	  ioctl with radio. Moves all functionality from libradio to libmac.
	  From Anthony Merlino (2017-05-05).
	* wireless/wapi: wpa_driver_wext_associate() now accepts a
	  configuration parameter that can be used to specify the wireless
	  properties (2017-05-06).
	* nshlib:  NSH now has configuration options to select the
	  wireless properties.  It builds the configuration structure and
	  passes this to wpa_driver_wext_associate() so that it will set the
	  network as configured (2017-05-06).
	* Add platform files for nucleo-l452re and nucleo-l496zg.  From Juha
	  Niskanen (2017-05-08).
	* wireless/ieee802154:  Adds rxonidle attribute helpers.  From Anthony
	  Merlino (2017-05-08).
	* wireless/ieee802154:  Adds sniffer functionality back in to I8SAK
	  app.  From Anthony Merlino (2017-05-08).
	* NSH wireless setup:  Move call to nsh_associate().  It should be
	  possible to associate with an AP when DHCPC is disabled (2017-05-09).
	* Fix some calls to task_create():  argv[0] is the first parameter, not
	  the name of the task (2017-05-09).
	* wireless/ieee802154: Restructures i8sak app and adds blaster
	  functionality.  From Anthony Merlino (2017-05-09).
	* examples/configdata: add stacksize and priority.  From Juha Niskanen
	  (2017-05-10).
	* Bitbucket Issue 5:  I found an unexpected behavior in apps/
	  configuration generation. Adding external symbolic link in apps/
	  directory and using Make.defs for Kconfig generation, Kconfig file
	  has a wrong path in the source argument. It contains original dir
	  path outside of the source tree instead path to sub-directory in
	  apps/.  The problem is connected with make/system symbolic link path
	  resolution.  Corrected by a patch submitted by Artur Madrzak with
	  Issue 5 (2017-05-11).
	* Bitbucket Issue 5, apps build system: The previous patch wasn't
	  complete, it was just idea how to resolve issue.  Please, find
	  attached issue5.patch to resolve it. It can be applied on top current
	  apps/master. From Artur Madrzak (2017-05-12).
	* Fix the new can.h header location.  From Alan Carvalho de Assis
	  (2017-05-12).
	* Fix libcanard github download link to get it compiling correctly.
	  From Alan Carvalho de Assis (2017-05-12).
	* Fix to use the new canardInit() function.  From Alan Carvalho de
	  Assis (2017-05-12).
	* apps/platform:  Create gnu/ subdirectory that contains the one and
	  only GNU C++ initialization function.  Remove all other C++
	  initialization functions (2017-05-13).
	* Move up_cxxinitialize() prototype from nuttx/include/nuttx/arch.h to
	  apps/include/platform/cxxinitialize.h (2017-05-13).
	* apps/examples/nettest: Fix an error in pre-processor expression
	  (2017-05-13).
	* wireless/ieee802154: i8sak adds event handling from MAC char driver.
	  From Anthony Merlino (2017-05-16).
	* apps/examples/mtdpart: Prevent part array overflow.  mtdpart examples
	  create partions and allocate from 1 index not a 0 index to part[]
	  array. This cause buffer overflow for part array.  This change fixes
	  this problem.  From  EunBong Song (2017-05-17).
	* apps/examples/can:  Fix can example app to print data when
	  CONFIG_EXAMPLES_CAN_READ is defined.  From Alan Carvalho de Assis
	  (2017-05-17).
	* apps/: Make more globals static to avoid name clashes.  From Juha
	  Niskanen (2017-05-19).
	* Ensure netlib will not be broken when setip will not bring the
	  network up anymore.  From Sebastien Lorquet (2017-05-19).
	* DHCPC: Remove hard-coded interface device.  Now passed as a parameter
	  to dhcpc_open().  From Sebastien Lorquet (2017-05-19).
	* nshlib: Fix a resource leak in cmd_hexdump().  From Nobutaka
	  Toyoshima (2017-05-22).
	* wapi: add basic wapi_event_stream_extract implementation.  From Simon
	  Piriou (2017-05-21).
	* apps/system/dhcpc:  Add a command to renew or establish a lease on an
	  IPv4 address (2017-05-21).
	* apps/system/ntpc:  Add a command to start or stop the NTPC daemon
	  (2017-05-21).
	* apps/system/dhcpc: Add missing argument of fprintf (2017-05-21).
