         time is calculated.  (actual/average currently supported).
     + Addition of fixed time stepping option in Application/State system.
     + Addition of code to allow control of depth testing via
-        Application::setDepthTestParams
+        Application::setDepthBufferParams
     * Fixed X11 fullscreen mode 
     * Removed ALUT dependencies by adding custom WAV loading code
     * Mouse move events now give relative position.
