      • Prevent sftp(1) from crashing when given a "-" without a command; also, allow whitespace to follow a "-". (bz#1691)
      • After sshd(8) receives a SIGHUP, ignore subsequent HUPs while sshd(8) re-execs itself; prevents two HUPs in quick succession from resulting in sshd(8) dying. (bz#1692)
      • Clarify in sshd_config(5) that StrictModes does not apply to ChrootDirectory; permissions and ownership are always checked when chrooting. (bz#1532)

      • Don't escape backslashes when displaying the SSH2 banner. (bz#1533)
      • Don't unnecessarily dup() the in and out fds for sftp-server(8). (bz#1566)
      • Force use of the correct hash function for random-art signature display. (bz#1611)
      • Do not fall back to adding keys without constraints when the agent refuses the constrained add request. (bz#1612)
      • Fix a race condition in ssh-agent(1) that could result in a wedged or spinning agent. (bz#1633)
      • Flush stdio before exec() to ensure that everything has made it out before the streams go away. (bz#1596)

    If only we had the technology to download stickers :P

    I think a part of my tax return has found a home, soon as it comes in ;)

      You can obtain blank sticker paper, and print off your own.

    Another great release. Thanks devs!

  4. By Anonymous Coward (foldingstock) on

    I pre-ordered for the wonderful artwork that comes with the install set and to support the project. OpenBSD is a wonderful operating system.

    I plan on upgrading my home server from 4.6->4.7 very soon.

  5. By Howard Pepper (HowiPepper) on

    Received my CD set a week and a half ago and installed it in a VM for testing, waiting for the full release. Unfortunately my OpenBSD computer croaked out on me today, so I'm going to have to wait for my newly ordered one to arrive before committing 4.7 to hardware!
