+    * mm/:  Added support for CONFIG_MM_SMALL. Each memory allocation has a
+      small allocation overhead.  The size of that overhead is normally
+      determined by the "width" of the address support by the MCU.  MCUs
+      that support 16-bit addressability have smaller overhead than devices

+      that support 32-bit addressability *but* have internal SRAM of size
+      less than or equal to 64Kb.  In this case, CONFIG_MM_SMALL can be
+      defined so that those MCUs will also benefit from the smaller, 16-
+      bit-based allocation overhead.
+    * lib/string/lib_strndup.c: Add standard strndup() library function.
+    * net/getsockname.c: Added standard getsockname() to return the local

+    * fd/fs_fdopen.c and net/net_checksd.c: Add support so that fdopen may
+      be used with socket descriptors.
+    * net/recvfrom.c: Fix an error found in receiving small files via FTP:
+      The small file is received a buffered in the readahead buffer, then the
+      socket is disconnected.  When the app calls recvfrom, the socket is
+      already disconnected and the buffered data is stranded.  Now, recvfrom
+      will continue to return success after the socket is disconnected until
+      the readahead buffer is drained.
+    * olimex-lp1766stk/ftpc/defconfig: Many configurations have the MTU 
+      (CONFIG_NET_BUFSIZE) set to very small numbers, less then the minimum
+      MTU size that must be supported -- 576. This can cause problems in
+      some networks:  CONFIG_NET_BUFSIZE should be set to at least 576 in
+      all defconfig files.  This has only been fixed in this defconfig file.
 
-    * arch/arm/src/lpc17xx: Correct some typos/bugs in configuration of LPC17xx
-      UART2 and UART3.
-    * nuttx/clock.h: Replace all references to the global variable g_system_timer
-      with clock_systemtimer() (currently just a macro that that returns g_system_timer).
-    * lib/string/strrch.c: Would fail if the searched-for character were the first
-      character in the string.
-    * tools/version.sh and mkversion.c: Tools to manage a NuttX version number
-      file
-    * sched/clock_getutc() and lib/time/lib_time.c: Add support for 1 second UTC
-      interface.
-    * net/net_dup2.c and include/nuttx/net.h: The conditional compilation for
-      '#if CONFIG_NFILE_DESCRIPTOR > 0' was wrong in both of these files.  It should
-      be '#if CONFIG_NFILE_DESCRIPTORS > 0'.  This causes a dup2() failure in THTTPD
-      and a failure to get a CGI page.  The consequence can be a very serious bug!
-    * configs/lpcxpresso-lpc1768/usbstorage, thttpd, and dhcpd: Add an USB storage,
-      THTTPD web server, and DHCP server configurations for the NXP LPCXpresso board.
-    * drivers/lcd/ug-9664hswag01.c and ssd1305.h: Add support for Univision UG-9664HSWAG01
-      OLED with Solomon Systech SD1305 LCD controller.
-    * configs/lpcxpresso-lpc1668/nx: Add a NX graphics configuration for the LPCXPRESO
-      board.
-    * graphics/nxglib/nxglib_nonintersecting.c: Fix some single bit errors in
-      calculation of non-intersecting regions.  This was causing an anomaly
-      in examples/nx in column 0.
-    * drivers/mtd/rammtd.c: Added a RAM based MTD driver.  This RAM driver simulates
-      FLASH and is useful for testing purposes.
-    * arch/arm/src/arm/up_head.S: Fix backward conditional compilation.  This cause
-      the configs/mx1ads configuration to fail to build but does not appear to affect
-      any other ARM9 build.
-    * fs/nxffs: Adding a tiny, wear-leveling FLASH file system for NuttX.  This
-      file system is intended to be small and will have some limitations.  The
-      implementation is incomplete on initial checkin.
-    * apps/examples/nxffs and configs/sim/nxffs:  Add a test a a configuration that
-      will be used to verify NXFFS.
-    * fs/fat/fs_fat32.c and fs_fat32util.c: Incorpated two bugs with fixed provided
-      by Sheref Younan.  Thanks!
-    * fs/nxffs: After a couple of weeks of testing and bug fixes, NXFSS appears

-    * tools/mkdep.sh: Should not report an error if there are no files on the command
-      line.  This happens normally in certain configurations.
-    * drivers/usbhost: Sheref Younan reported an error in the error handling when
-      connection to a USB device fails.  In certain fail cases, the logic would try
-      to free the device class instance twice, the first was okay, but the second
-      caused a crash.
-    * graphics/nxbe/nxbe_colormap.c: Fix error noted by Bassem Fahmy.  The function
-      nxbe_colormap was change to nxbe_configure... apparently "search-and-replace"
-      error. This error was not noticed before because most NX platforms do not use
-      colormapping.
-    * arch/rgmp and configs/rgmp.  Add 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.
-    * lib/stdio/lib_fclose.c: Must flush all buffered data when the file is closed.
-      Instead, it was discarding the buffered data.
-    * lib/stdio: All output stream logic was modified to support CONFIG_STDIO_LINEBUFFER.
-      If standard C buffered I/O is enabled (CONFIG_STDIO_BUFFER_SIZE > 0), then this
-      option may be added to force automatic, line-oriented flushing the output buffer
-      for putc(), fputc(), putchar(), puts(), fputs(), printf(), fprintf(), and vfprintf().
-      When a newline is encountered in the output string, the output buffer will be
-      flushed.  This (slightly) increases the NuttX footprint but supports the kind of
-      behavior that people expect for printf.

+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.
