+nuttx-0.3.0
+^^^^^^^^^^^
+
+This is the 12th release of NuttX.  This release includes the initial
+integration of a network subsystem and the uIP TCP/IP stack into NuttX
+(see http://www.sics.se/~adam/uip/index.php/Main_Page).  Also included
+is a device driver for the Davicom DM90x0 ethernet controller.
+
+This integration is very preliminary.  Only a small portion of the
+network functionality has been integrated and there are a number of
+open issues (see the TODO file).  The network subsystem is pre-alpha
+at this point in time.  I expect that it will stabilize and mature
+over the next few releases.
+
+The baseline functionality of NuttX continues to mature and remains at
+post-beta (as long as the network is not used).
+
+See the ChangeLog for a complete list of changes.
+
+This release has been verified only on the Neuros OSD (DM320 ARM9)
+platform using the DM90x0 driver.
+
+This tarball contains a complete CVS snapshot from November 6, 2007.
+
+nuttx-0.3.1
+^^^^^^^^^^^
+
+This is the 13th release of NuttX and the second release containing
+the integration of a network subsystem and the uIP TCP/IP, UDP, and
+ICMP stacks into NuttX (see http://www.sics.se/~adam/uip/index.php/Main_Page).
+
+Many network-related problems have been fixed and the implementation
+has matured significantly.  However, the level of network reliability
+is probably still at the pre-alpha or early level.  It is sufficiently
+complete that you may begin to perform some network integration and
+is exepcted to achieve beta level of reliability over the next few
+releases.
+
+The baseline functionality of NuttX continues to mature and remains at
+post-beta (as long as the network is not used).
+
+See the ChangeLog for a complete list of changes.
+
+This release has been verified only on the Neuros OSD (DM320 ARM9)
+platform using the DM90x0 driver.

+
+nuttx-0.3.2
+^^^^^^^^^^^
+
+This is the 14th release of NuttX and the 3rd release containing
+the integration of a network subsystem and the uIP TCP/IP, UDP, and
+ICMP stacks into NuttX (see http://www.sics.se/~adam/uip/index.php/Main_Page).
+
+Many network-related problems have been fixed and the implementation
+has matured significantly.  This release consists of:
+
+o TCP-related bug-fixes
+o TCP performance improvements
+o Initial UDP integration
+o Initial uIP micro webserver integration
+
+See the ChangeLog for a complete list of changes.
+
+The level of network reliability is at alpha level is expected to
+achieve beta level of reliability over the next few releases.
+
+The baseline functionality of NuttX continues to mature and remains at
+post-beta.
+
+This release has been verified only on the Neuros OSD (DM320 ARM9)
+platform using the DM90x0 driver.
+
+This tarball contains a complete CVS snapshot from November 23, 2007.
+
+nuttx-0.3.3
+^^^^^^^^^^^
+
+This is the 15th release of NuttX and the 4th release containing
+the integration of a network subsystem and the uIP TCP/IP, UDP, and
+ICMP stacks into NuttX (see http://www.sics.se/~adam/uip/index.php/Main_Page).
+
+Many network-related problems have been fixed and the implementation
+has matured significantly.  This release consists of:
+
+o TCP-related bug-fixes for disconnecting sockets
+o Correction of some TCP read-ahead logic
+o TCP performance improvements
+o Misc. additions and cleanup (See the ChangeLog for a complete list of
+  changes).
+
+The level of network reliability is at an early beta release level.  The
+baseline functionality of NuttX continues to mature and remains at
+post-beta. Open network-related issues include only:
+
+o Some minor unimplemented BSD socket functionality,
+o Thread safety issues: the same socket cannot be used concurrently on
+  different threads.
+o Pending design changes necessary to support multiple network interfaces.
+o IPv6 support is incomplete.
+
+This release has been verified only on the Neuros OSD (DM320 ARM9)
+platform using the DM90x0 driver. Any feedback for improving the network
+reliability/performance would be greatly appreciated.

