 * Each open sketch gets built in its own folder, allowing the IDE to recycle previous compilations and being much faster
 * "Go to line": CTRL+L or Edit > Go to line... will open a dialog where you can type the line number where you want the editor to jump to
 * Added boards.local.txt support: like platform.local.txt, allows to enrich a boards.txt definition without modifying the original file. Thanks @Wackerbarth
+* Library to library dependencies: when your sketch imports a library, and that library uses another, the IDE will find out without you having to add a useless #include to your sketch

 * Bridge: YunClient.connected() returns true if there are bytes available for read. Thanks @RobAtticus
