+NxWidgets-1.15
+==============
+
+The 16th release of the NxWidgets package was made on April 14, 2015.  This
+release depends on NuttX-7.9 or above and should not be used with older
+NuttX releases.

- This release is primarily a bugfix release for the NuttX-7.7 version that
-  was release just two weeks prior.  That release included substantial
-  modifications in the NuttX networking to accommodate support for IPv6.  This
-  release follows close behind NuttX-7.7 in order to correct some the problems
-  discovered in that networking code.  This release does, however, include a
-  small number of new features and bug fixes unrelated to NuttX networking.

+NuttX-7.9
+---------
+
+The 109th release of NuttX, Version 7.9, was made on April 14, 2015,
+and is available for download from the SourceForge website.  Note
+that release consists of two tarballs:  nuttx-7.9.tar.gz and
+apps-7.9.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:
+
+      - Assertions: Add support for dumping board-specific information on
+        assertions. From David Sidrane.
+      - boardctl(): :  Add a new non-standard OS interface called boardctl().
+        This is similar to a driver IOCTL call.  But this is an IOCTL call
+        directly on the board logic.  This function will eventually replace
+        all of the ad hoc OS interfaces that are current used to perform
+        application specific initialization and application driver test
+        configuration.  It essentially formalizes and institutionalizes
+        these rogue interface in to at least a single crazy call.
+
+    * Graphics:
+
+      - Line Joins:  Line drawing graphic functions now take an argument that
+        will draw a circular "cap" on the ends of lines to support cleaner
+        joining of lines segments..
+
+    * Common Drivers:
+
+      - SPI iInterface:  Add an SPIDEV_USER so that there can be board-
+        specific definitions of SPI devices.
+      - I2C Interface:  Add a user provided void * argument to the I2C
+        callback method for the I2C slave interface.  Suggested by Nate
+        Weibley.
+      - AT24 EEPROM Driver: Add support for (1) the byte-oriented read()
+        method, (2) devices that have extended memory regions, and (3)
+        devices that use 8-bit addressing.
+      - Freescale MPL115A barometer: Add driver for the Freescale MPL115A
+        barometer.  From Alan Carvalho de Assis.
+      - CS2100-CP: Add a driver for the CS2100-CP Fractional-N Multipler
+        chip.
+      - RTC IOCTls:  Added the definitions of a driver based RTC interfaces
+        and RTC upper half driver.
+
+    * File Systems/Block Drivers/MTD:
+
+      - umount2():  Added to support un-mount flags. umount() is now a macro
+        that just calls umount2() with flags = 0.
+      - File system interface: Pass the umount2() flags to every unbind()
+        implementation.  That is where the decision to umount or not and how
+        to umount will be made.
+      - FAT unbind: Add support for umount2(target, MNT_FORCE) in the FAT
+        file system.
+
+    * Networking:
+
+      - netdev_register(): Improve the network device registration logic.
+        When multiple link types are used, modify how each interface number
+        is assigned to the device name by incrementing the device number
+        individually for each interface link type.  From Max Neklyudov.
+      - Add TUN network device.  Used to support the Netutils PPPD
+        implementation. From Max Neklyudov.
+
+    * ARMv7-M
+
+      - ARM Cortex-M7:  Add basic support for the Cortex-My architecture.
+      - ARMv7 Common Lazy Exception handling. Add common support for lazy
+        FPU state saving.  MCU-specific lazy FPU saving was already in place.
+        This change just makes the code share-able.
+
+    * Atmel SAMA5D3/4 Drivers:
+
+      - SAMA5 Serial:  Backport support for flowcontrol and termios from
+        SAM3/4.
+
+    * Atmel SAMV7:
+
+      - Atmel SAMV7:  Add architecture support for the Atmeal SAMV7 family
+        (Cortex-M7)
+
+    * Atmel SAMV7 Boards:
+
+      - Atmel SAMV71 Xplained Ultra:  Add board support for this SAMV7 board.
