+^^^^^^^^^
+
+The 73rd release of NuttX, Version 6.6, was made on July 11, 2011 and is
+available for download from the SourceForge website.  The 6.6 release
+adds several smaller featurs but is mostly a bugfix release.
+
+Bugfixes include
+
+    * Fixed several NX Graphics bugs: Rendering fonts at >8 bits-per-pixel,
+      graphics move logic, and display artifacts that appear when a window
+      is closed.
+    * Corrections to the USB host mass storage class driver
+    * STM32 bugfixes: serial driver, GPIO interrupt handling
+    * LPC17xx: Changes for a success compilation with no console.
+    * Corrections to the Teensy AT90USB SD driver
+    * Changes for a clean compilation under the ZDS-II toolchain.
+
+Minor features:
+
+    * Add logic to extract printf strings from FLASH (but there are still printf
+      issues for that target)
+    * Added a configuration for the Sure Electronics PIC32MX board.  However,
+      higher priority tasks have stopped work on that configuration.
+    * Added several new configurations for the STMicro STM3210E-EVAL board.
+    * Added support for the STM3210E-EVAL board: (1) LCD in either landscape or
+      portrait mode, and (2) interrupting buttons.
+    * Added a configuration option to use different serial ports for debug
+      and for the NSH serial console (there are some issues with CR-LF
+      expansion and character echo if NSH is not run on the console).
+    * Standardized the button press and button interrupt interfaces so that they
+      are common across all boards.
+    * Added a new graphics example that 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.
+    * Added ARM stack checking logic.
+
+See the ChangeLog for a detailed description of these changes.
