The EEPROM stream read/write functions now use eeprom_update_byte() instead of eeprom_write_byte(), so that only changed bytes are written to EEPROM to preserve its lifespan.
Changed over the AVRISP-MKII and TemperatureDataLogger projects to use eeprom_update_byte() when writing non-volatile parameters to EEPROM to preserve its lifespan.
