+NuttX-7.8
+---------
+
+The 108th release of NuttX, Version 7.8, was made on February 11, 2015,
+and is available for download from the SourceForge website.  Note
+that release consists of two tarballs:  nuttx-7.8.tar.gz and
+apps-7.8.tar.gz.  Both may be needed (see the top-level nuttx/README.txt
+file for build information).
+
+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.
+
+Additional new features and extended functionality:
+
+    * Core OS:
+
+      - Tickless Mode:  added limit of maximum delay that can be request
+        by the scheduler tickless logic.  This is necessary so that the
+        tickless logic does not request a delay beyond the capability of the
+        underlying hardware.  From Macs Neklyudov.
+
+    * Common Drivers:
+
+      - VFS Unlink: Add an unlink method to both the character and block
+        driver interface.  This is important because if the driver inode is
+        unlinked and there are no open references to the driver, then the
+        driver resources will be stranded.  On the unlink call, the driver
+        has the opportunity (1) check if there an any open references, and
+        if not, (2) free the driver resources.
+      - Pipes and FIFOs:  Implement the unlink method.  If the pipe/FIFO is
+        unlinked, it will marked the pipe/FIFO as unlinked.  If/when all
+        open references to the driver are closed, all of the driver
+        resources will be freed.
+      - Added an option to use the syslog'ing device as the system console.
+        This option enables a low-level, write-only console device at
+        /dev/console (similar to the low-level UART console device).  From
+        Pierre-noel Bouteville.
+
+    * File Systems/Block Drivers/MTD:
+
+      - RAM/ROM disk:  Add logic to dispose of the driver and RAM buffer
+        when the RAM disk has been unlinked and all open references to the
+        RAM disk have been closed.  Add new parameters to romdisk() to
+        specify what should be done with the RAM/ROM buffer in this case --
+        Should it be freed or not?  Changed all calls to ramdisk() to use
+        these new parameters.
+
+    * Networking:
+
+      - Add support for local, Unix domain sockets.  Support included for
+        both SOCK_STREAM and SOCK_DGRAM style local socket.
+      - UDP enhancement:  Add UDP read-ahead support.  In addition to
+        eliminating the main reason for lost UDP packets, then change
+        enables support for for poll/select on UDP sockets and also non-
+        blocking UDP sockets.  From Macs Neklyudov.
+      - SLIP interface improvements.  From Macs Neklyudov.
+      - IPv6 Neighbor Solicitation: Added logic to support verification
+        that we have the IPv6 address in the Neighbor Table before sending
+        any packets.  If not, then the Neighbor Solicitation message is
+        sent.  This feature is important because otherwise the first packet
+        sent to a remote peer will fail (it would have been replaced with a
+        Neighbor Solicitation).
+      - IPv6 Autonomous Auto-Configuration:  Added support for sending
+        ICMPv6 Router Solicitation and receiving Router advertisement.  The
+        local IPv6 address, mask, and router address are then auto-configured
+        from the response..
+      - IPv6 Router Support:  Add logic to behave like a router (if so
+        configured) only in the sense that NuttX will send the router
+        advertisement message in response to any received router solicitation
+        messages.  Thus, one NuttX node in a network can configure the IPv6
+        addresses of all other nodes in the network.
+      - Optional IPv6 address filtering added to all Ethernet drivers for
+        the all-routers multicast address. 
+
+    * Atmel AVR:
+
+      - Added architecture support for the Atmel AVR ATMega1284P MCU.  From
+        Jedi Tek'Unum.
+
+    * Atmel AVR Boards:
+
+      - Added support for the LowPowerLab MoteinoMEGA that is based on the
+        Atmel AVR ATMega1284P MCU.  From Jedi Tek'Unum.
+
+    * Atmel SAMA4:
+
+      - Add support for Tickless mode of operation for the SAM4CM platform.
+        From Macs Neklyudov.
+
+    * Atmel SAMA4 Drivers:
+
+      - Ethernet: The SAM4E Ethernet driver can now be configuration to
+        perform all network processing on the work queue.  This greatly
+        reduces the amount of interrupt level processing to service Ethernet
+        packets.
+      - SAM4E Ethernet: Add support multicast address matching and IPv6.
+
+    * Atmel SAMA4 Boards:
+
+      - SAM4E-EK: The nsh configuration now configures the Ethernet driver
+        for execution on the work thread.
+
+    * Atmel SAMA5D Drivers:
+
+      - SAMA5D4 Ethernet: The SAMA5D4 Ethernet driver can now be configuration
+        to  perform all network processing on the work queue.  This greatly
+        reduces the amount of interrupt level processing to service Ethernet
+        packets.