+        This initialize release includes support for: SDRAM, TWI/I2C, SPI,
+        Ethernet, HSMCI, DMA, GPIOs, UARTs, AT24 EEPROM and the maXTouch
+        Xplained Pro LCD.  Drivers are available for SSC/I2C, the WM8904,
+        the maXTouch trouchscreen, and USB device but have not yet been
+        fully integrated in this release.
+
+    * SiLabs EFM32 Drivers:
+
+      - EFM32 USB Device is now functional with the efforts of From Pierre-
+        noel Bouteville.
+      - EFM32 I2C:  Add I2C driver.  From Pierre-noel Bouteville.
+
+    * STMicro STM32:
+
+      - STM32F372/F373: Adds architecture support for this STM32 parts.
+        Tested on STM32F373CC.  Contributed by  Marten Svanfeldt.
+
+    * STMicro STM32 Drivers:
+
+      - STM32 RTCC: Break out a new internal interface, stm32_rtc_setdatetime().
+        This eliminates some un-necessary time conversions.  From Freddie Chopin.
+      - STM32 RTCC: Add an implementation of the RTC lower half interface
+        for the STM32.
+      - STM32 RTCC: Extend the RTC interface to support reading subseconds.
+        From Jussi Kivilinna.
+      - STM32 BBSRAM: Adds the ability to use the STM32F2 and STM32F4 Battery
+        Backed SRAM in the file system. With an option to Save Panic context
+        to one of the files. From David Sidrane.
+
+    * STMicro STM32 Boards:
+
+      - Olimexino-STM32: Board support for the Olimexino STM32 board from David
+        Sidrane.
+      - Viewtool-STM32F107:  Add support for an optional, add-on Freescale
+        MPL115A baramoter.  From Alan Carvalho de Assis.
+
+    * TI Tiva:
+
+      - TM4C1294:  Add support for the TM4C1294.  Contributed by Frank Sautter.
+
+    * TI Tiva Drivers:
+
+      - Tiva ADC:  Updated files to allow for ADC and PWM triggering by a
+        timer.  Refactoring of ADC implementation.  From Calvin Maguranis.
+      - Tiva Timer: Refactoring by Calvin Maguranis
+
+    * TI Tiva Boards:
+
+      - TM4C123G-launchpad: Add ADC support.  From Calvin Maguranis.
+      - TM4C123G-launchpad: Add board button interrupt support.  From Calvin
+        Maguranis.
+      - TM4C1294 Launchpad:  Add support for the TM4C1294 Launchpad.
+        Contributed by Frank Sautter.
+
+    * Microchip PIC32
+
+      - PIC32MZ:  Add architectural support for the PIC32MZ (MIPS32 M14k).
+        Includes contributions from Kristopher Tate.
+
+    * Microchip PIC32MZ Boards
+
+      - PIC32MZ Starter Kit: Add basic board support for the PIC32MZ.
+        Includes contributions from David Sidrane.
+
+    * C Library/Header Files:
+
+      - gettimeofday():  This function is no longer a core OS interface.  It
+        is only a wrapper around clock_settime().
+      - settimeofday(): Added. gettimeofday has been decrecated in POSIX
+        2008. settimeofday() was never part of POSIX, but I decided to add
+        it to libc as well just for symmetry.
+      - Day-of-Week: Add CONFIG_TIME_EXTENDED to support the last 3 members
+        of the tm struct and support for filling them in with the day of the
+        week. From David Sidrane.
+      - sighold(), sigrelse(), sigignore(), sigset() and sigpause():  New
+        signal handling functions.
+      - sys/select.h: Extend the fd_set type definition so that it can
+        handle more than 32 descriptors (if so configured).  From Max
+        Neklyudov.
+      - netdb.h:  Add a mostly-commented-out version of the standard netdb.h
+        header file.
+      - include/nuttx/board.h:  Remove common board function prototypes from
+        other files and consolidate them in this new header file.
+
+    * Applications:
+
+      - OS test: Improved error checking for sem_timedwait() from Juha
+        Niskanen.
+      - OS test: Add a simple test of sigprocmask, sighold, and sigrelse.