	* apps/nshlib:  Add a new option CONFIG_NSH_NETLOCAL that will suppress
	  some built in operations and will support manual configuration of a
	  wireless network (2017-05-21).
	* apps/system/ramtest: Make stacksize and priority conigurable
	  (2017-05-22).
	* The dedicated windows tool at tools/mkkconfig.bat uses $APPSDIR,
	  which is not a windows shell variable, and is left uninitialized, but
	  in fact should be the current directory.  From Sebastien Lorquet
	  (2017-05-22).

7.22 2017-09-06 Gregory Nutt <gnutt@nuttx.org>

	* apps/system/composite: Update to apps/system/composite assocated with
	  big changes to the composite device logic.  From Frank Benkert
	  (2017-06-01).
	* wireless/ieee802154: Modifies i8 to support running various routines.
	  From Anthony Merlino (2017-06-14).
	* wireless/ieee802154: Rewrites i8sak to be test CLI for IEEE 802.15.4
	  MAC layer.  From Anthony Merlino (2017-06-14).
	* NSH network initialization: Fix some ieee 802.15.4 initialization
	  logic.  It should not set the saddr or panid; those cannot be
	  hard-coded but must come from the coordinator.  Re-factor a function
	  that has gotten too big and too complex.  Do not set the IP address
	  for 6loWPAN.  The 6loWPAN stack uses IP address that derive from the
	  ieee 802.15.4 addressing and cannot be (safely) configured by the
	  user (2017-06-17).
	* i8sak:  Missing newline in fprintf output (2017-06-18).
	* correct copy-paste typo in comments in composite_main.c  From Oleg
	  Evseev (2017-06-18).
	* Switches IEEE 802.15.4 based code to using byte arrays instead of
	  uint16_t values for short address and PAN ID.  From Anthony Merlino
	  (2017-06-19).
	* fix copy-paste typo in nsh_usbconsole.c.  From Oleg Evseev
	  (2017-06-19).
	* examples/udp: Add configurable network device name; Add option to
	  suppress network initialization which is not needed if started by NSH
	  or for 6LoWPAN (2017-06-19).
	* nshlib: fix size of 6LoWPAN extended address (2017-06-18).
	* examples/udp:  Fix registration as a built-in program; Change some
	  naming to make room for a second target.  Current one endpoint is the
	  target and one is the host.  This will (eventually) allow two targets
	  to be both endpoints of the test.  Change build so that both server
	  and client can be on a target, rather than one on the target one on
	  the host PC.  Server IP address may not be provided on the command
	  line (2017-06-19).
	* examples/smart: Fix some compilation errors.  Obviously this test has
	  not been used in a LONG time (2017-06-20).
	* examples/udp:  Port numbers need to be configurable to work with
	  6LoWPAN.  Need to bind the client socket to a port number.  This was
	  not required before so is a apparently a change in the UDP packet
	  dispatch logic (2017-06-20).
	* ieee802154: Changes to support beacon-enabled networks.  From Anthony
	  Merlino (2017-06-21).
	* wireless/ieee802154: Adds option to make it easy to send large frame
	  for testing purposes.  From Anthony Merlino (2017-06-21).
	* examples/udp:  Renaming some files to prevent name collision in
	  libapps.a.  Fix naming of a configuration setting (2017-06-23).
	* examples/nettest:  Renaming some files to prevent name collision in
	  libapps.a and to prepare to support target boards on both ends of the
	  test.  Separate out network initialization so that it may,
	  eventually, be used by both a target server and a target client.  Fix
	  client/server naming confusion; add command line option to select the
	  server address on the target.  Add support for both enpoints on
	  target boards vs. one on a target and one on the host PC
	  (2017-06-23).
	* system/dhcpc:  The DHCPC renew command did not build correctly due to
	  naming problems.  Noted by Masayuki Ishikawa (2017-06-23).
	* examples/nettest: Fixes for building with loopback device again after
	  the last changes (2017-06-23).
	* examples/nettest:  The send buffer size is now a configuration option
	  (2017-06-24).
	* examples/udp and examples/nettest: Fix some naming collisions;
	  examples/nettest:  Fix some build issues with two targets
	  (2017-06-25).
	* ieee802154: Adds scan command.   From Anthony Merlino (2017-06-25).
	* ieee802154: Minor fix to setup logic for i8sak.  From Anthony Merlino
	  (2017-06-25).
