-0.1.0 2007-03-09  Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
-
-	* Initial Release
-	* Support for Linux user mode simulation and TI
-	  TMS320C5471 (Arm7) provided
-
-0.1.1 2007-03-14  Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
-
-	* Corrected an error in interrupt level context switching
-	  for C5471
-	* Added fgets() and gets() logic; verified c5471 console read.
-	* Corrected error in reading from the C5471 serial port:
-          Improper use of semaphore can cause deadlock.
-	* Fixed an error in the memory cleanup:  The idle task
-	  cannot take sempahores (because it must always be ready
-	  to run).
-	* Tasks can now accept a configurable maximum number of
-	  input parameters (argc)
-	* _task_init() was divided into separate functions that
-	  require fewer parameters.  This was necessary to keep
-	  the stack usage down for the 8051/2 (which has only
-	  256 bytes of stack).
-	* Attempts to use C5471 console from interrupt handlers
-	  can cause errors. Added a special path for this case.
-	* Refuse calls to sem_wait and sem_trywait from interrupt
-	  handlers.  This was happening because interrupt handlers
-	  were calling printf-like functions.
-	* Added strtok() and strtok_r()
-	* Added a simple shell called nsh (see examples/nsh).
-	* Platform support for 8052 is complete but not stable
-	  when the timer interrupt is enabled.  Seems to be an
-	  issue when SP enters indirect address space.
-	* Documentation updates
-
-0.1.2 2007-03-19  Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
-
-	* Add dirent.h, opendir(), readdir(), closedir(), etc.
-	* Add strerror()
-	* Added 'ls' command to nsh
-	* Added C5471 watchdog driver
-	* Fixed another bug where free() is called from IDLE task.
-	  Can't do this; the caller must be able to wait for access
-	  to memory.
-	* Fixed bugs associated with debug output:
-          Cannot do dbg() in middle of context switch logic.
-	  because it may require use of semaphores and cause
-	  additional context switches. lldbg() is safe.
-	* Interrupt must be disabled throughout all context switches.
-	* Separated C5471 serial driver; a shareable part is
-	  in drivers/. ; the C5471 specific part is in arch/C5471.
-	  serial.h defines the interface.
-	* Fixed mq_receive() and mq_send() -- bad memcpy()
-	* Fixed C5471 signal deliver logic: use of dbg() and
-          other actions by use signal handler can alter errno.
-          need to protect errno during signal handling.
-	* Fixed uninitialized variable in filesystem that could
-	  cause various problems
-	* Added a test for roundrobin scheduler.
-
-0.2.1 2007-03-22  Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
-
-	* Fix error in handing signed decimal in vsprintf().
-	* Major restructuring of header files to get closer to
-	  POSIX compliance.
-	* Eliminate compilation warnings that that crept into
-	  recent check-ins
-	* Add kill()
-	* Added support for POSIX timers
-	* Some Documentation updates
-	* Added support for the Neuros OSD / DM320
-
-0.2.2 2007-03-26 Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
-	* Created the configs/ directory; separated board configuration
-	  from processor architecture logic
-	* Add memory leak detection test to examples/ostest
-	* Corrected memory leak in OS pthread join logic
-	* Corrected memory leaks in examples/ostest due to failures
-	  to join or detach from pthreads.
-	* Added pthread_once(), pthread_kill(), pthread_sigmask()
-	* Added pthread_barrierattr_*() APIs
-	* Added pthread_barrier_init(), pthread_barrier_destroy(), and
-	  pthread_barrier_wait();
-	* Added pthread barrier test
-	* Added protection so that errno cannot be modified from
-	  interrupt handling.
-	* sched_setparam(), sched_setscheduler() now correctly set
-	  errno; pthread_setscheduler() now returns the correct errno.
-	* Added pthread_setschedprio().
-	* Added directories to hold board-specific header files
-	* Added directories to hold board-specific drivers
-
-0.2.3 2007-03-29 Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
-
-	* mq_receive and mq_send now return errno's appropriately
-	* mq_receive and mq_send are now correctly awakened by signals.
-	* Fixed an unmatched sched_lock/unlock pair in task_delete().
-	* sched_lock must be called in _exit() because operation of
-	  task_delete() can cause pending tasks to be merged and a
-	  context switch to occur.
-	* Added mq_timedreceive() and mq_timedsend()
-	* signal mask is now inherited by both child tasks and threads.
-	* Improved sharebility of stdout among pthreads (only).  Nothing
-	  was broken, but by moving the mutual exclusion logic to a
-	  higher level, the printf output is more readable.
-	* Fixed a bug in file system cleanup:  A list was being deleted
-	  before the buffers contained in the list.
-	* Fixed a bug in the wait-for-message-queue-not-empty logic.
