77: Patches for the OpenBSD base system are distributed as unified diffs.
78: Each patch is cryptographically signed with the
79: <a href="https://man.openbsd.org/OpenBSD-6.6/signify.1">signify(1)</a> tool and contains
80: usage instructions.
81: All the following patches are also available in one
82: <a href="https://ftp.openbsd.org/pub/OpenBSD/patches/6.6.tar.gz">tar.gz file</a>
83: for convenience.
84:
85: <p>
86: Alternatively, the <a href="https://man.openbsd.org/syspatch">syspatch(8)</a>
87: utility can be used to apply binary updates on the following architectures:
88: amd64, i386, arm64.
89:
90: <p>
91: Patches for supported releases are also incorporated into the
92: <a href="stable.html">-stable branch</a>, which is maintained for one year
93: after release.
