Should I update from v2.0.7 to 2.2.0 ?

Hi,

Should I update RekordBox from v2.0.7 to 2.2.0 & should I update my CDJ 2000'S from v4.11 to v4.20

Reason for my question is I haven't really been having any issues with being on RekordBox 2.0.7 &  my CDJS on my CDJ 2000'S on v4.11, so I didn't bother running the updates. However couple weeks back had a complete stop on a track which normally plays all OK.

**This is my setup: 2 x CDJ 2000'S (VERSION 4.11) linked Via 10/100mps Netgear Switch & MacBook Pro 2011.

**Obviously I know normally updates improve things however didnt want to make the mistake of making things worse. The setup I have on the firmwares I have at the moment have been the most stable so far, as I used to have loads of issues in the past with tracks just stopping randomly so hence my doubt/concern in updating.

Any thoughts?
