IBM's certificates are good only for the version of the technology you're certified on. In theory, they do 'expire' when a new verson comes out (IBM usually issues a retirement notice on the Certification site.)
That being said, I tend to still list the 'expired' ones as I have had customers still using an older version that I am certified on years after the expiration notice came out...
