Re: AIX Upgrade, what is regression?



This package contains one or more fixes that are known to cause regression.
The regression may affect your system. Emergency fixes may be available for
these known problems from the Interim fix management page. Reference APAR
number(s) IY84335.

What do you think "regression" means? Is that some form of testing or is
that some sort of fallback?

It means that a previously functional feature is known to a problem.

"Regressions tests" are intended to catch regressions before the product is released.

In this case, searching on the IBM page for IY84335 leads to:

Odds are, this wouldn't affect you. But it's nice to be forewarned.
