-
-    * drivers/mtd/ramtron.c, net/net_checksd.c, fs/fs_fdopen.c, and include/nuttx/mii.h:
-      Several structural changes made to get a clean compile under the ez80 ZDS-II
-      toolchain (no design changes).
-    * drivers/usbhost/usbhost_storage.c: Incorpated bugfixes reported by Sheref H.
-      Younan:  (1) Read capacity logic read largest block, not the number of blocks
-      and was, therefore, off by one, and (2) Some devices stall of get Max LUN request
-      if they support only a single LUN.  Logic now assumes a single LUN if the get
-      Max LUN request fails.
-    * include/nuttx/arch.h, lib/stdio/lib_libvsprintf.c, lib/stdio/lib_fputs.c: Add
-      a new configuration option to support extracting strings from FLASH or EEPROM
-      or other memories where the string data cannot be accessed by simply de-referencing
-      a string pointer.
-    * arch/sim/src/up_romgetc.c: Used to test the basic logic to access strings
-      without directly de-referencing a string pointer.
-    * arch/avr/src/avr/up_romget.c: Used to access strings that lie in the first
-      64Kb of FLASH (But I still haven't figured out how to get strings to reside in
-      FLASH without using the PROGMEM attribute).
-    * configs/teensy/src/up_spi.c: Correct reading of SD CD and WP pins (was reading
-      the wrong register.  AVR SPI now appears to be functional.
-    * arch/avr/src/at90usb/at90usb_usbdev.c: Correct USB initialization.  Interrupts
-      were being enabled BEFORE the interrupt handler was attached.
-    * configs/sure-pic32mx:  Add a configuration for the Sure Electronics, &quot;Advanced USB
-      Storage Demo Board,&quot; Model DB-DP11215 (http://www.sureelectronics.net/goods.php?id=1168).
-      This board features the MicroChip PIC32MX440F512H MCU. (Untested on initial
-      check-in).
-    * configs/stm3210e-eval/nsh2:  Add another NSH configuration for the STM32 with
-      some different properties.
-    * CONFIG_NSH_CONDEV:  Add a configuration option to allow using a different character
-      device (such a a different UART) for the NSH interface.  This allows, for example,
-      debug output to come from the console device while using another device for NSH.
-      There are some issues on initial check-in:  NuttX doesn't have termios and the
-      console device has special properties that make using NSH awkward.  Examples:
-      No CR-LF expansion, no character echoing, no command line editting.
-    * arch/arm/src/stm32/stm32_lowputc.c and stm32_serial.c.  Correct seversl bugs
-      involving serial port configuration.  These bugs are only critical if you
-      are trying to using multiple UARTs on STM32.
-    * configs/stm3210e-eval/src/up_lcd.c:  Add a driver for the STM3210E-EVAL's LCD.
-    * configs/stm3210e-eval/nx:  Add NX configuration for the STM3210E-EVAL.
-    * configs/nuttx/arch.h (and arch/arm/src/stm32, configs/*/src/up_buttons.c):
-      Standardize interfaces exported for button support and button interrupts.
-    * configs/stm3210e-eval/src/up_buttons.c:  Add interrupting button support.
-      Also fixes a few errors in STM3210E-EVAL button decoding.
-    * configs/stm3210e-eval/buttons: Add a configuration to exercise STM3210E-EVAL
-      buttons.
-    * arch/arm/src/stm32/stm32_gpio.c:  GPIO interrupt handling for pin
-      numbers were being aliased:  5-9 together and 10-15 together.  Extended
-      the logic to peform decoding of GPIO interrupts and unique dispatching
-      for all 16 pins.
-    * configs/stm3210e-eval/nxtext: Add a configuration for the apps/examples/nxtext
-      example.  This example focuses on placing text on the background while
-      pop-up windows occur.  Text should continue to update normally with or without
-      the popup windows present.
-    * arch/arm/src/common/up_checkstack.c:  ARM stack overflow checking submitted
-      by Hal Glenn.
-    * arch/arm/src/lpc17xx: Changes to compile successfully with no serial console
-      (also submitted by Hal Glenn).
-    * graphics/nxfonts/nxfonts_convert.c:  Fixed a critical bug that caused
-      when renderer some fonts with bits-per-pixel &gt 8
-    * graphics/nxbe/nxbe_move.c: Fixed an error in the graphics move logic (This
-      was a previously untested interface).  Basically, there is some confusion
-      between use of (x,y) as a relative offset or as an absolute position.
-    * graphics/nxbe/nxbe_close.c:  Fixed an important graphics system bug:
-      When a window is closed, the display was not being updated.  The old
-      window graphic was left on the display for a time.

+consists of two tarballs:  nuttx-6.7.tar.gz and apps-6.7.tar.gz.  Both
