Latest devlog said 2 nuggets and angry treeclimbers, so I guess around Dec 1st.
I still stick to my 16th of november statement which seems to be pretty close to the work quota unless a spanner gets thrown into the works, im sort of skeptical on how nessecary your party members speaking on your behalf with 'witty retorts' is (as one of the nuggets) when infiltrating & tresspassing with intent to steal since i think there will probably be a lot of dummy or null responses if your party member can't think of a relevant lie or exception.
Hair creatures being too tiny & unkillable are also going to be bugfixed, not sure what that entails as the 'fix' but hopefully it'll fix the uses & combat of creatures that are extremely small, kittens for instance being a not quite undead example.
Here's the devlog from my phone
New Blog Update: (Toady One) Down to two now! The various remaining artifact issues were uneventful. now the main thing left to do is handling all this companions-during-infiltration business, the issue being that a goblin might address one of your companions instead of you , due to line of sight etc... and your buddy needs to be able to pipe up intelligently to save all your lives. might take some days to the various various ways it can All Go Wrong. Then finally some bugs i promised to do before the release. Normally we do bug fixing for a while afterward (and of course we'll still do that) but e.g dwarves being stuck in trees and broken undead tissues managed to get to the pre-release promise list,, in some discussion or other. So we'll see how that goes after the companion identity stuff is handled. Then we should be ready!
Apologies about the poor formatting, it was submitted about 6 hours ago and the bay12 site hasn't been updated yet with the respective changes, im sure on the site it would be more neater.