+      - PPPD test:  Add PPPD test case.  Split out from the PPPD daemon by
+        Brennan Ashton.
+      - Netutils: Add a PPP daemon.  From Max Neklyudov.
+      - NSH:  NSH initialization now calls boardctl(BOARDIOC_INIT) instead
+        of nsh_archinitialize().   Remove support for CONFIG_NSH_ARCHMAC.
+        It is not used and there are better ways to do that operation.
+      - NSH:  Allow NSH 'date' command with no hardware RTC.  This command
+        is useful without an RTC too.  Also, this permits testing on the
+        simulator which never has an RTC.
+      - apps/examples/:  Serveral tess changed (touchscreen adc, pwm,
+        graphics).  No longer call directly into the OS, but rather
+        indirectly via boardctl().
+      - Modbus: Includes extensions to support RTU master mode by
+        Armink(383016632@qq.com): https://github.com/armink/FreeModbus_Slave-Master-RTT-STM32.
+        Ported to NuttX by Darcy Gong.
+      - TZ database:  All logic to build timezone database needed for
+        localtime() support.  Does not do much else yet.
+
+Efforts In Progress.  The following are features that are partially
+implemented but present in this release.  They are not likely to be
+completed soon.
+
+    * Processes.  Much of the work in this release is focused on the
+      realization of Unix-style user processes in NuttX.  There is more to
+      be done, however.  The full roadmap and status is available at:
+      http://www.nuttx.org/doku.php?id=wiki:nxinternal:memconfigs#the_roadmap_toward_processes
+
+    * XMega:  There are some fragments in place for an XMega port.  That
+      port has not really started, however.
+
+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:
+
+      - atexit(): Fix compile failure due to reference to undefined variable
+        in certain configurations.  From Juha Niskanen.
+      - syscalls: Last changes to message queue prototypes did not make it
+        into call gate logic.  Some additional errors had crept as well since
+        the system calls are seldom used.
+      - waitpid(): Do not use uninitialized boolean in waitpid().  From Juha
+        Niskanen.
+      - Timing functions:  Fix some nanosecond comparisons.  Comparisons should
+        be greater than OR EQUAL TO 1000000000 for maximum value of nanoseconds
+        in struct tm.  From Juha Niskanen.
+      - Time initialization: Fix an error in time initialization when there
+        is not RTC and the time is initialized from a fixed configured value.
+        The call to clock_calendar2utc() was returning the time in units of
+        seconds.  The initialization logic, however, was expecting to get
+        time in units of days.  This problem has been there forever but
+        obviously has not significant impact to behavior in systems where
+        time is not visible.
+      - mq_timedsend():  Should not check for valid time if there is space
+        in the message queue.  Noted by Freddie Chopin.
+      - select() and sem_timedwait(): Fix places where the errno value was
+        being overwritten by subsequent actions so that the returned errno
+        value was incorrect.  From Max Neklyudov.
+      - clock_systimer64(): Fix a problem in clock_systimer64 that occurs
+        when (1) the 64-bit system time is enabled, and (2) the value of
+        CONFIG_USEC_PER_TICK is less than 1 milliseconds (such as when using
+        the tickless mode of operation).  In that case, the conversion of
+        time to 64-bit millisecond value in clock_systmer64() causes some
+        bad times to be returned.  Time was converted to milliseconds, then
+        to configured ticks.  Precision was lost in the millisecond
+        conversion. The fix is to first convert time to a 64-bit microsecond
+        value, then to the configured tick value. Noted by David Sidrane.
+      - clock_systimespec():  When an RTC is used clock_systimespec() must
+        subtract the basetime from the returned time.  It needs to return
+        the time since power up, no the current time.  Issue noted by Max
+        Neklyudov.
+      - AIO: correct some backward tests in aio_read() and aio_write():
+        Socket descriptors have higher numbers than file descriptors.  In
+        aio_contain(),  Copy u.ptr (void *) when initializing aioc and not
+        the case specific u.aioc_filep.  From Michal Ulianko.
+
+    * File Systems/Block Drivers/MTD:
+
+      - procfs:  Fix potential NULL pointer dereference of 'node'.  From
+        Juha Niskanen.