	* ieee802154: start of scan/beacon-enabled network.  From Anthony
	  Merlino (2017-06-26).
	* netutils/telnetc:  This a port of libtelnet to NuttX (2017-06-26).
	* system/telnet:  Add Telnet Chat deamon and and client from libtelent
	  (2017-06-26).
	* NSH library:  Add a Telnetd command.  This is needed when network
	  initialization is deferred.  In that case, telnet daemon cannot be
	  started until the network is finally initialized.  The telnetd
	  command was added just for that case:  So that the telnet daemon can
	  be started from the NSH command line after the network is configured
	  (2017-06-26).
	* revise some of the state handling in the previous commit
	  (2017-06-26).
	* system/telnet: POLL must not be disabled in configuration.  Telnet
	  client port argument is no optional (2017-06-27).
	* netutils/telnetd and users of telnetd:  Add support for IPv6
	  (2017-06-27).
	* ieee802154/i8sak: Adds coordinfo command allowing you to poll various
	  attributes related to the coordinator.  From Anthony Merlino
	  (2017-06-27).
	* i8sak:  Need to increment the next_saddr after each successful
	  association (2017-06-29).
	* i8sak:  Add a option to retry on failures to the assoc command
	  (2017-06-29).
	* apps/examples/thttpd:  Remove the netstats demo.  This depends on an
	  illegal function call and cannot be supported.  That example could be
	  replaced with logic that uses the procfs network entries as was done
	  for NSH which had the same issue.  But I am too lazy to implement
	  that (2017-07-01).
	* i8sak: Adds reset command to reset the MAC layer.  Adds option to
	  assoc command -t to specify how long to wait for a response from the
	  Coordinator.  From Anthony Merlino (2017-07-01).
	* Eliminate a warning when both Ethernet and 6LoWPAN are enabled;
	  improve some naming (2017-05-02).
	* ieee802154: Adds reset command, adds resp_waittime option to
	  associate, and a few other minor tweaks.  From Anthony
	  Merlino(2017-07-02).
	* NSH library: Fix build break in nsh_command.c with IPv4/IPv6 dual
	  stack.  From Masayuki Ishikawa (2017-07-04).
	* apps/examples/keypadtest: REMOVED and warehoused in the Obsoleted
	  repository.  This was just a bad clone of apps/examples/hidkbd for a
	  keypad driver that was removed years ago.  It also uses illegal
	  function calls into the OS.  So it has no purpse:  It is
	  redundant, it uses illegal interfaces, and is a test for non-existent
	  code (2017-07-04).
	* tools/mkkconfig.bat: Use %cd% instead of %~dp0 for usage of APPSDIR
	  in this batch file (2017-07-05).
	* system/dhcpc: Fix warning about renew_main.o appear twice in rule
	  (2017-07-05).
	* tools/mkkconfig.bat:  Remove quotes in echo.  These were begin
	  Echo'ed and generating double quots in the output.  From Jeff
	  (2017-07-05).
	* Windows build fixes:  tools/mkkconfig.bat - switch APPSDIR path to
	  use forward slashes for kconfig-frontends. interpreters/ficl -
	  Reorder some targets that causes GNUwin32 make to behave badly.  From
	  Jeff (2017-07-06).
	* platform/Makefile: More attempts to fix for Windows native build.
	  Backslash as a delimiter causes problems in pattern subsitutions
	  (2017-07-06).
	* apps/examples/ipforward: Add beginning of an IP forwarding example
	  using only TUN devices.  Test extended to test forwarding of ICMPv6
	  multicast messages.  Completes code for apps/examples/ipforward.
	  Still untested (2017-07-09).
	* apps/netutils/tftpc: Missing header file causes errors in some
	  configurations (2017-07-10).
	* Socket I/F: Cleanup for good CONFIG_NET_PKT build (2017-07-14).
	* netutils/netlib:  Fixes to work when only USRSOCK is enabled
	  (2017-07-14).
	* apps/system/composite:  Remove CDC/ACM and MSC configuration logic.
	  This belongs in the OS composite initialization.  Add and argument so
	  that you can select the USB composite configuration to be attached.
	  Restore USB tracing; remove unused field in a structure.  Remove
	  configuration settings that are no longer used.  Fix configuration
	  selecting.. was setting the port number, not the configure ID.  Also
	  add a configuration option to select the default configuration
	  (2017-07-15).
