 nuttx-6.7 2011-xx-xx Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
 
+    * 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:  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 &quot;built-in&quot; 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
+
 apps-6.7 2011-xx-xx Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
 
+    * apps/examples/nx and nxtext:  These examples can now be built as NSH
+      &quot;built-in&quot; commands.
