1 # DragonFly Release 2.10
2 ## 25 April 2011 (2.10.1)
4 The DragonFly 2.10 release is here!
8 **Hammer Deduplication** -
10 **Packet Filter (pf)** - Pf was updated to a version based upon OpenBSD 4.4. The previous version of pf in DragonFly was based on OpenBSD 4.2.
12 **MP Performance** - The MPLOCK (The primary lock, that when held ensures only a single cpu is operating within the kernel) has been removed from every area except the VM system. is one of the few non-academic operating systems to use a primary sychronization mechanism that is not a blocking mutex
14 **Overall Performance** - DragonFly now offers significant performance gains over previous releases, especially for machines using AHCI or implementing swapcache(8).
18 Three release options are now available for 32-bit as well as for 64-bit.
20 * An ISO, to be burned to a physical cd or used as an image to install a virtual machine.
21 * A bootable USB disk-key image (minimum 1G USB stick needed)
22 * A GUI bootable USB disk-key image with a full X environment (4G USB stick needed).
24 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 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
34 We offer roughly 10,000 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. The path can be overridden by setting BINPKG_BASE in `/etc/pkg_radd.conf`.
36 To get a list of all packages, let [pkg_search(1)](http://leaf.dragonflybsd.org/cgi/web-man?command=pkg_search§ion=ANY) download the summary file for that release:
40 We supply a Makefile in `/usr` to track the pkgsrc tree and we supply a Git mirror of the NetBSD pkgsrc CVS repo at `git://git.dragonflybsd.org/pkgsrcv2.git`. We recommend that users use it, instead of pulling from NetBSD with CVS. Our Git mirror is updated several times a day.
42 ## DragonFly 2.10 Special Installation and Upgrade Notes
44 **VirtualBox, Virtual PC, 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 GUI IMG. A more serious installation should use HAMMER with at least a 50G disk image and can install from the GUI IMG.
46 **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.)
