+NuttX-6.32
+----------
+
+The 100th release of NuttX, Version 6.33, was made on January 30, 2014,
+and is available for download from the SourceForge website.  Note
+that release consists of two tarballs:  nuttx-6.33.tar.gz and
+apps-6.33.tar.gz.  Both may be needed (see the top-level nuttx/README.txt
+file for build information).
+
+Additional new features and extended functionality:
+
+    * Core OS Interfaces
+
+      - nanosleep() added.  sleep() and usleep() are not longer core OS
+        interfaces.  These have been moved into the library and re-implemented
+        as simple wrappers around nanosleep().
+
+    * File Systems
+
+      - procfs restructure by Ken Pettit.  Added files for MTD status.
+      - procfs extended to show uptime and task group status.
+      - procfs now shows stack information.
+
+    * Networking
+
+      - Add support for the SO_LINGER socket option.  Extended from logic
+        provided by Jason Jiang.  Enabled with  CONFIG_NET_SOLINGER.
+      - TCP write buffering support added.  From Jason Jiang.
+      - Changes from Max Holtzberg to improve how network status is
+        reported.  New controls to manage carrier detect.
+
+    * Graphics
+
+      - Massive reshuffling of files with little or no logic changes.   This
+        reshuffling was necessary to build graphics applications with the
+        kernel builds where the graphics application lie in user space and
+        the core graphic server likes in kernel space.  Moved much logic out
+        of nuttx/graphics to a new user library, libnx.
+
+    * Cortex-A5/A8/A9
+
+      - Existing Cortex-A5 support updated to include Cortex-A8/9.
+      - Add the syscall.h header file needed for the Cortex-A architecture.
+      - Start-up logic now supports execution from FLASH with .data and
+        .bss in SDRAM.  This was not possible prior to this because .bss
+        and .data were initialized before SDRAM was configured.
+
+    * Allwinner A10:
+
+      - Basic support for the Allwinner (A10 Cortex-A8) is in place.
+
+    * Allwinner A10 boards
+
+      - Support for the pcDuino v1 board has been added.  This support
+        is not yet very mature and still lacks many drivers.  It is a
+        good starting point, however, if anyone wants to develop A10
+        support.
+
+    * Atmel SAMA5D3X
+
+      - Start-up logic now supports execution from FLASH with .data and
+        .bss in SDRAM.  This was not possible prior to this because .bss
+        and .data were initialized before SDRAM was configured.
+
+    * Atmel SAMA5D3X Boards
+
+      - Partial logic in place to support the OV2640 camera.  Still needs
+        quite a bit of additional logic to be useful.
+
+    * ARMv7-M
+
+      - Add support for high priority, nested interrupts. This change
+        effects not only core ARMv-7M logic, but all ARMv7-M MCU logic:
+        LM3S, LM4F,  LPC17xx, LPC43xx, SAM3, SAM4, and STM32. See
+        http://www.nuttx.org/doku.php?id=wiki:nxinternal:highperfints
+
+    * STMicro STM32
+
+      - Add clocking support for STM32F107 USB OTG FS (which does not yet
+        work)
+      - Single-wire UART support for the F1 series from Thomas Grubler.
+
+    * STMicro STM32 Boards
+
+      - The Viewtool board can now be configured to support either the
+        STM32F103VCT6 or the STM32F107VCT6.
+      - The Viewtool STM32F107VCT6 now supports networking with the
+        DP83848C module installed.
+      - Add support for Viewtool SSD1289-based LCD on the Viewtool
+        STM32F103VCT6 board (untested)
+      - Add support for the XPT2046 touchscreen controller on the Viewtool
+        LCD module connected to the Viewtool STM32F103 board.
+      - Added kernel mode build support for the STM3240G-EVAL board.  Added
+        a new kernel mode NxWM build configuration
+      - C++ static constructor logic from the nuttx/configs/stm3240g-eval/
+        directory to the apps/platform/stm3240g-eval/up_cxxinitialize.c
+        where is belongs so that it is available in user-space in the kernel
+        mode build.
+      - Add native Windows build support for the Olimex STM32 P107.  From
+        Max Holtzberg
+      - Support for the STM32VL-Discovery board. Contributed by Alan
+        Carvalho de Assis
+      - Added a configuration for testing simple configurations on the
+        PX4FMU v2.
