It was a long way, but the 0.4.0 version is finally finished. It took almost 9 months in order to close all issues in the milestone. The two most time-consuming issues were atmos rework and new serialization system. During the development internet stranges have started to show some interest in the project and have made various pull requests. Special thanks to shelltitan who almost single-handedly has made all new gameplay features.
Full changelog can be found here.
The v0.4.0 beta-test will be conducted and the results will determine the path of the further development. If network will work correctly then it will be considered to make the v0.5.0 milestone more gameplay oriented. However, it is important to continue improving the game engine because in long term it is more efficient. So the v0.5.0 milestone planning is a separate hard task, and it will be done later.
