they unlock at certain milestone (I couldn't remember when exactly). For Dangers in the dark the next pack is from Mining, I think it unlocks around 145m, and for Feeding the World the pack is from Horde, after zone 75 iirc.
Np :D also the patreon page is updated with more sneak peak every few days.I'm hoping this will be a big one!
Tendsty mentioned on discord that he want to take it slow with next update (hence the 1.4 debuff to some parts of the game)
Apparently people can easily read what's changed next update, to avoid that he's working on secret instead
it is helpful when you just prestiged and want to climb zones faster, you can turn it off whenever you want
