+          <p>
+	    Optimize <c>receive</c> statements that are only waiting
+	    for messages containing a reference created before the
+	    receive. All messages that existed in the queue when the
+	    reference was created will be bypassed, as they cannot
+	    possibly contain the reference. This optimization has
+	    existed for vanilla BEAM since OTP R14.</p>

+          <p>
+	    Add validation pass to hipe compiler to detect internal
+	    errors causing primop calls that may trigger an unsafe GC
+	    at run-time. The pass can be disabled with option
+	    <c>no_verify_gcsafe</c>.</p>

+        <item>
+          <p>
+	    Make hipe compiled code work on x86_64 (amd64) with OS
+	    security feature PIE, where executable code can be loaded
+	    into a random location. Old behavior, if hipe was
+	    enabled, was to disable PIE build options for the VM.</p>
