-  This release completes the verification of the basic port for the NXP
-  <a href="http://ics.nxp.com/products/lpc3000/lpc313x.lpc314x.lpc315x/">LPC3131</a> MCU
-  on the <a href="http://www.embeddedartists.com/products/kits/lpc3131_kit.php">Embedded Artists EA3131</a> board.
-  This basic port includes basic boot-up, serial console, and timer interrupts.  This port
-  has been verified on the using the NuttX OS test and includes a working
-  implementation of the NuttShell (NSH).
+  This release suport for one new achitecture:
 </p>
+<ul>
+  <li>A basic port for the NXP LPC2378 MCU on the Olimex-LPC2378 development board was contributed by Rommel Marcelo.</li>
+</ul>
 <p>
-  An extended release will follow and should include SDIO-based SD card
-  support and device USB.
+ And extensions to two existing architures:
 </p>
+<ul>
+  <li>David Hewson contributed a dual-speed (full/high) USB device-side driver
+    for the NXP LPC3131 on the Embedded Artists EA3131 development board.</li>
+  <li>A DMA driver and a high speed MCI driver for the Atmel AT91SAM3U are
+    included (but not fully tested in this release).</li>

-  A few additional features and bugfixes of a minor nature were also incorporated
-  as detailed in the <a href="#currentrelease">ChangeLog</a>.
+  Two important bugfix was also included:
 </p>
+<ul>
+  <li>An important fix to the USB mass storage driver was contributed by David Hewson.</li>
+  <li>A serious error in the AT91SAM3U PIO handling was fixed.</li>

-	* arch/arm/src/sam3u/sam3u_pio.c - Fix an address calculation error
-	  that caused ports B & C to get mapped to the PIOA base address.
-	  This is an important bugfix! (a patch is available)
-	* arch/arm/src/lpc313x/lpc313x_boot.c - Fix an error in the vector
-	  initialization was causing a memory fault.

-	* arch/arm/src/arm/up_head.S - Corrected backward conditional compilation
-	  that selects if vectors are located at 0x0000:0000 or 0xffff:f000.
-	  This fixes the last show stopper bug in the lpc313x bring-up.
-	* configs/ea3131/nsh - Added a NuttShell (NSH) configuration for the

+	  Basic port of the NXP 2378 on the Olimex board contributed by
+	  Rommel Marcelo.
+	* arch/arm/src/sam3u/sam3u_internal.h - Fixed a critical bug in the AT91SAM3U
+	  PIO decoding.  No PIOs greater than 15 could be used on any port!  Obviously,
+	  no one has been using this port.
