Shamelessly copied from my own users@ post: I tagged 5.6.1 and built it earlier today.  This version has a corrected sshd_config and fixes a lockup bug in ttm. The ISO should be showing up on mirror-master.dragonflybsd.org in the next 20 minutes or so, or you can rebuild using the normal process on an existing 5.6 system:

cd /usr/src
git pull
make buildworld
make buildkernel
make installkernel
make installworld
make upgrade

If you are still on 5.4 or earlier, you need to bring in 5.6 sources, which is noted in the 5.6.0 announcement.
