**0.4.2**
* Barebone UART module added.
* Hook branch merged.

* improved Aio module and clear bitness
* Improved Galileo Gen 2 support
**0.4.0**
* Rename to mraa
* get_platform_type function added.
**0.3.1**
* Initial Intel Galileo Gen 2 support
* mraa_gpio_isr parameters added.
* Detection of different supported platforms added.
**0.3.0**
* mraa_i2c_read now returns length of read
**0.2.9**
* Add global mraa.h & mraa.hpp headers
* usage of "gpio.h" is not legal you need to use "mraa/gpio.h" unless adding
-L/usr/include/mraa
**0.2.8**
* Added mraa_set_priority call

**0.2.6**
* C++ examples added, using c++ headers/api.
* moved to open instead of fopen in all modules
* rename mraa_check functions and made them internal to mraa only.
* removed "export" functions from api
* Intel Galileo Gen 1 (rev d) fixes, incorrect definition of some items
* SPI, implementation completed.
* I2C internal function, completed.
* PWM fix bug in period set method.
* Swig upstream can be used for building.
* No longer builds docs on default cmake, needs flag
* GPIO/PWM ownership guard prevents closing on existing pins, still can be forced.
**0.2.5**
* C++/Python/Node Enums/const names now do not contain MRAA_GPIO

* i2c read calls don't use const char* and i2c write calls do
**0.2.4**
* All mraa_ contexts now are pointers to the actual struct which is not
delcared in the header. The only end user change is that instead of
returning a type mraa_gpio_context pointer mraa_gpio_init() now returns a
mraa_gpio_context (which is actually a pointer to struct _gpio internally).
* C++ API is available, use the .hpp headers and add stdc++ to the linker
flags.
* Initial SPI implementation is provided
**0.2.3**
* mraa_aio_read_u16() -> mraa_aio_read()
* mraa_aio_read() now returns a uint16_t instead of an unsigned int
**0.2.2**
* First version with API considered 'stable'
