Normally when the game is updated, they may or not add more content or just apply fixes for some events or stuff that may happen or not... for example, Branded Azel v1.00 had a problem where a event scene wasn't triggered and game crashed when attempt to start event instead of just error window and skip, then developers released patch later that doesn't add any content but fix the behaviour showing the event correctly later... so. Basically, if this game didn't had any add-on or whatever through the time it was developed, the translation will just fix minor errors such as text out of place, event not triggering and so(since it uses the actual files of v1.06, the max we may meet, is an attempt to start an event that doens't exist on the game v1.02 that was added later... "IF", however for these games, they hardly add content, and when they do, they made an add-on chapter such as Branded Aizel prequel chapter with a brothel mode). What i hardly doubt will be the case... probably this last patch were script fix/game behaviour fix... that was automatically implemented in translation files anyway(without changes to the game itself at all).
