Lessee: 3.5 changes...
Prerequisites: Same, except that you need 8 ranks of spellcraft and don't need knowledge(the planes). Also, you can't have Abjuration as a prohibited school (duh).
Skill list: Same (alchemy and scry have been removed).
Abilities: Same, except (!)...
Bonus metamagic feat at lv 1,4,7 and 10.
Improved metamagic has been moved to 10th level.
Send away, see ethereal, strike ethereal and hardy spirit (edit: ) and drain item have been removed.
Instead you get abilities involving metatmagic (apply metamagic to spells as they're cast by others [spellcraft check], apply metamagic after a spell is cast [spellcraft check], apply metamagic to wands) and gaining control of other people's spells (through an opposed caster level check).
(I'm afraid I'm too lazy to describe all the mechanics.)
