Will be there an update to the most recent version (currently 1.1.5). I see 32/36 unlocks but I dunno what are the remaining 4.[sound F/X: source diving]
Well, first off, the addon has no effect on the numbers displayed in the title of the character creation dialog; those reflect things you've actually unlocked, and as the description says, this addon doesn't unlock anything, it just ignores some of the locks. More generally, any new locked races or classes will almost certainly use the same birth-descriptor locking mechanism as the current unlocked races and classes,? so they should get picked up by the addon automatically without further modification.
As for what unlocks you may be missing... [sound F/X: further source diving]
let's see, the current counted locks are 18 classes, 3 races, 5 talent trees, 2 birth options, 2 difficulty levels, 2 campaigns, 2 cosmetic effects and an Alchemist class feature. (Hmm, that only adds up to 35. Dunno what the 36th one might be; maybe something Steam-specific?)
? Except for donator/buyable classes like Stone Warden, which use a different mechanism that this addon couldn't influence even if I wanted it to.