	* apps/system/composite: Add a configuration option to the boardctl()
	  calls to support multiple composite device configurations dynamically
	  (2017-07-16).
	* i8sak: Minor formatting fix.  From Anthony Merlino (2017-07-10).
	* wireless/ieee802154/i8sak: Minor setting changes.  From Anthony
	  Merlino (2017-07-17).
	* ieee802154/i8sak:  Adds command to trigger regdump of radio.  From
	  Anthony Merlino (2017-07-18).
	* apps/system/composite:  Remove references to USBMSC.  There still
	  dependencies on CDC/ACM in the serial USB trace output.  That really
	  should be removed (2017-08-21).
	* netutils/ftpc:  Fix some memory leaks.  From Boris Astardzhiev
	  (2017-07-27).
	* Implement powermonitor example for ltc4151 current and voltage
	  monitor.  From Giorgio Groß (2017-07-28).
	* NSH: Misc changes needed for PktRadio support (2017-07-30).
	* examples/nettest/:  Loopback option should be available in Kconfig
	  for PktRadio (2017-08-01).
	* apps/netutils/netlib:  Add support for PktRadio IOCTL commands
	  (2017-08-02).
	* NSH library: Extend ifconfig command so that it can set variable
	  length packet radio addresss (2017-08-02).
	* netutils/netlib: Fix netlib_nodaddrconv() so that its return type is
	  the same as other address conversion functions.  NSH: Correct parsing
	  of ifconfig so that you can specify the HW address without specifying
	  the IP address (2017-08-02).
	* apps/examples/udp:  Enable testing with the broadcast address
	  (2017-08-08).
	* Remove references to obsoleted CONFIG_NETDEV_MULTINIC and
	  CONFIG_NETDEV_MULILINK (2017-08-08).
	* NSH library:  Update addroute and delroute command.  The would
	  support either IPv4 or IPv6, but not both.  Allow expression of the
	  netmask in IPv4 CIDR or IPv6 slash notation.  This really reduces the
	  pain of using the commands, especially for IPv6 (2017-08-10).
	* NSH Library: Add a route command that will dump the content of
	  routing table (2017-08-11).
	* apps/netutils/tftpc depends on CONFIG_NET_IPv4 (2017-08-12).
	* Application.mk:  Add the .PRECIOUS target to prevent libapps.a from
	  being deleted when the make is interrupted (2017-08-12).
	* apps/examples/nximage: Remove unused global variable (2017-08-12).
	* netutils/thttpd: Fix a malformed if condition detected by GCC 6.x.x
	  (2017-08-12).
	* All Makefiles:  Add .PRECIOUS: apps/libapps.a to every Makefile.
	  Hopefully this will end awkward problems when you Control-C out of a
	  build and libapps.a is deleted (2017-08-13).
	* The last change added .PRECIOUS: $(BIN) to everyway Makefile in hopes
	  the libapps.a will not be deleted on Control-C (unproven so far).
	  However, $(BIN) may contain back slashes in some build platforms and
	  that causes problems for make:  It can't handle the backslashes in
	  the .PRECIOUS dependency list.  $(BIN) replaced with ../../libapp.a,
	  where the number of ../ depends on the depth of the Makefile in the
	  apps/ source tree (2017-08-13).
	* netutils/netlib: Add a helper to decode short addresses
	  (2017-08-18).
	* apps/examples/pf_ieee802154:  Add for testing PF_IEEE802154 sockets.
	  Add PANID to command line options; Cannot bind to address zero...
	  There is no counterpart to INADDR_ANY for these radios (not now at
	  least) (2017-08-19).
	* Changes to netlib and nsh so that you build build with PF_IEEE802154
	  enabled and 6LoWPAN disabled (2017-08-20).
	* netutils/netlib: If only PF_IEEE802154 socket family is enabled, then
	  must use SOCK_DGRAM (2017-08-21).
	* NSH:  Add conditions so that ifconfig and ifup will not be disabled
	  if we are using only PF_IEEE802154 (2017-08-21).
	* dhcpd: Prevent buffer overflow in dhcpd_addoption.  offset represents
	  distance from start of option buffer.  So this should be changed
	  current option pointer minus start of buffer.  From EunBong Song
	  (2017-08-25).
	* apps/examples/nsh: Remove APPNAME, PRIORITY, and STACKSIZE settings
	  from Makefile to avoid showing nsh in Builtin Apps.  From Masayuki
	  Ishikawa (2017-08-26).
