[Matt Johnston]

Hi all,

After much too long a delay Dropbear 0.53 is now released.
Tarballs are located at http://matt.ucc.asn.au/dropbear/ as usual,
changes are as listed below.

Cheers,
Matt

0.53 - Thurs 24 February 2011

- Various performance/memory use improvements

- Client agent forwarding now works, using OpenSSH's ssh-agent

- Improve robustness of client multihop mode

- Fix a prime generation bug in bundled libtommath. This is unlikely to have
  generated any bad keys in the wild.
  See 
  https://bugzilla.redhat.com/show_bug.cgi?id=615088
  http://bugs.gentoo.org/show_bug.cgi?id=328383
  http://bugs.gentoo.org/show_bug.cgi?id=328409

- Attempt to build against system libtomcrypt/libtommath if available. This
  can be disabled with ./configure --enable-bundled-libtom

- Make -K (keepalive) and -I (idle timeout) work together sensibly in the client.
  The idle timeout is no longer reset by SSH_MSG_IGNORE packets.

- Compile fix if ENABLE_CLI_PROXYCMD is disabled

- /usr/bin/X11/xauth is now the default path

- Client remote forward (-L/-R) arguments now accept a listen address

- In uClinux avoid trashing the parent process when a session exits

- Blowfish is now disabled by default since it has large memory usage

- Add option to change zlib windowbits/memlevel. Use less memory by default

- DROPBEAR_SMALL_CODE is now disabled by default

- SSH_ORIGINAL_COMMAND environment variable is set by the server when an
  authorized_keys command is specified.

- Set SSH_TTY and SSH_CONNECTION environment variables in the server

- Client banner is now printed to standard error rather than standard output

- Capitalisation in many log messages has been made consistent. This may affect
  scripts that parse logfiles.
