+    <p>These posts explain how to handle CPU exceptions using naked functions. Historically, these posts were the main exception handling posts before the <code>x86-interrupt</code> calling convention and the <code>x86_64</code> crate existed. Our new way of handling exceptions can be found in the <a href="{{ get_url(path="./first-edition/posts/09-handling-exceptions/index.md") }}">“Handling Exceptions”</a> post.</p>
