+  The 70<sup>th</sup> release of NuttX, Version 6.3, was made on May 15, 2011 and is available for download from the
   <a href="http://sourceforge.net/projects/nuttx/files/">SourceForge</a> website.

 <p>
+  The release of NuttX-6.3 follows only a nines days after the release of version 6.2.
+  This special back-to-back release was made so that the current released version of
+  NuttX will correspond to the initial release from the RGMP project.
+</p>
+<p>
+  This release adds architecture support and build configuration for RGMP.
+  RGMP is a project for running GPOS and RTOS simultaneously on multi-processor platforms.
+  See the <a href="http://rgmp.sourceforge.net/wiki/index.php/Main_Page">RGMP Wiki</a> for further information about RGMP.
+</p>
+<p>
+  This release also includes support for STM32 FLASH, build improvements, and initial, incomplete support for the MicroChip PIC32MX MCU.
+  Bug fixes are included for some build problems, USB host class driver error handling, NX graphics color mapping, and problems with C standard I/O buffer flushing.
+  See the ChangeLog for further details.

+<p>
+  Release notes for version 6.2 are retained because they are still relevant.

+             Current Status: I think I have a hardware problem with my serial port setup.
+             There is a good chance that the NSH port is complete and functional, but I am not yet able to demonstrate that.
+             At present, I get nothing coming in the serial RXD line (probably because the pins are configured wrong or I have the MAX232 connected wrong).

+         The basic, port (including the verified apps/examples/ostest configuration) was be released in NuttX-5.13.

+nuttx-6.3
+^^^^^^^^^
+
+The 70th release of NuttX follows only a nines days after the release of
+version 6.2.  It was released on May 15, 2011.  This special back-to-back
+release was made so that the current released version of NuttX will
+correspond to the initial release from the RGMP project.
+
+This release adds architecture support and build configuration for RGMP.
+RGMP is a project for running GPOS and RTOS simultaneously on multi-
+processor platforms. See http://rgmp.sourceforge.net/wiki/index.php/Main_Page
+for further information about RGMP.
+
+This release also includes support for STM32 FLASH, build improvements,
+and initial, incomplete support for the MicroChip PIC32MX MCU.  Bug fixes
+are included for some build problems, USB host class driver error handling,
+NX graphics color mapping, and problems with C standard I/O buffer flushing.
+See the ChangeLog for further details.
