+<p>
+  The majority of changes in this release are focused on supporting the synchronized release of NxWM, the NuttX tiny window manager.
+  That window manager is released as part of the NxWidgets package, but depends upon many of the changes in this NuttX release.
+</p>
 <p><b>New Features</b>.
   New or extended features in this release include:
 </p>
 <ul>
-  <li><b>Networking</b>.
-    Additional low-level, thread-independent socket interfaces (for NFS client support).
-  </li>
-  <li><b>RTC</b>.
-    Added a new interface call <code>clock_synchronize()</code>. 
-    This function will reload the system time from an RTC and is required when the system re-awakens from certain deep-sleep modes.
-  </li>
-  <li><b>Graphics</b>.
-    Add <i>NxConsole</i>.
-    This is a character device driver that wraps an NX window and can be re-directed for <code>stdout</code>.
-    This allows, for example, a pop-up graphics window that contains a <i>NuttShell</i> (NSH) session.
-    A test of <i>NxConsole</i> is available at <code>apps/examples/nxconsole</code>.
-  </li>
-  <li><b>Watchdog Drivers</b>.
-    Added an interface definition an &quot;upper half&quot; driver to support watchdog timers.
+  <li><b>Drivers</b>.
+    Added a watchdog timer driver infrastructure.
+    Add general support for STMicro STMPE11 I/O Expander/touchscreen device.
   </li>
-  <li><b>Calypso</b>.
-    Support for TI Calypso-based cellphones (as supported by the <i>Osmocom-BB</i> project) was contributed by members of the <i>Osmocom-BB</i> team.
-    This includes configurations for the Compal e88 and e99 phones.
-  </li>
-  <li><b>USB Device Interface</b>.
-    Needed to extend the USB device interface because there was no mechanism for passing endpoint OUT data that may need to accompany a setup request.
-  </li>
-  <li><b>STM32 drivers</b>.
-    Added some power management controls for entering reduced power consumption states.
-    An OTG FS driver was completed and partially verified
-    (this driver seems to be functional but since it has been test so lightly, it might better be listed in the next section &quot;Work in progress&quot;).
+  <li><b>STM32</b>.
+    Add support for the STM32 IWDG and WWDG watchodog timers. 
+    DMA now supports cicular buffer mode;
+    serial driver now uses circular DMA to improve Rx performance (Contributed by Mike Smith).
   </li>
-  <li><b>PIC32 drivers</b>.
-    The PIC32 Ethernet driver is now stable.
-    The PIC32 USB device controller driver is now functional (but not yet stable).
+  <li><b>STM3240G-EVAL Board</b>.
+    Add support for the LCD and for the STMPE11 I/O Expander as a touchscreen controller.
   </li>
-  <li><b>PIC32 boards</b>.
-    Added support for the Sure DB-DP11212 PIC32 General Purpose Demo Board.
-    There is now a PIC32 Starter Kit that provides NSH only through a Telnet connection.
+  <li><b>PIC32 Boards</b>.
+    Board support for the Mikroelektronika PIC32MX7 Multimedia Board (MMB) and for the Sparkfun UBW32 PIC32 board.
   </li>
-  <li><b>Build System</b>.
-    Some header files were moved into <code>include/nuttx</code>.
-    The goal is to move any non-standard header files to <code>include/nuttx</code> or <code>include/arch</code>.
-    Moved <code>include/math.h</code> to <code>include/nuttx/math.h</code>;
-    this file is now only instantiated as the <i>system</i> <code>math.h</code> if <code>CONFIG_ARCH_MATH_H=y</code> is defined.
+  <li><b>NX</b>.
+    Framed windows are now draw in three colors instead of just two.
+    Numerous other extensions needed to support NxWM (see the ChangeLog for details).
   </li>
-  <li><b>Tools</b>.
-    Added <code>tools/cmpconfig.c</code>, a tool for comparing two configuration files.
+  <li><b>Library</b>.
+    Add <code>prctl()</code> command that can be used to setting and getting the names of threads.
+    This (plus several other improvements and bug fixes) are part of a larger effort to improve task monitoring capabilities.

