A lot of internal changes in this update, with several translation and server improvements. Player-facing changes include better sorting of challenge missions in your Inbox (Events tab), and a huge reduction in the initial weapon cost in the Galactic Store. Oh, and the Easter content has now been removed. And, as usual, many other small bug fixes and quality-of-life improvements.

NOTE: v80.1 has some serious issues – please use v80.2 instead
