Should I upgrade to LR6 ?
Lightroom 6 requires a 64-bit operating system. That probably isn't a problem for you but it is something that should be pointed out because there are a few 32-bit systems still out there. Lightroom 6 will still be updated to support new cameras until the end of the year, but then that will be the end. The program will continue to be sold for some time, but will receive no enhancements or improvements. If operating systems change and computer configurations change in such a way that the program no longer works then you will have to find something else to work with. But your images will still be yours and will be available to you.
