ARDUINO 1.0

[environment]

* The file extension for sketches has changed from .pde to .ino, to avoid
conflicts with the Processing software ("ino" are the last three letters
in "Arduino").

* There are a new set of toolbar icons, including a checkmark icon to
verify (compile) a sketch and an arrow for upload. The serial monitor
icon has moved to the right of the toolbar. Also, shift-clicking the
upload icon now uploads using a programmer (selected in the Tools menu).
You can still enable verbose output in the preferences dialog. (Icons
were designed by Nicholas Zambetti.)

* ThereÔÇÖs a new color scheme and about image for the IDE (by ToDo.to.it).

* The name of the currently selected board and serial port are now shown
at the bottom of the editor. (Code from Wiring.)

* A progress bar is displayed during compilation and upload. (from Wiring.)

[core / libraries]

* Serial transmission is now asynchronous - that is, calls to
Serial.print(), etc. add data to an outgoing buffer which is transmitted
in the background. Also, the Serial.flush() command has been repurposed
to wait for outgoing data to be transmitted, rather than dropping
received incoming data.

* The behavior of Serial.print() on a byte has been changed to align it
with the other numeric data types. In particular, it will now print
the digits of its argument as separate ASCII digits (e.g. '1', '2', '3')
rather than a single byte. The BYTE keyword has been removed. To send a
single byte of data, use Serial.write() (which is present in Arduino 0022
as well).

* The Serial class (as well as other classes inheriting from Stream, like
EthernetClient, SoftwareSerial, Wire and more) now contains functions
for parsing incoming data, based on the TextFinder library by Michael
Margolis. They include find() and findUntil() to search for data,
parseInt() and parseFloat() for converting incoming characters into
numeric values, and readBytes() and readBytesUntil() for reading
multiple bytes into a buffer. They use a timeout that can be set with the
new setTimeout().

* The SoftwareSerial class has been reimplemented, using the code originally
written for the NewSoftSerial library by Mikal Hart. This allows for
multiple simultaneous instances, although only one can receive at a time.

* Support has been added for printing strings stored in flash (program
memory) rather than RAM. Wrap double-quoted strings in F() to indicate
that they should be stored in flash, e.g. Serial.print(F("hello world")).

* The String class has been reimplemented as well, by Paul Stoffregen. This
new version is more memory-efficient and robust. Some functions which
previously returned new string instances (e.g. trim() and toUpperCase())
have been changed to instead modify strings in place.

* Support for DHCP and DNS has been added to the Ethernet library, thanks
to integration by Adrian McEwen. Most classes in the Ethernet library
have been renamed to add a "Ethernet" prefix and avoid conflicts with
other networking libraries. In particular, "Client" is now
"EthernetClient", "Server" is "EthernetServer", and "UDP" is
"EthernetUDP". A new IPAddress class makes it easier to manipulate
those values.

* The UDP API has been changed to be more similar to other libraries.
Outgoing packets are now constructed using calls to the standard write(),
print(), and println() functions ÔÇô bracketed by beginPacket() and
endPacket(). The parsePacket() function checks for and parses an
incoming packet, which can then be read using available(), read(), and
peek(). The remoteIP() and remotePort() functions provide information
about the packetÔÇÖs origin. (Again, thanks to Adrian McEwen for the
implementation.)

* The Wire library has also been modified to use the standard read() and
write() functions instead of send() and receive(). You can also use
print() and println() for outgoing data.

* The SD library now supports multiple simultaneous open files. It also
provides the isDirectory(), openNextFile(), and rewindDirectory()
functions for iterating through all the files in a directory. (Thanks
to Limor Fried.)

[boards / firmwares]

* Added the Arduino Mini w/ ATmega328.

* Added Windows drivers (.inf files) and 16U2 firmware (.hex files) for
the rev. 3 boards (Uno, Mega, and Mega ADK).

[internals]

* The WProgram.h file, which provides declarations for the Arduino API,
has been renamed to Arduino.h. To create a library that will work in
both Arduino 0022 and Arduino 1.0, you can use an #ifdef that checks
for the ARDUINO constant, which was 22 and is now 100. For example:

#if defined(ARDUINO) && ARDUINO >= 100
#include "Arduino.h"
#else
#include "WProgram.h"
#endif

* The write(), print(), and println() functions in Stream now return a
size_t (instead of void). This indicates the number of bytes actually
written by the function. Any classes that inherit from Stream will need
to change accordingly. Additionally the write(str) function has been
given a concrete implementation ÔÇô it calls write(buf, len) - so
sub-classes don't need to (and shouldn't) implement it.

* There are new abstract base-classes for Client, Server, and UDP to
provide portability across networking libraries.

* The pin definitions for the Arduino boards (i.e. the mappings from pin
numbers to port register / bit pairs) is now stored in a sub-folder of
a new variants/ folder in the hardware folder. The variant to use for
a given board is specified by the BOARD.build.variant preference in the
boards.txt file.

* The new, variant-specific pins_arduino.h files now provides additional
macros with information about the characteristics of the board (e.g.
the locations of the SPI and TWI pins, and the number of digital and
analog pins).

* The avrdude included with the Mac and Windows versions of the Arduino
software has been upgraded to avrdude 5.11 (from an Arduino-specific
version of avrdude 5.4). The software now uses the "arduino" programmer
type in place of "stk500v1" for uploading to most Arduino boards.
