Last leftover from the old mod, pretty much:

G4. Principle: Garrisons should not be a different # of units other similar factions have for the same building, without good reason. Change: Extra heavy infantry (Sword Follower unit) removed from Boii city/town garrisons. Elite Persian Foot Archers removed from Parthian city/town garrisons. 2 lines removed. From BruceR

A couple more left overs from patch 16 Data Typos have been added back in as they were found:

G. Armed Citizenry Units/Unit Groups table...
G2. Principle: Garrisons should not be a different # of units other similar factions have for the same building, without good reason. Change: Replacing Spear Warriors with Bloodsworn (Suebi) in Artisan building line garrisons prevents double-sized garrisons for Nervii. 1 line changed. From BruceR
G3. Principle: Buildings should not get less effective as you increase their level. Change: Colchis Kartli Axemen Tetreres added to garrisons for L3 and L4 Military Ports. 1 line added. From Octavius_5.

H. Units/Custom Battle Permissions Table (Multiplayer)
H1. Principle: Units should be able to play their campaign units in custom battles. Change: Added--Colchis Assault Tetreres, Ardiaei Assault Dieres, Arevaci Assault Raider, Lusitani Assault Raider, Cimmerian Penteres with variants, Parthian Assault Hexeres. Changed--Parthian missile vessels, Egyptian Ballista Five changed to campaign game vessels. 9 lines added, 3 lines changed. From BruceR

Added back in Arverni garrison unit issue, first found by Octavius... all the other L3/L4 Artisan garrisons that were fixed in Patch 16 Data Typos are in the beta now but that one.

Added Vulcanis' observation from the beta forums that Aux Thracians and Aux Tarantines appear to have switched combat values.

Added my own observations that Royal Peltasts should not be the Greek unit with the hoplon that uses the inferior shield wall instead of hoplite wall, and that WoS Light Hoplites should be able to form hoplite wall like their main campaign equivalents can.
