Fixpak 14 for DB2 UDB v8 is out
It contains, among other things, a fix for the Daylight Savings Time (DST) change. USA and Canada will change the effective date of DST in March, 2007. By that time you should make sure the operating system supports the change and install the fixpak. This also concerns DB2 9, for which Fixpak 2 is available.
The complete list of fixes can be found here.