+
+    * ZiLOG ZNEO Boards
+
+      - Add an NSH configuration for the Z16F2800100ZCOG ZNEO board.
+      - Added support for the Toyaga 16Z ZNEO board.  The 16Z board is
+        based on the ZiLOG ZNEOZ16F2811AL20EG part.  See
+        https://github.com/toyaga/16z for further information
+      - Developed a patch to work around a compiler error that is revealed
+        when building the NSH configuration.
+
+    * Architecture-Independent Drivers
+
+      - OV2640 Camera Driver.
+      - Support for the Sharp Memory LCD from Librae.
+
+    * Library
+
+      - Pattern matching logic extended to handle set of characters and
+        ranges of character values.  From Ken Pettit.
+      - sleep() and usleep() move library.  These are not longer core OS
+        interfaces; they are simple wrappers for the nanosleep().
+      - Add an implementation of gets_s().
+      - Extend fopen() to include support for C11 exclusive open ("x")
+        open mode.
+      - Add an implementation of stpcpy()
+      - strtol(), strtoll, strtoul(), strtoull(), and strtod() from
+        libc/string to libc/stdlib where they belong.
+
+    * Header Files
+
+      - Add rsize_t to include/sys/types.h
+      - Add the C11 thread.h header file
+
+    * Configuration/Build System
+
+      - Top level Makefile now supports qconfig and/or gconfig targets that
+        may be used for configuration.  These may be used if you build
+        kconfig-frontends with support for kconfig-qconf and/or
+        kconfig-gconf.
+      - Add CONFIG_DEBUG_NOOPT.  Now you can independently enable/disable
+        debug symbols and optimization
+      - File system related header files moved to include/nuttx/fs
+      - Video related header files moved to include/nuttx/video
+      - Changes for native Windows build: fix creation of a .version file
+        if one does not exist.  Make sure that the APPDIR environment
+        variable is set before configuring.  From Max Holtzberg.
+      - Board configuration sub-directory can now be specified.  The default
+        need not be used.  This is  only useful when CONFIG_ARCH_BOARD_CUSTOM
+        is selected and there is no meaningful default sub-directory.
+      - Many functions renamed to better conform with the naming standard:
+        up_buttoninit() renamed to board_button_initialize(), up_buttons()
+        renamed to board_buttons(), up_irqbutton() renamed to
+        board_button_irq(), up_ledinit() renamed to board_led_intialize(),
+        up_ledon() renamed to board_led_on(), and up_ledoff() renamed to
+        board_led_off(). All prototypes removed from board.h header files.
+        Now ONLY prototypes in include/nuttx/arch.h.
+
+    * Applications
+
+      - NSH: Refactor. Separate NSH command handling and command execution
+        from NSH line parsing.
+      - NSH: Will now support multiple commands on a command line, each
+        separated with a semi-colon.
+      - NSH: Add support of commands enclosed in back quotes as command
+        arguments.
+      - NSH: Can now handle arguments that are concatenations of constant
+        strings, command return data, application return data, and
+        environment variables.
+      - NSH: Add true and false commands.
+      - NSH: Add support for while-do-done and until-do-done loops.  These
+        only work when executing a script file because they depend on the
+        ability to seek in the file to implement the looping behaviors.
+        Can be conditionally compiled out to reduce footprint.
+      - NSH: Loosen up if-then-else-fi syntax to allow a command to be on
+        the same line as the then or else tokens like:
+        "if true; then echo true; else echo false; fi".  More like bash.
+      - NSH: Add a break command that can be executed with a loop to
+        terminate the loop immediately.
+
+      - system/inifile:  A simple .INI file parser.
+      - system/vi:  Add support for a tiny, VI work-alike editor.  This is
+        a minimal full screen editor that words with a terminal emulator
+        that using VT100 commands.
+
+Efforts In Progress.  The following are features that are partially
+implemented but present in this release.  They are not likely be be
+completed soon.
+
+    * kconfig-fronted Configuration:
+
+      - Conversion of old configurations to use the kconfig-frontends
+        tool is an ongoing effort that will continue for some time.
+        At this time, only 53% of the configurations have been converted
+        to use the kconfig-frontends tools.
+
+Bugfixes (see the ChangeLog for details).  Some of these are very important:
+
+    * Core OS
+
+      - Added missing sem_timedwait() system call.
