We expect people that download from our site to know the responsibilty of going back to older versions. Usually, when people download from our site it's a version they have previously used so they know what to expect from it. We don't use all the old versions here, so we cannot provide support for which one is better or not. We archive as many as old versions as we can find for people have different purposes in using them. Some use our site to research the change in technology, some use it because they don't like the newer versions.
