-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).
+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.
+**Special Note on 2.4.1 mirror availability** - Unfortunately one of our primary mirrors, which other mirrors use as a source, had a snafu
+that probably will not be fixed any time soon. Our second fastest mirror is avalon.dragonflybsd.org, so please use that to obtain the 2.4.1 ISOs and IMGs
+you desire if you cannot find them on a more local mirror.

### pkgsrc packages
-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`.

# 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 2.4.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 (2.4.0 only)** - You will get a 'guard1x fail @...' loader panic.
+See [[Known Release Issues|issues24]] on how to fix.
+
+2.4.x is a bigger release than normal. The single most invasive change is the introduction of DEVFS.
+The /dev filesystem is now mounted by the kernel after it mounts the root filesystem. All major and
+minor numbers have changed and the old /dev is no longer meaningful. People who use jails or chroots
+will need to adjust their scripts to either mount_null /dev into their jails and chroots or to make
+independent DEVFS mounts via mount_devfs into their jails and chroots.
+
+Within DEVFS the entire tty/pty scheme has changed. Users upgrading from 2.2 need to be absolutely
+sure to upgrade their world and kernel at the same time or fireworks may ensue.
+
+With this release the libc major number has also been bumped from 6 to 7. Applications should remain
+fairly compatible across the upgrade but we recommend that all applications be recompiled and/or
+fresh binary packages be loaded from pkgsrc. Certain pty-based applications such as "screen"
+may require recompiling.
+
+With this release our new native AHCI driver is now standard. If your system is AHCI-capable and
+AHCI-enabled the new driver will take over from NATA and drives may wind up being renamed due to
+this. For example, ad6 might become da0. Any legacy ATA ports will continue to be probed by the NATA
+driver but their drives may be named differently. USB mass storage devices will also be numbered starting
+at 8, for example da8, to avoid conflicting with lower-numbered da* devices.
+
+DEVFS now probes serial numbers. The serial numbers for all ATA, SATA, and SCSI devices will be
+recorded by DEVFS in /dev/serno/. USB mass storage devices are more problematic
+as the on-device controllers typically do not implement serial number reporting. Users are
+encouraged to use /dev/serno/ paths in their /etc/fstab and /etc/rc.conf, and
+to even specify the root mount in /boot/loader.conf using a devfs-relative serial number
+path such as: vfs.root.mountfrom="hammer:serno/AB34394.s1d". The use of serial numbers to
+specify the location of mass storage devices allows you to attach those devices in virtually any
+manner without confusing the system. This is particularly important as SATA Port Multiplier
+enclosures and systems with large numbers of SATA and E-SATA connectors become prevalent.
+
+The installer now installs (and we recommend) a BOOT+HAMMER setup by default. The installer will
+also reference mount points by serial numbers.
+
+We expect there will be numerous issues with this release and we intend to roll a 2.4.1
+out in about a month to address what comes up. [[Known Release Issues|issues24]]
+
+So upgrading to 2.4.x will certainly be a bit painful for users of 2.2.x or earlier releases. We
+believe the pain will be well worth the effort.
+
## DragonFly 2.4.0 Release Notes
### Release Improvements
-### Kernel changes
+> ### Kernel changes
* acpi(4): Import acpica-unix-20090521.
- * devfs(5): Replaced the static /dev directory with a dynamic device file system written by Alex Hornung during the Google Summer of Code 2009.
- * ddb(4): Fix an IPI messaging lockup which can occur while in DDB.
- * disklabel64(5): Add UFS + HAMMER boot support (was previously just HAMMER boot support)
+ * acpi(4): Improved power & frequency management for cpus.
+ * acpi(4): Significantly improved APIC support.
+ * **buf/bio: New read-prioritizing bioq sort algorithm.** The new algorithm does a much better job
+ prioritizing reads over writes and also contains features to avoid starving-out writes. It
+ works best with CAM based drivers but NATA uses some of its functionality too.
+ * buf/bio: Make biowait(), getpbuf(), and most other buf/bio functions MPSAFE.
+ * buffer-cache: Improved pipe-lining for writes.
+ * bpf(4): Add autocloning support
+ * **devfs(5): Replaced the static /dev directory with a dynamic device file system written by Alex Hornung during the Google Summer of Code 2009.**
+ * All block devices now auto-probe their slices and partitions.
+ * All block devices now auto-probe serial numbers and may be mounted and otherwise referenced by serial number.
+ * loader.conf now supports specifying the root device by serial number.
+ * Autocloning support for cloning devices such as VN.
+ * ddb(4): Fix an IPI messaging lockup which can occur while in ddb(4).
+ * **disklabel64(5): Add UFS + HAMMER boot support** (was previously just HAMMER boot support).
* drm(4): Sync code with latest from FreeBSD.
- * msdos(5): Fixed a number of bugs
- * usched_set: Add USCHED_CPU_GET for retrieving the current CPU
+ * ext2fs: Support variable inode size (from FreeBSD).
+ * mountctl/mount -v: New infrastructure for reporting mount flags.
+ * NFS
+ * **The client-side RPC code has been rewritten.** Two kernel threads are now created
+ for each NFS mount. One handles reading from the socket and the other handles
+ writing to the socket. A virtually unlimited number of RPCs may be in-flight
+ at any given moment. The days of multiplicative threads each running synchronous
+ RPCs are over!
+ * **Use TCP mounts by default as the new RPC architecture can now trivally blow
+ out UDP sockbufs.**
+ * **Hugely improved client-side performance.**
+ * Fixed fsx test regressions.
+ * Fixed Linux compatibility issues (fix bugs in readdirplus)
+ * msdos(5): Fixed a number of bugs.
+ * pci(4): Sync code with FreeBSD 7.2.
+ * Bring iscsi_initiator(4) from FreeBSD.
+ * pipe(2): Pipes are now 100% MPSAFE.
+ * Add new cred/privilege infrastructure for jail and general use.
+ * Consolidate VOP access tests in vop_helper_access().
+ * usched_set: Add USCHED_CPU_GET for retrieving the current CPU.
* revoke(2): Reimplemented the revoke code.
+ * pty: Add Unix98 ptys (/dev/ptmx and /dev/pts/*).
+ * sound: add autocloning support for dsp devices.
+ * tcp: Fixed a reestablishment bug for TCP connections if one side reboots without
+ closing the connection. A port pair could wind up becoming unusable for
+ upwards of an hour or longer.
+ * tcp: Improve performance by implementing an automatic high-water mark when
+ it is not otherwise specified, allowing hysteresis between the kernel and
+ the tcp protocol stack.
+ * tsleep: New tsleep interlock mechanics implemented to fix races.
* vkernel(7)
- * Fix entry into ddb when running a SMP vkernel. Fixes stop/cont
- * Fix startup race with I/O cothread support.
- * Fix some issues - enable ithread preemption, races, and more.

+ * Fixed startup race with I/O cothread support.
+ * Fixed some issues - enable ithread preemption, races, and more.
+ * Fixed races in stopsig() and ipisig().
+ * libkvm now understands live vkernels.
+ * libkvm: Add support for accessing a running vkernel's memory by reading its `/proc/$pid/mem` file.
