Marketplace Texture Pack Compatibility

Hey guys, new to UE4, but loving it! I just tried to get the
free texture pack and purchase one from the marketplace,
but it tells me that I don’t have a compatible engine (I currently
have the 4.8.1 version)…does this mean I have to get new
texture packs with every engine update? Or is there a way to
make the older packs compatible? Thanks!
