+  This release of NuttX incorporates the verified port of Jeff Poskanzer's <a href="http://acme.com/software/thttpd">THTTPD</a> HTTP server.
+  Many of the key features of THTTPD have been tested on the Micromint Eagle-100 development board (Cortex-M3).

+</p>
+<ul>
+  <li>Serving of files from any file system, and </li>
+  <li>Execution of CGI executable.
+    This release supports execution of <a href="http://www.nuttx.org/NuttXNxFlat.html">NXFLAT executables</a> residing on a ROMFS file system.
+</ul>
+<p>
+  A standard CGI interface is used:  Information is pasted to the CGI program via POST commands and via environment variables.
+  CGI socket I/O is redirected to <code>stdin</code> and <code>stdout</code> so that the CGI program only need to <code>printf()</code> to send its content back to the HTTP client.
 </p>
-  The changes in thsi release focus on the port of Jeff Poskanzer's
-  <a href="http://acme.com/software/thttpd/">THTTPD</a> to NuttX.
-  Do to limited time to work on NuttX, that port is still not fully functional.
-  However, numerous related bug-fixes and functional additions for THTTPD were
-  added:
-  <ul>
-    <li>Several new standard C-library functions (<code>fileno</code>, <code>strstr</code>,
-        <code>strpbrk</code>, <code>fcntl</code>).</li>
-    <li>Improved and extended timing APIs (<code>mktime</code>, <code>gmtime</code>, <code>gmtime_r</code>,
-        <code>gettimeofday</code>, <code>localtime</code>, <code>localtime_r</code>, and
-        <code>strftime</code>)</li>
-    <li>Networking enhancements: <code>recvfrom</code> and <code>accept</code> now work with non-blocking
-	sockets.</li>
-    <li><a href="NuttXNxFlat.html">NXFLAT</a> extensions (<code>exec</code>)</li>
-    <li>Pattern matching logic.</li>
-    <li>And miscellaneous bug fixes (see the <a href="#currentrelease">ChangeLog</a> for a complete list).</li>
-  </ul>
+<p>
+  Another value to this THTTPD integration effort has been that THTTPD has provided a very good test bed for finding NuttX networking bugs.
+  Several very critical networking bugs have been fixed with this 0.4.11 release (see the <a href="#currentrelease">ChangeLog</a> for details).
+  Networking throughput has also been greatly improved.
+  Anyone using NuttX networking should consider upgrading to this release.

-	* lib/: Added some basic regex-subset, pattern matching functions
-	* lib/: Greatly simplified mktime() and gmtime_r().  The Gregorian and
-	  Julian time calculations were interesting, but not necessary in the

-	* sched/: Added gettimeofday().  This implementation is simply a thin
-	  wrapper around clock_gettimer().
-	* lib/: Add gmtime(), localtime(), and strftime()
-	* binfmt/: Add exec().  This is just a wrapper that executes both
-	  load_ and exec_module() in a more familiar manner.  It is not consistent
-	  with more standard exec() functions, however, because (1) it returns
-	  and (2) it requires symbol table arguments.
-	* lib/: Add fileno()
-	* examples/ostest: Several of the tests used a big, hard-coded stack size
-	  when creating test threads (16Kb stacksize).  The stack size should
-	  be controlled by the .config file or the OSTest won't work on platforms
-	  with memory constraints.
-	* netutils/thttpd: An initial port of Jef Poskanzer's THTTPD HTTP server.

-	* configs/ntosd-dm320/thttpd: A build configuration for THTTPD on the Neuros
-	  DM320 platform.
-	* lib/: Added strstr() and strpbrk().
-	* net/recvfrom.c and net/accept(): Sockets now support some non-blocking
-	  operations, specifically for (1) TCP/IP read operations when read-ahead
-	  buffering is enabled, and (2) TCP/IP accept() operations when TCP/IP
-	  connection backlog is enabled.
-	* fs/fs_fcntl.c and net/net_vfcntl.c: Minimal support provided for fcntl().
-	  It can, at least, be used to mark sockets as blocking or non-blocking.
-	* net/net_close.c: Fix bug in close().  If reference count not set to zero
-	  then uip_tcpfree() will assert when DEBUG is enabled.
-	* net/accept.c: Fix bug in accept().  The logic expected parts of the
-	  return address structure to be initialized or it would return an error.
