-  TODO: <a href="https://go.dev/cl/432898">https://go.dev/cl/432898</a>: errors, fmt: add support for wrapping multiple errors
+  Go 1.20 expands support for error wrapping to permit an error to
+  wrap multiple other errors.
+</p>
+<p>
+  An error <code>e</code</e> can wrap more than one error by providing
+  an <code>Unwrap</code> method that returns a <code>[]error</code>.
+</p>
+<p>
+  The <a href="/pkg/errors/#Is"><code>errors.Is</code></a> and
+  <a href="/pkg/errors/#As"><code>errors.As</code></a> functions
+  have been updated to inspect multiply wrapped errors.
+</p>
+<p>
+  The <a href="/pkg/fmt/#Errorf"><code>fmt.Errorf</code></a> function
+  now supports multiple occurrances of the <code>%w</code> format verb,
+  which will cause it to return an error that wraps all of those error operands.
+</p>
+<p>
+  The new function <a href="/pkg/errors/#Join"><code>errors.Join</code></a>
+  returns an error wrapping a list of errors.