	* examples: add DAC example.  From Juha Niskanen (2017-09-1).

7.23 2017-12-04 Gregory Nutt <gnutt@nuttx.org>

	* examples/ostest: sem_open() now returns SEM_FAILED in the event of a
	  failure (2017-09-08).
	* examples/adc: Fix g_adcstate.count initialization.  From Masayuki
	  Ishikawa (2017-09-11).
	* examples/fb:  Flesh out the framebuffer driver test.  examples/fb:
	  Add a simple test for the framebuffer character driver.  This initial
	  commit just verfies some interfaces and initialization logic.  Still
	  need to add to graphics update logic (2017-09-12).
	* Rename CONFIG_AUDIO_DEVICES to CONFIG_DRIVERS_AUDIO to conform better
	  to the evolving configuration naming standard (2017-09-12).
	* examples/fb:  Extend test to include 1-bpp monochrome (2017-09-13).
	* Added a simple reader example for the LIS3DSH acceleration sensor on
	  STM32F4Discovery.  From Florian Olbrich (2017-09-14).
	* wireless/ieee802154/i8sak: Adds socket interface support. You can now
	  use both socket or char driver to control the MAC layer.  From Anthony
	  Merlino (2017-09-15).
	* wireless/ieee802154/i8sak:  Fixes several bugs.  Adds sniffer port
	  option and a few other get/set parameters.  From Anthony Merlino
	  (2017-09-15).
	* i8sak: Updates README to include details about socket interface and
	  new addressing setup and fixes warning.  Fix warning about
	  uninitialized variable.  From Anthony Merlino (2017-09-15).
	* apps/examples/apa102: Add a Rainbow example for APA102 LED Strip.
	  From Alan Carvalho de Assis (2017-09-18).
	* netutils/netlib:  Add netlib_ipv6adaptor() and netlib_ipv4adaptor()
	  (2017-09-19).
	* netlib_ipv[4|6]adaptor: Add a check to handle the case where the
	  network device configuration changed asynchronously and the second IOCTL
	  returns more data than the allocated buffer (2017-09-20).
	* apps/netutils/netlib:  Add helpers for reading the routing table:
	  netlib_read_ipv4route() and netlib_read_ipv6route() (2017-09-20).
	* apps/netutils/netlib:  Add new utilities netlib_ipv[4|6]router() that
	  can be used to determine the IP address of a router that would be used
	  some some destination IP address that is not locally accessible
	  (2017-09-20).
	* apps/netutils/netlib:  netlib_ipv[4|6]adaptor() will now use the new
	  routing table interfaces if they are available:  If the destination IP
	  address does not correspond to the network served by any device, then
	  the address of the router that should get us to the correct sub-net is
	  is determined.  Then the network adaptor that can communicate with the
	  that router has the IP address that will returned (2017-09-20).
	* apps/examples/flowc:  Add a simple test of serial hardware flow control
	  (2017-09-23).
	* apps/examples/qencode: The QENCODER name was changed to
	  SENSORS_QENCODER fix it here.  From Alan Carvalho de Assis (2017-09-24).
	* nshlib/nsh_parse.c: Avoid truncating the strcmp result into a unsigned
	  char variable.  nshlib/nsh_netcmds.c: Check for valid hostip before
	  using it.  nshlib/nsh_ddcmd.c: Fix resouce leak when 'if=' or 'of='
	  params are repeated in the command line.  For example:
	    - dd if=/dev/null if=/dev/zero of=/dev/null or
	    - dd if=/dev/zero of=/dev/zero of=/dev/null
	  From Bruno Herrera (2017-09-25).
	* nshlib/nsh_netcmds.c: Fix a compilation error when IPv4/IPv6 dual
	  stack is enabled.  From Masayuki Ishikawa (2017-09-26).
	* apps/examples/flowc:  Add a delay between received packets in order to
	  force input flow control (2017-09-26).
	* apps/examples/flowc: Fix some errors in receiver's verificationg
	  logic.  Add a 'canned' data file so that we don't need to deal with the
	  sender program; we can just 'cat' the canned data file (2017-09-26).
	* apps/examples/flowc:  Add some syslog output to flush the syslog
	  interrupt buffer (2017-09-27).
	* apps/examples/flowc: Small improvement to break line if more than 80 .
	  were printed.  From Alan Carvalho de Assis (2017-09-27).