-	* Added a test of timed mqueue operations; detected and corrected
-	  some mqueue errors.
-	* Identified and corrected a race condition associated with
-	  pthread_join.  In the failure condition, memory was being
-	  deallocated while still in use.
-
-0.2.4 2007-04-28 Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
-
-	* Verfied c5471 build under Cygwin on WinXP
-	* Makesystem changes to better support different SoCs.
-	* Made arch/c5471/include and arch/dm320/include identical in
-	  preparation for merging into arch/arm
-	* Logic from arch/c5471 and arch/dm320 combined into arch/arm.
-	  arch/c5471 and arch/dm320 are deprecated and will be removed
-	  when the new c5471 and dm320 logic is verified.
-
-0.2.5 2007-05-19 Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
-
-	* Corrected some build/configuration issues introduced with the
-	  last release.
-	* Added support for the NXP 214x processor on the mcu123.com lpc214x
-	  development board (untested)
-	* Added support for block devices.
-	* Simulated target now exports a VFAT filesystem
-	* Begin support for VFAT filesystem (missing functionalit)
-	* Added mount() and umount()
-	* Fix bug in memcmp return value
-	* Fix errors in timeslice calculation (several places)
-	* Added missing irqrestore() in timer_deletall().
-	* close() was not closing the underlying device.
-	* Added fsync()
-	* Added strspn() and strcspn()
-
-0.2.6 2007-05-26 Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
-
-	* Added unlink(), mkdir(), rmdir(), and rename()
-	* Fixed several serious FAT errors with oflags handling (&& instead of &)
-	* Added FAT support for unlink(), mkdir(), rmdir(), and rename
-	* Added FAT support for opendir(), closedir(), readdir(), seekdir(),
-	  telldir(), rewindir().
-	* Fixed ARM compilation errors introduced in 0.2.5 (that is what I get
-	  for only testing on the simulation).
-
-0.2.7 2007-06-09 Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
-
-	* Added stat() to fs layer and to FAT
-	* Fixed reference counting errors associated with mounted filesystems
-	* Added fat_getattrib() and fat_setattrib()
-	* Added statfs() to fs layer and to FAT
-	* Correct file name extension in tools/zipme.sh
-	* Fix error in dependencies in 8051/2 Makefile
-	* sched/Makefile: Don't build sleep() or usleep() if signals are disabled
-	* sched/sched_setparam.c: Remove redundant disabling of interrupts
-	* sched/usleep.c: Fixed nsec calculation
-	* lib/lib_strcspn.c: Function incorrectly named strspn().
-	* examples/ostest/main.c:  Errors in SDCC version of a memcpy() call
-	* examples/ostest/sighand.c: Don't call fflush() if streams are disabled
-	* include/limits.h, include/time.h, sched/clock_internal.h: A support for
-	  using selectable system timer frequency.
-	* Fixed error in mountpoint related conditional compilation introduced
-	  in 0.2.5
-	* Restructured some Makefiles to better handle enabling and disabling
-	  NuttX features without having so much conditional compilation in the
-	  source files.
-	* tools/mkconfig.c: No longer depends on asprintf() and _GNU_SOURCE and
-	  so should now build in non-GNU, non-GLIBC environments.
-	* include/nuttx/compiler.h: Fix for using SDCC with the Z80.
-	* include/assert.h & arch/pjrc-8051/src/up_assert.c: SDCC does support
-	  __FILE__and __LINE__ (not tested)
-	* examples/ostest/barrier.c: Don't call usleep() when signals are
-	  disabled.
-
-0.2.8 2007-07-02 Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
-	* tools/Makefile.mkconfig: Under Cygwin, executable has a different name
-	* tools/mkdeps.sh & arch/arm/src/Makefile: Corrected a problem makeing dependencies
-	* tools/zipme.sh: Force directory name to be nuttx-xx.yy.zz
-	* fs/fs_opendir.c: Correct errors in semaphore usage that can cause deadlock.
-	* lib/lib_getopt.c: Added getopt() support
-	* examples/nsh/:  NSH now supports cat, mount, umount, and mkdir.  ls supports
-	  -l -s, and -R
-	* Added basic OS support to manage environment variables:  environment
-	  storage, cloning on task creation, sharing on pthread creation, destruction
-	  on thread/task exit.
-	* Add environment variables APIs:  environ, getenv, putenv, clearenv, setenv,
-	  unsetenv
-	* Correct an error in realloc() when the block is extended "down" in memory.
-	  In this case, the old memory contents need to be copied to the new location
-	  and an allocated bit was not being set.
-	* examples/ostest/: Added an environment variable test.
-	* examples/nsh/: Break into several files.
-	* lib/: Added strrchr, basename, dirname
-	* examples/nsh/: Add cp, rm, rmdir, set, unset commands. echo will now print
-	  environment variables.
-
-0.3.0 2007-11-06 Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
-
-	* Imported uIP into the tree (see
-	   http://www.sics.se/~adam/uip/index.php/Main_Page)
-	* Adding socket(), bind(), connect()
-	* Added snprintf()