+      - SAMA5D3 and SAMA5D4 Ethernet: Add support multicast address matching
+        and IPv6.
+
+    * Atmel SAMA5D Boards:
+
+      - SAMA5D4-EK;  Added a configuration to testing IPv6.
+      - SAMA5D4-EK:  Converted the nsh and ipv6 configurations to configure
+        the Ethernet driver to use the work queue (vs. interrupt level
+        processing).
+
+    * Freescale KL:
+
+      - Add architectural support for the K26Z128VLH4 chip.  From Derek B. Noonburg.
+
+    * Freescale KL Boards:
+
+      - Add board support for the Freedom KL26Z board.  From Derek B. Noonburg.
+
+    * NXP LPC17xx Drivers:
+
+      - Ethernet: Add support multicast address matching and IPv6.
+
+    * SiLabs EFM32:
+
+      - Add configurable option to unconditionally enable LE clocking. Even
+        you don't use core clock LE as source for LFA or LFB, to read are
+        write any register not clocked by HFPERCLK or HFCORECLK,  HFCORECLKLE
+        should be enabled.  From Pierre-noel Bouteville.
+
+    * SiLabs EFM32 Drivers:
+
+      - EFM32 RTC:  RTC driver using BURTC. From Pierre-Noel Bouteville.
+
+    * STMicro STM32 Drivers:
+
+      - AES: Add driver for STM32L162XX AES peripheral.  From Juha Niskanen.
+      - Ethernet: The STM32 Ethernet driver can now be configuration to
+        perform all network processing on the work queue.  This greatly
+        reduces the amount of interrupt level processing to service Ethernet
+        packets.
+      - Ethernet: Add support multicast address matching and IPv6.
+
+    * STMicro STM32 Boards:
+
+      - Added an IPv6 configuration for the STM32F4-Discovery board (with the
+        STM32-DISCO_BB base board).
+      - Converted all STM32F4-Discovery configurations (with base board) to
+        configure the Ethernet driver to use the work queue (vs. interrupt
+        level processing).
+
+    * TI Tiva Drivers:
+
+      - Added support for TM4C123G timers.  From Calvin Maguranis.
+      - Added a Tiva ADC driver.  From Calvin Maguranis.
+
+    * TI Tiva Boards:
+
+      - Added TM4C123G timers on the TM4C123G Launchpad.  From Calvin Maguranis.
+      - Added Tiva ADC support to the TM4C123G-Launchpad.  From Calvin Maguranis.
+
+    * C Library/Header Files:
+
+      - Math Library: Added support for inverse hyperbolic functions,
+        isfinite(), error functions, nan(), copysign(), and trunc()
+        functions.  From Brennan Ashton.
+
+    * Applications:
+
+      - apps/examples/ustream:  Add a simple test of Unix domain stream
+        sockets.
+      - apps/examples/udgram:  Add a simple test of Unix domain datagram
+        sockets.
+      - apps/netutils/netlib:  Add utilities to convert to/from prefix
+        lengths from/to 128-bit network masks.
+      - apps/nshlib: Modify the NSH IPv6 ifconfig command to show the more
+        standard post-pended prefix value, rather than the full 128-bit
+        netmask.
+
+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:
+
+      - Work Queues:  Fix a backward calculation when determining the time
+        to the next interesting event. .  From Liio Chen via the PX4
+        repository.
+      - clock_systimespec():  Fixes for compilation errors in certain
+        configurations.  From Macs Neklyudov.
+
+    * Graphics
+
+      - Fixed a problem with one of the font files.  From Pierre-noel Bouteville.
+
+    * Networking:
+
+      - IOB Deadlock: There were issues with the TCP write-ahead buffering
+        if CONFIG_NET_NOINTS was enabled:  There is a possibility of
+        deadlocks in certain timing conditions:  The network should never
+        wait for TCP read-ahead buffering space to be available.  It should
+        drop the packets immediately if no buffering is available. This was
+        fixed by duplicating most of the IOB interfaces:  The versions that
+        waited are still present (like iob_alloc()), but now there are non-
+        waiting versions of the same interfaces (like iob_tryalloc()).  The
+        TCP read-ahead logic now uses only these non-waiting interfaces.
+      - TCP Deadlock: Fix another deadlock when CONFIG_NET_NOINTS is enabled.