	* apps/examples:  In elf and nxflat examples, remove low-level
	  interfaces and replace with call to exec() (2017-10-02).
	* examples/elf and nxff: Won't build with CONFIG_BUILD_KERNEL because
	  the interface exec() is not available in that configuration.  Also,
	  remove a stray comma and a stray semacolon in examples/pty_test/Kconfig
	  and examples/random/Kconfig (2017-10-06).
	* Add powerled driver example.  From Mateusz Szafoni (2017-10-08).
	* examples/ostest:  Works around a bug in printf() when cancellation
	  points are enabled.  printf() is a cancellation point because it calls
	  write().  This is correct according to OpenGroup.org.  However, printf
	  holds the stdio library semaphore when it is canceled and this leaves
	  the semaphore in a bad state.  No fix for the printf bug yet (2017-10-10).
	* examples/ina219: A simple infinite loop that polls the INA219 sensor
	  and displays the measurements.  From Sebastien Lorquet (2017-10-11).
	* examples/ostest: Extend cancellation test to make sure that cancelable
	  threads waiting on a message queue or on a signal can be canceled
	  (2017-10-12).
	* netutils/ftpc:  Fix some crazy comparisons to determine is a file is
	  an absolute path.  Noted by Anthony Merlino (2017-10-13).
	* examples/nx:  The NX example no longer supports single user mode
	  (2017-10-14).
	* examples/nxtext:  The nxtext example no longer supports single user
	  mode (2017-10-14).
	* examples/lcdrw:  Remove this example.  It violates the portable OS
	  interface and cannot be retained (2017-10-14).
	* graphics/traveler:  Restore most of what was removed in the previous
	  commit.  That non-standard logic is currently needed by the simulation.
	  It should be replaced with use of a framebuffer driver.  No longer
	  supports single user graphics mode (2017-10-14).
	* examples/nxhello now supports only multiuser mode (2017-10-14).
	* examples/nximage now supports only multiuser mode (2017-10-14).
	* system/lm75:  Fix a naming error in a dependency.  From Alan Carvalho
	  de Assis (2017-10-14).
	* examples/nxlines now supports only multiuser mode (2017-10-14).
	* exampls/nxhello:  Increase the amount of time that the text is
	  displayed before erasing it (2017-10-15).
	* Add -n samples to lm75 app and replace Centigrade with Celsius.  From
	  Alan Carvalho de Assis (2017-10-15).
	* graphics/traveler: Convert to use the framebuffer driver (2017-10-16).
	* examples/alarm: add options for reading alarm value and canceling it.
	  From Juha Niskanen (2017-10-17).
	* apps/fsutils/mkfatfs:  Move mkfatfs from the OS to here.  Not fully
	  integrated on the intial commit (2017-10-20).
	* apps/examples/adps9960:  Add ADPS-9960 example.  From Alan Carvalho de
	  Assis (2017-10-23).
	* This commit eliminates the ping command from NSH and replaces it with
	  a ping 'built-in' at apps/system/ping.  The original NSH version of ping
	  violated the portable POSIX interface and, hence, had to be removed.
	  The new system/ping command uses the new IPPROTO_ICMP AF_INET datagram
	  sockets to implement ping (2017-10-23).
	* apps/system/ping6:  Use inet_ntop() to improve the appearance of the
	  ping6 IPv6 address output.  Fix a typo and also a place where = used
	  when == intended.  This commit removes the ping6 command from NSH and
	  replaces it with the apps/system/ping6 built-in command.  The NSH ping6
	  command had to be removed because it violated the portable POSIX OS
	  interface.  The apps/system/ping6 command uses the sem-standard
	  IPPROTO_ICMP6 socket interface (2017-10-24).
	* apps/nshlib:  ifconfig improvements.  From Anthony Merlino (2017-10-24).
	* nshlib:  mount command no long uses the non-standard OS interface
	  foreach_mountpoint().  Now simply cats /proc/fs/mount when there are no
	  arguments to the mount command (2017-10-26).
	* nshlib:  df command no long uses the non-standard OS interface
	  foreach_mountpoint().  Now simply cats /proc/fs/blocks or /proc/fs/usage
	  (2017-10-26).
	* Fix parsing of empty strings when CONFIG_NSH_CMDPARMS is not defined.
	  Problem noted by Juha Niskanen (2017-10-27).
