The second release candidate of Arduino 1.0 is available (as of October 25, 2011):

The source code is hosted in the new-extension branch on GitHub: https://github.com/arduino/Arduino/tree/new-extension

If you find bugs, please open a new issue. For general problems or discussion, use the developers mailing list.

Environment (IDE)

  • New file extension (.ino).
  • New toolbar icons: checkmark (verify) and arrow (upload). (Nicholas Zambetti)
  • New color scheme, document icon, about image (ToDo).
  • Board name and serial port are shown in status line at the bottom of the editor. (from Wiring)
  • URLs in the sketch code are now clickable hyperlinks ( issue 148 ) (Christian Maglie)
  • Progress bar shown during compilation and upload. (from Wiring)
  • Support for uploading sketches from within the IDE: hold shift while clicking upload or select "Upload Using Programmer" from the File menu. Select programmer from the Tools menu of the IDE.
  • Verbose output (during compilation or uploading) now enabled from within the preferences dialog.

Language (API)

  • Switching to non-blocking Serial writes with a transmit buffer.
  • Serial.flush() now waits for transmission of outgoing data rather than discarding received incoming data.
  • Reimplementation of the SoftwareSerial library to support multiple ports (NewSoftSerial by Mikal Hart).
  • Removed Matrix and Sprite libraries.
  • Serial.print(byte) now prints the digits of the number as characters; use write() to send as a single byte.
  • write(), print(), and println() now return size_t (unsigned int) instead of void ( issue 551 ): number of bytes written.
  • write(str) in Print is no longer virtual, so subclasses of Print or Stream can't (but also don't need to) override it.
  • Added getWriteError(), clearWriteError(), and protected setWriteError() methods to Print; use to check for, clear, and set a write error flag.
  • Removed the ability to say "client == NULL" or "client != NULL" from Ethernet library; use "if (client)" or "if (!client)" instead.
  • Reimplementation of String class (Paul Stoffregen + additional modifications).
  • Added support for Flash-based strings using the F("string") syntax.
  • Added DHCP and DNS support to the Ethernet library (integration by Adrian McEwen).
  • Renamed Ethernet Client, Server, and UDP classes to EthernetClient, EthernetServer, and EthernetUDP to allow for simultaneous use of other networking libraries.
  • Modified UDP API:
    • beginPacket() / endPacket() for bracketing UDP packet construction
    • Inheriting from Stream, using write(), print(), and println() for UDP packet construction
    • parsePacket() for parsing incoming packets (and checking if there is one)
    • available(), read(), peek() for reading bytes of incoming packet
    • remoteIP(), remotePort() for information about incoming packet
  • Addition of IPAddress class (Adrian McEwen).
  • Modified Wire library to inherit from Stream; i.e. to use read(), write(), print(), println(), etc. Bracket calls to those functions with beginTransmission() and endTransmission().
  • Adding support for multiple open files and directory iteration in SD card library (Limor Fried).
  • Added serialEvent() function, called automatically on reception of serial data if it exists. Also, serialEvent1(), serialEvent2(), and serialEvent3() on the Mega.
  • Added find(), findUntil(), parseInt(), parseFloat(), readBytes(), readBytesUntil(), and setTimeout() to Stream ( issue 458  – Michael Margolis).
  • Updated Firmata to version 2.3 (r71): analog inputs now numbered from 14 (not 16) when used as digital pins.

Internals

  • Renamed WProgram.h to Arduino.h.
  • Pin definitions separated from the core and stored in new variants/ sub-directory. Specified by the BOARD.build.variant preference in boards.txt.
  • Added macros / constants for getting information about the properties of the board ( issue 490  and  issue 495 )

Tools

  • Updated avrdude to 5.11 (and switched to arduino programmer type from stk500).
