+nuttx-5.14
+^^^^^^^^^^
+
+The 61st release of NuttX, nuttx-5.14, was mad on November 27, 2010.  This
+release includes multiple, important bugfixes as well as a new driver for
+the NXP LPC1766.
+
+Important bugfixes include:
+
+	* Cortex-M3 Hard Fault.  Fixed a hard fault problem that can occur if certain
+	  types 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.
+
+	* TCP/IP Sequence Number Bug.  Corrected errors some important logic in the way
+	  that sequence numbers are managed when send() sends out packets before a
+	  previous packet has been acknowledged.  Some of that send() logic was incompatible
+	  with logic in 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) send() might hang
+	  with outstanding, unacknowledged data (and with no re-transmission requests).
+	  This was due to differences in sequence number handling in send() and in
+	  uip_tcpinput.c; uip_tcpinput.c thought (incorrectly) that all of the bytes
+	  were acknowledged; send.c 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.
+
+Additional support has been included for the Olimex-LPC1766.  Support for that board
+was added to NuttX 5.13.  This release extends that support with an Ethernet driver.
+Verified configurations are now available for the NuttX OS test, for the NuttShell
+(NSH, see the <a href="ttp://www.nuttx.org/NuttShell.html">NSH User Guide</a>),
+for the NuttX network test, and for the THTTPD webserver. (Additional USB
+configurations are in the release as well, but those have not yet been verified. 
+Goals for NuttX-5.15 (and beyond) include: (1) Verified USB support, (2) SD card
+support, and (3) LCD support.