+      - FAT: fat_unbind() was accessing 'fs->fs_sem' after freeing the 'fs'
+        struct. From Juha Niskanen.
+      - mkfatfs:  Use DMA memory for mkfatfs when needed. This makes mkfatfs
+        use fat_dma_alloc() when CONFIG_FAT_DMAMEMORY is set. This is needed
+        to ensure mkfatfs operates with boards that use DMA for microSD.
+        From Andrew Tridgell via the PX4/NuttX repository.
+      - FAT unmount: Fix a bug in the FAT unbind() logic.  There were
+        problems with the way certain internal list handling was
+        implemented. The end result is that newly opened or cloned file
+        structures were never being added to the list of open files.  So
+        when the unmount() happens, it always looked like there were not
+        open files and a crash could ensue.
+      - FAT mounting:  Fix misthink when CONFIG_ENDIAN_BIG=y.  From Lwazi Dube.
+
+    * Common Drivers:
+
+      - CAN upper half driver: Some lines had to be reordered in the can_open
+        function otherwise the open count will only be incremented from 0 to
+        1. This caused problems when trying to open the can bus from two
+        different tasks. SourceForge Patch #46.
+
+    * Crypto:
+
+      - crypto:  Fix issues when AES support was added for the STM32L1.
+        From Juha Niskanen.
+
+    * Networking:
+
+      - Network initialization: Divide net_intiialize() into net_setup() and
+        net_initialize() to solve a chicken-and-egg problem.  net_setup()
+        must be called before up_initialize() is called so that networking
+        data structures are ready to register new network devices.
+        net_initialize() now does only timer related operations and is
+        called AFTER up_initialize() where the timers are configured.
+        Problem noted by Max Neklyudov.
+      - netdev_unregister():  Fix a list handling error.  From Max Neklyudov.
+      - Socket dup: Do not call sockfd_socket() twice.  From Juha Niskanen.
+
+    * Common Drivers:
+
+      - max11802 touchscreen:  Fix possible unmatched IRQ restore (not
+        normally a problem, but could happen in certain configurations).
+        Noted by Juha Niskanen.
+      - MMCSD SPI Multi-block transfers: ACMD23 must be preceded with CMD55
+        command as any other ACMD commands. Also, after the block reading
+        wait loop must be inserted before writing the next block of data to
+        the sd card.  From Dmitry Nikolaev via Jussi Kivilinna.
+      - MMCSD SDIO:  Fix some bad logic when file system debug is turned on:
+        Arguments to syslog were missing so that garbage was being printed.
+      - Common upper-half serial driver: Report correct number of bytes free
+        in serial buffer with FIONWRITE.  From Sami Pelkonen via Jussi Kivilinna.
+      - Pipes/Fifos: Fix zero-lenth writes to pipes/FIFOs. From Jussi Kivilinna.
+      - USB device MSC: Add NULL pointer check.  From Juha Niskanen.
+      - BCH driver: Avoid NULL pointer dereference when bch->refs  == 255.
+        From Juha Niskanen.
+      - Various drivers: The inode unlink method should not be support if
+        operations on the root pseudo-filesystem are disabled.
+
+    * ARMv7-M
+
+      - ARMv7M MPU:  Bad syntax in ARMv7-M MPU logic would cause failure to
+        write the correct value to the MPU_RASR register. From Juha Niskanen.
+
+    * Atmel SAM3/4 Drivers:
+
+      - SAM3/4 Serial TERMIOS:  A side-effect of changing serial settings
+        via TERMIOS (such as tcsetattr) is that serial interrupts were being
+        left disabled.  This is not a problem if the serial configuration is
+        changed when there are no open references to the serial device.  In
+        that case, serial interrupts are disabled and will not be enabled
+        enabled until the serial device is first opened.  But it is fatal if
+        the serial device is already opened and if there is a task waiting
+        to receive data.  In that case, the side-effect of disabling
+        interrupts is fatal:  That task is then left hanging with interrupts
+        disabled.
