+      <ul>
+
+      <li>Partial support for gcc-4.7. Ada support is poor, but other languages
+          work fairly well.</li>
+
+      <li>Support for ARM processors. Some essential gcc headers that are needed
+          to build DragonEgg for ARM are not installed by gcc. To work around
+          this, copy the missing headers from the gcc source tree.</li>
+
+      <li>Better optimization for Fortran by exploiting the fact that Fortran
+          scalar arguments have 'restrict' semantics.</li>
+
+      <li>Better optimization for all languages by passing information about
+          type aliasing and type ranges to the LLVM optimizers.</li>
