+0.47 - Thurs Dec 8 2005
+- SECURITY: fix for buffer allocation error in server code, could potentially
+allow authenticated users to gain elevated privileges. All multi-user systems
+running the server should upgrade (or apply the patch available on the
+Dropbear webpage).
+- Fix channel handling code so that redirecting to /dev/null doesn't use
+100% CPU.
+- Turn on zlib compression for dbclient.
+- Set "low delay" TOS bit, can significantly improve interactivity
+over some links.
+- Added client keyboard-interactive mode support, allows operation with
+newer OpenSSH servers in default config.
+- Log when pubkey auth fails because of bad ~/.ssh/authorized_keys permissions
+- Improve logging of assertions
+- Added aes-256 cipher and sha1-96 hmac.
+- Fix twofish so that it actually works.
+- Improve PAM prompt comparison.
+- Added -g (dbclient) and -a (dropbear server) options to allow
+connections to listening forwarded ports from remote machines.
+- Various other minor fixes
+- Compile fixes for glibc 2.1 (ss_family vs __ss_family) and NetBSD
+(netinet/in_systm.h needs to be included).
+0.46 - Sat July 9 2005
+- Fix long-standing bug which caused connections to be closed if an ssh-agent
+socket was no longer available
+- Print a warning if we seem to be blocking on /dev/random
+(suggested by Paul Fox)
+- Fixed a memory leak in DSS code (thanks to Boris Berezovsky for the patch)
+- dbclient -L no longer segfaults, allocate correct buffer size (thanks
+to David Cook for reporting it, and Christopher Faylor for independently
+sending in a patch)
+- Added RSA blinding to signing code (suggested by Dan Kaminsky)
+- Rearranged bignum reading/random generation code
+- Reset the non-blocking status on stderr and stdout as well as stdin,
+fixes a problem where the shell running dbclient will exit (thanks to
+Brent Roman for reporting it)
+- Fix so that all file descriptors are closed so the child shell doesn't
+inherit descriptors (thanks to Linden May for the patch)
+- Change signkey.c to avoid gcc 4 generating incorrect code
+- After both sides of a file descriptor have been shutdown(), close()
+it to avoid leaking descriptors (thanks to Ari Hyttinen for a patch)
+- Update to LibTomCrypt 1.05 and LibTomMath 0.35
+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)
+- Fix for problems detecting openpty() with uClibc - many thanks to various
+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 Fr�d�ric 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.

+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 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.