	* apps/canutils/libobd2:  Add libobd2 for NuttX.  From Alan Carvalho de
	  Assis (2017-10-28).
	* apps/examples/obd2:  Add OBD2 example application.  From Alan Carvalho
	  de Assis (2017-10-28).
	* include/netutils/netlib.h:  Broaden socket definitions of previous
	  commit.  Add definitions needed when only local Unix domain sockets are
	  supported (2017-10-30).
	* apps/examples/userfs:  Add a test case for verifying UserFS
	  (2017-10-31).
	* Fixed i2ctool write operation in `no restart` mode (flag `-n`).  It
	  seems that I2C driver has changed a bit since i2ctool was written, so
	  now i2ctool sends repeated start even if `no restart` flag (-n) was
	  passed to it.  From Dmitriy Linikov (2017-11-01).
	* Fixed misprint in cmd_wget.  From Dmitriy Linikov (2017-11-01).
	* apps/examples/userfs:  Fix bad logic in test stat() implementation
	  (2017-11-01).
	* i8sak: Changes 'notif' to 'primitive' corresponding to the changes in
	  the Kernel.  From Anthony Merlino (2017-11-01).
	* Adds i8shark, a sniffer "adapter" that captures all 802.15.4 traffic,
	  packages it into a Wireshark ZEP packet, and sends it to a host running
	  Wireshark  From Anthony Merlino (2017-11-01).
	* apps/examples/userfs:  Fix check for open with write+append mode
	  (2017-11-01).
	* apps/fsutils/mkfatfs:  When fsutils/mkfats was split off from the
	  operating system, there were a few dangling things left.  Some
	  references to functions in the OS (which are not available in the
	  protected and kernel modes) and several types and function prototeypes
	  that don't exist is apps/fsutils/mkfatfs (2017-11-02).
	* Fixed the compilation of nsh_routecmds.c, broken after commit
	  6b9d23c6aa0247c701acf1d0ecdaececf546342a.  From Dmitriy Linikov
	  (2017-11-03).
	* include/netutils/netlib.h:  In order to avoid pre-processing warnings,
	  NETLIB_SOCK_FAMILY must always be assigned a value, even if there is no
	  real meaning value for it (2017-11-03).
	* i8sak: Channel setting is now saved locally, so when performing a
	  startpan or assoc, the channel previously set is still used, even though
	  the MAC layer gets reset.  Also fixes a few build issues.  From Anthony
	  Merlino (2017-11-03).
	* examples: add SMPS driver example.  From Mateusz Szafoni (2017-11-05).
	* smps, powerled examples: fix floating point format in printf.  From
	  Mateusz Szafoni (2017-11-05).
	* apps/examples/userfs:  Handle the O_TRUNC open flag.  Fixes a bug with
	  double freeing open data when dup'ed files are closed (2017-11-06).
	* apps/examples/ltdc:  Remove apps/examples/ltdc.  It violates the
	  portable POSIX interface by calling directly into OS code (2017-11-06).
	* FTP: Adds support for IPv6 and fixes various transfer issues.   From
	  Anthony Merlino (2017-11-06).
	* netutils/ftpc:  Eliminate warnings about types of inputs to
	  netlib_ipv4adaptr() and about ftp_cmd_pasv() being defined but not used
	  (2017-11-12).
	* apps/system/free:  Removed because it violates the portable POSIX OS
	  interface (2017-11-13).
	* apps/nshlib:  The free commands no longer used mallinfo() to get the
	  state of the use heap.  Two reasons:  That is not useful information in
	  the kernel build.  And (2) there are other memory resources of interest
	  in other configurations such as the Kernel heap in PROTECTED and KERNEL
	  builds, and the prog mem uses when FLASH is used to hold modifiable
	  data.  The free command has been extended to just dump the content of
	  procfs entries and to include all of these other memory resources of the
	  procfs entries are available (2017-11-13).
	* apps/nshlib:  Big simplification of last change.  /proc/kmm, umm, and
	  progmem have been replaced with a single procfs file called
	  /proc/meminfo.  The NSH free command now degenerates to a simple dump of
	  /proc/meminfo (2017-11-13).
	* apps/graphics/pdcurs34:  This commit brings the basic public domain
	  pdcurses library into NuttX.  This library is complete but not yet
	  usuable because it still requires the NuttX interfacing code needed hook
	  pdcurses into the NuttX graphics drivers.  Also test cases are needed to
	  verify the pdcurses integration (2017-11-17).