+
+    * Networking
+
+      - Prevent tcp_connect callback from being double freed.  From Max
+        Holtzberg
+      - uiplib:  Support new definitions and state passing for network
+        device status. From Maz Holtzberg.
+
+    * File Systems
+
+      - FAT:  (1) A correction to FAT cluster allocation, and (2) Fix to some
+        root directory logic that was conditionally done only for FAT 32.
+        Apparently this needs to done for all FAT types.  Both from Andrew
+        "Tridge" Tridgell via Lorenz Meier.
+
+    * Binary Formats
+
+      - Fix a small memory leak when attempting to load a program from a file.
+
+    * Cortex-A8/9
+
+      - Fix some errors in the cache invalidation logic (only seem to matter
+        for Cortex-A8).
+      - Add more nop's after enabling the MMU.  The cortex-a8 seems to need
+        these
+
+    * Graphics
+
+      - Fix a typo that caused a compilation error when
+        CONFIG_NXCONSOLE_BPP < 8.  From Librae
+
+    * ARMv7-M
+
+      - Correct alignment of RAM vector table.
+      - Interrupt handling: Do not disable and enable the IRQ on each
+        entry, (2) this interferes with controlling the IRQ interrupt
+        setting from interrupt handlers, and (3) up_disable_irq() does
+        not work anyway so that this has never done anything.
+      - Fix all implementations of up_disable_irq() for all Cortex-M3 and
+        M4 architectures:  To enable an interrupt on the Cortex-M3/4 CPU,
+        you need to set a bit in the ISER register.  To disable the
+        interrupt, you need to set a bit in the ICER register.  Existing
+        logic was trying to disable interrupts by clearing the bit in the
+        ISER register.  That will not work; writing a '0' to the ISER
+        register has no effect.  That  means that up_disable_irq() was
+        doing nothing!  It turns out that that is not really important
+        because up_disable_irq() is not really used for that purpose.  But
+        some spurions STM32 ADC interrupts have been reported to me and this
+        turned out to be the cause in that case.  Thanks to Manuel Stühn for
+        the tip.
+
+    * STMicro STM32
+
+      - Fix configuration and pin definitions that would prevent building
+        USB for the connectivity and performance lines.
+      - STM32L15xx: Fix a typo in USB pin definitions
+      - Fix pin definition names for SPI2 MOSI and MISO. Noted by Brian Webb
+      - Various fixes for STM32F103ZE SPI3 pin mapping definitions.  From
+        Steve Redler IV
+
+    * STMicro STM32 Boards
+
+      - Olimex STM32-P107:  Failed to build if SPI3 for UEXT is not remapped.
+        From Max Holtzberg
+
+    * x86 Boards
+
+      - Add a configuration option to select the -m32 compiler option when
+        building for a 32-bit target on a native 64-bit compiler.  So far,
+        only used for the qemu/i486 configuration.
+      - Patch from Matt Campbell to fix 'Error: .size expression for idle_stack
+        does not evaluate to a constant".
+
+    * Library
+
+      - strftime(): Needs null termination on the generated string.  From
+        Max Holtzberg.
+      - Typo in ctype.h macro name: iscntrl(), not iscontrol().
+      - If there are no arguments (argc == 1), then getopt() will leave the
+        optind variable in an undefined state (2014-1-20).
+      - ARMv7-M memcpy(): Assembler changes with the gcc-47 distribution
+        from ARM mean that we need to be explicit about branch sizes; one
+        or more of the wide branch opcodes results in bad table branching.
+        From Mike Smith.
+
+    * Configuration/Build System
+
+      - Fixes for some tools/ for Windows build issues from Max Holtzberg.
+      - Config.mk: 'cypath' must be called if we are using a Windows native
+        toolchain with the Cygwin 'make' to convert paths to proper
+        Windows paths.  From Richard Cochran.
+      - ARM Makefile: Dependency directory list is now computed from the
+        VPATH.  From Richard Cochran.
+      - builtin/Makefile: Fixes for native Windows build from Max Holtzberg.
+      - Refactor some configuration dependencies:  NSH networking features
+        should depend on netutil selections; netutil selections, in turn,
+        should depend on networking selections.
+
+    * Applications
+
+      - NSH: Modified the df -h logic to eliminate truncating numbers in
+        conversion (like 7900 -> 7M).  From Ken Pettit.
