Changes
=======
This page lists major changes to the Arduino core, libraries, and
environment. For details, see the
`release notes <http://arduino.cc/en/Main/ReleaseNotes>`_.
Changes in Arduino 0017
~~~~~~~~~~~~~~~~~~~~~~~
- **Environment**: The code base for the Arduino development
environment was largely re-written to bring it back into sync with
Processing (1.0.3). The main differences include support for
multiple sketch windows open simultaneously and a dedicated window
for the serial monitor.
- **Icons**: The icons and about images were updated.
- **Arduino.app**: The Mac OS X version of Arduino is now a .app
file packaged in a .dmg.
- **Libraries**: Support was added for third-party libraries in
the *SKETCHBOOK*/libraries directory. This allows user-installed
libraries to persist across upgrades of the Arduino software.
- **Servo**: The servo library was rewritten to allow support for
up to 12 servos (on any pins) and up to 48 on the Mega.
- **LiquidCrystal**: The begin(), cursor(), noCursor(), blink(),
noBlink(), display(), noDisplay(), scrollDisplayLeft(),
scrollDisplayRight(), autoscroll(), noAutoscroll(), leftToRight(),
rightToLeft(), and createChar() functions were added.
Changes in Arduino 0016
~~~~~~~~~~~~~~~~~~~~~~~
- New functions for writing a string, write(str), or buffer,
write(buf, len), were added to the Print, Serial, and Ethernet
library Client and Server classes.
Changes in Arduino 0015
~~~~~~~~~~~~~~~~~~~~~~~
- Support for the Arduino Mega.
Changes in Arduino 0013
~~~~~~~~~~~~~~~~~~~~~~~
- Support for printing floats was added to the Print, Serial, and
Ethernet library Client and Server classes.
- The word type and word(), bitRead(), bitWrite(), bitSet(),
bitClear(), bit(), lowByte(), and highByte() functions were added.
Changes in Arduino 0012
~~~~~~~~~~~~~~~~~~~~~~~
- Added the Firmata library, which provides a standard protocol
for serial communication.
- Added Ethernet library.
- Added Servo library.
- Added LiquidCrystal library.
