Dwarf Fortress Remote now supports Dwarf Fortress / DFHack version 0.43.05-r1 (64bit version only). This is the first 64bit version of Dwarf Fortress, and it can support bigger worlds without hitting a memory limit, and purportedly a little bit faster in some cases (as well as having a few bugs fixed in the game itself, as usual).
The new version is compatible with saves from older versions so feel free to update (however you need to have a 64bit OS to run this and future versions). The easiest way to update is just to install a new package from mifki.com/df/setup, and copy saves located in
data/saves folder. You can then re-add your server to the application, or copy
data/init/remote.txt file to preserve settings like published name and password.
I've also added an article how to update to a newer version of Dwarf Fortress if you have Remote server running in a Docker container, for example, on a cloud server.
