+  * harbour/include/hbsetup.h
+    + added HB_RESTRICT macro which can be used in some declarations
+      to reach better code optimization
+
+  * harbour/include/hbclass.ch
+    + added support for xbase++ compatible method declaration by:
+         METHOD <methodName1> [ , <methodNameN> ]
+
+  * harbour/source/rtl/tthreadx.prg
+    * redirect parameters passed to ::new() method to ::init() method
+      as emulation for class object new method
+    + added basic support for ::setInterval in xbasee++ THREAD class
+
+  * harbour/tests/speedtst.prg
+    ! removed unused variable cDir
