75: Patches for the OpenBSD base system are distributed as unified diffs.
76: Each patch is cryptographically signed with the
1.3 tb 77: <a href="https://man.openbsd.org/OpenBSD-6.4/signify.1">signify(1)</a> tool and contains
1.1 deraadt 78: usage instructions.
79: All the following patches are also available in one
80: <a href="https://ftp.openbsd.org/pub/OpenBSD/patches/6.4.tar.gz">tar.gz file</a>
81: for convenience.
82:
83: <p>
84: Alternatively, the <a href="https://man.openbsd.org/syspatch">syspatch(8)</a>
85: utility can be used to apply binary updates on the following architectures:
86: amd64, i386, arm64.
87:
88: <p>
89: Patches for supported releases are also incorporated into the
90: <a href="stable.html">-stable branch</a>, which is maintained for one year
91: after release.
