       TODO: <a href="https://go.dev/cl/448897">https://go.dev/cl/448897</a>: os: remove special casing of NUL in Windows file operations
     </p>
+    <p><!-- https://go.dev/issue/52747, CL 405275 -->
+      On Windows, <a href="/pkg/os/#File.Stat"><code>File.Stat</code></a>
+      now uses the file handle to retrieve attributes when the file is a directory.
+      Previously it would use the path passed to
+      <a href="/pkg/os/#Open"><code>Open</code></a>, which may no longer be the file
+      represented by the file handle if the file has been moved or replaced.
+      This change modifies <code>Open</code> to open directories without the
+      <code>FILE_SHARE_DELETE</code> access, which match the behavior of regular files.
+    </p>
+    <p><!-- https://go.dev/issue/36019, CL 405275 -->
+      On Windows, <a href="/pkg/os/#File.Seek"><code>File.Seek</code></a> now supports
+      seeking to the beginning of a directory.
