+NxWidgets-1.1
+=============
+
+The 2nd release of the NxWidgets package as made on May 19, 2012.  The
+headline new feature in this release is:
+
+* NxWM, the tiny window manager based on NX and NxWidgets. NxWM is true
+  multiple window manager but only one window is displayed at a time.
+  This simplification helps performance on LCD based products (in the
+  same way that a tiled window manager helps) and also makes the best
+  use of small displays.  It is awkward from a human factors point-of-view
+  trying to manage multiple windows on a small display.
+
+  The window manager consists of a task bar with icons representing the
+  running tasks.  If you touch the task's icon, it comes to the top.  Each
+  window has a toolbar with (1) a title, (2) a minimize button, and (3) a
+  stop application button using the standard icons for these things. User
+  input via a touchscreen or mouse and keyboard is supported.
+
+  There is always a start window that is available in the task bar.  When
+  you touch the start window icon, it brings up the start window containing
+  icons representing all of the available applications.  If you touch an
+  icon in the start window, it will be started and added to the task bar.
+
+  There is a base class that defines an add-on application and an
+  interface that supports incorporation of new application.  The only
+  application that is provided is NxConsole.  This is an  NSH session
+  running in a window.  You should be able to select the NX icon in the start
+  menu and create as many NSH sessions in windows as you want. (keybard input
+  still comes through serial).
+
+  This initial realease of NxWM should be considered an alpha release.
+  All know issues are listed in the top-level TODO list.
+
+Other important new features include:
+
+* NxWidgets::IBitmap and NxWidgets::CRlePalettBitmap:  Extended to
+  support different color look-up-tables (LUTs).  This allows images
+  to be highlighted when touched, for example.
+* NxWidgets::CImage:  Extended to support button-like behavior.  CImage
+  widgets now work well as touchable icons.
+* NxWidgets::CWidgetControl:  Add a semaphore to force clients to wait if the
+  size or position of the window is not yet known (multi-user mode only).
+  Enabled and verified creation of framed windows.
+* NxWidgets::CWindowEventHandler and NxWidgets::CWindowEventHandler:  Add
+  support for getting callbacks for window events.
+* DOxygen documentation support.  Contributed by Jose Pablo Carballo.
+
+An effort is underway to simplify NxWidgets and reduce its memory footprint:
+
+* NxWidgets::CNxWidget: Removed support for "shelving" widgets, reference
+  constants, and close types. Remove all support for widgets in a "vertical"
+  hierarchy.  Now widgets exist in a flat, two-dimensional space and should
+  not overlap.  Removed built-in modal loops.
+
+Bug fixes include changes to the following (see the ChangeLog for details):
+
+* NxWidgets::CRlePalettBitmap, NxWidgets::CRlePalettBitmap,
+  NxWidgets::CGraphicsPort, NxWidgets::CWidgetControl

+  Description: During the initialization of the display, the basic frame of the

+               frame.  This is a consequence of how NX creates windows:  The

+               are being created. The solution would be to add some disable

+
+  Title:       MISSING TOUCH RELEASE
+  Description: Using the STM3240G-EVAL board with the STMPE11 touchscreen, you
+               will find that there are occasional missing indications of when
+               you release a icon.  This is believed to be a data overrun in the
+               STPMPE11 data path.  The STMPE11 generates data a very high
+               rate and it is believe that it sometimes misses the interrupt
+               that indicates that the touch is released.  The symptom in NxWM
+               is that you touch an icon, it is highlighted but when you release
+               the touch nothing happens.  The icon stays highlighted.  Touching
+               the icon again usually works around this problem.

+  <li><b>STM32</b>.
-    Added a new interface call <code>clock_synchronize()</code>. 
+    Add support for the STM32 IWDG and WWDG watchodog timers. 
-    This function will reload the system time from an RTC and is required when the system re-awakens from certain deep-sleep modes.

