Looks like it's close to a 9GB update for those who had the latest 4.9 downloaded already.

Anyone here jumped in yet?

How's it running?

I jumped in already. It was actually running far better than I was expecting. I went straight to Siege of Orison (a quick solo run). Enemies were very reactive and deadly if I wasn't cautious.

Performance-wise the FPS seemed better.

Inventory worked better than 4.9 as well, I could drag attachments to weapons from the main inventory view without issues. The only issue here was, at one point, with putting some tea into my hand to drink. Either right clicking and "carry" worked or just dragging it to my hand worked, so it was only a momentary hiccup for a few seconds.

Ships spawned fine for me, I didn't notice anyone in chat complaining about any major issues (but I wasn't paying too much attention once I jumped into Siege).
