Default [Q] CM 10.2 - Google Play 4.6.16 - how to update?


I'm still using CM 10.2, how can I update google play to 4.6.16? Do I have to reflash new gapps (coudnt find a new package)?. I saw some apks on androidpolice but is it safe to install it? I wouldn't bother the whole process but since yesterday I've been facing battery drain caused by google services. It happens every time google releases something new.
