2014.63 - Wednesday 19 February 2014

- Fix ~. to terminate a client interactive session after waking a laptop
  from sleep.

- Changed port separator syntax again, now using host^port. This is because
  IPv6 link-local addresses use %. Reported by Gui Iribarren

- Avoid constantly relinking dropbearmulti target, fix "make install"
  for multi target, thanks to Mike Frysinger

- Avoid getting stuck in a loop writing huge key files, reported by Bruno
  Thomsen

- Don't link dropbearkey or dropbearconvert to libz or libutil, 
  thanks to Nicolas Boos

- Fix linking -lcrypt on systems without /usr/lib, thanks to Nicolas Boos

- Avoid crash on exit due to cleaned up keys before last packets are sent,
  debugged by Ronald Wahl

- Fix a race condition in rekeying where Dropbear would exit if it received a
  still-in-flight packet after initiating rekeying. Reported by Oliver Metz.
  This is a longstanding bug but is triggered more easily since 2013.57

- Fix README for ecdsa keys, from Catalin Patulea

- Ensure that generated RSA keys are always exactly the length
  requested. Previously Dropbear always generated N+16 or N+15 bit keys.
  Thanks to Unit 193

- Fix DROPBEAR_CLI_IMMEDIATE_AUTH mode which saves a network round trip if the
  first public key succeeds. Still not enabled by default, needs more
  compatibility testing with other implementations.

- Fix for port 0 forwarding in the client and port forwarding with Apache MINA SSHD. Thanks to 

- Fix for bad system linux/pkt-sched.h header file with older Linux
  kernels, from Steve Dover

- Fix signal handlers so that errno is saved, thanks to Erik Ahlén for a patch
  and Mark Wickham for independently spotting the same problem.
