+Keymap framework was updated. `fn_actions[]` should be defined as `action_t` instead of `uint16_t`. And default code for keymap handling is now included in core you just need define `uint8_t keymaps[][MATRIX_ROWS][MATRIX_COLS]` and `action_t fn_actions[]`.

 ### 0.3 Keymap Example
-The keymap is defined in the **`keymaps[]`** array, a 2-dimensional array of rows and columns corresponding to positions in the keyboard matrix. But most often the layers are defined using C macros to allow for easier reading and editing of the keymap files. To use complex actions you need to define `Fn` keycodes in the **`fn_actions[]`** array.

 This is a keymap example for the [HHKB](http://en.wikipedia.org/wiki/Happy_Hacking_Keyboard) keyboard.
 This example has three layers: the QWERTY base layer, and two overlay layers for cursor and mousekey control, respectively.

 ### 1.5 Fn key
-`KC_FNnn` are keycodes for `Fn` key which not given any actions at the beginning unlike most of keycodes has its own inborn action. To use these keycodes in `KEYMAP()` you need to assign action you want at first. Action of `Fn` key is defined in `fn_actions[]` and its index of the array is identical with number part of `KC_FNnn`. Thus `KC_FN0` keycode indicates the action defined in first element of the array. ***32 `Fn` keys can be defined at most.***
