+  The 64-bit MIPS architecture on OpenBSD (the <code>openbsd/mips64</code>
+  port) now supports cgo.

+<p><!-- golang.org/issue/36435 -->
+  In Go 1.16, on the 64-bit x86 and 64-bit ARM architectures on
+  OpenBSD (the <code>openbsd/amd64</code> and <code>openbsd/arm64</code>
+  ports) system calls are made through <code>libc</code>, instead
+  of directly using the machine instructions. In Go 1.17, this is
+  also done on the 32-bit x86 and 32-bit ARM architectures on OpenBSD
+  (the <code>openbsd/386</code> and <code>openbsd/arm</code> ports).
+  This ensures forward-compatibility with future versions of
+  OpenBSD.