-
-0.3.1 2007-11-19 Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
-
-	* Separated net/uip/uip.c into several functions in several files.
-	* Corrected a TCP problem where packets were dropped because there was no
-	  recv() in place but the packet was being ACKed.  There are still TCP
-	  recv buffering issues, but this is part of a larger buffering issue.
-	* Basic server functionality verified: listen(), accept()
-	* Fix DM90x0 driver problem that caused TX overruns
-	* Add strncmp()
-	* Added TCP/IP read-ahead buffer to minimize failed ACKs and packet loss.
-
-0.3.2 2007-11-23 Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
-
-	* Add strcat() and strncat()

-	  the availability of TX data.
-	* Moved urgent data info into device structure.
-	* TCP and ICMP protocols can now be disabled.
-	* Added UDP test in examples/udp
-	* Verified/debugged UDP socket(), bind(), sendto() and recvfrom() logic
-	  using examples/udp
-	* recvfrom() and accept() now correctly return the remote address.
-	* Fixed computation error in ntohl().
-
-0.3.3 2007-11-28 Gregory Nutt <spudmonkey@racsa.co.cr>
-
-	* Removed unused uIP files
-	* sched/, mm/, and net/ subystem debug can not be selectively enabled/disabled
-	* Correct socket close logic -- needs to disconnect TCP socket on close
-	* uIP webserver now seems to be fully functional
-	* fs/ and lib/ subystem debug can not be selectively enabled/disabled
-	* Added vsnprintf
-	* Integrated uIP telnetd
-	* Add missing logic to readahead buffer logic
-	* examples/nettest uses larger buffers
-	* Improved ACK handling in send() to better hander deferred acknowledgements
-	  and polling intervals.  Greatly improves send performance.

