Added the ability to change sacrifices for spells; details in the Admin Guide.
It is now impossible to sacrifice for spells that you don't have permission to use.
Replaced the broken spellcraft.spells.* with spellcraft.allspells.
Items dropped by food will sometimes be impossible to pick up.
summonwolf is broken; summoned wolves will not attack their target unless the caster attacks it first (that is, they act like normal wolves). However, the spell otherwise functions normally; summoned wolves vanish once their target dies or on server restarts.
fissure still causes blocks that depend on the side of another block (i.e., side-torches) to fall off about half the time.
