+  This release adds graphics support and a tiny windowing subsystem.
-  This release includes the following new feature:
+  That new graphics subystem is documented in a <a href="NXGraphicsSubsystem.html">user manual</a>.
-<p>
+  No other substantial changes were made.
-<ul>
-  <li>Add <code>poll()</code> and <code>select()</code> APIs that may be used to monitor for data
-    availability on character devices or TCP/IP sockets.
-  </li>
-  <li>Implemented support TCP/IP connection backlog.
-   This allows <code>poll()</code>/<code>select()</code> to wake-up on new connections to a listener socket.
-  </li>
-  <li>Added definition of a framebuffer driver and implement framebuffer drivers for the
-    simulated platform and the TI DM320 (untested as of the initial check-in).
-  </li>
-  <li>Partially developed a graphics framework based on the framebuffer drivers, however,
-    this will not be ready for use for a few more release. 
-    Currently this includes only a few color conversion routines and some rasterizing functions.
-    A tiny windowing system is under development but not ready for check-in yet.
-  <li>Added support for fixed precision math.
-  </li>
-  <li>Added support for outgoing multicast packets.
-  </li>
-</ul>
-<p>
-  Several bugs were fixed, the most important of which are:
 </p>
-  <li>Fixed an important bug in the TCP/IP buffering logic.
-    When TCP/IP read-ahead is enabled and not recv() is in-place when a TCP/IP packet is received,
-    the packet is placed into a read-ahead buffer.
-    However, the old contents of the read-ahead buffer were not being cleared and old data would 
-    contaminate the newly received buffer.
-  </li>
-  <li>Changed the behavior of the serial driver read.
-    It now returns data as it is available rather than waiting for the full requested read size.
-    This makes functions like <code>fgetc()</code> work much more smoothly.
-  </li>
 <p>
-  These changes were verified only on the Neuros OSD (ARM) and the Linux simulator using a
+  The version number was bumped up to 0.4.0 in part to reflect the new graphics subsystem,
-  Linux development environment.
+  but also to recognize the NuttX is approaching complete functionality.  In the 0.3.x
+  versions, network support was added, Pascal P-code runtime support was added, FAT and
+  ROMFS filesystems were added, MMC/SD and USB device support were added.  There were
+  also numerous extensions to the NuttShell, NuttX APIs, and architecture ports.
