Been away for a while. Any major changes?

Hiya. I used to play this game all the time, but after Grey Havens took over and the release of the new Vanguard missions I started to phase out of it. Have any major changes happened (e.g. quests, floors, drop rates)? Do we have any news on any upcoming updates? Has Grey Havens been more responsive than Three Rings?
The patch notes are sadly sparse as always so they're not much help.
I loved this game and I'd hate it see it disappear.

Have any major changes happened (e.g. quests, floors, drop rates)?
No, the new missions are all just novelties with the last one been better for rads farming than vanaduke. Time wise.
Do we have any news on any upcoming updates?
The dev's lips are more tightly shut than the core's entrance, so no.
Has Grey Havens been more responsive than Three Rings?
They are made from the remnant of OOO, so I will give you one guess as to how responsive they are.
I hate you, because you are a incorrigible pessimist. However, as time goes on, I began to feel you(at least that's what I believe). SK was once my most beloved game of all time, because of the fresh content(2012) and *great* community. Yet the staff never failed to disappoint us, this game is truly dreadful. I love SK but it hurts every time I think of how dead this game is rn,

Well kid,if there is one thing remains constant in this world is that it is far better being a surprised pessimist than a disappointed optimist.
OOO has many screw ups, instead of trying to make up for it. They decided to go full radio silence instead. Shutting themselves away and this disconnection have clearly hurt them in the long run since they stopped giving their player base what they want.
If you think I am incorrigible pessimist, bear in mind, I will be the first to come to OOO's defense if it changes its ways. It is just that at the current scene of SK, I don't see any reason in cutting OOO any slacks. They brought this entirely onto themselves, I am just here to tell it as it is.
And if I hate this game so much, why would I go out of my way and make SO MANY FAN ART FOR IT? What people here tend to forget is that I WAS once just as passionate about this game as anyone else, if not more. They simply don't want to admit the fact that they are just one more day of radio silence away, from becoming like me.
No, I believe its the opposite. Like, there is a saying, the more you love the more you hate. I never doubted your love in this game, because that's what I feel as well. I understand you. TBH I don't hate you anymore now, how did it all begin? I saw a hopeless pessimist on forum spreading cancer, at that moment I think, what a degenerate. However, I see your name so often in the Treasure Vault subforum. I was like, what is this guy doing? Out of curiosity I clicked into it and I am surprised of how many fanfic and arts you've participated in. This changed my thinking entirely. I know that you'll be one of the happiest ones if the game is every majorly updated or a revival occurs. We both are so drawn to the amazing community of this game, and its unique playstyle. This is a magnificent game, the scenarios in clockwork looks amazing. Just think about it, this is a game that hasn't changed since 2012. This indeed shows how great this game once was.
Please don't call me a kid pls;( (I'm 16) ehh and sorry for my bad english

Oh, well that's a little disappointing. I was hoping that since they bought the IP back they were willing to do something substantial with it.
I get that it's like, what, less than 20 people managing 5 games at once? But I was really hoping we would get more communication from the devs. Like I just wanna know if anything is even being worked on at all. There's really no need for the silence.
Thanks for the answers anyway guys.

It's a bit outdated, but you can check out the State of Haven thread. There has been interactions (a big one was Gyre-Of-Guile, if i'm writing that right, who actively worked with various players on the forums to solve an issue with the Steam Mac client), however it seems they like to stick to their silence and let the game talk for itself, which is all fair but you have certain people wanting more interactions. Luckily, the Game Masters have popped up more often, but as of late we haven't had any of Hera's fun little parties.
I suspect we will get one soon though, since the spooky october season is upon us.
Knights, you know I like this game, too, & GH has been doing all they can to keep it going, & still are to this day. We've still been doing adventures, & would be amazed to see more new adventures, though, I know that takes time to make them. Long as we keep supporting them, they'll keep brining new things in.

Yeah, the State of Haven thread is a bit outdated, but I'm sure we might see a more dated thread soon, since it's been 1 year on that.
You are right that the patch notes (on the wiki at Release/all) are not updated anymore and hence sparse. For recent changes, instead read the Announcements forum.
The only big change, since the rank missions you mentioned, has been the sleep update, with new monsters, equipment, and levels:

Grey Havens has been more responsive than late Three Rings, but less responsive than early Three Rings. They have their hearts in the right place, but their resources are very limited. So you should not expect lots of new content.
All online games gradually diminish until they are shut down. I've been hearing about the disappearance of Spiral Knights since 2011, and it's still here. My recommendation is that you enjoy it for what it is (if you do enjoy it) while you can. Cheers.
