dropbear_{rsa,dss}_host_key

- Added SMALL and MULTI text files which have info on compiling for multiple
  binaries or small binaries

- Allow for commandline definition of some options.h settings
  (without warnings)

- Be more careful handling EINTR

- More fixes for channel closing

- Added multi-binary support

- Improved logging of IPs, now get logged in all cases

- Don't chew cpu when waiting for version identification string, also
  make sure that we kick off people if they don't auth within 5 minutes.

  Trent Lloyd <lathiat at sixlabs.org> and
  Zach White <zwhite at darkstar.frop.org>

- Added some small changes so it'll work with AIX (plus Linux Affinity).
  Thanks to Shig for them.

- Improved the closing messages, so a clean exit is "Exited normally"

- Added some more robust integer/size checking in buffer.c as a backstop for
  integer overflows

- X11 forwarding fixed for OSX, path for xauth changed to /usr/X11R6/bin/xauth

- Channel code handles closing more nicely, doesn't sit waiting for an extra
  keystroke on BSD/OSX platforms, and data is flushed fully before closing
  child processes (thanks to 
  Cristian Ionescu-Idbohrn <cristian.ionescu-idbohrn at axis.com> for
  pointing that out).

- Changed "DISABLE_TCPFWD" to "ENABLE_TCPFWD" (and for x11/auth) so
  "disable DISABLE_TCPWD" isn't so confusing.

- Fix authorized_keys handling (don't crash on too-long keys, and
  use fgetc not getc to avoid strange macro-related issues), thanks to
  Cristian Ionescu-Idbohrn <cristian.ionescu-idbohrn at axis.com> 
  and Steve Rodgers <hwstar at cox.net> for reporting and testing.

0.34 - Fri August 15 2003 15:10:00 +0800

- Made syslog optional, both at compile time and as a compile option
  (suggested by Laurent Bercot <ska at skarnet.org>)
