Changes

This page lists major changes to the Arduino core, libraries, and environment. For details, see the release notes.

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.

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.

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.

Added the Firmata library, which provides a standard protocol for serial communication.
Added Ethernet library.
Added Servo library.
Added LiquidCrystal library.

Corrections, suggestions, and new documentation should be posted to the Forum.
