+NuttX-7.13 Release Notes
+------------------------
+
+The 113th release of NuttX, Version 7.13, was made on December 5, 2015,
+and is available for download from the Bitbucket.org website.  Note
+that release consists of two tarballs:  nuttx-7.13.tar.gz and
+apps-7.13.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:
+
+      - External RTC:  Added OS support for external RTC chips.
+      - boardctl():  Add a command to the boardctl() interface to obtain a
+        board unique ID.
+
+    * File Systems:
+
+      - TMPFS:  Add support for a new TMPFS, RAM file system.  The TMPFS
+        file system does not require any significant amount of memory
+        itself.  It will grow dynamically as files are added and shrink back
+        when files are deleted.  A very low overhead way to retain temporary
+        files.
+      - VFS:  The VFS was extended to support standard file operations on
+        block drivers (open, close, read, write, etc.).  The open() interface
+        accomplishes this by creating a temporary characer driver to mediate
+        the character oriented accesses to tje block driver.
+      - HOSTFS:  Added a HOSTFS file system for use with the simulator.  The
+        HOSTFS file system mounts in the simulated Nuttx context by provides
+        proxied access to the file system on the host PC.  This is useful for
+        providing file system content and nonvolatile storage of files in the
+        simulation environment.  From Ken Pettit.
+      - MTD/PROCFS:  Add an interface to un-register an MTD procfs entry.
+        From Ken Pettit.
+      - filemtd:  A new MTD conversion layer that will convert a regular file
+        (or driver file) to an MTD device.  This is useful for testing on the
+        simulation using the HOSTFS.  From Ken Pettit.
+      - PROCFS:  Extended to include networking entries in the procfs. Device
+        status, device statistics, and network statistics are now available
+        from the PROCFS.
+      - PROCFS:  The PROCFS file system can now be configured so that it
+        supports runtime registration of PROCFS entries with
+        CONFIG_FS_PROCFS_REGISTER=y.
+
+    * Graphics/Graphic Drivers:
+
+      - ST7565 Driver:  Extend to include support for the ERC12864-3. From
+        Pierre-noel Bouteville.
+
+    * Common Device Drivers:
+
+      - User buttons: Added a character driver to support application access
+        to board buttons.  Supports notification of button activity via
+        signals.
+      - User LEDs:  Added a character driver to support application access
+        to on-board LEDs.
+      - Zero Cross: Added a Zero Cross device driver support.  From Alan
+        Carvalho de Assis.
+      - MAX6675:  Added support to Thermocouple-to-Digital converter MAX6675.
+        From Alan Carvalho de Assis.
+      - BCH:  Block-to-character (BCH) driver should forward ioctl() calls
+        to the contained block driver.
+      - S25FL1xx:  Added a S25FL1xx QuadSPI FLASH driver.
+      - On-Chip FLASH: Added an upper half MTD device that can use the
+        interfaces defined in included/nuttx/progmem.h to provide a
+        standard MTD driver.
+      - Serial: Implemented high level DMA infrastructure for serial
+        devices.  From Max Neklyudov.
+      - AT24XX:  Add support for multiple AT24xx EEPROM parts, each with
+        unique I2C addresses, but otherwise identical.
+      - External RTC:  Added drivers for external I2C RTC chips: DS3102,
+        DS1307, DS3231, DS3232, and NXP PCF85263.
+      - W25: Added support for byte write mode to the W25 FLASH driver. From
+        Ken Pettit.
+      - dev/loop:  Added a loop character device.  losetup() and loteardown()
+        should not be called directory from applications. Rather, these
+        functions are now available as IOCTL commands to the loop driver.
+      - dev/smart:  Added support for a /dev/smart loop device. From Ken
+        Pettit.
+
+    * Networking:
+
+      - Driver Statistics: Most network drivers do not support statistics.
