Circuit Board Version Differences?

I ordered a circuit board for my Hubsan X4 H107C HD, but the version number on the new board is different than the original.
New - EA4001322 V22
Original - EA4001323 V23
It appears that my original board is a later version.
Should I care? Will it work? What are the differences?

That is an option. :) They are sending me the V23 board. I guess I can build another with the spare V22 circuit board. I have enough parts at this point. To be continued...
