9ad8146e 1# DragonFly Release 3.4
59472ff9 3Version 3.4.0 released xx April 2013.
9ad8146e 4
5## Big-ticket items
59472ff9 7### Experimental packaging system: dports
aba95e00 9John Marino has created a system, DPorts, that uses the FreeBSD ports system to build ports for DragonFly, and uses [pkgng]( to manage the binary packages produced from those ports.
59472ff9 10
aba95e00 11The default packaging system on DragonFly is pkgsrc. To use DPorts, you must remove or disable pkgsrc packages. Pkgsrc and DPorts cannot be used at the same time, or have packages mixed together. See the [DPorts Howto page](docs/docs/howtos/HowToDPorts/) for details on installing and using DPorts. Note: this is the first release with DPorts, and this is still experimental.
59472ff9 12
9ad8146e 13### Performance improvements under extreme load
aba95e00 15The process of testing [poudriere](, the dports build system, exposed stability issues when repeatedly mounting and unmounting many tmpfs systems on large multicore (48) systems. These issues have been fixed. In addition to stability, several changes were made to improve performance in situations with heavy processor and disk usage.
17### Experimental HAMMER2 included
19The next version of HAMMER, HAMMER2, is in DragonFly. It is not ready to use for storage at this point. However, it is [possible to set it up]( to experiment with the messaging protocols.

21### New USB stack
aba95e00 23[USB4BSD]( is available this release, though not by default. More USB devices are compatible with DragonFly, and xhci (USB 3.0) users may be able to take full advantage of their newer hardware. Since this is a new feature, it is available in 3.4 but *not* built by default. See the [original announcement]( for how to do so. This feature was available in DragonFly 3.2 but is still experimental.

25## Availability
f83492af 27Two release options are now available for 32-bit as well as for 64-bit. 64-bit installations are recommended if you do not need the Linux emulation layer.
9ad8146e 28
29* An ISO, to be burned to a physical CD or used as an image to install a virtual machine.
30* A bootable USB disk-key image. (minimum 2G USB stick needed)
32The 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 master site. Each image is in the "Live CD" format, meaning that it boots into a running and fully functional DragonFly system, which can be used for testing or system recovery tasks as well as installation. Check the [hardware page]( or boot a Live CD to check for compatibility.
35### MD5 sums
37MD5 sums for the compressed images:
39* MD5 (dfly-i386-3.2.1_REL.img.bz2) = a592...
40* (FIXME)
42MD5 sums for the uncompressed images:
44* MD5 (dfly-i386-3.2.1_REL.img) = 52c416d...
45* (FIXME)
47### pkgsrc packages
f83492af 49Pkgsrc packages have not been pre-built for this release. We suggest building from source for pkgsrc installation.
9ad8146e 50
51We supply a Makefile in `/usr` to track the pkgsrc tree and we supply a Git mirror of the NetBSD pkgsrc CVS repo at `git://`. We recommend that users use it, instead of pulling from NetBSD with CVS. Our Git mirror is updated several times a day. Type 'make' in /usr to see the available commands for performing these actions.
53## DragonFly 3.4 Special Installation and Upgrade Notes
f83492af 55**Disk size warning** - Installations using HAMMER should be to disks over 50G in size. HAMMER history will consume disk space quickly. Either use UFS on smaller disks, or prune your file history carefully.
9ad8146e 56
57**Virtual PC users** - Virtual PC does not supply serial numbers for the virtual disks. The system may need to be manually directed in the boot loader if the disk identifier changes. (Hit ? in the boot loader for a list of available volumes.)
59**Qemu users** - If you see a large number of error messages on the console when booting, you may need to boot DragonFly with ACPI disabled. This can be done in the menu presented at initial boot. If that doesn't help, try placing hw.ioapic_enable=0 in /boot/loader.conf.
61**Installer Crypt Options** - The installer can encrypt the root volume and the swap volume. It will not work properly for other volumes despite any additional check-boxes you might see. Installer and boot-time support works but is still a bit rough around the edges. Performance will be relatively high on multi-core machines.
