+nuttx-6.4
+^^^^^^^^^
 
+The 71st release of NuttX, Version 6.4, was made on June 6, 2011 and is
+available for download from the SourceForge website.  The 6.4 release
+includes several new features:
+
+    * A new, full-featured FTP client.  This client may be used as a library
+      for automated FTP or via an FTP client shell.  The FTP shell supports
+      the following commands: cd, chmod, get, help, idle, login, ls, quit,
+      mkdir, noop, put, pwd, rename, rhelp, rm, rmdir, size, time, and up.
+      A configuration is available for the NXP LPC17xx to demonstrate this
+      functionality.
+    * A functional C1101 wireless driver (contributed by Uros Platise)
+    * A PCI-based E1000 Ethernet driver (contributed by Yu Qiang)
+    * New C library functions: inet_addr() (contributed by Yu Qiang),
+      strndup(), asprintf()
+    * Reduced memory allocation overhead for MCUs with small heaps (<64Kb).
+    * fdopen() now works with socket descriptors allowing standard buffered
+      C functions to be used for network communications.
+    * The NSH ifconfig command can now be used to set or change the IP
+      address (contributed by Yu Qiang)
+
+This release also includes some completed but untest functionality.
+
+    * The MicroChip PIC32MX port is now code complete and ready to begin
+      testing.  Unfortunately, testing will be delayed due to tool issues.
+    * Support for the NXP LPC315x MCUs.
+
+Additional miscellaneous enhancements and bug fixes to task_delete(), recvfrom(), and other changes as noted in the ChangeLog.
