Here's some stuff about Claire which releases today:

"There will be a "day one" patch. It might hit a few hours later after release (Think it's still waiting for QA in EU before we can launch it). The patch just covers bugs we found after we submitted it to Sony. We really want this to go as smooth as possible. I've continuously told him, "No 'No Mans Sky' launch, please". We're confident we got all the game breaking stuff out but, as with any release, there's bound to be an annoying bug we didn't find. With more people playing there's bound to be something that happens that we probably never even would have thought to test. We promise to fix everything you guys find / that we can. It might not happen that same day, as we might wait a week to "round them all up". But it will be addressed. You can always contact me here or on twitter ( @HailstormDavid ) to let me know if you found something. Don't think we're ignoring you or just want to "release a mess then leave" because that's not the case. We started work on our next game already and plan to release more, so we're in it for the long haul. Meaning supporting older titles (Bugs, etc. Not DLC, ew)
That being said, we're pretty confident the patch fixes most issues that we found."
