As posted in my email to users@: Version 3.4 of DragonFly is officially out.

The release ISO/IMG files are all available at the usual mirrors:

http://www.dragonflybsd.org/mirrors/

The release notes have details on all the changes:

http://www.dragonflybsd.org/release34/

If you are planning to try the new dports system for installing third-party software, check the DPorts Howto page:

http://www.dragonflybsd.org/docs/howtos/HowToDPorts/

If you have an installed DragonFly 3.2 system and you are looking to upgrade, these (not directly tested) steps should work, as root:

cd /usr/src
git fetch origin
git branch DragonFly_RELEASE_3_4 origin/DragonFly_RELEASE_3_4
git checkout DragonFly_RELEASE_3_4

… And then go through the normal buildworld/buildkernel process found in /usr/src/UPDATING.  If you are running a generic kernel, that can be as simple as

make buildworld && make buildkernel && make installkernel && make installworld && make upgrade

(and then reboot)

If you encounter problems, please report them at bugs.dragonflybsd.org.  I get better at testing for each release, but I also get better at discovering new problems just after release.
