Is CEP 5.2 backwards compatible with Photoshop CC 2014 / 2014.1 ?

Hello all !

I saw adobe just released CEP 5.2 (http://blogs.adobe.com/cssdk/2014/10/introducing-cep-5-2-now-available.html) and I was wondering if I using the new CSInterface-5.2.js in my extension would break it if it is used in Photoshop CC 2014 / CC 2014.1 ?

Thanks in advance !
