For x86_64 this update still contains bdii v. 4.0.0-5. However for x86 this update contains bdii v. 4.0.1-0. As bdii v. 4.0.1-0 has important bug fixes we recommend to install bdii v. 4.0.1-0 also on x86_64 nodes. To do this please go to the corresponding x86 web page for the x86_64 node type you are installing and get the bdii v. 4.0.1-0 rpm from the rpm list.
