In update 0.8.2 the Arsenal will receive new functionality and a new name - Armory.
We've also decided to add about 50 premium ships to it, that will be available for purchase for doubloons. This will increase the value of doubloons, as many of you have been requesting.
We also removed some of the premium ships from the tech tree to focus it on the researchable ships. Later on we're planning to extend the selection so that you always have an extensive selection of ships to purchase for doubloons.
