Some netgraph string length constants have been changed. This
change requires the netgraph kernel modules and all netgraph
userland components to be in sync. Especially users who require
netgraph to boot need to make sure to have world and kernel in
sync before rebooting.
The statfs structure has been updated with 64-bit fields to allow
accurate reporting of multi-terabyte filesystem sizes. You should
build and boot a new kernel BEFORE doing a `make world' as the new
kernel will know about binaries using the old statfs structure,
but an old kernel will not know about the new system calls that
support the new statfs structure. Running an old kernel after a
`make world' will cause programs such as `df' that do a statfs
system call to fail with a bad system call.

The i386 APIC_IO kernel option has been replaced by
'device apic'. The ACPI module has also been temporarily
'device apic'. The ACPI module has also been temporarily
disabled, so ACPI must be statically compiled into your
kernel using 'device acpi' if you wish to use the ACPI driver.
