三月底Arduino發布了0011版的開發環境，對Mac OS X的支援度更好，也增加了一些新的function。以下是官方網頁上寫的release note。
* Improved reliability for uploading to Arduino BT.
* Better support for bootloader burning with a parallel programmer.
* Fixed Find in Reference.
* Added map() function for mapping values from one range to another.
* Added analogReference() function.
* Added interrupts() and noInterrupts() functions.
* Added degrees() and radians() functions.
* Added timeout parameter (in microseconds) to pulseIn(); default is 1 second.
* Support for uploading sketch using a programmer.
* Improved detection of functions that need prototyping.
* Placing function prototypes after #include’s and #define’s.
* No longer moving #include statements to the top of the sketch.
* Can now drag .pde files onto the Arduino dock icon on Mac OS X. Thanks to Peter Sgouros.
* New script for downloading the reference from Tom Pollard. Thanks Tom!
* Miscellaneous Mac OS X and other patches from Wim Lewis. Thanks Wim! * Updated Mac OS X FTDI drivers.
我個人是對那些新增的functions比較有興趣啦。晚點來研究看看。
