+<ul>
+  <li>GCC can now generate debugging information
+      in <a href="https://ctfstd.org">CTF</a>, a lightweight debugging
+      format that provides information about C types and the
+      association between functions and data symbols and types.  This
+      format is designed to be embedded in ELF files and to be very
+      compact and simple.  A new command-line
+      option <code>-gctf</code> enables the generation of CTF.
+  </li>
+  <li>GCC can now generate debugging information in BTF.  This is a
+      debugging format mainly used in BPF programs and the Linux
+      kernel.  The compiler can generate BTF for any target, when
+      enabled with the command-line option <code>-gbtf</code>
+  </li>