+    serial driver now uses circular DMA to improve Rx performance (Contributed by Mike Smith).
   </li>
-  <li><b>Graphics</b>.
+  <li><b>STM3240G-EVAL Board</b>.
-    Add <i>NxConsole</i>.
+    Add support for the LCD and for the STMPE11 I/O Expander as a touchscreen controller.
-    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>.
+  <li><b>PIC32 Boards</b>.
-    Added an interface definition an &quot;upper half&quot; driver to support watchdog timers.

   </li>
-  <li><b>Calypso</b>.
+  <li><b>NX</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.
+    Framed windows are now draw in three colors instead of just two.
-    This includes configurations for the Compal e88 and e99 phones.
+    Numerous other extensions needed to support NxWM (see the ChangeLog for details).
   </li>
-  <li><b>USB Device Interface</b>.
+  <li><b>Library</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.
+    Add <code>prctl()</code> command that can be used to setting and getting the names of threads.
-  </li>
+    This (plus several other improvements and bug fixes) are part of a larger effort to improve task monitoring capabilities.
-  <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>
-  <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>
-  <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>
-  <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>
-  <li><b>Tools</b>.
-    Added <code>tools/cmpconfig.c</code>, a tool for comparing two configuration files.

     * Build System:  Reordered the link command line to account for new
       versions of libgcc.a that require symbols from the application
       (abort()).
+
+NuttX-6.18
+^^^^^^^^^^
+
+The 85th release of NuttX, Version 6.18, was made on May 19, 2012,
+and is available for download from the SourceForge website.  Note
+that release consists of two tarballs:  nuttx-6.18.tar.gz and
+apps-6.18.tar.gz.  Both may be needed (see the top-level nuttx/README.txt
+file for build information).
+
+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.
+
+New features and extended functionality:
+
+    * Drivers.  Added a watchdog timer driver infrastructure.  Add general
+      support for STMicro STMPE11 I/O Expander/touchscreen device.
+
+    * STM32. 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).
+
+    * STM3240G-EVAL Board.  Add support for the LCD and for the STMPE11
+      I/O Expander as a touchscreen controller.
+
+    * PIC32 Boards.  Board support for the Mikroelektronika PIC32MX7
+      Multimedia Board (MMB) and for the Sparkfun UBW32 PIC32 board.
+
+    * NX. Framed windows are now draw in three colors instead of just two.
+      Numerous other extensions needed to support NxWM (see the ChangeLog
+      for details).
+
+    * Library. Add prctl() 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.
+
+Work in progress.  This release includes some partially completed
+work that is still not ready for prime time.
+
+    * NFS Client. Work is progressing on support for an NFS client
+      file system.   This is a port of the BSD NFS client file system
+      that is being done by Jose Pablo Rojas V.
+
+    * Automated Configuration. Automated configuration based on the
+      kconfig-frontends tool is being incorporated into the build
+      system.  The configuration is still not complete enough for
+      general use in this release.
+
+    * STM32 Drivers. Added files that will (eventually) hold an STM32
+      OTG FS host driver.  This is still a work in progress.
+
+Bugfixes (see the change log for details) :
+
+    * sched_setscheduler() return value (Contributed by Richard Cochran).
+
+    * stdio. Ignore CONFIG_STDIO_LINEBUFFER if the file was opened in binary mode.
+
+    * fopen(). Correct an error in parsing open mode string.
+
+    * serial driver. Improved performance be reducing the amount of time
+      that Rx interrupts are disabled.
+
+    * recvfrom(). Fix a compilation problem.
+
+    * CDC/ACM device driver. Fix an infinite loop that occurs when the serial
+      device is unregistered.
+
+    * STM32 OTG FS device driver. Numerous fixes and the driver is partially
+      functional but there are still some issues that become apparent when
+      debug output is disabled.
+
+    * fcntl(). Always returned zero on success; however, some fcntl commands
+      need to return non-zero values on success.
+
+    * graphics:  Many multi-use mode fixes added to support NxWM (see the
+      ChangeLog for details).  Auto-raise is temporarily disabled in multi-
+      user mode because it causes some problems with NxWM.
+
+    * on_exit():  Fix compilation errors if CONFIG_SCHED_ONEXIT is enabled.