-NuttX TODO List
-^^^^^^^^^^^^^^^
-
-o Task/Scheduler
-- When a tasks exits, shouldn't all of its child pthreads also be terminated?
-- Should task_delete() cause atexit() function to be called?
-- Implement sys/mman.h and functions
-- Implement sys/wait.h and functions
-- Implement priority inheritance
-- Consider implementing wait, waitpid, waitid.  At present, a parent has
-  no information about child tasks.
-- Several APIs do not set errno.  Need to review all APIs.
-
-o Memory Managment
-- Add an option to free all memory allocated by a task when the task exits.
-  This is probably not be worth the overhead for a deeply embedded system.
-- Current logic adapts size_t for 16-bit address machines vs. 32-bit address
-  machines.  But a small memory option should also be provided so that
-  the small offset option can be used with 32-bit machines that have small
-  RAM memories (like the lpc2148)
-
-o Signals
-- 'Standard' signals and signal actions are not supported.
-
-o pthreads
-- pthread_cancel():  Should implement cancellation points and pthread_testcancel()

+
+
+o Task/Scheduler (sched/)
+  ^^^^^^^^^^^^^^^^^^^^^^^
+
+  Description: When a tasks exits, shouldn't all of its child pthreads also be
+               terminated?
+  Status:      Open
+  Priority:    Medium, required for good emulation of process/pthread model.
+
+  Description: atexit() supports registration of one function called on exit().
+               Should task_delete() also cause atexit() function to be called?
+  Status:      Open
+  Priority:    Low, task_delete() is non-standard and its behavior is
+               unspecified.
+
+  Description: Implement sys/mman.h and functions
+  Status:      Open
+  Priority:    Low
+
+  Description: Implement sys/wait.h and functions.  Consider implementing wait,
+               waitpid, waitid.  At present, a parent has no information about
+               child tasks.
+  Status:      Open
+  Priority:    Low
+
+  Description: Implement priority inheritance
+  Status:      Open
+  Priority:    Medium, this is a good feature for realtime systems.
+
+  Description: Several APIs do not set errno.  Need to review all APIs.
+  Status:      Open
+  Priority:    Medium, required for standard compliance (but makes the
+               code bigger)
+
+o Memory Managment (mm/)
+  ^^^^^^^^^^^^^^^^^^^^^^
+
+  Description: Add an option to free all memory allocated by a task when the
+               task exits. This is probably not be worth the overhead for a
+               deeply embedded system.
+  Status:      Open
+  Priority:    Medium/Low, a good feature to prevent memory leaks but would
+               have negative impact on memory usage and code size.
+
+  Description: Current logic adapts size_t for 16-bit address machines vs.
+               32-bit address machines.  But a small memory option should also
+               be provided so that the small offset option can be used with
+               32-bit machines that have small RAM memories (like the lpc2148)
+  Status:      Open
+  Priority:    High, a good feature enhancement.
+
+o Signals (sched/, arch/)
+  ^^^^^^^^^^^^^^^^^^^^^^^
+
+  Description: 'Standard' signals and signal actions are not supported.
+               (e.g., SIGINT, SIGCHLD, SIGSEGV, etc).
+  Status:      Open
+  Priority:    Low, required by standards but not so critical for an
+               embedded system.
+
+o pthreads (sched/)
+  ^^^^^^^^^^^^^^^^^
+
+  Description: pthread_cancel():  Should implement cancellation points and
+               pthread_testcancel()
+  Status:      Open
+  Priority:    Low, probably not that useful
 
