"Latest version" let me explain.
In some countries, even in Canada years ago, you could take a full auto firearm and simply by replacing the trigger group or bolt assembly turn a "Machine Gun" into a "legal" firearm. Now the RCMP SFSS examine a firearm with a view as to how easy it would be to change a firearm back to FA. This is why getting the APC passed took years and three different models. We have to explain to the manufacture how they have to build a firearm to meet our (Canadian) standards and that by simply telling me that the "naughty parts" are strictly controlled in their country and not available for sale simply does not cut it. Having learnt the hard way, from past experience, there is no point in presenting a firearm to the SFSS in the hope that it might pass, we work with the manufacture to try and get the design right the first time. So the "latest version" will have been designed to meet Canadian "standards" and then get approval first time, at least that is the plan.
