+<p>
+It is impossible to guarantee long-term compatibility with operating
+system interfaces, which are changed by outside parties.
+The <a href="/pkg/syscall/"><code>syscall</code></a> package
+is therefore outside the purview of the guarantees made here.
+As of Go version 1.4, the <code>syscall</code> package is frozen.
+Any evolution of the system call interface must be supported elsewhere,
+such as in the <code>go.sys</code> subrepository.
+For details and background, see
+<a href="https://golang.org/s/go1.4-syscall">this document</a>.
