Changed lines 11-12 from:

If false, endTransmission() sends a restart message after transmission. The bus will not be released, which prevents another master device from transmitting between messages.

to:

If false, endTransmission() sends a restart message after transmission. The bus will not be released, which prevents another master device from transmitting between messages. This allows one master device to send multiple transmissions while in control.

Changed lines 22-23 from:

stop : boolean. true will send a STOP releasing the bus. false will continually send start requests, keeping the connection active.

to:

stop : boolean. true will send a stop message, releasing the bus after transmission. false will send a restart, keeping the connection active.

Changed lines 5-10 from:

Ends a transmission to a slave device that was begun by beginTransmission() and actually transmits the bytes that were queued by write().

Starting with Arduino 1.0.1, endTransmission() will accept a boolean argument changing its behavior for compatibility with certain I2C devices. If true, it will send a STOP, releasing the I2C bus after the transmission. If false, the function will send a repeated start message so the next transmission with the master device will happen automatically. When false, the bus will not be released between transmissions.

The default value is true, same as previous versions of the function.

Ends a transmission to a slave device that was begun by beginTransmission() and transmits the bytes that were queued by write().

As of Arduino 1.0.1, endTransmission() accepts a boolean argument changing its behavior for compatibility with certain I2C devices.

If true, endTransmission() sends a stop message after transmission, releasing the I2C bus.

If false, endTransmission() sends a restart message after transmission. The bus will not be released, which prevents another master device from transmitting between messages.
