 <li>The Mitchell &amp; Reeds LFSR generator provided by
 <a href="/pkg/math/rand/#Source"><code>math/rand</code>’s <code>Source</code></a>
 has been replaced by two more modern pseudo-random generator sources:
-<a href="/pkg/math/rand/v2/#ChaCha8"><code>ChaCha8</code></a>
+<a href="/pkg/math/rand/v2/#ChaCha8"><code>ChaCha8</code></a> and
 <a href="/pkg/math/rand/v2/#PCG"><code>PCG</code></a>.
 ChaCha8 is a new, cryptographically strong random number generator
 roughly similar to PCG in efficiency.