+
+nuttx-0.3.4
+^^^^^^^^^^^
+
+This is the 16th release of NuttX and the 5th release containing
+the integration of a network subsystem and the uIP TCP/IP, UDP, and
+ICMP stacks into NuttX (see http://www.sics.se/~adam/uip/index.php/Main_Page).
+
+This release is primarily a bug-fix release.  New features include
+only:
+
+o TELNET front-end to NSH,
+o DHCPC server functionality, and
+o C5471 Ethernet driver.
+
+Numerous network related problems were fixed related to DHCPC, UDP
+input processing, UDP broadcast, send timeouts, and bad compilation when
+uIP is compiled at high levels of optimization.
+
+The level of network reliability is at a strong beta release level.  The
+baseline functionality of NuttX continues to mature and remains at
+post-beta or production level.
+
+Parts of this release were verified only on the Neuros OSD (DM320 ARM9)
+platform using the DM90x0 Ethernet driver and other parts on the Spectrum
+Digital C5471 EVM using the C5471 Ethernet driver. Any feedback about bugs
+or suggestions for improving the network reliability/performance would be
+greatly appreciated.

+^^^^^^^^^^^
+
+This is the 17th release of NuttX this release is primarily a bug-fix
+release and intended to synchronize with the current CVS contents.  See
+the ChangeLog for a detailed list of changes and fixes.
+
+This release were verified only on the Spectrum Digital C5471 EVM using
+the C5471 Ethernet driver. Any feedback about bugs or suggestions for
+improvement would be greatly appreciated.

+
+nuttx-0.3.6
+^^^^^^^^^^^
+
+This is the 18th release of NuttX.  This release contains on a few
+changes.  The primary purpose of this release is to synchronize with
+the release of the pascal-0.1.0 add-on package.
+
+This release of NuttX includes the following changes:
+
+* Fixes for use with SDCC compiler
+* Added a simulated z80 target (arch/z80)
+* Fix deadlock errors when using stdio but with no buffering
+* Add support for the add-on Pascal P-Code interpreter (pcode/)
+  (see the pascal-0.1.0 package)
+
+This release were verified only on the simulated Z80 and and host
+simulation targets.  As usual, any feedback about bugs or suggestions
+for improvement would be greatly appreciated.
+
+This tarball contains a complete CVS snapshot from January 6, 2007.
+
+====
+
+There was an error in the initial 0.3.6 release that prevented
+a successful build unless the Pascal add-on was present.  The
+tarball was patched to include the fix.  Make sure that you download
+the nuttx-0.3.6.1.tar.gz version to avoid this problem.
+
+nuttx-0.3.7
+^^^^^^^^^^^
+
+This is the 19th release of NuttX.  This release includes the
+preliminary port of NuttX to the ZiLOG z16f 16-bit microcontroller.
+This port was verified using the ZiLOG z16f2800100zcog Development
+and the ZiLOG ZDS-II toolchain. See http://www.zilog.com for
+further information.
+
+I emphasize that this is a preliminary release of the z16f port and
+is only alpha or, perhaps, pre-alpha quality as of this writing.
+There are a list of known issues in the TODO file in the root of
+the NuttX directory.  The overall quality of NuttX (excluding the
+z16f port) continues to improve beyond the late beta level.
+
+The z16f port required numerous changes to NuttX to handle:
+
+* NEAR and FAR addressing, and
+* Use of a Windows native toolchain in a Cygwin build environment.
+
+In addition to the z16f port, at least one very critical bug was
+found and corrected in NuttX:  The thread-specific errno value of one
+task was being randomly trashed when a different thread exitted.
+
+This release were verified on the ZiLOG z16f2800100zcog, Neuros OSD
+(ARM9), and the simulation platforms.  As usual, any feedback about bugs
+or suggestions for improvement would be greatly appreciated.
