The main differences include support for multiple sketch windows open simultaneously and a dedicated window for the serial monitor. <p class='vspace'></p></li><li><strong>Icons</strong>: The icons and about images were updated. <p class='vspace'></p></li><li><strong>Arduino.app</strong>: The Mac OS X version of Arduino is now a .app file packaged in a .dmg. <p class='vspace'></p></li><li><strong>Libraries</strong>: Support was added for third-party libraries in the <em>SKETCHBOOK</em>/libraries directory. This allows user-installed libraries to persist across upgrades of the Arduino software. <p class='vspace'></p></li><li><strong>Servo</strong>: The servo library was rewritten to allow support for up to 12 servos (on any pins) and up to 48 on the Mega. <p class='vspace'></p></li><li><strong><span class='wikiword'>LiquidCrystal</span></strong>: The begin(), cursor(), noCursor(), blink(), noBlink(), display(), noDisplay(), scrollDisplayLeft(), scrollDisplayRight(), autoscroll(), noAutoscroll(), leftToRight(), rightToLeft(), and createChar() functions were added. </li></ul><p class='vspace'></p><h3>Changes in Arduino 0016</h3> <ul><li>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. </li></ul><p class='vspace'></p><h3>Changes in Arduino 0015</h3> <ul><li>Support for the Arduino Mega. </li></ul><p class='vspace'></p><h3>Changes in Arduino 0013</h3> <ul><li>Support for printing floats was added to the Print, Serial, and Ethernet library Client and Server classes. <p class='vspace'></p></li><li>The word type and word(), bitRead(), bitWrite(), bitSet(), bitClear(), bit(), lowByte(), and highByte() functions were added. </li></ul><p class='vspace'></p><h3>Changes in Arduino 0012</h3> <ul><li>Added the Firmata library, which provides a standard protocol for serial communication. <p class='vspace'></p></li><li>Added Ethernet library. <p class='vspace'></p></li><li>Added Servo library. <p class='vspace'></p></li><li>Added <span class='wikiword'>LiquidCrystal</span> library. </li></ul><p><a class='wikilink' href='index.html'>Reference Home</a> </p> <p class='vspace'></p><p><em>Corrections, suggestions, and new documentation should be posted to the <a class='urllink' href='http://arduino.cc/forum/index.php/board,23.0.html' rel='nofollow'>Forum</a>.</em> </p> <p class='vspace'></p><p>The text of the Arduino reference is licensed under a <a class='urllink' href='http://creativecommons.org/licenses/by-sa/3.0/' rel='nofollow'>Creative Commons Attribution-ShareAlike 3.0 License</a>.
