https://github.com/Pulsar4xDevs/Pulsar4x/releases/tag/v0.31-AlphaThis version has missile combat and point defense, which means several new components as well as missiles themselves are designable. Likewise the missile fire control is now functional. On the point defense end turrets, CIWS, and amms can now all be used to shoot down missiles. Turret and missile design may be reached from the turret and missile design buttons on the research project popup, and CIWS, previously added to the research project popup, can now be used to create components. Point defense mode on the F6 individual ship display Combat Settings tab is now functional, and modes may be set for various fire controls. Missiles may also be targetted manually from here. Missiles cannot be the target of any order to move towards them for simplicities sake.
As with the alpha 2 release there are components that are not implemented, but can still be added to ships, these are related to industry and transportation. Secondary stars orbit extremely quickly, the math says thats how it should go. We'll keep an eye on that however.
[edit]
There is also a much improved orders system via Se5a, a way to remove Log4Net logging(hopefully I got everything there), and some other general background improvements and bugfixes.