+        Those that do only supported them when DEBUG is enabled.  Each
+        driver collected an architecture specific set of statistics and
+        there was no common mechanism to view those statistics.  Thus,
+        the driver feature was mostly useless.  This release standardizes
+        the driver statistics and puts the definition in the common network
+        device structure defined in netdev.h where they can be accessed by
+        network applications.  All Ethernet drivers that collect statistics
+        have been adapted to use these common statistics.
+
+    * Simulation Platform:
+
+      - W25 FLASH:  Added support for W25 FLASH simulation. From Ken Pettit.
+      - HOSTFS: Added support for the HOSTFS file system (see "File Systems",
+        above).
+
+    * Atmel SAMV7:
+
+      - SAME70:  Added support for the SAME70 family of chips.
+      - Tickless: SAMV7 now supports the tickless mode of operation.
+
+    * Atmel SAMV7 Drivers:
+
+      - MPU:  Added MPU and protected build support.
+      - QSPI:  Added a QuadSPI FLASH driver.  This driver operates in the
+        memory-mapped, Serial Memory Mode (SMM).
+      - FLASH:  Added support to write on-chip FLASH.
+      - Timer/Counter:  TC driver ported to SAMV7 from the SAMA5.  Free-running
+        and one-short timer logic also ported.
+      - PCK: Brought programmable clock (PCK) logic from SAMA5 into SAMV7.
+      - Timer/Counter:  Support PCK6 as an optional source for the timer/
+        counter clock.
+
+    * Atmel SAMV7 Boards:
+
+      - SAME70-Xplained:  Add NSH and networking configurations for the
+        SAME70 Xplained board.  Includes verified support for serial console,
+        LEDs, buttons, SDRAM, HSMCI SD card, and networking.
+      - SAMV7-XULT and SAME70-Xplained: If Tickless mode is selected then
+        enable PCK6 as a timer/counter clock source
+
+    * STMicro STM32:
+
+      - CCM PROCFS: Is no longer a part of the 'base' procfs entries and can
+        now only be supported via run time registration with
+        CONFIG_FS_PROCFS_REGISTER=y.
+
+    * STMicro STM32 Drivers:
+
+      - Timers:  Add a compatible lower-half timer driver for use with the
+        common timer upper-half driver.  From Wail Khemir.
+
+    * STMicro STM32 Boards:
+
+      - STM32F4-Discovery: Add low level support for the Zero Cross driver
+        for the STM32F4-Discovery.  From Alan Carvalho de Assis.
+      - STM32F4-Discovery: Add board config to support for the MAX6675. From
+        Alan Carvalho de Assis.
+
+    * C Library/Header Files:
+
+      - bsearch():  Added the bsearch() function from NetBSD.
+      - freopen():  Added support for freopen().
+      - strftime():  Added day-of-week support (when avaialable).
+
+    * Tools:
+
+      - nxstyle: Add crappy style checking tool nxstyle.c.  See thee tools/
+        README file for more info.
+
+    * Applications: NSH
+
+      - mksmartfs command: Add configuration option to supported multiple
+        rootdirectories. From Ken Pettit.
+      - Add support for 'basename' and 'dirname' commands.
+      - set command:  Like bash, NSH set command now strips off any leading
+        or trailing whitespace.
+      - mount command: The mount commands now accepts mount options
+        (currently needed only for the hostfs file system).  From Ken
+        Pettit.
+      - losetup command:  NSH no longer calls losetup() and loteardown
+        directly. Now it opens /dev/loop and accomplishes these things
+        using ioctl() calls.
+      - ifconfig command:  If CONFIG_NETDEV_STATISTICS=y, then print the
+        network driver statistics in the ifconfig.
+      - ifconfig, ifup, and ifdown:  These commands now uses /proc/net/<dev>
+        to view network device configuration and status and /proc/net/stat
+        to show network statistics.  A consequence of this is that you
+        cannot view this network information if the procfs is not enabled
+        and mounted at /proc.
+      - losmart command:  Added a new NSH losmart command.  losmart setups
+        up a loop device for the smart MTD driver similar to losetup but
+        with different syntax.  From Ken Pettit.
