+      The <a href="/pkg/strconv/#NumError"><code>NumError</code></a>
+      type now has
+      an <a href="/pkg/strconv/#NumError.Unwrap"><code>Unwrap</code></a>
+      method that may be used to retrieve the reason that a conversion
+      failed.
+      This supports using <code>NumError</code> values
+      with <a href="/pkg/errors/#Is"><code>errors.Is</code></a> to see
+      if the underlying error
+      is <a href="/pkg/strconv/#pkg-variables"><code>strconv.ErrRange</code></a>
+      or <a href="/pkg/strconv/#pkg-variables"><code>strconv.ErrSyntax</code></a>.
