eee5414d 1# DragonFly Release 3.8
3Version 3.8.0 released 04 June 2014.
6## Big-ticket items
80c9b34b 8### Dynamic root and PAM
10PAM is now usable for other authentications systems in DragonFly. DragonFly now uses a dynamic /root to support this.
12### New USB
14USB4BSD is now default in DragonFly. USB3 devices are supported, though some network devices may not be recognized.
020d084a 16### Graphic drivers
eee5414d 17
020d084a 18The drm/i915 driver had originally been ported from FreeBSD. An ongoing synchronization job with the version present in the Linux 3.8 branch is now going on. The mid-term goal is to be able to use GPUs included in Haswell and ValleyView/Bay Trail processors.
19Supported GPUs are currently limited to HD4000 from the Ivy Bridge processor generation.
21Even if this goal has not been reached yet, the partial synchronization with the drm/i915 implementation from Linux 3.8.x has already allowed many bugs to be fixed and general driver stability to be improved.
23The drm/ttm memory manager used by the drm/radeon driver has been partially synchronized with the version present in Linux 3.9, improving its stability. Howewer, many issues remain and thus Xorg still doesn't use the drm/radeon driver by default.

25### Last 32-bit release
eee5414d 26
b12cee5d 27A 32-bit address space is now a significant limitation in the high-performance world where DragonFly lives.
29This is the last DragonFly release planned to work on i386. Please plan to upgrade to 64-bit when possible. Note that prebuilt packages for this release will only exist for 64-bit systems; 32-bit users will have to build by hand.

31## Availability
80c9b34b 3364-bit (x86_64) installations are recommended. The 32-bit (i386) should only be used if your hardware cannot support 64-bit operating systems. Each version is available as:
eee5414d 34
35* An ISO, to be burned to a physical CD or used as an image to install a virtual machine.
36* A bootable USB disk-key image. (minimum 2G USB stick needed)
38The 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](http://www.dragonflybsd.org/docs/supportedhardware/) or boot a Live CD to check for compatibility.
40"GUI" images with a desktop are not ready at release time.

50### dports packages
80c9b34b 52Packages for [[dports|docs/howtos/HowToDPorts]] on DragonFly 3.8 are available, for 64-bit platforms. The 'pkg' command will automatically access the main dports repository for DragonFly. Modify /usr/local/etc/pkg.conf if you want to change this and select a different mirror.
eee5414d 53
54If you have pkgsrc packages installed, move or rename /usr/pkg and /var/db/pkg before installing from dports. Dump databases before starting this process. Use 'pkg search' to verify the existence of your needed packages before moving the existing pkgsrc files away, and 'pkg install' to add them.
56If you need specific build options for dports packages that aren't on by default, you will need to build your own versions of the software. Download the dports src repository with 'make dports-create' in the /usr directory, and build from there.
58See the [[docs/howtos/HowToDPorts]] page for more details on using and maintaining dports.
f0565a58 60## DragonFly 3.8 Special Installation and Upgrade Notes
eee5414d 61
62This is the most important part of this page.
64* HAMMER installations should be over 50G in size to accomodate filesystem history. Otherwise, use UFS.
65* The boot loader may need manual intervention (hit ?) if you are using Virtual PC, since Virtual PC does not supply disk serial numbers.
66* Qemu users can boot with ACPI disabled or with hw.ioapic_enable=0 in /boot/loader.conf, to reduce console error message.
67* xorg may require a config file on i386 DragonFly, under VMWare.
68* The installer can only encrypt the root and swap volumes.
