Patches for the OpenBSD base system are distributed as unified diffs.
Each patch is cryptographically signed with the
<a href="https://man.openbsd.org/OpenBSD-7.2/signify.1">signify(1)</a> tool and contains
usage instructions.
All the following patches are also available in one
<a href="https://ftp.openbsd.org/pub/OpenBSD/patches/7.2.tar.gz">tar.gz file</a>
for convenience.

<p>
Alternatively, the <a href="https://man.openbsd.org/syspatch">syspatch(8)</a>
utility can be used to apply binary updates on the following architectures:
amd64, i386, arm64.

<p>
Patches for supported releases are also incorporated into the
<a href="stable.html">-stable branch</a>.
