When the new version is ready for release. Don't push Gazebo. Although he is releasing new versions faster than we can playtest them, it seems that apart from working on CPP, Gazebo also works at university and has private life

I think he is merging some new stuff from the new WHoward's DLL, which can be very time consuming, so I think even he does not know when it will be ready.
Is there anything particular you are waiting for? It seems the latest 10/23 version is stable and quite balanced. If you are concerned about the herbalist wrong yields, go to the thread about the 10/23 version, I posted how to change the yields in XML files manually, it is very simple.
