Versions of life

Today we have different products and items and so many things. There are the big popular movies, the stars. and then there are versions.
Like versions of a car engine, software, biscuits, movies, even sometimes relationship.
Do we really categorize everything in our life on the basis of the version? Is the old version not appropriate just because a new update has just came out?
People date, then something doesn’t work out and after some time they date again and note the differences and everything, is it really the picture outside?
