+nuttx-5.7
+^^^^^^^^^
 
+This is the 54th release of NuttX.  This release adds basic support for one new
+ARM Cortex-M3 architecture:
+
+  * Added support for NXP LPC1768 MCU as provided on the Nucleus 2G board from
+    2G Engineering (http://www.2g-eng.com).
+  * Some initial files for the LPC17xx family were released in NuttX 5.6, but the
+    first functional release for the NXP LPC1768/Nucleus2G occured with NuttX 5.7.
+  * That initial basic release included timer interrupts and a serial console and was
+    verified using the NuttX OS test.
+  * That release includes a verified NuttShell (NSH) configuration
+    (see the http://www.nuttx.org/NuttShell.html).
+  * Also included are unverified SPI and USB device drivers.
+
+Further efforts include: (1) development of a DMA support library, (2) SPI-based MMC/SD
+support, and (3) verification of the USB driver.  Watch for announcement of the completed
+LPC1768 port expected in NuttX-5.8.
