EROM version

Hi there I am aware that there is EROM ver R3A022 available for new K800i or K810i. I just saw that you have R3B021 on your EROM download. Is it even newer than R3A022?
Do you know what is the improvement?
Can I use WotanServer to update my EROM with the version that I downloaded from here? Thanks!

Press and hold 2+5 in wotanclient

We should press 2+5 or 2+5+c ?
