+* VirtualBox (and maybe VMWare too) do not implement the hard disk
+ synchronize_cache command so a panic or hard shutdown may corrupt
+ the filesystem. Because of this and also the fact that most
+ user-specified hard drives are not the 200GB minimum recommended
+ for HAMMER, we recommend that you install UFS on the virtual
+ hard drive and not HAMMER.
+
+* **GUI ISO (2.4.0 only)** installs a bad /boot/beastie.4th file which will
+ cause a HAMMER install on the HD boot to fail. You can fix
+ this by booting from the DVD again, logging in as root,
+ mounting /dev/ad0s1a /mnt (or da0s1a or whatever the hard
+ drive winds up being), and editing /mnt/beastie.4th. Please
+ remove the /boot prefix from the two include lines near the
+ top. They should read: 'include screen.4th' and 'include frames.4th'.
+
+* **When to install UFS** - A HAMMER setup (actually BOOT+HAMMER) is
+ the default installation but users with hard drives less then 50GB should
+ probably select a UFS install instead of HAMMER. HAMMER is designed
+ for larger hard drives, not tiny little hard drives or small virtual drives.
+ Users who insist on using HAMMER on a small drive anyway should at least
+ 'chflags nohistory /usr/obj /var/crash'.
+
+## Issues in 2.4.0 which are fixed in 2.4.1
+
+* Issues with kqueue and SIGIO not working properly on pipes
+ have been fixed. This issue affected numerous programs
+ including postfix, dovecot, and others, which use pipes and
+ kqueue for I/O notification.
+* 64-bit kernels were unable to probe USB mass storage devices.
+* cdrecord sometimes paniced after burning completed.
+* Kernel failed to finish CAM probes during boot.
+ (Note that some drivers may still register their CAM busses too
+ late, and this problem has not yet been tracked down).
+* Manual pages specified with relative paths which include a
+ directory component did not work.
+* Misc. setuid/setgid issues with exec and [f]chdir, operations
+ sometimes failed.
+* Installer's beastie.4th (boot loader issues) have been corrected.
+* Boot loader now contains real-mode fixes which may improve booting
+ from USB memory sticks.
+* tcsh updated (fixes incorrect default autologout settings)
+* Added support for VIA Nano and VIA C7
+* Added support for probing OpenBSD slices
+* Misc manual page improvements.
+
+People can checkout the release branch and compile up a new kernel
+at any time, or wait for the incremental release.
