From Release Notes: ARDUINO 1.6.7 - 2015.12.17 [ide] * New arduino-builder: faster, better prototype generation and library discovery logic, and more. See https://github.com/arduino/arduino-builder/compare/1.0.5...1.3.9 * Serial plotter now allows to plot multiple values at once. Thanks @henningpohl * New translations * Added support to file:// protocol for boards manager URLs * Portable sketchbook folder can now be any arbitrary location * Fixed a bug that caused Boards Manager to install the same tool twice or more, thus wasting disk space, if other cores where using tools delivered by arduino * Fixed various Boards manager glitches, in particular when removing a board * Windows: Arduino IDE icon is now in high definition, bye bye that blurry icon * Remote upload without SSH is now supported (allows OTA upload for many 3rd party boards). Thanks @me-no-dev. [libraries] * SPI: Added SPI.transfer16(...) function to SAM core. * Ethernet, WiFi, SoftwareSerial: Fixed flush() behaviour: the flush function is no more dropping the receive buffer, as per 1.0 API specification. Thanks @drmpf [core] * Fixed wrong timings for HardwareSerial::flush() in SAM core. Thanks @borisff * Stream: Optional lookahead and skipChar options added to parseInt and parseFloat, parseFloat also support parsing floats without a leading 0, Stream::find(char) added to SAM. Thanks @Chris--A. * Leonardo/Micro (and other atmega32u4 based boards) now have SerialUSB alias for Serial * Leonardo now has LED_BUILTIN_RX/TX definitions in variant file. Thanks @NicoHood Thanks.
