+The 65th release of NuttX, Version 5.18, was made on February 27, 2011 and is
+available for download from the SourceForge website.  This is first release from
+the new NuttX SVN repository.  This release is made primarily to keep the release
+tarball in synchronization with SVN.  Many smaller changes have been made as
+identified in the ChangeLog.  Headlines would include:
+
+    * Incorporate several important uIP patches -- including the well known
+      patch to handle missing SYNACK.
+    * The Freescale mc8s12ne64 port is code complete but testing has not yet
+      begun due to toolchain issues.  Added support for the Future Electronics
+      Group NE64 Badge board.
+    * Added support for a new STM32 board, the ISOTEL NetClamps VSN V1.2 ready2go
+      sensor network platform.  This board is based on a STM32F103RET6 and
+      includes some interesting power saving/clock control extensions.
+    * USB host support expanded to handle vendor specific USB devices.
+    * Incorporated the LUFA HID parser.
+    * Various bugfix as detailed in the ChangeLog
