+nuttx-0.3.13
+^^^^^^^^^^^^
+
+This is the 25th release of NuttX.  This release includes some important bugfixes as well
+as a few new features.  Bugs fixed include:
+
+* Fixed problems with Cygwin-based console input.  NSH now works with the Cygwin simulator.
+* sched_get_priority_max/min returned error on SCHED_RR
+* Corrected detection of End-of-File in fgets()
+* Fixed an error in opendir() that could cause an assertion to fail inappropriately.
+* Corrected an error in the FAT that caused files opened for writing with O_APPEND to fail.
+* Fix error in getopt() when called with argc==1
+* Fix error in stat() when used on the root directory
+* Fixed a critical bug that effects the way that environment variables are shared amongst
+  pthreads.
+* uIP port now supports multi-threaded, concurrent socket access.  So, for example, one
+  thread can be reading from a socket while another is writing to the socket.
+
+New features were also added:
+
+* New OS APIs: chdir() and getcwd()
+* The Nuttx shell (NSH) has been extended in many ways.
+  - New commands: mkfatfs, mkfifo, sleep, usleep, nice, sh, cd, and pwd commands
+  - New memory inspection commands and heap usage commands
+  - New capabilities: Execution of commands in background, execution of simple scripts,
+    redirection of command output, last command status ($?)
+  - Now supports if-then[-else]-fi construct
+  - and other features as noted in the ChangeLog.
+
+These changes were verified only on the Host simulator under Cygwin and under Linux and
+also on the Neuros OSD (ARM9).  Please report any errors to me.
