Add initial whats-new.rst.

It needs a lot more work before being done, obviously. Refer to it
prominently from the index page, and add it to the contents tree.

+What's New
+==========
+
+.. FIXME [RELEASE] finish.
+
+This page tracks updates to libmaple and MapleIDE.
+
+.. contents::
+   :local:
+   :depth: 1
+
+v0.0.13
+-------
+
+**General Changes**
+
+.. We started doing this as we updated the docs on 29 Jun 2012, so
+.. updates before then need to be pulled from libmaple's Git logs.
+
+- Additional STM32 support: for this release, libmaple was taught
+  how to target STM32F1 value line (thanks to Anton Eltchaninov) and
+  STM32F2 series microcontrollers.  It learned a huge bag of new
+  tricks as a result, so this list is only a summary of the most
+  important changes.
+
+- New include style: You should now include libmaple and Wirish
+  headers like this (respectively)::
+
+      #include <libmaple/libmaple.h>
+      #include <wirish/wirish.h>
+
+  The old include style (e.g. ``#include "libmaple.h"``) is now
+  **deprecated**, and will **break in the next release**. This is more
+  standard usage for libraries, and was necessary to e.g. allow for
+  implementing a Wiring/Arduino-style SPI library (which is included
+  as ``#include "SPI.h"`` and clashes with :ref:`libmaple-spi` on
+  case-insensitive filesystems like OS X's).
+
+**Wirish**
+
+- Wire I2C library: New, improved, and more Arduino-compatible
+  :ref:`Wire <libs-wire>` library, thanks to Trystan Jones.
+
+**libmaple proper**
+
+Better documentation: The old documentation for libmaple's C layer did
+little more than list the Doxygen comments in the source code. It now
+includes explanatory material and usage notes. See
+:ref:`libmaple-apis`.
+
+.. FIXME [0.0.13] this is ugly
+
+Changes by header follow.
+
+.. list-table::
+   :header-rows: 1
+   :widths: 1 10
+
+   * - Header
+     - Changes
+
+   * - :ref:`libmaple-rcc`
+     - :ref:`rcc_clk_init() <rcc-rcc_clk_init>` is deprecated. Use
+       :ref:`rcc_configure_pll() <libmaple-rcc-rcc_configure_pll>` as
+       the basis for a portable replacement; see the
+       ``rcc_clk_init()`` docs for a porting guide.
+
+   * - :ref:`libmaple-libmaple_types`
+     - Various new attributes and type qualifiers.
+
+   * - :ref:`libmaple-adc`
+     - New :ref:`adc_enable_single_swstart()
+       <adc-adc_enable_single_swstart>` and :ref:`adc_config_gpio()
+       <adc-adc_config_gpio>`, for portably enabling ADC peripherals
+       and their associated pins for use with :ref:`adc_read()
+       <adc-adc_read>`.
