-    * Makefile:  Added a export target that will bundle up all of the NuttX
-      libraries, header files, and the startup object into an export-able
-      tarball.
-    * arch/arm/src/lpc17xx/lpc17_can.h:  Correct some typos in the CAN
-      register definitions.
-    * drivers/serial/serialirq.c:  Correct an error that can occur if the
-      serial RX buffer becomes full.  Data is now discarded in that case;
-      before, leaving data in the hardware would cause infinite interrupts
-      one most MCUs since you must read the data in order to clear the
-      interrupt.
-    * arch/arm/src/lpc17xx/lpc17_can.c:  Added a CAN driver contributed by
-      Li Zhuoyi (Lzyy).
-    * include/stddefs.h and sys/types:  Added type wchar_t.
-    * fs/fat/fat_fat32dirent.c:  Move all FAT directory operations to this
-      new file; Implement VFAT long file name support.
-    * fs/fat/fat_fat32dirent.c:  The configuration CONFIG_FAT_LCNAMES has
-      been around for some time but never tested until now.  This setting
-      will mimic the NT 8.3 file name behavior:  File names or extensions 
-      may be all upper or all lower case (but not mixed).  If
-      CONFIG_FAT_LCNAMES is not selected, all filenames are strictly upper
-      case.
-    * configs/stm3210e-eval/nsh2:  Console is back on UART1; Added
-      examplex/nx as an NSH "built-in" command as a demonstration.
-    * fs/fat/fs_fat32dirent.c:  Fix an important bug in the directory
-      allocation (fat_allocatedirentry()).  I looks like it could be
-      initializing the wrong sectors! NOTE:  This function was in
-      fs_fat32utils.c in earlier releases.
-    * arch/arm/src/stm32_sdio.c: Correct an important DMA-related bug;
-      SDIO transfer completion events and DMA completion eventes were
-      not being coordinated correctly.
-    * configs/stm3210e-eval/nsh2: Enable FAT long file name support
-    * sched/sem_timedwait.c: Add the standard sem_timedwait() interface.
-    * graphics/nxfonts/nxfonts_getfont.c, nxfonts_bitmap.c,
-      Makefile.source, and include/nuttx/nxfonts.h: Support for multiple
-      fonts included.  A new interface, nxf_getfonthandle() takes a font
-      ID and returns a handle that is now used at all other font interfaces
-      to specify which of the multiple fonts to use.
-    * arch/arm/src/lpc17xx/lpc17_syscon.h: Fix typo (reported by Li Zhuoyi).
-    * configs/stm3210e-eval/nsh2: Extended to support two new commands:
-      'msconn' will connect the USB mass storage device; 'msdis' will
-      disconnect the USB storage device.
-    * tools/bdf-converter.c.  This C file is used to build the bdf-converter
-      program.  The bdf-converter program be used to convert fonts in Bitmap
-      Distribution Format (BDF) into fonts that can be used in the NX graphics
-      system.
-    * include/nuttx/nx:  Move all NX header files from include/nuttx to 
-      include/nuttx/nx.
-    * drivers/usbdev/usbdev_usbstorage.c and arch/arm/src/stm32/stm32_usbdev.c:
-      Correct a memory leak when the USB mass storage driver is connected and
-      then disconnected from the target.  The write requests were not being
-      freed.  NOTE that the unregister logic in the STM32 needed to call
-      stm32_reset() in order to return the write requests to the USB mass
-      storage driver; it is possible that a similar but could exist for other
-      architectures.
-    * graphics/nxfonts/nxfonts_*.h:  Add serveral more new fonts
-    * arch/z80/src/ez80/ez80_serial.c: Fix some errors in serial driver
-      setup for UART1 (submitted by Paul Osmialowski).
-    * drivers/input/tsc2007.c and include/nuttx/input/*:  Add a generic NuttX
-      touchscreen interface.  Add a driver for the TI TSC2007 touchscreen
-      controller.
-    * graphics/nxglib/lcd and fb:  Add low level routines to set single pixels.
-    * lib/math/lib_b16atan2.c:  Add a fixed precision atan2() function
-    * graphics/nxglib/nxglib_splitline.c: Add logic to divide a wide line into
-      trapezoidal components.
-    * graphics/nxmu/nx_drawline.c, graphics/nxsu/nx_drawline.c,
-      graphics/nxtk/nxtk_drawlinewindow.c, graphics/nxtk/nxtk_drawlinetoolbar.c:
-      Add new line drawing interfaces (untested).

+    * configs/stm3210e-eval/nxlines:  Added a configuration to build
+      examples/nxlines.
+    * arch/graphics: Used apps/examples/nxlines to (finally) verify the NX
+      trapezoid drawing functions and (wide) line drawing functions.
+    * arch/rgmp and configs/rgmp.  Yu Qiang has ported RGMP to the OMAP4430 (arm)
+      pandaboard and release the new RGMP 0.3 version. The main changes are: (1)
+      Separate configs/rgmp/x86 and configs/rgmp/arm configuration directory, and
+      (2) Extract architecture dependent code in arch/rgmp/include and
+      arch/rgmp/src into corresponding x86/ and arm/ directories.
+    * arch/arm/src/kinetis, arch/arm/include/kinetis, configs/kwikstick-k40:

+      structure and skeleton files (Code complete on 8/15/11).
+    * arch/arm/include/armv7-m, arch/arm/src/armv7-m, etc.: Rename all cortexm3
+      directories and files to armv7-m; Change name of of all CORTEXM3 constants
+      to ARMV7M.  This is a major namespace change needed to cleanly support the
+      ARM Cortex-M4 which is also in the ARMv7 M Series (specifically, ARMv7E-M).
+    * sched/sig_initialize.c, sig_received.c, and mq_waitirq.c.  Fixed several
+      critical bugs related to signal handling initialization and for signals
+      the wake up tasks that are waiting to send or receive message queues.  In
+      the first two files, errors would prevent proper allocation of signal-related
+      structures from interrupt handlers.  In the second, there was missing
+      "clean-up" logic after a signal occurred, leaving the message queue in
+      a bad state and resulting in PANICs.  All are important.  (submitted by
+      hkwilton).
+    * arch/arm/src/kinetis:  Added header files defining all Kinetis registers
+      and bit fields within all Kinetis registers.
+    * configs/twr-k60n512:  Add support for the Kinetis K60 Tower board
+      (TWR-K60N512).
+    * drivers/can.c:  Fixe a semaphore overflow problem in the CAN driver
+      (reported by Li Zhouy (Lzzy)).
+    * 8/18/2011: The basic port to the FreeScale Kinetics TWR-K60N512 board is
+      now functional.
+    * confgs/twr-k60n512: Add Kinetics TWR-K60N512 NSH configuration.
+    * drivers/analog and include/nuttx/analog: Add ADC driver infrastructure
+      and TI ADS1255 driver developed and submitted by Li Zhouy (Lzzy)).
+    * arch/arm/stm32/stm32_sdio.h and drivers/mmcsd/mmcsd.c:  Add logic to
+      multiplex usage of the GPIO pins (contributed by Uros Platise).
+    * configs/twr-k60n512/nsh:  Added and verified a NuttShell (NSH)
+      configuration for the Freescale, Kinetis TWR-K60N512 board.
