Hello,
You need to click on your patronage icon, on your character portrait to see your runes.
Your ship should be in the Astral Hangar, at the Astral Academy. There's a new teleport plateform at the port of your capital, that leads to the Astral Academy, and then, it's the same as before, you go to the hangar, and summon your ship.
Ask for someone in game to explain how to get there
