I'm using version 0.34 for my current effort, though I don't see why there'd be any problem using this file for any other one. Feel free to add your own translations and re-upload! Still, having the UI translated has really helped me get more into the game.

Truthfully, I only picked-up this game for the first time a couple days ago, so the translation is very much a work in progress.

In case anyone's interested, I've been editing the machine translation by hand and have a copy of my translation file you can download and place in your own installation so some of the text appears in sensible English.
