+NuttX-7.14 Release Notes
+------------------------
+
+The 114th release of NuttX, Version 7.14, was made on January 28, 2016,
+and is available for download from the Bitbucket.org website.  Note
+that release consists of two tarballs:  nuttx-7.14.tar.gz and
+apps-7.14.tar.gz.  These are available from:
+
+    https://bitbucket.org/patacongo/nuttx/downloads
+    https://bitbucket.org/nuttx/apps/downloads
+
+Both may be needed (see the top-level nuttx/README.txt file for build
+information).
+
+Additional new features and extended functionality:
+
+    * Core OS:
+
+      - modules:  Add support for kernel modules:  insmod, rmmod, support
+        functions.  procfs support for user lsmod functioniality.
+      - SIGEV_THREAD:  Add support for the SIGEV_THREAD notification method
+        in struct sigevent.  This initial implementation will only work in
+        the FLAT build since it utilizes the work queue for signal
+        callbacks.  See the top-level TODO file for additional details.
+      - 64-Bit Timer:  If the 64-bit timer is selected, then use it whenever
+        clock_systimer() is called rather then chopping the 64-bit timer
+        down to 32-bits.  Add a new type, systime_t to represent the 32- or
+        64-bit system timer. This eliminates clock_systimer32() and
+        clock_systime64(); there is now only clock_systimer().
+
+    * Common Device Drivers:
+
+      - Telnet Driver: Move the Telnet driver from apps/ to
+        nuttx/drivers/net.  It is a driver a belongs in the OS.   Now works
+        like the loop device:  A new interface called telnet_initialize()
+        registers a telnet session "factory" device at /dev/telnet.  Via
+        ioctl, the factory device can create instances of the telnet
+        character devices at /dev/telnetN to support Telnet sessions.
+      - PCA9635PW:  Add a driver for the PCA9635PW I2C LED driver IC which
+        can be used to control the intensity of up to 16 LEDs.  From
+        Alexander Entinger.
+      - MCP9844: Driver for the MCP9844 I2C digital temperature sensor with
+        a selectable resolution.  From Alexander Entinger.
+      - PN532: Add driver for the NXP PN532 NFC-chip.  From Janne Rosberg
+        and others at Offcode Ltd.
+      - LSM9DS1:  Add driver for the STMicro LSM9DS1 chip. The LSM9DS1 is a
+        system-in-package featuring a 3D digital linear acceleration sensor,
+        a 3D digital angular rate sensor, and a 3D digital magnetic sensor.
+        From Paul Alexander Patience.
+      - CAN Interface:  Add more extensive error reporting capaibility to
+        the CAN interface definitions.  From Frank Benkert.
+      - SPI Interface:  Add an optional hwfeatures() method to the SPI
+        interface.
+
+    * Simulation Platform:
+
+      - NSH configuration uses the custom start up scriptwith a read-only
+        passwd file.  Includes hooks for an MOTD message.
+
+    * ARMv7-R
+
+      - ARMv7-R:  Add basic architecture support for the ARMv7-R processor
+        family.
+
+    * Atmel AVR:
+
+      - Atmega2560:  Add support for the Atmega2560.  From Dimitry Kloper.
+      - debug.h: Add an AVR-specific header file used when the AVR MEMX
+        pointer is used.  From Dimitri Kloper.
+
+    * Atmel AVR Boards:
+
+      - Arduino-Mega2560: Add support for the Arduino-Mega2560.  From
+        Dimitry Koper.
+
+    * Atmel SAMV7 Drivers:
+
+      - Port the TRNG driver from the SAMA5D3/4 to the SAMV7.
+      - Port the WDT driver from the SAMA5D3/4 to the SAMV7.
+      - Add an RSWDT driver.
+
+    * Atmel SAMV7 Boards:
+
+      - SAMV71-XULT:  Add configuration for testing OS modules.
+
+    * Freescale Kinetis:
+
+      - MK60N512VLL100: Add support for the MK60N512VLL100 Kinetis part.
+        From Andrew Webster.
+
+    * Freescale Kinetis Boards:
+
+      - ENET:  Numerous updates to the Kinetis ENET driver. That driver is
+        now functional. From Andrew Webster.
+
+    * NXP LPC43xx Boards:
+
+      - WaveShare LPC4337-WS:  Support for the WaveShare LPC4337-WS board.
+        From Lok Tep.
+
+    * STMicro STM32 Drivers:
+
+      - Timer Capture:  Add timer input capture driver.  From Pierre-Noel
+        Bouteville.
+
+    * STMicro STM32 Boards:
+
+      - Olimex STM32 H407:  Added a port to the Olimex STM32 H407 board.
+        This board features the STMicro STM32F407ZGT6 (144 pins).
+        Contributed by Neil Hancock.
+
+    * TI TMS550 Boards:
+
+      - TI LaunchXL-TMS57004:  Add basic board support for TI LaunchXL-
+        TMS57004.  Still a work in progress.
+
+    * C Library/Header Files:
+
+      - sys/time.h: Add timeradd(), timersub(), timerclear(), timerisset(),
+        and timercmp() as macros. These are non-POSIX interfaces, but
+        included in most BSD deriviatives, including Linux.  From Manuel St??.
+      - AVR support: Introduce support for Atmel toolchain in-flash strings.
+        Atmel toolchain AVR compiler provides a transparent in-flash object
+        support using __flash and __memx symbols. The former indicates to
+        compiler that this is a flash-based object.  The later used with
+        pointer indicates that the referenced object may reside either in
+        flash or in RAM. The compiler automatically makes 32-bit pointer
+        with flag indicating whether referenced object is in flash or RAM
+        and generates code to access either in run-time. Thus, any function 
+        hat accepts __memx object can transparently work with RAM and flash
+        objects.
