It is more than two years old. After RH9, Red Hat Linux was superseded by two products: Red Hat Enterprise Linux, which you have to pay for and doesn't get updated and is very stable; and Fedora Core, which is free and constantly updated (which means it's not as stable). So if you want something like Red Hat 9 but has new stuff, then you should get Fedora Core. If you really prefer to stay with Red Hat 9, you should read
this page to configure updates.
