Narrative:
Regarding flight from yyz to atl on apr/xa/00. The left and right pack temperature controls were both written up with problems in the logbook. When we referred to the MEL we missed the note on the FL250 altitude restr. I understand that the first dispatch release and flight plan were for FL240, however, we never received that release. We only received release #2 which planned and released us for a flight at FL350. We operated the flight as if there were no altitude restr. We had a completely normal flight with no pressure or temperature control problems.