-    * configs/sure-pic32mx: Add support for the Sure DB-DP11212 PIC32 General
-      Purpose Demo Board
-    * arch/arm/src/stm32/stm32_usbhost.c/.h:  Add files that will (eventually)
-      hold an STM32 USB host driver (the initial check-in is the NuttX LPC17
-      USB host driver with name changes only).
-    * arch/arm/src/stm32/chip/stm32_otgfs.h:  STM32 USB OTG FS register
-      definitions (not complete on initial check-in).
-    * net/connect.c:  Add another low level, thread-independent socket interface
-      for use within the OS.
-    * arch/mips/src/pic32mx/pic32mx_ethernet.c:  The PIC32 Ethernet driver
-      is now stable on the PIC32 Starter Kit.
-    * configs/pic32-starterkit/nsh2:  Add a PIC32 Ethernet Starter Kit NSH
-      configuration that has no serial console; all interaction is done via
-      Telnet.
-    * net/netdev_sem.c:  Correct a deadlock condition by making a seamphore
-      recursive.  To my knowledge this deadlock only occurs when running the
-      NSH command ifconfig over Telnet.  In that case the function netdev_foreach
-      takes the network device semaphore, but so does the telnet logic causing
-      the deadlock.
-    * arch/arm/src/stm32/stm32_pm*.c: Add basic STM32 power management logic
-      that will eventually be used to implement low power states.
-    * arch/arm/src/stm32/stm32f*0xx_rcc.c:  In order to use CAN2, both CAN1 and
-      CAN2 clocking must be enabled.
-    * arch/mips/src/pic32mx/picm32mx-usbdev.c:  Several stall-related fixes so that
-      the USB device driver can used the the mass storage class (which does a LOT
-      of stalling as part of its normal protocol).  The PIC32 USB Mass Storage
-      device is, however, still non-functional when debug is OFF.
-    * include/nuttx/fs: Move all file-system related files from include/nuttx to
-      include/nuttx/fs.
-    * include/nuttx/serial: Move all serial-driver related files from include/nuttx to
-      include/nuttx/serial.
-    * include/nuttx/clock.h and sched/clock_initialize.c:  Add a new OS interface
-      called clock_sychronize() that can be used to re-synchronize the NuttX
-      system time with a hardware RTC.  This function is called normally at power
-      up but may also need to be called when recovering from certain low-power
-      usage states where the system time is no longer accurate.
-    * arch/arm/src/calypso and arch/arm/include/calypso: Support for the TI "Calypso"
-      phone processor. Contributed by Denis Carilki and includes the work of Denis,
-      Alan Carvalho de Assis, and Stefan Richter.
-    * configs/compal_e88 and configs/compal_e99:  Support for Compal e88 and e99 phones

-      user NX server because of lack of use.
-    * graphics/nxconsole:  The NX text console is basically function (in multi-
-      user NX mode only).
-    * arch/arm/src/stm32/stm32_i2c.c: Correct a bug in the STM32 I2C driver.  The
-      behavior of I2C status bits seems to be different between F1 and F4.
-    * configs/stm3210e-eval/nxconsole:  New STM32 F1 configuration that runs the
-      NuttShell (NSH) within an NX window.
-    * graphics/nxconsole/nxcon_sem.c:  Add protection from re-entrance with debug
-      is enabled.

-    * graphics/nxconsole/nxcon_vt100.c:  Add add framework to support VT100 escape
-      sequences in NxConsole.
-    * fs/fs_read.c:  Fix read() return value for attempt to read from write-only

-    * graphics/nxconsole.c:  NxConsole now supports backspace and a cursor.
-    * Kconfig and arch/sim/Kconfig:  Beginnings of support for a NuttX
-      configuration tool.  Currently using the kconfig parser 'kconfig-frontend'

-    * */Kconfig:  Added skeleton Kconfig files to all directories that
-      may need them.
-    * include/nuttx/math.h:  Moved include/math.h to include/nuttx/math.h
-      because it conflicts too often with the system math.h (and people aren't
-      inclined to read the documentation on how to handle this).  Now, if
-      CONFIG_ARCH_MATH_H=y is defined, the top-level makefile will copy
-      the redirecting math.h header file from include/nuttx/math.h to
-      include/math.h.  So for the architectures that define CONFIG_ARCH_MATH_H=y,
-      include/math.h will be in place as it was before; for the architectures

-      Extend the USB device side interface so that EP0 OUT data can be passed
-      with OUT SETUP requests.

