Version 1.7 Update[]

This update was released on the 21st of April 2016. The main focus of this update will be a new starbase system to reduce the amount of micromanagement required.

On the 26th of February dev stream, Boyer explained that the the player would be able to select the modules they wanted added from the list of available modules and constructor would be ordered from a sponsored shipyard/s.

Additional changes included a rework of the ship list in the Ship Designer. How the list of ships is displayed would be changed and better sorting options would be available to make it easier to find and select ships.

On the official forums Wardell stated Stardock's intention that 1.7 would be the last free content update until the release of the standalone expansion ("Crusade") possibly in 2017. While free bug patches would still be done any new content would be delivered as paid DLC.

Wardell stated the reason for this change in direction was:

What I can say, however, is that it is really clear that the free FEATURE based updates aren't creating enough good will to counter the feeling that the DLC does't[sic] provide enough. Therefore, it makes sense to take the budget being used to create new free features and put that into DLC.
