Is There a Difference Between 4.1 and 4.2 Free Contents?

As I transition to 4.2, I notice that some free contents from 4.1 needed to be downloaded again. I reckon the Example Content has an added content. But what about the others, like Elemental, Memory, and Tappy Chicken?

Does this mean that I have to download them again?

When Epic Games releases a new version of the engine, they may elect to add to or change a piece of marketplace content. When they do, it comes as a separate version. This allows Epic to release updates to, say, Tappy Chicken that take advantage of new features introduced in a new version of the engine while at the same time still making Tappy Chicken available to developers who are still using an older version of the engine.

Ok… So might as well redownload all those items again… Thanks!!!
