+      <p>The interface between the ABI-specific backends and the truss
+	core was refactored, reducing duplicated code.  This prompted
+	additional follow-on work to add support for more ABIs, including
+	aarch64 and CloudABI.</p>
+
+      <p>In addition, ptrace(2) was extended to return more
+	information about the currently executing system call.  This
+	restored behavior that had been present in a previous verison of
+	truss of knowing the correct number of arguments for all system
+	calls.</p>
+
+      <p>The fork-following support in truss was reworked to use
+	native fork following in ptrace(2) rather than forking a new truss
+	process for each child of a traced process.</p>
+
+      <p>Support for decoding more arguments has also been added in
+	the last quarter as well.
