As many users have already noticed, we spent a significant part of the past two weeks upgrading the version of VaultWiki installed on our own site to VaultWiki version 4. It took quite a while due to the somewhat unorthodox setup we have, and due to the modifications we use internally.
Nevertheless, the web site is now running VaultWiki 4, and the wiki is turned on for all to see, test, and demo. Keep in mind that currently only VaultWiki 3 is available for sale, so what you now see on this site is only a preview of what's to come very, very soon. It is not completely representative of the product you can download today.
If you were going to purchase VaultWiki 3 now anyway, and now you're afraid you'll have to pay for VaultWiki 4 again in a very short time, don't be. You don't have to wait for VaultWiki 4. Like other updates, the upgrade to version 4 will be included in the purchase price of version 3.
