Great thing about this link is that it has outlined all supported DB2 fixpacks just as one would have expected, moreover, each individual fixpack links has categorized each available packages well and is self-explanatory!

DB2 Fix Packs by version for DB2 for Linux, UNIX and Windows (having both DB2 LUW servers and clients):
I do like to hear feedback (+ve as well as -ve!); so as to get this page to as user-friendly as possible.
