Any Issues With Upgrade From 4.3.4 To 4.3.5?

We recently upgraded to 4.3.4 and since we use push to eBay add-on I am considering going to 4.3.5. Should this be a straightforward process or have problems been encountered? Also interested in quality of version 4.3.5 and if bugs have been discovered. Are improved features worthwhile and is the new eBay module solid and fully functional? Would appreciate any insights shared by those who went this route. Thanks.
