PHP upgradr, worried about compatibility

[Elecco]

So, I just received email that the company which provides me the server space etc. is going to upgrade lots of stuff on its servers, here are listed what is upgraded and to which version:

 

PHP 5.4

Perl 5.15

Python 2.7

 

I have Prestashop 1.5.4.0 in use, should I be worried? I know that there is a newer version out already, but so far I haven't upgraded because I fear it will break stuff, I also have paid module in use and I'm not so sure if it's compatible.

Here is the official Backward Incompatible Changes;

in light review you 'should' not experience any problems.

 

probably the best thing to do would be to replicate your shop on a localhost running PHP 5.4, if you have time

 

else you should be prepared to have your ps errors enabled if you do experience problems and a php programmer than can fix any  little nicky issues.

if you are not sure how to run on error review this
