nuttx-0.3.10 is an important bug fix release.
This release incorporates fixes to correct critical list handling errors
in task shutdown logic: One in timer deletion logic (timer_delete.c) and one
in stream logic (lib_init.c).
nuttx-0.3.11 is another important bugfix release.
This release fixes several bugs:
</p>
<ul>
<li>Two POSIX timer bugs: a memory leak as well a fatal sequencing error.</li>
<li>Several FAT filesystem errors.</li>
<li>A deadlock that can occur in <code>opendir()</code></li>
</ul>
<p>
Additional, minor enhancements includes support to ZiLOG EZ80Acclaim
microcontrooler (EZ80F91 chip) and configurations fot the ZiLOG z8f64200100kit (Z8F6423)
and ez80f0910200kitg (EZ80F091) development kit.
A few new features were also added:
</p>
<ul>
<li>Support for recursive mutexes</li>
<li>Added a RAM disk block driver</li>
<li>The host simulator no longer uses direct Linux system calls and now also works on Cygwin.</li>
<li>The OS test was strengthen and now runs as an endurance test</li>
</ul>
<p>
As usual, any feedback about bugs or suggestions for improvement would be greatly appreciated.
