I was asked what the freighter changes actually entail, since "Various freighter rebalances including powercore changes" (from patch notes) doesn't actually tell you much.
Hull and Hold should be self-explanatory, BB is nanobots and shield batteries, Max Turn is the maximum turn rate in degrees per second, Time to 90 is the time it takes to achieve 90% of that after initiating the turn, aka responsiveness.
I will put bug notes or planned changes in Karst pink.

*The Ragnar is now more of a light transport hybrid than a freighter. It thrusts at 174 and mounts a transport shield. The engines will not be working at the moment for existing ships, this should be fixed soon.
There are now three types of powercore, small, medium, large.
Small is 1200/30000, Medium 1400/34000, Large 1650/38400.
As a general change, all freighters should be able to mount fighter auxiliary weapons in their CD slot.
Minor arc adjustments not mentioned here were also made.
The process that led to these changes was to test the ability of a freighter to evade fire, their most important trait, to determine survivability and speed buffs, and their purpose for determining powercore. Mining-capable freighters have been buffed relatively less. Unlawful freighters have been buffed relatively more.
You'll notice that almost all freighters except those that performed exceptionally well in testing were buffed in one way or another.
This is intentional to make them more viable for roles other than self-defense, which they are currently rarely used for.
I encourage you to test freighters in various roles, and post questions, bugs, and suggestions here.
