latest xyzware update

Noticed that there is a new version of xyzware ver: 1.0.34.1 dated 3/3/2015. Is it me or are version numbers going down in number? Prior release was 1.1.34.8. Can anyone tell me what the heck is going on. What is the latest we should be using? Just realized that was for XP. I'm running under Win 7. Do i go with 1.1.34.7 or 1.1.34.8. What is the latest firmware that accompanies these versions?
