It hasn't, at best since then they've added more ship personalization options in the form of ship skins, and some gamification via events, daily login campaigns, and now seasonal-like content where they promote different activities. The current one started yesterday, you can track down and / or follow NPC haulers (or something like that; the event does not appear in sov null. I moved there a month ago after it seemed like that's where all the fun stuff happens)