+        For platforms with a Harvard architecture and a very small RAM like
+        AVR this allows to move all constant strings used in trace messages
+        to flash in the instruction address space, releasing resources for
+        other things. This change introduces IOBJ and IPTR type qualifiers.
+        The 'I' indicates that the object may lie in instruction space on a
+        Harvard architecture machine. For platforms that do not have __flash
+        and __memx or similar symbols IOBJ and IPTR are empty, making the
+        types equivalent to, for example, 'const char' and 'const char*'.
+        For Atmel compiler these will become 'const __flash char' and
+        'const __memx char*'.  All printf() functions and syslog() functions
+        are changed so that the qualifier is used with the format parameter.
+        From Dimitry Kloper.
+      - debug.h:  Add configuration to support an architecture-specific
+        debug.h header file. From Dimitri Kloper.
+      - netdb:  Add support for the use of a DNS resolver file like
+        /etc/resolv.conf.
+      - TEA:  Add an implementation of the Tiny Encryption Algorithm.
+      - math32.h:  Add some utilities to support 64-bit arithmetic
+        operations for platforms that do not support long long types.
+
+    * Tools:
+
+      - tools/cnvwindeps.c:  Add a tool that will convert paths in
+        dependencies generated by a Windows compiler so that they can be
+        used with the Cygwin make.
+      - tools/mkwindeps.sh: A script that coordinates use of cnvwindeps.exe.
+        Dependencies now work on the Cygwin platform when using a Windows 
+        ative toolchain.
+
+    * Applications: NSH
+
+      - Module Commands:  Add module commands: insmod, rmmod, and lsmod.
+      - Time Command:  Add a 'time' command that may be used to time the
+        execution of other commands.
+      - Password Commands:  Add useradd, userdel, and passwd commands.
+      - MOTD:  Now supports a Message of the Day (MOTD) that will be
+        presented after the NSH greeting.
+      - Session Logins:  All sessions may be protected with logins using the
+        encrypted password in /etc/passwd.
+      - Extended Logins.  Added optional platform-specific function to
+        perform password verification and optional delay after each failed
+        login attempt.
+
+    * Applications: apps/fsutils:
+
+      - apps/fsutils/passwd: Utility library for accessing a password file
+        like /etc/passwd.
+
+    * Applications: apps/netutils:
+
+      - apps/netutils/telnetd:  Now creates Telnet sessions by opening a new
+        factory device at /dev/telnet and then using ioctl calls to create
+        the session character drivers at /dev/telnetN.
+      - apps/netutils/netlib:  Add netlib_get_dripv4addr() and
+        netlib_get_ipv4netmask().  From Pelle Windestam.
+
+    * Applications: apps/examples:
+
+      - apps/examples/module:  Add a test harness for verifying NuttX kernel
+        modules.
+      - apps/examples/pca9635:  Add a simple test of PCA9635PW PWM LED driver.
+        From Alan Carvalho de Assis.
+      - apps/examples/ostest:  Add a test of POSIX timers using SIGEV_THREAD.
+
+Bugfixes.  Only the most critical bugfixes are listed here (see the
+ChangeLog for the complete list of bugfixes and for additional, more
+detailed bugfix information):
+
+    * Core OS:
+
+      - pthreads: CRITICAL BUGFIX: Logic was wiping out the indication that
+        of the type of a pthread.  Hence, it could be confused as a task.
+      - waitpid:  CRITICAL BUGFIX.  Add a reference count to prevent waitpid
+        from using stale memory released by the waited-for task group.
+      - clock_systimespec():  Fix an error in a time conversion.
+
+    * File System/Block Drivers:
+
+      - poll(): Fix handling of sem_tickwait() return value sem_tickwait()
+        does not return an -1+errno, it returns a negated errno value.
+        Noted by Freddie Chopin.
+
+    * Common Drivers:
+
+      - TUN Driver:  Fix a compile time error in the TUN driver.  From
+        Vladimir Komendantskiy.
+      - USB Host HID Parser:  Wrong size used in memcpy().  From Hang Xu.
+      - PCA9555: Fixed a bug in the function pca9555_setbit which occurs if
+        someone tries to set one of the pins 8-15. The problem is that
+        after the check if the pin is greater than 7 the variable addr is
+        incremented and used in the Call I2C_WRITEREAD. But later in the
+        call to the I2C_WRITE buf[0] is used as address but this address is
+        not incremented as it should be. Note address does mean the address
+        to the register in the ioexpander and not the I2C address.  From
+        Stefan Kolb.
+
+    * Networking:
+
+      - TCP/IOB:  Numerous fixes, mostly relate to TCP and IOB buffering
+        and race conditions.  These were necessary for for the NuttX
+        networking later to be stable in some stress testing.  From Andrew
+        Webster.
+
+    * Atmel SAMV7 Drivers:
+
+      - USBHS Device: In USBHS device driver, fix check if zero length
+        packet is needed.
+
+    * STMicro STM32 Drivers:
+
+      - OTG FS Host:  Fix some backward arguments to stm32_putreg().  Note
+        by Hang Xu.
+
+    * Tools:
+
+      - tools/mkdeps.c:  Extended/fixed support for --winpath option.
+        Dependencies now work under Cygwin with a native Windows toolchain.
+
+    * Build System:
+
+      - apps/platform/Makefile:  Use a relative path to the board directory
+        link rather than the absolute path.  For Cygwin, the absolute would
+        would need converted with cygpath.  But just using the relative path
+        is a simpler solution.
