"The announcement stated that "any users of the 2.6.25 kernel
series are STRONGLY encouraged to upgrade to this release," but did
not say why; none of the patches found in this release were marked
as security problems. As it happens, there were security-related
fixes in that update; some users are upset that they were not
explicitly called out as such. They have reached the point of
accusing the kernel developers of hiding security problems."
