The 19th release of NuttX (nuttx-0.3.7) is available for download
The 20th release of NuttX (nuttx-0.3.8) is available for download
from the <a href="http://sourceforge.net/project/showfiles.php?group_id=189573">SourceForge</a>
website.

</p>
<p>
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.
</p>
<p>
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 <a href="TODO.txt">here</a>
The overall quality of NuttX (excluding the z16f port) continues to improve beyond the late beta level.
</p>
<p>
The z16f port required numerous changes to NuttX to handle:
</p>
<ul>
<li>NEAR and FAR addressing, and</li>
<li>Use of a Windows native toolchain in a Cygwin build environment.</li>
</ul>
<p>
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.
nuttx-0.3.8 is a minor bugfix release. It corrects a few minor problems, adds a few minor features, and
continues the integration of the ZiLOG Z18F and of the Pascal P-Code add-on.
This release is synchronized with the release of Pascal-0.1.2.
</p>
<p>
This release were verified on the ZiLOG z16f2800100zcog, Neuros OSD (ARM9), and the simulation platforms.
