 </p>

+  The previous NuttX version was 6.33.
+  The NuttX minor version number is incremented on each release, but the major version number is incremented only when an incompatibility with previous versions is included in the release.

+  Only the newer configurations generated by the <i>kconfig-frontends</i> tools will generate

+NuttX-7.1
+---------
+
+The 101st release of NuttX, Version 7.1, was made on March 15, 2014,
+and is available for download from the SourceForge website.  Note
+that release consists of two tarballs:  nuttx-7.1.tar.gz and
+apps-7.1.tar.gz.  Both may be needed (see the top-level nuttx/README.txt
+file for build information).
+
+  The previous NuttX version was 6.33.  The NuttX minor version number is
+  incremented on each release, but the major version number is incremented
+  only when an incompatibility with previous versions is included in the
+  release.  In this case, the legacy, manual configuration is no longer
+  supported by the NuttX build system beginning with NuttX 7.1.  Only the
+  newer configurations generated by the kconfig-frontends tools will generate
+  viable NuttX configurations.
+
+  All board configurations in the NuttX source tree have been converted to
+  use the newer configuration, but if you have some older style configurations
+  for you board, you will need to convert those configurations to use the
+  kconfig-frontends tools before taking any new code from the repository. See
+  http://www.nuttx.org/doku.php?id=wiki:howtos:convertconfig for some
+  guidelines.
+
+Additional new features and extended functionality:
+
+    * Core OS:
+
+      - System time logic now includes logic to measure and calculate the
+        CPU load percentage (from David Alessio).  This CPU load logic
+        extended to keep counts on each thread.  The per-thread CPU is
+        now reported in the procfs under <pid>/loadavg  An asynchronous,
+        "external" clock may be used to drive the CPU load calculations
+        for more accurate measurements when needed.
+
+    * File Systems:
+
+      - As mentioned above, the per-thread CPU load information is now
+        reported in the procfs under <pid>/loadavg.
+      - Many file system interfaces have been extended to operate on the
+        top-level NuttX pseudo filestem.  These include rmdir, mkdir,
+        rename, and unlink.  This capability can be disabled with
+        CONFIG_DISABLE_PSEUDOFS_OPERATIONS in order to keep the footprint
+        small.
+
+    * Networking:
+
+      - Numerous updates and improvements to the CC3000 driver from David
+        Sidrane.
+
+    * Common Drivers:
+
+      - Defined a mouse interface that is very similar to a touchscreen
+        interface, but allows reporting of all mouse buttons.  Also, unlike
+        touchscreen drivers, mouse drivers need to report positional data
+        with no button is pressed so that the mouse position can drive a
+        cursor.
+      - Added support for a USB HID boot mouse device.  Cursor support is
+        not integrated and must be provided by the application based upon
+        the reported mouse data.
+      - Support added for the MIO283QT9A LCD from Toby Duckworth.
+
+    * Atmel SAMA4E:
+
+      - Added complete architecture support for the Atmel AT91 SAM4E
+        Cortex-M4F parts.
+
+    * Atmel SAM4E Board Support:
+
+      - Add board support for the SAM4E-EK board.
+
+    * Atmel SAM4E Drivers:
+
+      - Added logic to manage the Cortex-M Cache Control block.
+      - Developed and integrated an Ethernet MAC driver for the SAM4E.
+      - Backported the SAMA5 SPI driver to the SAM3/4 architecture.  The
+        SAMA5 version supports both multiple SPI peripherals as needed by the
+        SAM3A and SAM3X and also supports DMAC (but not PDC) needed by the
+        SAM4E.
+
+    * Atmel SAM D20:
+
+      - Added basic architecture support for the Atmel AT91 SAM D20
+        Cortex-M0+ parts.
+
+    * Atmel SAM D20 Board Support:
+
+      - Added basic support for SAM D2 Xplained Pro board.  Currently, the
+        NuttShell (NSH) works reliably over a serial port.  An SPI driver
+        has also been developed.  Work with the SAM D20 has been temporarily
+        stopped, however, in order to focus on the SAM4E-EK.
+
+    * TI Tiva TMC4C123G:
+
+      - Added architecture support for the TI Tiva TM4C123G parts.  This was
+        merged into the existing support for the LM3S and LM4F families. 
+        All directory, file, and function references changed from m to tiva.
+
+    * TI Tiva TMC4C123G Board Support:
+
+      - Added basic board support for the TM4C123G-Launchpad.  As of this
+        release the TM4C123G-Launchpad board support is untested and likely
+        incomplete.
+
+    * STMicro STM32 Boards:
+
+      - configs/mikroe-stm32f4/src/up_mio283qt9a.c: The Mikroe STM32F4 can
+        now support the newer MIO283QT9A LCD. From Toby Duckworth.
+      - Miscellaneous changes to better support FPU on STM32F429 Discovery
+        from David Alessio.
+
+    * NXP LPC2378 Drivers:
+
+      - Incorporated I2C and SPI drivers for the LPC23xx from Lizhuoyi.
+
+    * QEMU i486 Drivers:
+
