If you are a Khajiit, Nord or Imperial, you need to open the console, type Player.SetRace AbcRaceVampire, close and reopen the console, then type Player.SetRace AbcRace; or the other way round if you're a vampire. otherwise your abilities will not update correctly. In some circumstances, Nords and Imperials may not update at all. Sry bub.

- Included the Modern Brawl Bug Fix scripts with Imperious instead.
- Racial quests now have the actual name of the race.

Altmer
- Renamed Supremacy -> Flawless Perfection.

Argonian
- Reworked Aquatic Pigments -> Amphibious, granting a short duration sneak bonus and long duration movement speed bonus after swimming.
- Caustic Spit: increased armor penalty from 400 -> 600. (Magic resist penalty remains 75%.)

Bosmer
- Beast Tongue: backported the Ordinator teleport mechanic whereby if you are separated by more than 500 feet (read: entered or left an interior), you can stand still when out of combat to call the companion to you. (This effect is attached to the ability in your effects list when you have an animal companion, so you may need to release and charm it to reset this ability.)

Dunmer

- Brawl detector is now more accurate and will not prevent the use of active abilities from a random point in time until your first brawl.

No magic! The following abilities will now recognise brawls* and disable themselves accordingly, even without using the MCM:
- Altmer: Contingency (Enter Combat and Draw Weapon events)
- Altmer: Living Arcana
- Bosmer: Harrier
- Breton: Grail of Betony
- Breton: Stones of Galen (Serpent)
- Dunmer: Ancestral Guardian
- Dunmer: Whispers
- Imperial: Close the Ranks
- Imperial: Imperial Virtues
- Nord: Challenge
- Orc: Berserk
- Orc: Bloodlust
- Redguard: Dust Storm
You may still need the Brawl Bugs Patch, but you need it anyway if you intend to play Skyrim.
