Changes i have noticed.
Lore of Metal (alchemy) attribute doesnt stack beyond +3 armor save and cant be used on the same unit several times.
Lore of Death attribute is now just -1 LD instead of damage, this cannot be stacked (temporary effect).
Lore of Fire 6th spell is now +1 T 5+ wardsave and 2+ ward against flaming augument spell.
Lore of Heavens attribute can now only reroll a to hit roll, to wound, or an armor save on their turn. Not really sure how this works, i guess you can reroll one dice during the entire turn? It should stack but idk.
Lore of Heavens windblast is now better. Cannot march/use flying move, and when they roll to charge/flee/pursue the player must roll 3 dice and remove the highest one (like cold-blooded except negative).
Lore of Light attribute gives holy attacks and 1+ LD, doesnt stack.
Lore of shadows attribute gives a 10 flying move instead of 12 (focused).
Pit of shades cause multiple wounds D3+2 no armor or reg saves allowed.
Mindrazor gives armor piercing (1) and automatic wounds.
Same usual attribute on lore of high magic (now Path of Valour).
Tempest from highmagic is now called "Shield of the White Tower", gives a 6+ wardsave which can stack with other wards to a max of 3+ augument (not focused).