	* apps/examples/pdcurses:  Bring in pdcurses demos and make them conform
	  to the NuttX coding style (not yet hooked into the build system)
	  (2017-11-18).
	* apps/graphics/pdcurs34:  Extend configuration to select the font size
	  (2017-11-18).
	* apps/example/pdcurses:  Add logic to build one of the several pdcurses
	  demo/test programs (2017-11-18).
	* apps/graphics/pdcurs34/nuttx:  Completes first cut at framebuffer
	  rendering logic.  Add NuttX framebuffer color managment and beginning of
	  some rendering logic (2017-11-19).
	* apps/examples/pdcurses/: Fix a few more bugs found in testing;  Brings
	  in the remaining pdcurses demo programs (2017-11-19).
	* apps/graphics/pdcurs34:  Add support for discrete joystick input.
	  This is sufficient to get through all menuing tests that do not require
	  text input (2017-11-22).
	* apps/graphics/pdcurs34:  Add support for greylevels vs. RGB.  Define
	  pdc_color_t based on pixel depth, not on specific color format.  Need to
	  set the global COLORS or else all displays on monochrome (2017-11-22).
	* i8shark:  Adds CONFIG_IEEE802154_I8SHARK_XBEE_APPHDR option to remove
	  XBee's application header before sending to Wireshark. This option will
	  corrupt any traffic received that does not include this application
	  header.  From Anthony Merlino (2017-11-22).
	* apps/wireless/ieee802154/i8sak: Adds ability to get/set rxonidle
	  setting for MAC layer.  From Anthony Merlino (2017-11-xx).
	* apps/examples/fb:  Fix calculation of a mask value (2017-11-22).
	* NxWidgets:  Move from apps/NxWidgts to apps/graphics/NxWidgets
	  (2017-11-24).
	* apps/examples/pdcurses:  Add a very simple example that just shows the
	  entire character set (7-bit only).  It adapts to the size of the
	  framebuffer and, hence, can be used with very tiny displays.  In fact it
	  looks really dumb on big displays (2017-11-24).
	* apps/examples/fb:  Add a small delay between updating each rectangular
	  region (2017-11-25).
	* apps/examples: CONFIG_QENCODER was renamed to CONFIG_SENSORS_QENCODER:
	  update README.txt.  From Fabio D'Urso (2017-11-25).
	* apps/graphics/pdcurs34: Initial steps to support less than 8-pixel
	  fonts on less than 8-bit display.  Calculation of font buffer stride
	  must depend on the configured BPP.  Add first cut at function to copy a
	  font into the font buffer; Make better use of macros to reduce code
	  complexity (2017-11-27).
	* apps/examples/nunchuck: Add Nunchuck example application.  From Alan
	  Carvalho de Assis (2017-11-28).
	* apps/graphics/pdcurs34:  Correct logic that sets the font buffer to
	  the background color for the case of BPP < 8 (2017-11-29).
	* apps/examples/pdcurses:  Clean up charset example so that the display
	  geomtry  is better on very wide displays (wide with respect to the width
	  of a character) (2017-11-30).

	  graphics hardware if needed.  From Gregory Nutt (2018-01-18).
	* apps/netutils/netlib: Add default route in netlib_set_dripv4addr().
	  From Masayuki Ishikawa (2018-01-19).
	* system/stackmonitor:  Re-design the stack monitor so that it does not
	  make forbidden calls directly into the OS, breaking the portable POSIX
	  OS interface.  It now properly uses the PROCFS file system to glean
	  information about stack usage.  From Gregory Nutt (2018-01-20).
	* apps/nshlib:  Fix compile error when CONFIG_NSH_DISABLESCRIPT is not
	  defined.  The field np_flags does not exist if scripting is disabled.
	  From Gregory Nutt (2018-01-22).

	  Consists of some dispaly list helpers, audio helpers, touch helpers, RAM
	  access, register access etc.  From Gregory Nutt (2018-02-18).
	* apps/examples/ft80x:  Add a test of the FT80x based on FTDI
	  SampleApp.  Includes tests of GPU primitives and graphics co-processor
	  commands From Gregory Nutt (2018-02-18).

	  operations.  From Gregory Nutt (2018-02-19).
	* Added ECANCELED condition to DEBUGASSERT-s checking sem_wait result.
	  From Dmitriy Linikov (2018-02-20).
