   <li>Support of Intel MPX (Memory Protection Extensions) has been removed.</li>
+  <li>New ISA extension support for Intel PTWRITE was added to GCC.  PTWRITE
+      intrinsics are available via the <code>-mptwrite</code> compiler switch.
+  </li>
+  <li>GCC now supports the Intel CPU named Cascade Lake with AVX512 extensions
+      through <code>-march=cascadelake</code>. The switch enables the following
+      ISA extensions: AVX512F, AVX512VL, AVX512CD, AVX512BW, AVX512DQ, AVX512VNNI.
