       Much more 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 &quot;fudge factor&quot; that eliminates
+    * graphic/nxglib/nxglib_spitline.c:  Add a "fudge factor" that eliminates
       some problems for rendering nearly horizontal, wide lines.
+    * 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 interrups 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).
+    * 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.
 
 apps-6.9 2011-xx-xx Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
 
     * apps/examples/nxlines:  Extend the line drawing text to include drawing
       of circles.
+    * apps/system/i2c:  Add an I2C test tool that should help to bring up I2C
+      devices (when it is fully functional).
+    * apps/nshlib/nsh_timcmds.c:  Add the date command that can be used to
+      show or set the time (only if CONFIG_RTC is set).
