   <a href="http://sourceforge.net/project/showfiles.php?group_id=189573">SourceForge</a> website.

 </p>
 <p>
-  This release includes one new, important extension to the
-  <a href="http://www.nuttx.org/NXGraphicsSubsystem.html">NX graphics system</a>:
+  This relese includes one new port, some new drivers and some important bugfixes:
   <ul>
-    <p>
-      NX was develop a couple years back on hardware that supported only framebuffer
-      devices, that is, video hardware with video memory directly converts the memroy
-      content to video.  However, most MCUs that NuttX focuses on do not support such
-      video memory; rather, that typically only support LCDs via parallel or serial
-      interfaces.
-    </p>
-    <p>
-      This release of NuttX extends NX so that now renders directly to the LCD device
-      via its serial or parallel interface.  No in-memory copy of the screen memory
-      need be maintained so this solution should also work in MCUs with very limited
-      SRAM.
-    </p>
+    <li><p>
+      NuttX was ported to the Luminary/TI LM3S6965 Ethernet Evaluation Kit.
+      At present, that port includes an OS test configuration and a NuttShell
+      (NSH) configuration with telnet support.
+    </p>
+    <p>
+      MMC/SD and Networking support are provided but not thoroughly verified
+      in this release: Current development efforts are focused on porting the
+      NuttX window system (NX) to work with the Evaluation Kits OLED display.
+    </p></li>
+    <li><p>
+      A NuttX Ethernet driver for the Microchip ENC28J60 SPI Ethernet chip is
+      available in the source tree (but has not yet been fully verified because
+      I haven't properly connected it to hardware yet).
+    </p></li>
+    <li><p>
+      The Olimex STR-P711 NuttX port was extended to support the ENC28J60 and
+      some new networking configurations were added.  The ENC28J60 has not
+      been tested on the STR-P711, however, because of hardware issues (I don't
+      think the USB powered board provides enough power for the ENC28J60 and
+      I don't have the right wall wart yet).
+    </p></li>
+    <li><p>
+      Along the way, external interrupt support (XTI) was added to the STMicro
+      STR-P711 port and some important bugs were fixed in the STR-P711 SPI
+      driver.
+    </p></li>
+    <li><p>
+      Corrected an important UDP reference counting error.  It was not a serious
+      error, but it trigger an assertion was IS a serious error.
+    </p></li>
   </ul>
 </p>
-<p>
-  This initial release of this feature includes the verified NX extensions plus
-  a driver for the HX8347, 16-bit parallel LCD.  This LCD supports 16-bit RGB
-  (5:6:5).

+          Features are the same as with the Eagle-100 LM3S6918 described above.
