Need to update a datapack from 1.21.4 to 1.21.5

So I downloaded this datapack that I use in my world, but because the owner of the project doesn't actively work on it im worried a new version won't come out for quite a while. I've pretty much never done any coding, but was wondering if there's anything I need to do for it to function properly in 1.21.5. The datapack is Blaze and Caves torture edition, it's found on planet mc.
