73: Patches for the OpenBSD base system are distributed as unified diffs.
74: Each patch is cryptographically signed with the
75: <a href="https://man.openbsd.org/OpenBSD-6.3/signify.1">signify(1)</a> tool and contains
76: usage instructions.
77: All the following patches are also available in one
78: <a href="https://ftp.openbsd.org/pub/OpenBSD/patches/6.3.tar.gz">tar.gz file</a>
79: for convenience.
80:
81: <p>
82: Alternatively, the <a href="https://man.openbsd.org/syspatch">syspatch(8)</a>
83: utility can be used to apply binary updates on the following architectures:
84: amd64, i386, arm64.
85:
86: <p>
87: Patches for supported releases are also incorporated into the
88: <a href="stable.html">-stable branch</a>, which is maintained for one year
89: after release.
