-  </li>
-  <li><b>STM32</b>.
-     The CAN driver has been verified in loopback mode.  ADC driver
-     support for the STM32 F4.  Add support for UART4-5 and USART6
-     (Contributed by Mike Smith).  The PWM driver now supports a pulse

-     timers (Contributed by Mikhail Bychek)
+  <li><b>Genernal Drivers</b>.
+    Added support for (29-bit) extended CAN IDs.
+    Added an infrastructure to support battery drivers.

+    Add support for Composite USB drivers (in particular for a CDC/ACM with MSC USB composite driver).
   </li>
-  <li><b>STM32F4Discovery</b>.
-     Support for the STM32F4-Discovery board contributed
-     by Mike Smith.

-  </li>
-  <li><b>LPC17xx</b>.
-     Add support for loopback mode to CAN driver.  CAN TX done 
-     perations are now interrupt driver.  Now supports configurable CAN bit
-     rate.
+  <p>
+    Added a new RAM logging driver.
+    This will allow debug output into a RAM buffer associated with a character driver at <code>/dev/syslog</code>.
+    Added the new command <code>dmesg</code> to NSH that can be used to dump the  current contents of the log.
+    This is useful for systems that do not have the usual serial console (for example, if you only have a Telnet console with NSH).
+  <li><b>Networking</b>.
+    Added a lower level, primitive socket interface.  Added a new Telnet driver:
   </li>
-  <li><b>LPC1766-STK</b>.
-     Add support for on-board buttons. Add support for user
-     control of LEDs.
+  <p>
+    A New Telnet daemon was created.
+    It wraps a Telnet session within a character driver that can serve as a &quot;controlling terminal.&quot;
+    The Telnet session will then be inherited by tasks created from the Telnet session and the <code>stdin</code>/<code>stdout</code> from the created task will still go through the same Telnet connection.
+  </p>
+  <li><b>STM32 Drivers</b>.
+    PWM driver pulse count was limited to 128; now is (essentially) unlimited.
+    Added support for (29-bit) extended CAN IDs.
+    Add support for I2C3.
+    The SDIO driver is (mostly) verified on the STM32 F4 platforms.

-     by Mike Smith)
+  <li><b>LPC17xx Drivers</b>.
+    Extended the CAN driver so that the TSEG1 and TSEG2 bit times can be set via the NuttX configuration.
+    Add support for (29-bit) extended CAN IDs.
   </li>
   <li><b>PIC32MX</b>.
-     USB device-side driver (needs further testing).  A partial
-     Ethernet driver is also in place.
+    The PIC32 Ethernet driver is code complete (but still untested).
+  </li>
+  <li><b>FTPD</b>.
+    Added a new FTP server daemon.
+    This is based loosely on the <i>hwport_ftpd</i> library provided by Jaehyuk Cho.
   </li>
   <li><b>Library</b>.
-     Support added for fixed floating point fieldwidths in output
-     formatting (Contributed by Mikhail Bychek)
+    Add support for <code>on_exit()</code>.
+    Implemented <code>tcsetattr()</code> and <code>tcgetattr()</code>.
+    Moved the old, too-smart <code>fgets()</code> to a new application library function called <code>readline()</code>.
+    Dumbed down the original <code>fgets()</code>.
+    Add <code>strcasestr()</code>, <code>avsprintf()</code>, <code>inet_ntop()</code>, and i<code>net_pton()</code>.
+    Add support to enable or disable debug output.
   </li>
-  <li><b>Build</b>.
-     New targets apps_clean and apps_distclean to simplify working
-     with application diretories.
+  <li><b>Build System</b>.

-      toolchain (and probably MinGW), build DOS MZ format executables (i.e.,

+
+New features and extended functionality:
+
+    * General Drivers:  Add support for (29-bit) extended CAN IDs.  Add an
+      infrastructure to support battery drivers.   Add a driver for MAX17040x
+      battery "fuel gauge".  Add support for Composite USB drivers (in
+      particular for a CDC/ACM with MSC USB composite driver).
+
+      Added a new RAM logging driver.  This will allow debug output into
+      a RAM buffer associated with a character driver at /dev/syslog.
+      Added the new command 'dmesg' to NSH that can be used to dump the
+      current contents of the log.  This is useful for systems that do not
+      have the usual serial console (for example, if you only have a
+      Telnet console with NSH).
+
+    * Networking:  Add a lower level, primitive socket interface.  Telnet
+      driver:
+
+      A New Telnet daemon was created.  It wraps a Telnet session within a
+      character driver that can serve as a "controlling terminal."  The
+      Telnet session will then be inherited by tasks created from the
+      Telnet session and the stdin/stdout from the created task will
+      still go through the same Telnet connection.
+
+    * STM32 Drivers.  PWM driver pulse count was limited to 128; now is
+      (essentially) unlimited.  Add support for (29-bit) extended CAN IDs.
+      Add support for I2C3.  The SDIO driver is (mostly) verified on the
+      STM32 F4 platforms.
+
+    * LPC17xx Drivers.  Extended the CAN driver so that the TSEG1 and TSEG2
+      bit times can be set via the NuttX configuration.  Add support for
+      (29-bit) extended CAN IDs.
+
+    * PIC32 Drivers. The PIC32 Ethernet driver is code complete (but still
+      untested).
+
+    * FTPD.  Add a new FTP server daemon.  This is based loosely on 
+      the hwport_ftpd library provided by Jaehyuk Cho.
+
+    * Library:  Add support for on_exit().  Implemented tcsetattr() and
+      tcgetattr().  Moved the old, too-smart fgets() to a new application
+      library function called readline().  Dumbed down the original fgets().
+      Add strcasestr(), avsprintf(), inet_ntop(), and inet_pton().
+      Add support to enable or disable debug output.
+
+    * Build system: Support for building a 32-bit simulation executable on
+      a 64-bit Linux machine.  Correct a dependency issue in the arch/*/src/board
+      directory.
+
+Bugfixes:
+
+    * System:  Correct PTHREAD_MUTEX_INITIALIZER
+
+    * FAT: Fix an error in the FAT statfs() reported by David Sidrane.
+
+    * STM32: Fix clock frequencies for APB2 timers.  Correct AFIO register
+      offset.
+
+    * PIC32.  Correct GPIOs used for LEDs on the Sure PIC32MX board.
+
+    * NSH.  Wait for a USB connection if a USB serial class is used to
+      interface with the host.
+
+Additional bugfixes, name changes, and other differences as detailed in the
+ChangeLog.
