Whoops, we forgot to post up about this. Arduino 18 is out! There’s improved support for 3rd party hardware, nice…

0018 – 2010.01.29

[core / libraries]

• Added tone() and noTone() functions for frequency generation.
• Added Serial.end() command.
• Added precision parameter for printing of floats / doubles.
• Incorporated latest version of Firmata.
• Fixed bug w/ disabling use of the RW pin in the LiquidCrystal library.
• No longer disabling interrupts in delayMicroseconds().
• Fixed bug w/ micros() returning incorrect values from within an interrupt.
• Fixed bug that broke use of analog inputs 8-15 on the Mega.

[environment]

• Synchronized with the Processing 1.0.9 code base, bringing various fixes, including to a bug causing saving to fail when closing the last sketch.
• Added support for third-party hardware in the SKETCHBOOK/hardware folder, mirroring the current structure of the hardware folder in Arduino.
• Added Ctrl-Shift-M / Command-Shift-M shortcut for serial monitor.
• Hold down shift when pressing the Verify / Compile or Upload toolbar buttons to generate verbose output (including command lines).
• Moving build (on upload) from the applet/ sub-folder of the sketch to a temporary directory (fixing problems with uploading examples from within the Mac OS X disk image or a Linux application directory).
• Fixed bug the prevented the inclusion of .cpp and .h (or .c and .h) files of the same name in a sketch.
• Improved the Mac OS X disk image (.dmg): added a shortcut to the Applications folder, a background image with arrow, and new FTDI drivers.
