Well, I eventually found a Canon contact point for a software related issue. This is their response:
In response to your enquiry regarding software for your EOS 700D, we regret to inform you that the software for this operating system have not currently been developed.
Canon are due to be working on the development of software updates when the operating system has been officially released and will be available as soon as possible. Unfortunately we do not have a release date.
We therefore advise to consult our download centre, as they will be available to download and install from here, when released. Please find the link to this section below.
So, there we go!
