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