+      - SAM3/4 Serial: The IMR register is read-only.  This means that
+        sam_restoreints() did not actually re-enable UART interrupts
+        (Fortunately, that function was not being used up to this point).
+      - SAMA5 HSMCI:  Fix a bug in SAMA5 HSMCI.  The bitfield mask and shift
+        values were reversed resulting in a trashed value for the number of
+        blocks in the BLOCKR register.  This was sufficient to prevent DMA
+        writes from working.
+
+    * Atmel SAMA5 Drivers:
+
+      - SAMA5 Timer/Counter: Fix typos in timer/counter header file.  From
+        Bob Doiron.
+
+    * STMicro STM32 Drivers:
+
+      - STM32 PWR and RTC: Changes to support fully write protecting the
+        backup domain. N.B. stm32_pwr_enablebkp did not account for the delay
+        from enable to the domain being writable. The KISS solution is a
+        up_udelay. A more complex solution would be a negated write test
+        with restore.  From David Sidrane.
+      - STM32 SPI:  Add missing SPI callback functions to the STM32 SPI
+        driver.  From Freddie Chopin.
+      - STM32 I2C: Add missing NULL check.  From Juha Niskanen.
+      - STM32 USB device: Fix stale initialization invalidating later NULL
+        check.  From Juha Niskanen.
+      - STM32 UART: Fix RX DMA setup for UART5.  From  Jussi Kivilinna.
+      - STM32 UART: Make input hardware flow-control work with RX DMA.  From
+        Jussi Kivilinna.
+      - STM32 RTC and clock control:  The STM32F4Discovery board doesn't
+        come with a Low speed external oscillator so the default LSE source
+        for the RTC doesn't work. In stm32_rtcc.c the up_rtcinitialize()
+        logic doesn't work with the LSI. The check on RTC_MAGIC on the BK0R
+        register lead to rtc_setup() call that rightfully enables the LSI
+        clock; but the next times, when the rtc is already setup, the
+        rtc_resume() call does NOT start the LSI clock! The right place to
+        put LSE/LSI initialisation is inside stm32_stdclockconfig() in
+        stm32fxxxxx_rcc.c.  Doing this I checked the possible uses of the
+        LSI and the LSE sources: the LSI can be used for RTC and/or the
+        IWDG, while the LSE only for the RTC (and to output the MCO1 pin).
+        This change is not verifed for any other platforms.  From Leo
+        Aloe3132
+
+    * Tiva Drivers:
+
+      - Tiva GPIO driver needed small fixes in the configuration routines and
+        discovered false-positive bugs in interrupt testing: interrupts are
+        now verified to actually be working reliably. From Calvin Maguranis .
+
+    * MIPS32:
+
+      - mips32/Toolchain.mk: Current Pinguino toolchain uses the prefix p32-
+        instead of mips-.
+
+    * C Library/Header Files:
+
+      - sigaddset() and sigdelset(): Need to set errno if a bad signal
+        number is received.
+      - sfrtime():  Missing implementation of %C in sfrtime() C (was being
+        treated as %y).  From Freddie Chopin.
+      - pthread.h: Fix PTHREAD_COND_INITIALIZER.
+      - ungetc.c: Fix NULL pointer dereference in ungetc() if 'stream' was
+        NULL, 'stream->fs_oflags' was evaluated.  From Juha Niskanen.
+      - Fixes to asinh(), atanh(), and sinh():  The 'basic' expansions all
+        exhibited bad cancellation errors near zero (<= 1E-10). This can be
+        easily seen e.g. with x = 1E-30, the results are all zero though they
+        should be extremely close to x. The cutoff values (1E-5, 1E-9) are
+        chosen so that the next term in the Taylor series is negligible (for
+        double). Functions could maybe be optimized to use only first term (x)
+        and a smaller cutoff, just bigger than where the cancellation occurs
+      - localtime(): Inconsistent configuration name: CONFIG_LIBC_TZDIR vs
+        CONFIG_LIBC_TZ_TZDIR.  Former wins.
+
+    * Applications:
+
+      - Modbus:  Fix some compile problems when TCP is enabled.
