+<ul>
+  <li>The <code>mips*-*-linux*</code> targets now mark object files with appropriate GNU-stack note,
+    facilitating use of non-executable stack hardening on GNU/Linux.
+    The soft-float targets have this feature enabled by default, while
+    for hard-float targets it requires use of glibc 2.31 or later.
