sysinstall(8), sysupgrade(8), as well as the games and ports.
Adopt the Aurora procedural wallpaper in display(1) and login(8).
Remove the obsolete dispd.
Juhani contributed keyboard and video mode APIs to the display protocol
and other miscellaneous changes.
dzwdz contributed the initial functioning window buttons, improved title
bar, window tiling, and minor bug fixes

This change implements a dependency tracking daemon(7) system in init with
overridable init(5) configuration, parallel startup, readiness signaling,
rotating logs, reliable stopping, and handling of leaked processes.
The /etc/init/target file is replaced by the new /etc/init/default per the
new init(5) format. The old configuration is migrated upon upgrade using an
upgrade hook.
extfs(8) now signals readiness using READYFD for fast mounting.
Filesystems that fail to be repaired are now mounted read-only.
The mounting and filesystem checking code is synchronized with sysinstall.
The duplicated array_add utility function now protects against overflows.
tix-iso-bootconfig(8) gains the --init-target option.
tix-iso-liveconfig(8) gains the --daemons option.
The bootloader will now load the /boot/random.seed file if it exists, in
which case the kernel will use it as the initial kernel entropy. The kernel
warns if no random seed was loaded, unless the --no-random-seed option was
given. This option is used for live environments that inherently have no
prior secret state. The kernel initializes its entropy pool from the random
seed as of the first things, so randomness is available very early on.
init(8) will emit a fresh /boot/random.seed file on boot to avoid the same
entropy being used twice. init(8) also writes out /boot/random.seed on
system shutdown where the system has the most entropy. init(8) will warn if
writing the file fails, except if /boot is a real-only filesystem, and
keeping such state is impossible. The system administrator is then
responsible for ensuring the bootloader somehow passes a fresh random seed
on the next boot.
/boot/random.seed must be owned by the root user and root group and must
have file permissions 600 to avoid unprivileged users can read it. The file
is passed to the kernel by the bootloader as a multiboot module with the
command line --random-seed.
If no random seed is loaded, the kernel attempts a poor quality fallback
where it seeds the kernel arc4random(3) continuously with the current time.
The timing variance may provide some effective entropy. There is no real
kernel entropy gathering yet. The read of the CMOS real time clock is moved
to an early point in the kernel boot, so the current time is available as
fallback entropy.
The kernel access of the random seed module is supposed to be infallible
and happens before the kernel log is set up, but there is not yet a failsafe
API for mapping single pages in the early kernel.
sysupgrade(8) creates /boot/random.seed if it's absent as a temporary
compatibility measure for people upgrading from the 1.0 release. The GRUB
port will need to be upgraded with support for /boot/random.seed in the
10_sortix script. Installation with manual bootloader configuration will
need to load the random seed with the --random-seed command line. With GRUB,
this can be done with: module /boot/random.seed --random-seed
