-    * arch/arm/src/lpc17xx/chip.h:  Fix some chip memory configuration errors
-      for the LPC1764, LPC1756, and LPC1754 (submitted by Li Zhuoy (Lzzy))
-    * arch/arm/src/lpc17xx/lpc17_can.h:  Revised CAN driver submitted by
-       Li Zhuoy (Lzzy).  The driver now supports both CAN1 and CAN2.
-    * arch/arm/sim/up_lcd.c: Add a simulated LCD driver.
-    * 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/kwikstik-k40:
-      Add a directory structure to support the port to the Kinetis KwikStik-K40.
-      There is no real substance in the initial check-in; only the directory
-      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.
+    * arch/arm/src/kinetis/kinetis_sdhc.c: SDHC driver for Kinetis parts.
+      Initially check-in is just a crude port of the STM32 SDIO driver.
+      Much more work is needed.
+    * graphics/, include/nuttx/nx:  Add new NX interfaces for drawing
+      circles -- both circular outlines and filled circles.
+    * graphic/nxglib/nxglib_spitline.c:  Add a "fudge factor" that eliminates
+      some problems for rendering nearly horizontal, wide lines.  Hmm...
+      but I suspect this fudge factor also leads to new problems rendering
+      very thin, nearly horizontal lines.  More tuning is needed.
+    * drivers/analog, include/nuttx/analog, arch/arch/src/lpcxx:  (1) Add
+      updates to the ADS1255 driver, (2) fix errors from my last merge (sorry),
+      (3) Add DAC infrastructure, (4) add AD5410 DAC driver, and (5) add
+      LPC17xx ADC and DAC drivers.  All contributed by Li Zhuoyi (Lzyy).
+    * tools/mkexport.sh:  Extended the script that implements the top-level
+      'make export' logic.  The script now also finds and bundles up all of
+      the architecture-specific header files as well.
+    * drivers/arch/arm/src/stm32/stm32_i2c.c:  Add a reset to the I2C
+      initialization logic to prevent spurious interrupts when the I2C
+      interrupts are enabled (submitted by Uros Platise).
+    * Scripts/makefiles/documents.  Several adjustments, corrections and
+      typo fixes so that NuttX will build correctly on FreeBSD using the
+      ASH shell (submitted by Kurt Lidl).
+    * drivers/mtd/flash_eraseall.c:  Add a callable function that accepts
+      the path to a block driver and then erases the underlying FLASH memory
+      (assuming that the block driver is an MTD driver wrapped in the FTL
+      layer).  Hmmm... this is probably not the best long term solution;
+      flash_eraseall() should be a user-callable function that operates
+      one driver interfaces; not an internal, OS function that operates
+      on directly on block drivers.
+    * drivers/bch:  Fixed some important bugs in the BCH driver (noted by
+      Li Zhuoyi (Lzyy)).  This would have effected any large reads or writes
+      (larger than the hardware sector size).
+    * arch/*/src/Makefile:  Use of -print-libgcc-file-name to get path to
+      libgcc.a may select the wrong libgcc.a if a multilib toolchain (like
+      CodeSourcery) is used. This can be a serious problem and can cause
+      crashes on Cortex-M3 if the ARM libgcc is used, for example.  The fix 
+      is to include ARCHCPUFLAGS on the gcc command line when asking it to
+      -print-libgcc-file-name.
+    * lib/time/lib_gmtimer.c:  Correct several calculations that could lead
+      to errors in dates.
+    * drivers/pm: Add the beginnings of a NuttX power management sub-system.
+    * arch/arm/src/stm32/stm32_irq.c:  Fix a error introduced in 6.8.
+      Timeout calculation uses clock_settime() instead of clock_gettime().
+      Pretty gross error, but actually it works with the side effect of setting
+      a bad time.
+    * drivers/mtd/at24xx.c: Driver for I2C-based at24cxx EEPROM submitted by
+      Li Zhuoyi (Lzyy).
+    * arch/arm/src/lpc17xx/lpc17_i2c.c: I2C driver for the NXP LPC17xx family
+      submitted by Li Zhuoyi (Lzyy)
+    * arch/arm/src/stm32_i2c.c:  Correct two issues with the STM32 I2C driver:
+      (1) Clocking needs to be based on PCLK1, not HCLK and fast speed settings
+      need some additional bits; and (2) Correct a hang that will occur on
+      I2C1 if FSMC is also enabled.
+    * drivers/sensors/lm75.c and include/nuttx/sensors/lm75.h:  Add an LM-75
+      temperature sensor driver.
+    * configs/stm3210e-eval/src/up_lm75.c:  Add support for the LM-75 on the
+      STMicro STM3210E-EVAL board.
+    * sched/clock_gettime.c:  Correct an error in the tv_nsec calculation
+      that happens only config CONFIG_RTC is enabled.
+    * arch/arm/src/stm32/stm32_i2c.c:  Correct some bugs related to waiting
+      to the I2C STOP condition to be cleared.

+NuttX-6.9
+^^^^^^^^^
+
+The 76th release of NuttX, Version 6.8, was made on September 11, 2011
+and is available for download from the SourceForge website.  Note
+that release consists of two tarballs:  nuttx-6.9.tar.gz and
