<li>Tighter pledge for <a href="https://man.openbsd.org/at.1">at(1)</a>.

<li>Fixed and simplified pledge logic for

<a href="https://man.openbsd.org/nc.1">nc(1)</a>.

<li>More application of

<a href="https://man.openbsd.org/recallocarray.3">recallocarray(3)</a>

in userland, and tracked sizes to

<a href="https://man.openbsd.org/free.9">free(9)</a> in the kernel.

<li>Achieve higher levels of paranoia regarding structure packing, and

clear many kernel objects before passing to userland.

<li>Disable some optimizations in

<a href="https://man.openbsd.org/clang.1">clang(1)</a>

due to incompatibility with security.

<li>For instance, cope with

<a href="https://man.openbsd.org/clang.1">clang(1)</a>'s assumption

that static or const

objects placed in unknown sections (such as .openbsd.randomdata)

are surely always 0, and therefore such memory accesses can be

<a href="https://man.openbsd.org/azalia.4">azalia(4)</a> to avoid static

noise in speakers and headphones on reboot.

<li>Fix i386 boot regression seen on very old 486DX CPUs.

<li>New <a href="https://man.openbsd.org/witness.4">witness(4)</a> tool

for debugging lock order issues in the kernel.

The tool is not built in by default, and only amd64, hppa and i386

are supported.

<li>Modernize some bizzare tty behaviours of getty(8).

<li>Some subtle changes to pledge(2) to satisfy requirements observed

in real life.

<li>Prefer use of waitpid(2) rather than wait(3) where possible, to

avoid problems with pre-existing children.

<li>Rewrite swaths of machine-dependent system call stub code in ld.so(1)

new-style private keys. Fixes problems related to private key

handling for no-OpenSSL builds.

<li>ssh(1): warn and do not attempt to use keys when the public and

private halves do not match.

<li>sftp(1): don't print verbose error message when ssh disconnects

from under sftp.

<li>sshd(8): fix keepalive scheduling problem: activity on a forwarded

parsing and formatting,

including automatic line wrapping inside table columns.

<li>Many improvements to

parsing and formatting, including better font selection,

recognition of well-known mathematical function names, and writing

of <code><mn></code> and <code><mo></code> HTML tags.
