+<ul>
+  <li>New features
+    <ul>
+      <li>The new command-line option <code>-mexplicit-relocs</code> decides whether
+          to use the assembler relocation operator when dealing with symbolic addresses.
+          It is enabled by default when GCC is configured to use a compatible assembler.
+      </li>
+      <li>Avoid using the GOT to access external symbols when the new
+          <code>-mdirect-extern-access</code> command-line option is specified.
+      </li>
+      <li>The <a href="https://gcc.gnu.org/onlinedocs/gcc/LoongArch-Variable-Attributes.html#LoongArch-Variable-Attributes"><code>model</code></a>
+          variable attribute has been added.
+      </li>
+    </ul>
+  </li>
+  <li>Built-in functions
+    <ul>
+      <li>The <code>rint</code> and <code>copysign</code> mathematical builtins
+          (and their float variants) are now implemented as inline LoongArch intrinsics.
+      </li>
+      <li>The <code>lrint</code>, <code>logb</code>, <code>scalbln</code>,
+          <code>scalbn</code> and <code>ldexp</code> mathematical builtins (and their
+          float variants) are now implemented as inline LoongArch intrinsics when using
+          <code>-fno-math-errno</code>.
+      </li>
+      <li>The <code>lceil</code> and <code>lfloor</code> mathematical builtins
+          (and their float variants) are now implemented as inline LoongArch intrinsics
+          when using <code>-ffp-int-builtin-inexact</code>.
+      </li>
+    </ul>
+  </li>
+  <li>Subprojects Support
+    <ul>
+      <li><code>libvtv</code> now supports LoongArch architecture.</li>
+      <li><code>libitm</code> now supports LoongArch architecture.</li>
+      <li>LoongArch supports address sanitizers other than <code>hwasan</code> and <code>tsan</code>.</li>
+    </ul>
+  </li>
