Flipendo,
this isn't exactly a new thread, but they should work in any of those versions (or, it's probably not an issue at this point -- we're already a good several revisions ahead of this:
There are plenty of maps that works in this pack, however, they DID NOT work well under 0.6 since there were TONS of missing textures. Now the maps works better, and there are a few handfuls of maps to use. I am currently working on a re-pack/extension of this map-pack with screenshots of every single map, but I only have so much time...I will let you know when I'm done.
(0.7.0 era, so you know )).