+        tcp_write_buffer_alloc() calls sem_wait() with network locked.  That
+        worked if CONFIG_NET_NOINTS was not defined because interrupts are
+        automatically restored when the wait happens.  But with
+        CONFIG_NET_NOINTS=y, the wait blocks with the network locked -- bad
+        style and also can lead to a deadlock condition.
+      - ARP response waiting: Fixes another CONFIG_NET_NOINTS issue.  When
+        called sem_timedwait() with the network locked, the network stays
+        locked while we wait which is not what we want (without CONFIG_NET_NOINTS,
+        interrupts are re-enabled while we wait and all is well).
+      - TCP accept():  Fix a major TCP bug introduced with the NuttX-7.7
+        IPv6 changes:   Some connection logic was reordered; setting the
+        socket as 'connected' got moved to BEFORE the point where the check
+        was made if the socket was already connected.  The resulting behavior
+        was odd:  Telnet would connect, but then when you exit and reconnect,
+        it would fail to connect.  But then if try again, it would connect
+        okay. So the symptom was connect-fail-connect-fail-...
+      - Lots of build problems introduced into multiple NIC support with the
+        IPv6 changes of NuttX-7.7.   Many places where conditional logic based
+        on CONFIG_NETDEV_MULTINIC is  confused with CONFIG_NET_MULTILINK.
+        Lots of code changed with IPv6 that was never compiled with MULTINIC
+        enabled.
+
+    * Common Drivers:
+
+      - Pipes and FIFOs: Fix a race condition between FIFO buffer operations
+        and the opening and closing of FIFOs which necessary when the FIFOs
+        are used to support Unix domain, datagram sockets.  The default
+        policy is the deallocate FIFO buffering when the last client closes
+        the pipe.  When when used for datagram communications, packets left
+        in the FIFO will be lost. Some like UDP read-ahead is needed:  The
+        buffered data in the FIFO needs to be retained until the reader gets
+        a chance to re-open the FIFO.  Added an ioctl (PIPEIOC_POLICY) to
+        control the buffer policy.  Default (0) is the legacy behavior; Unix
+        domain datagram logic sets the alternative policy so that the packet
+        data persists after the FIFO is closed.
+      - RAMTRON:  Table of parts is not terminated properly if
+        CONFIG_RAMTRON_FRAM_NON_JEDEC is not defined.  Noted by David
+        Sidrane.
+
+    * All Archtectures:
+
+      - Removed all occurrences of up_maskack_irq() that disables interrupts
+        with up_ack_irq() that only acknowledges the interrupts.  This is only
+        used in interrupt decoding logic.  Also remove the logic that
+        unconditionally re-enables interrupts with the interrupt exits.  This
+        interferes with the drivers ability to control the interrupt state.
+        This is a necessary, sweeping, global change and unfortunately
+        impossible to test.
+
+    * ARM
+
+      - ARMv7-A and ARMv7-M memcpy(): Optimized ARM assembly language
+        memcpy's were not returning a value in R0 they are required to do.
+        From David Sidrane.
+      - ARMv7-A interrupt handler should not automatically re-enable interrupts
+        on interrupt return.  That interferes with the driver's ability to
+        manage interrupts.  Analogous change made to all other architectures
+        as well (ARM7, ARM9, HC, SH, x86, z16, z80, etc,.  See above.).
+
+    * STMicro STM32:

+      - GPIO Interrupts: Disabling any of EXTI 5-9 interrupts was disabling
+        interrupts for all EXTI 5-9. Same issue with EXTI 10-15.  From Jussi
+        Kivilinna.
+
+    * STMicro STM32 Drivers:
+
+      - RTCC:  Fix for recent changes that caused compilation failrues with
+        STM32L15XX configurations.  From Jussi Kivilinna.
+      - SPI: The source clock for SPI 4,5, and 6 should be PCLK2, not PCLK1
+        (for F411, F427, and F429).  Per David Sidrane.
+
+    * C Library/Header Files:
+
+      - execl():   Fix bad logic in counting the number of arguments. 
+        execl() parameter passing could never have worked.  Noted by
+        Pierre-noel Bouteville.
+
+    * Applications:
+
+      - Fix for building with parallel make. Build-server sometimes failed
+        'make -j24' with errors in the builtin line or or sometimes silently
+        succeeds but generated builds that contain a random subset of
+        configured NuttX applications. There are two root causes for this:
+        (1) Recipes for building builtin_list.h and builtin_proto.h are
+        not linearizable, and (2) Nothing ensures that 'make context' is run
+        first for apps/builtin.  This change address both issues. From Juha
+        Niskanen.
