I just read that new databases created after june 30, 2015 will only work with vuforia V4.0. We have couple of projects where we have to update the database after this date, because of changes of live content. Many projects are build in the 'native C++' style, which means with CPP code and libQCAR.so libaries. In the past we have tried to rewrite to code to the 'new java' style without success (at least in a short time).
Will the 4.0 SDK backward compatible with the 'native C++' style of programming?
Thanks, happy programming from Holland!
