+^^^^^^^^^
+
+The 74th release of NuttX, Version 6.7, was made on August 2, 2011 and is
+available for download from the SourceForge website.  Note that release
+consists of two tarballs:  nuttx-6.7.tar.gz and apps-6.7.tar.gz.  Both
+may be needed (see the top-level nuttx/README.txt file for build
+information).  Changes in this release are summarized below:
+
+    * New OS APIs: Add the standard sem_timedwait() interface.
+    * FAT File System:  Adds (optional) support for VFAT long file names.
+    * USB:  Now the mass storage device can be connected when needed and
+      disconnected when not needed (or re-connected as a different kind of
+      device).
+    * Touchscreen Support:  Defined a new NuttX touchscreen interface.
+      Added a driver for the TI TSC2007 touchscreen controller chip.
+    * NX Fonts:  Add support for multiple fonts; developed a tool to
+      convert open source fonts into NuttX format; Converted and installed
+      nine new, high quality fontsets.
+    * NX Graphics: Add new NX APIs to support drawing of wide lines in any
+      orientation.  Added new low level routines to set individual pixel
+      more efficiently.
+    * Build system:  Added a export target that will bundle up all of the
+      NuttX libraries, header files, and the startup object into an export-
+      able tarball.
+    * LPC17xx: A CAN driver was contributed by Li Zhuoyi (Lzyy).
+    * STM32: New NX-related configurations to excercise text and graphic image
+      displays.
+    * C Library:  Added a fixed precision atan2() math function.
+    * Bugfixes:  Serial RX overrun error, FAT upper/lower NT 8.3 name
+      handling fixed.  FAT directory allocation and initialization bug.
+      STM32 SDIO DMA race condition bug.  eZ80 UART1 serial driver errors
