The term "new set" is used in various contexts, but generally refers to a fresh or recently introduced collection of items. In some cases it may refer to a new group or selection of things that are different from what has come before. For example, if someone were to say they had just purchased a new car, the phrase "new set" would imply that this is an entirely new vehicle and not simply one that was previously owned by another person. In other contexts, such as in music or comedy, it may refer to a completely different performance or routine from what has been done before.
