The main change is that we are removing Develop branch from the game. There will be only one branch and updates will be tagged as Minor or Major. We will still patch the game every week with Minor updates, but Major updates will not be scheduled with strict dates in advance but rather will be released only when everything is completely tested, fixed and approved by a closed testing group to ensure the build is ok. Also we will leave the previous update as a separate rollback branch on steam - so you can always switch one update back.
This week’s update contains more improvements to multiplayer, performance and the overall game as well as a new multiplayer dogfighting scenario. We’ve also implemented turret and thruster parallelization which will significantly improve performance on grids using lots of them. And there’s a new multiplayer scenario being released this week called Dead Drop Arena.
