Modifications enabled in this version

• The remaining battery charge is now accurately detected for the Rechargeable Li-ion Battery EN-EL14a.
  With A firmware ver. 1.01/ B firmware ver. 1.01 or earlier, the number of images that can be captured (battery life) when an EN-EL14a is used is less than when an EN-EL14 is used. By upgrading A firmware to ver. 1.02 and B firmware to ver. 1.01, EN-EL14a performance is maximized so that more images can be captured (battery life) than when an EN-EL14 is used.
  
  Number of shots possible with the EN-EL14a (rated capacity:  DC 7.2 V, 1230 mAh; with D3100 A firmware ver. 1.02/ B firmware: ver. 1.01)