+      no NX component should try to read from the underlying graphic device (LCD
+      or other).
+    * configs/stm3240g-eval/src/up_stmpe11.c:  Add board-specific support for the
+      the STMPE11 I/O expander on the STM3240G-EVAL board.  Verfied that the
+      STM3240G-EVAL touchscreen is now fully functional.
+    * include/cxx/cfcntl:  Added std:: header file.
+    * graphics/nxbe/nxbe_filltrapezoid.c and graphics/nxglib/fb/nxglib_filltrapezoid.c:
+      Fix several errors in the trapezoid fill logic.
+    * include/nuttx/input/touchscreen.h, configs/hymini-stm32, configs/stm3240g-evel,
+    * configs/sam3u-ek, configs/sim, arch/sim/src/up_touchscreen.c, and
+      apps/examples/touchscreen: Standardize the board-specific, touchscreen
+      initialization interfaces.
+    * drivers/input/stmpe11_base.c and configs/stm3240g-eval:  The STMPE11-based
+      touchscreen seems to work better with edge (vs. level) interrupts
+    * drivers/input/stmpe11_tsc.c:  Fix some status checks so that the touchscreen
+      interrupt handling logic does not read data if the fifo is not at the
+      threshold level.
+    * include/nuttx/wqueue.h: Add macro work_available() to determine if the
+      previously scheduled work has completed.
+    * drivers/stmpe11_tsc.c:  Correct errors: (1) Since all interrupt logic is done on
+      the worker thread, disabling interrupts does not provide protected; Need to
+      disable pre-emption.  (2) Fix handling of touch ID and (2) add some logic to
+      prevent certain kinds of data overrun.
+    * include/nx/nxtk.h and graphics/nx/nxtk/nxtk_internal.h:  Move setting
+      of configuration defaults from the internal header file to a place where
+      other logic can use the defaults.
+    * graphics/nxtk/nxtk_events.c:  Fixed an important but in the logic that
+      translates the mouse/touchscreen position data for framed windows and toolbars.
+    * drivers/input/stmpe11_tsc.c, tsc2007.c, and ads7843e.c:  Need to keep track of
+      when if positional data is valid.  When the touch is released, the X/Y position
+      of the release must be the same as the X/Y position of the last touch (se that
+      the release occurs in the same window as the last touch).
+    * graphics/nxtk/nxtk_events.c:  Fix an error in mouse/touchscreen input logic:
+      Was autoraising the window AFTER processing the mouse press.  This raises havoc
+      if the result of processing the mouse click was to raise some other window!
+    * graphics/nxtk/nxtk_events.c:  I had to disable the whole autoraise feature
+      for multi-user case because it does not work correctly.  In a scenario where (1) there
+      are multiple queued touchscreen events for the same window and (2) the result of the
+      first input was to switch windows, then the autoraise implementation will cause the
+      window to revert to the previous window.  Not good behavior.
+    * sched/sched_mergepending.c:  Add task switching instrumentation.  There is a case
+      here where instrumentation was missing.  Contributed by Petri Tanskanen.
+    * CONFIG_STMPE11_THRESHX, CONFIG_STMPE11_THRESHX, and drivers/stmpe11_tsc.c:  Add some
+      thresholding controls to all slow down processing of touchscreen samples.
+      This is a problem with NX in multi-user mode:  touchscreen data gets sent
+      via a message and when the message queue gets full the sender blocks and
+      touch events are lost.  Basic data overrun.  The badly effects touchscreen
+      human factors.
+    * include/sched.h:  Fix a typo (missing semicolon) in prototype of on_exit();
+    * sched/on_exit.c and include/nuttx/sched.h:  Fix some old typos that caused
+      compilation errors when CONFIG_SCHED_ONEXIT is defined.
+    * configs/stm3240g-eval/nxwm/defconfig:  The default NxWM now uses the STMPE11
+      touchscreen.
+    * include/cxx/csched: Added
+    * graphic/nxmu/nxmu_sendserver.c, nxmu_sendwindow.c, and nxmu_sendclient.c:
+      Refactor NX messaging logic in preparation for a new message control
+      feature.
+    * graphics/nxtk, graphics/nxmu, include/nuttx/nx:  Add a new window communication
+      to support blocking and flushing of client window messages.  If there are
+      stale, queue window messages at the time that a window is destroyed, very bad
+      things happen.

+apps-6.18 2012-05-19 Gregory Nutt &lt;gnutt@nuttx.org&gt;
+
+    * Kconfig:  Continued Kconfig file updates (no longer tracking on a per-file
+      basis in the ChangeLog)
+    * apps/examples/watchdog:  Add a watchdog timer example.
+    * apps/examples/tiff:  Fix wrong path used for temporary file.
+    * apps/examples/touchscreen:  Standardize the board-specific, touchscreen
+      initialization interfaces.
