I was told that this database also contains user credentials that were unknown to Have I Been Pwned, so maybe there were also some newer or lesser known breaches compiled in. In any case it is a valuable resource when you don't trust services like HIBP. That database contains some ancient user credentials of mine, I should probably check if family and friends are in there as well and if they are, urge them to change those passwords in case they are still using them somewhere.
