+    <p><!-- https://go.dev/issue/53693, https://go.dev/cl/504884 -->
+      The new methods <code>AppendEncode</code> and <code>AppendDecode</code> added to
+      each of the <code>Encoding</code> types in the packages
+      <a href="/pkg/encoding/base32"><code>encoding/base32</code></a>,
+      <a href="/pkg/encoding/base64"><code>encoding/base64</code></a>, and
+      <a href="/pkg/encoding/hex"><code>encoding/hex</code></a>
+      simplify encoding and decoding from and to byte slices by taking care of byte slice buffer management.
+    </p>
+
+    <p><!-- https://go.dev/cl/505236 -->
+      The methods
+      <a href="/pkg/encoding/base32#Encoding.WithPadding"><code>base32.Encoding.WithPadding</code></a> and
+      <a href="/pkg/encoding/base64#Encoding.WithPadding"><code>base64.Encoding.WithPadding</code></a>
+      now panic if the <code>padding</code> argument is a negative value other than
+      <code>NoPadding</code>.
