   This release includes multiple, important bugfixes as well as a new driver for the NXP LPC1766.
   Important bugfixes include:
   <ul>
-	<li>
-	  Cortex-M3 Hard Fault.
-	  Fixed a hard fault problem that can occur if certaintypes of interrupts are pending at the time another interrupt returns.
-	  This problem has only been observed on the LPC1766 (returning from a SYSTICK interrupt with a pending Ethernet interrupt).
-	  However, it is assumed that all Cortex-M3 ports could have this as a latent bug.

     </li>
-	<li>
-	  TCP/IP Sequence Number Bug.
-	  Corrected errors some important logic in the way that sequence numbers are managed when <code>send()</code> sends out packets before a previous packet has been acknowledged.
-	  Some of that send() logic was incompatible with logicin the uIP layer.
-	  Errors seen include:
-	  (1) The final final packet in a sequence of packets might be too large!
-	  In the THTTPD example, this might leave some garbage at the bottom of the display.
-	  Or (2) <code>send()</code> might hang with outstanding, unacknowledged data (and with no re-transmission requests).
-	  This was due to differences in sequence number handling in <code>send()</code> and in <code>uip_tcpinput.c</code>;
-	  <code>uip_tcpinput.c</code> thought (incorrectly) that all of the bytes were acknowledged;
-	  <code>send.c</code> knew that they were not.

+      One-Shot POSIX Timer Bug.
+      Fixed an error in set-up of a one-shot POSIX timer.
+      It was using the repititive timer value (which is zero in the one-shot case), always resulting in a 10Ms timer!
+      Found and fixed by Wilton Tong.
