Dungeon crawl sources beyond 400b26

Created by: Trilarion

The Wikipedia entry (copied to many other places) for Linley's Dungeon Crawl (https://en.wikipedia.org/wiki/Linley%27s_Dungeon_Crawl) speaks of a version 4.1.0 but the link goes only to the official site where no such version can be found. Even stranger, there is a version 400b26e070t mentioned but without any source.

I cannot find neither of these versions. I recommend to ask the maintainer of http://www.dungeoncrawl.org/ and within the Dungeon Crawl community (maybe Dungeon Crawl Stone Soup community) if they know more about it.
