83 Patches for the OpenBSD base system are distributed as unified diffs.
84 Each patch is cryptographically signed with the
85 <a href="https://man.openbsd.org/OpenBSD-7.3/signify.1">signify(1)</a> tool and contains
86 usage instructions.
87 All the following patches are also available in one
88 <a href="https://ftp.openbsd.org/pub/OpenBSD/patches/7.3.tar.gz">tar.gz file</a>
89 for convenience.
90
91 <p>
92 Alternatively, the <a href="https://man.openbsd.org/syspatch">syspatch(8)</a>
93 utility can be used to apply binary updates on the following architectures:
94 amd64, i386, arm64.
95
96 <p>
97 Patches for supported releases are also incorporated into the
98 <a href="stable.html">-stable branch</a>, which is maintained for one year
99 after release.
