selart detected a package upgrade

[Ian Malone]

I hit yes on a round of updates for F8 this morning,
while installing was taking place I twice got the
message box "sealert detected a package upgrade,
rebooting now" and a thirty second countdown.  This
didn't strike me as great since the system was still
halfway through restarting packages (it's also
abysmally short if I had been doing something else).

Does anyone know why this should have started
happening now?
