Patches for the OpenBSD base system are distributed as unified diffs.
Each patch is cryptographically signed with the
<a href="http://man.openbsd.org/OpenBSD-5.5/signify.1">signify(1)</a> tool and contains
usage instructions.
All the following patches are also available in one
<a href="https://ftp.openbsd.org/pub/OpenBSD/patches/5.5.tar.gz">tar.gz file</a>
for convenience.
<p>
Patches for supported releases are also incorporated into the
<a href="stable.html">-stable branch</a>.
