I know that when a package update appears in the repository, its older version disappears from there. But what if new version has a regression? Where can I find previous ones?
Note: I don't mean package from older distro release or anything like that. I mean the version directly preceding current, e.g. if wine-1.5.29 is current, I need wine-1.5.28 and maybe earlier ones. Of course, wine is a bad example since I can find any version on their website, but this isn't the case for all packages.
/var/cache/apt/archives is not an option because it may be occasionally cleaned by
