* <b>Changed:</b>
* - The RingBuff library code has been replaced in the XPLAINBridge project with an ultra lightweight buffer to help
* improve the reliability of the bridge
+ * - 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
*
* <b>Fixed:</b>
* - Fixed AVRISP project sending a LOAD EXTENDED ADDRESS command to 128KB AVRs after programming or reading from
