+nuttx-6.0
+^^^^^^^^^
+
+The 67th release of NuttX, Version 6.0, was made on March 21, 2011 and is
+available for download from the SourceForge website.  The version number of
+this release was bumped from 5.19 to 6.0.  A change in the major revision
+number is used to reflect an incompatibility with previous versions.  In
+this release, the NuttX core OS functionality has been separated from NuttX
+application-related functionality.  These are provided as separate tarballs:
+
+    * nuttx-6.0.tar.gz, and
+    * apps-6.0.tar.gz
+
+The purpose of this separation is both to better organize and modularize the
+NuttX source tree, but also to provide better support for incorporation of
+end-user applications with Nuttx.
+
+The incompatibily results from the changes to the board configuration logic
+needed to supported the separable application.  The major changes to the
+configuration include:
+
+    * CONFIG_APPS_DIR - This should not be set.  The default is ../apps.  This
+      should only be set if you have a custom, product-specific application
+      directory in some different location.
+
+    * appconfig - Each board configuration now requires a new file called 
+      'appconfig.'  As its name suggests, this file provides new configuration
+      information needed by the logic in ../apps.
+
+In addition to this major reorganization in the directory structure, this
+release also includes some important extensions to existing features and some
+important bugfixes.  These include:
+
+    * The SLIP driver was been well debugged and significantly re-designed.
+      Now you can have an Ethernet connection to you board even if you have
+      no Ethernet hardware.  How cool is that?
+
+    * The QEMU i486 port is now functional.  It has also been reported to
+      work on the Bifferboard (see http://bifferos.bizhat.com/).
+
+    * And extensions to the uIP driver interface, and
+
+    * Bug fixes to fopen() and STM32 GPIO configuration
+
+Please see the ChangeLog for details.