+      - New QEMU keyboard and VGA drivers from Lizhuoyi.
+
+    * Documentation:
+
+      - Added a coding standards document.  See 
+        http://www.nuttx.org/doku.php?id=documentation:codingstandard
+
+    * Configuration/Build System:
+
+      - A configuration option, CONFIG_DEFAULT_SMALL, was added to select
+        default values for configuration variables based upon whether you
+        want a smaller footprint or more features.  This is not very useful
+        if you are modifying existing configurations because then the
+        default values do not apply.
+      - CONFIG_DEFAULT_SMALL has been defined on all tiny MCU configurations
+        so that they do not grow so rapidly when new, optional features are
+        added.
+      - The legacy, manual configuration is no longer supported by the
+        NuttX build system.  Only the newer configurations generated by
+        the kconfig-frontends tools will generate viable NuttX
+        configurations.  All board configurations in the NuttX source tree
+        have been converted to use the newer configuration, but if you have
+        some older style configurations for you board, you will need to
+        convert those configurations to use the kconfig-frontends tools. See
+        http://www.nuttx.org/doku.php?id=wiki:howtos:convertconfig for some
+        guidelines.
+
+    * Applications:
+
+      - NSH can now use an EMACS-like command line editor.  This CLE, is
+        really more like the traditional readline than is the default, tiny
+        the NuttX readline .
+      - The touscreen example can now be configured to work with either a
+        touchscreen or a mouse device.
+      - Several NSH commands can now be used to operate on objects in the
+        top-level pseudo-filesystem: rmdir, mkdir, mv, and rm.  This
+        capability can be disabled with CONFIG_DISABLE_PSEUDOFS_OPERATIONS
+        in order to keep the footprint small.
+      - If both the CPU load feature and the procfs features are enabled,
+        then the NSH 'ps' command will show the CPU load used by each
+        thread.
+
+Bugfixes (see the ChangeLog for details).  Some of these are very important:
+
+    * Core OS:
+
+      - task_terminate()  always returned an error because the return value
+        was not being set correctly (from Gosha).
+      - nanosleep()  Fix a missing call to re-enable interrupts (from Jason
+        Jiang).
+
+    * File Systems:
+
+      - Fixed an error in the FAT logic that can cause file corruption.  The
+        error conditions are rare and only seen with very large files (from
+        Andrew Tridgell).  This replaces a previous, partial fix for the same
+        problem.
+      - Fixed memory leaks in the NXFFS open() and stat() implementations
+        (from Lzyy).
+      - The interfaces include opendir(), readdir(), et al, were modified so
+        that errors will not be reported if you attempt to list a empty
+        pseudo-directory.
+
+    * Networking:
+
+      - Fix one place where the connection reference count was not being
+        decremented in the socket close() logic.  This is really a cosmetic
+        change BUT when CONFIG_DEBUG_NET is enable, it will cause assertions.
+      - Backed out a small part of the NuttX 6.33 write buffering changed. 
+        David G says that this causes problems in connecting to a server.
+      - In DHCPD, there was a place where the logic called should not call
+        ntohl() inappropriately; the address was already in the correct
+        order.  How could DHCPD have worked with this bug?
+
+    * TI Tiva/Stellaris Drivers:
+
+      - Fixed cut'n'paste error that prevented UARTS2-7 from being used with
+        the LM4F120 Launchpad.
+      - Fixed several errors there were unmasked with UARTs > UART2 are
+        enabled (grom Gosha).
+
+    * Allwinner A10 Drivers:
+
+      - Fixed cut'n'paste error that prevented UARTS2-7 from being used with
+        the pcDuino.
+
+    * NXP LPC17xx Drivers:
+
+      - Fix an compilation error that crept into the LPC17xx USB host driver.
+
+    * STMicro STM32 Drivers:
+
+      - Fix cloned typo in the serial driver:  FLOWCONTROL vs FLOWCONROL.
+      - Disable SPI before changing DPI CR1 register (from David Sidrane).
+      - stm32 TIM: Set the timer CCMR when selecting timer channel.  From
+        David Sidrane.
+      - Fix typo in a Makefile: stm32_pwm.c not stm32_psm.c.  Noted by Max
+        Kriegleder.
+
+    * Library:
+
+      - More sscanf()  bug fixes from David Sidrane.
+
+    * Header files:
+
+      - cstdbool:  Ignore _Bool8 if CONFIG_C99_BOOL8=y
+
+    * Configuration/Build System:
+
+      - Several changes to restore the broken native Windows build 
+
+    * NuttShell (NSH):
+
+      - Use strncpy vs strcpy in the Telnet console logic to avoid
+        overruning the username and password buffers (from Bertold Van den
+        Bergh).
+      - Add a newline after printing the file in the 'cat' command.  This
+        prevents the NSH prompt from be in the same line as the final line
+        of the file in the case where there is no newline at the end of the
+        file.
