It seems that the old UMV becomes UXV and the old UXV becomes OpV from # 564, but I found the following points to be worried about.

1. The old "UXV Voltage 16x Battery Buffer" is now an "Ultra Immense Voltage 16x Battery Buffer" instead of an "Overpowered Voltage 16x Battery Buffer". (3759th line of en_us.lang)

2. "Energy Converters" are not subject to change. (3894th line of en_us.lang)