+      - ps command:  The 'ps' command now uses /proc/<pid>/ to obtain task
+        status information.  A consequence of this is that you cannot use
+        the 'ps' command if the procfs is not enabled and mounted at /proc.
+ 
+    * Applications: apps/system:
+
+      - apps/system/hexed:  Port the hexed command line hexadeciamal editor
+         to Nuttx.  See http://apps.venomdev.net/hexed/.
+
+    * Applications: apps/fsutils:
+
+      - apps/fsutils/smartfs: Move into apps/fsutils from kernel, now uses
+        only open and ioctl.  From Ken Pettit.
+
+    * Applications: apps/examples:
+
+      - apps/examples/fstest:  Add a generic file system test.  This is
+        essentially the same as examples/smart, but has all of the SmartFS
+        specific logic ripped out.  This was created for testing the new
+        TMPFS.
+      - apps/examples/zerocross: Add a Zero Cross application example. From
+        Alan Carvalho de Assis.
+      - apps/examples/media:  Add a simple test for access of media via a
+        block driver or MTD driver.
+
+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:
+
+      - Fixed an error in clock_timespec_subtract().  Found by Lok.
+      - pthreads: CRITICAL BUGFIX: Logic was wiping out the indication that
+        of the type of a pthread.  Hence, it could be confused as a task.
+        Found because this was causing a crash when /proc/nnn/cmdline was
+        printed.
+
+    * File System/Block Drivers:
+
+      - SMART MTD: Fix some Smart wear-leveling bugs.  Fixed SmartFS wear
+        level error that occurs when the logical sector size is too small to
+        save all wear level status bytes in a single sector.  Logical
+        sectors 1 and 2 were simply not being allocated and then the
+        read_sector and write_sector routines were failing.  From Ken
+        Pettit.
+
+    * Graphics/Graphic Drivers:
+
+      - ILI9432:  Fixed errors in orientation. Portrait, RPortrait, and 
+        Landscript should work correly now.  They were displayed mirrored.
+        From  Marco Krahl.
+
+    * Common Drivers:
+
+      - CAN:  Fix a problem in the CAN upper-half driver that occurs only
+        for CAN hardware that support a H/W FIFO of outgoing CAN messages.
+        In this case, there can be a hang condition if both the H/W and
+        S/W FIFOs are both full.  In that case, there may be no event to
+        awaken the upper half driver.  Add a new (conditional) CAN upper
+        half interface called can_txready() that can be used by the lower
+        half driver to avoid this hang condition.
+      - MS58xx:  Fix some issues with initialization and with CRC
+        calculation.  From Karim Keddam.
+      - W25: Fixed W25 FLASH driver page read/write logic. From Ken Pettit.
+
+    * Atmel SAMV7 Drivers:
+
+      - USART1 pin configuration: Reconfigure System I/O when using USART1.
+        From Frank Benkert.
+      - MCAN:  Added a call to can_txready() to the MCAN driver.
+
+    * STMicro STM32 Drivers:
+
+      - stm32 F4:  Fix some TIM12 pin mappings.  From Max Kriegleder.
+
+    * STMicro STM32 Boards:
+
+      - STM32F429i-Disco:  Calculated partition boundries based on page
+        block sizes but mtd_partition() is expecting calculations based on
+        erase block size. From Alan Carvalho de Assis.
+
+    * C Library/Header Files:
+
+      - sys/types.h: When building on a 64-bit machine, the size of size_t
+        should be 64-bits. In general, I believe that sizeof(size_t) should
+        be the same as sizeof(uinptr_t).  mmsize_t should always be 32-bits
+        in any event.  The last change to stddef has been backed out.  With
+        these changes, the simulator builds without errors or warnings an a
+        64-bit machine.
+
+    * Applications: apps/nshlib:
+
+      - The I/O buffer, g_iobuffer, should not be a global buffer.  That
+        will not work in an environment where there are multiple NSH
+        sessions.  The I/O buffer must, instead, be a part part of the
+        session-specific data defined in nsh_console.h.