 o C++ Support
-- Need to call static constructors
-
-o Network
-- uIP's netutils/smtp, resolv, webclient -- untested
-- Should implement SOCK_RAW, SOCK_PACKET
-- uIP polling issues:
-  (1) Current logic will not support multiple ethernet drivers.  Each driver should
-      poll on TCP connections connect on the network supported by the driver; UDP
-      polling should respond with TX data only if the UDP packet is intended for the
-      the network supported by the driver.
-  (2) If there were multiple drivers, polling would occur at double the rate.i
-  Fix by using bound IP address in TCP connection (lipaddr) and verifying that it
-  is in the subnet served by the driver.
-- uIP/Socket callback logic is not thread safe. This means that a socket cannot be
-  used concurrently by two threads.  Minimal fix:  Add mutex to support exclusion.
-- IPv6 support is incomplete
-- Incoming UDP broadcast should only be accepted if listening on INADDR_ANY(?)
-- Should add some driver call to support throttling... when there is no listener
-  for new data, the driver should be throttled.  Perhaps the driver should disable
-  RX interrupts when throttled and re-anable on each poll time.  recvfrom would,
-  of course, have to un-throttle.
-- Need to standardize collection of statistics from network drivers.  examples/nsh
-  ifconfig command should present statistics.
-
-o USB
-- Implement USB device support
-- Implement USB bulk device
-
-o Libraries
-- sscanf() and lib_vsprintf() do not support floating point values.
-- The definition of environ in stdlib.h is bogus and will not work as it should.  This
-  is because the underlying representation of the environment is not an arry of pointers.
-
-o File system
-- Add chmod(), truncate().
-- FAT32: long file names
-
-o Documentation
-- Document driver/ logic
-- Document C-library APIs
+  ^^^^^^^^^^^
+
+  Description: Need to call static constructors
+  Status:      Open
+  Priority:    Low, depends on toolchain.  Call to gcc's built-in static
+               constructor logic will probably have to be performed by
+               user logic in user_start().
+
+o Network (net/, netutils/)
+  ^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  Description: Several of the netutils/ apps are untested.  These include
+               uIP's netutils/smtp, dhcpd, resolv, webclient.  Only minimal
+               testing of the others has been performed.
+  Status:      Open
+  Priority:    Medium, Important but not core NuttX functionality
+
+  Description: Should implement SOCK_RAW, SOCK_PACKET
+  Status:      Open
+  Priority:    Low
+
+  Description: uIP polling issues / Multiple network interface support:
+               (1) Current logic will not support multiple ethernet drivers.
+                  Each driver should poll on TCP connections connect on the
+                  network supported by the driver; UDP polling should respond
+                  with TX data only if the UDP packet is intended for the
+                  the network supported by the driver.
+               (2) If there were multiple drivers, polling would occur at
+                  double the rate.  Fix by using bound IP address in TCP
+                  connection (lipaddr) and verifying that it is in the subnet
+                  served by the driver.
+  Status:      Open
+  Priority:    Medium, The feature is not important, but it is important
+               for NuttX to resolve the architectural issues.
+
+  Description: Sendoto() and multiple network interface support:

+  Description: uIP/Socket callback logic is not thread safe. This means that
+               a socket cannot be used concurrently by two threads.  Minimal
+               fix:  Add mutex to support exclusion for protection.

+               by threads with out a major redesign.  The feature is not
+               of great value since the use model for multi-thread sockets
+               is not common.  Adding mutex support would only mask the

+               driver should be throttled.  Perhaps the driver should disable
+               RX interrupts when throttled and re-anable on each poll time.

-o ARM/DM320
-- It seems that when a lot of debug statements are added, the system no
-  longer boots.  This has been diagnosed as a stack problem.. making the stack

-- Finish bringup
-- Add MMC and USB support
-
-o pjrc-8052 / MCS51
-- Current status:
-  - Basic OS task management seems OK
-  - Fails when interrupts enabled.  The stack pointer is around 0x6e
-    before the failure occurs.  It looks like some issue when the
-    stack pointer moves from the directly to indirectly addressable
-    region (0x80 boundary).
-  - Work on the 8052 is temporarily on hold
-- Use timer 0 as system timer.  Timer 2 is needed for second UART.
-  Logic is implemented, but there needs to be a system configuration
-  to change the ticks-per-second value to match the timer interrupt
