1 # DragonFly Release 2.4 - XXX $date
3 The DragonFly 2.4 release is here! XXX release text here
5 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 (less than XXX M).
9 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.
17 We offer over XXXX 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.
19 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:
