ARDUINO BETA 1.5.1 - 2012.11.05

* Merged changes coming from stable release of Arduino IDE 1.0.2.

[arduino core]

* added support for yield() function in Arduino Core. This is a

preliminar step for experimenting with cooperative Schedulers.

[ide]

* Simplified boards menu selection. (new boards.txt file format with

custom sub-menus).

* Fixed "FAT" (multi-platform) library detection. This bug caused

many libraries to be detected as 'invalid'.

[sam arduino core]

* attachInterrupt() and detachInterrupt() are now working.

* Fixed macros to query low level GPIO registers:

digitalPinToBitMask(), digitalPinToTimer(),

portOutputRegister, portInputRegister()

* Fixed analogWrite() on DAC0/1 when writing on both DACs

(thanks to smay4finger)

[firmwares]

* Added firmware for atmega16u2 on Due Board.

ARDUINO BETA 1.5 - 2012.10.22

* First release for the unified IDE for both AVR 8-bit and ARM 32-bit

(SAM3 CPUs) architectures.

Board.

* Everything is in beta, most features or libraries are still missing
