Increased number of possible dialog buttons from 5 to 12.
Added blank entries for all units that don't normally have abilities or attacks, allowing a user to potentially add these through the Unit Editor.
Added Unit Editor field to set unit sounds to that of another unit type.
Reorganized limits on pre-placed neutral units. Neutral hostile buildings now count towards the "unit" limit of 512, and only passive buildings count towards the "building" limit of 96.
Fixed bug where map auto-save could bypass object limit checks.
Fixed Sound Editor bug that would sometimes delete an imported sound file from the map if it was imported from outside the War3 directory and the Test Map feature was used before the map was saved.
Fixed force issue that would cause Force 11 when you selected Force 10 for a trigger in the editor.
Humans: Brilliance Aura has been reworked, and is no longer % based. It now adds a fixed amount of mana per second to units under its power -- .75, 1.5, and 2.25 respectively by level. While it's just as effective with mass spell-casters, players will find it is less powerful (though still exceedingly useful) with Heroes.
Undead: Gargoyles' ground attack was substantially upgraded. They now do 21-24 damage, up from 16-18 damage. They also have less armor (3, down from 5), but also hit harder against air units, doing 51-63 damage, up from 46-57 damage. Note that they are still just as effective against air units as they were before, but their ground attack has been much improved.
Undead: Death Pact now costs 50 mana (down from 75), and can be cast twice as frequently as before (15 seconds cooldown from 30).
Undead: Lich Heroes now have far more hit points, as they now have 15 str + 2/level, up from 13 + 1.6/level.
Undead: Frost Armor is now an auto-cast spell which will target units under attack if auto-casting is enabled. Frost Armor also costs less mana - 40 down from 50.
Undead: The Spirit Tower Upgrade now costs 160/40, up from 120/40.
Orcs: Headhunters have more hit points (350, up from 280), but also strike more slowly.
Orcs: Stasis Trap no longer stuns friendly units, but has a shorter duration (6 seconds, down from 12 seconds). Stasis Traps, when they are set off, also destroy other Stasis Traps within their area of effect.
Orcs: Kodo Beasts now have 1000 hit points, up from 790 hit points. They also attack more slowly than before.
Night Elves: Sentinel can now be removed from a tree with various dispels (Wand of Negation, Dryads, etc.), as well by attacking the tree with a peon or siege unit (previously, the tree had to be destroyed - now it merely has to be damaged).
Night Elves: Thorns is now a %-based ability that reflects 10%, 20% or 30% of melee damage dealt by level.
Night Elves: Wisp's sight radius increased by 25%.
Night Elves: Detonate now does 225 damage against summoned creatures, up from 150.
Night Elves: Non-tree buildings now have 5 armor, up from 2.
Night Elves: Ballistae now have an "Attack Ground" command.
Night Elves: Force of Nature cooldown reduced to 20 seconds, down from 30 seconds.
Night Elves: Treants now last 60 seconds, down from 75 seconds.
Night Elves: Eating trees now gives a constant, non-stacking healing effect for 10 seconds.
Night Elves: Moon Wells now spend mana on health and mana replenishment separately. For instance, if you sent a 0-mana, nearly dead Demon Hunter to a Moon Well, and the Moon Well had 100 mana, your DH would gain 25 mana, and 100 health. Before, the Hero would gain 200 health and 50 mana. This change does not affect the benefits of healing a unit without mana.
Creeps: All melee creeps in between levels 1 and 5 are slightly more powerful.
Creeps: All creeps of level 6 or higher now have Hero magic resistance.
Creeps: Creeps of level 7 or higher will behave more intelligently in general.
Creeps: All creeps of level 7 or higher now deal Chaos damage.
Creeps: Level 10 Dragons no longer have spell immunity.
Creeps: Many minor creep balance tweaks to damage and abilities.
Creeps: Mercenaries are now more accurately priced in general, which in most cases amounts to price decreases.
