we have just released Factorio 0.3.0 !
We took quite some time and put a our effort into this release. There is a lot of internal refactoring and preparations which won't be visible to the player but they will make our live a lot easier in the future. We are "tying our laces before setting for a run".
Apart from that we have put quite some effort into improving modding capabilities. Uptil now making and using mods was just for the hardcore fans of the game. We really see the importance of good modding system so we started building one. The mods are now standalone packages and allow for much easier and cleaner combination. Together with modding improvements we updated our Lua scripting API based on the feedback gathered from our forums.
Apart from code changes there is some new graphics in the game. Our graphic Albert has spent more than two weeks here in the Prague. That allowed us to get a lot of work done. There are new inserters, turrets, walls, etc. Even though these all pieces are new graphic they might not be the final version. At the moment Albert is working on a high level artistic direction for the game. That might look like quite late (with the game already in the alpha). But better late than never :).
The release is marked as experimental. This means that in order to download it you need to click the "experimental" link on our download page next to the "Download" title. After the release gets tested and no serious bugs are reported it will be marked as stable.
