# DragonFly Release 2.6 ## XX March 2010 (2.6.0) The DragonFly 2.6 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. 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. ### MD5 sums * MD5 (dfly-2.6.0_REL.img.gz) = * MD5 (dfly-2.6.0_REL.iso.gz) = * MD5 (dfly-amd64-2.6.0_REL.iso.gz) = * MD5 (dfly-gui-2.6.0_REL.iso.gz) = * MD5 (dfly-2.6.0_REL.img) = * MD5 (dfly-2.6.0_REL.iso) = * MD5 (dfly-amd64-2.6.0_REL.iso) = * MD5 (dfly-gui-2.6.0_REL.iso) = ### pkgsrc packages We offer over 8000 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`. 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: # pkg_search -d We supply a Makefile in /usr to track the pkgsrc tree. We also supply a GIT mirror of the NetBSD pkgsrc CVS repo as 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. ## DragonFly 2.6.x Special Installation and Upgrade Notes **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]]). **DVD ISO HAMMER install bugs (2.6.0 only)** - You will get a 'guard1x fail @...' loader panic. See [[Known Release Issues|issues24]] on how to fix. ## DragonFly 2.6.0 Release Notes ### Release Improvements > ### Kernel changes * Imported tmpfs (efficient memory filesystem) from NetBSD. * Added support for minidumps. * Added swapcache support. * Ported POSIX Message Queues from NetBSD (Google Summer of Code Project). > ### HAMMER changes * Updated to HAMMER version 4, moving snapshot settings out of config files and moving snapshots to /var/hammer; add an UNDO and REDO FIFO to improve fsync performance. * Extended 'hammer snapls' output to print mountpoints and snapshot notes. > ### Hardware changes (non-networking) > ### Hardware changes (networking) * Imported the alc(4) driver for Atheros AR8131/AR8132 NICs > ### Userland changes * null mounts now accept -o update > ### amd64 related changes > ### Removals * The T/TCP extension is no longer supported > ### Contributed Software * Updated BIND to 9.5.2-P2 incl.
