The DragonFly 2.4 release is here!
Three release options are now available: Our bare-bones CD ISO, a DVD ISO which includes a fully operational X environment, and a bare-bones bootable USB disk-key image (1G disk keys recommended).
In addition we will for the first time be shipping a 64-bit ISO. 64-bit support is stable but there will only be limited
-pkgsrc support in this release.
+pkgsrc support in this release. Both the bare-bones CD ISO and a bootable USB disk-key image are available for the 64-bit release.
## Availability
The release ISO images should be available on most of the [[mirrors|mirrors]]. If the ISO is not available on a certain mirror, please try another one or download it from the DragonFly FTP server.
+**Special Note on 2.4.1 mirror availability** - Unfortunately one of our primary mirrors, which other mirrors use as a source, had a snafu
+that probably will not be fixed any time soon. Our second fastest mirror is Avalon, so please use that to obtain the 2.4.1 ISOs and IMGs
+you desire.

### pkgsrc packages
We offer over 6000 pre-built [pkgsrc](http://www.pkgsrc.org) packages for this release. The [pkg_radd(1)](http://leaf.dragonflybsd.org/cgi/web-man?command=pkg_radd§ion=ANY) utility may be used to download pre-built binary packages. By default this script will query the main package site for a random redirect to one of our mirrors. The path can be overridden by setting BINPKG_SITES in `/etc/settings.conf`.
well as the pkgsrc/wip (work in progress) repo at git://git.dragonflybsd.org/pkgsrc.git and we recommend that
users use it instead of pulling from NetBSD with CVS. Our GIT mirror is updated four times a day.

**VirtualBox and VMWare users** - Unless your virtual hard disk is 50G or larger we recommend
doing a UFS install and not the default HAMMER install. We also recommend installing from the CD ISO
and not the DVD ISO. The DVD ISO HAMMER install has bugs (see [[Known Release Issues|issues24]]).

The /dev filesystem is now mounted by the kernel after it mounts the root filesystem. All major and
minor numbers have changed and the old /dev is no longer meaningful. People who use jails or chroots
will need to adjust their scripts to either mount_null /dev into their jails and chroots or to make
With this release the libc major number has also been bumped from 6 to 7. Applications should remain
fairly compatible across the upgrade but we recommend that all applications be recompiled and/or

With this release our new native AHCI driver is now standard. If your system is AHCI-capable and
AHCI-enabled the new driver will take over from NATA and drives may wind up being renamed due to
