Sorry to hijack this thread to ask - but what is the current state of sliding sync? Does it still require a separate proxy service to enable sliding sync if you're self-hosting a homeserver; or is it upstreamed into synapse? Also is there a list of clients that are sliding sync aware?
Not that many clients have actually adopted it though, because the MSC is still not 100% finalised - it's currently entering the final review stages at last now over at https://github.com/matrix-org/matrix-spec-proposals/pull/418.... Right now Element X uses it (exclusively), and Element Web has experimental support for it; I'm not sure if any others actually use it yet.
Good to know! These are very important features and not having them really gets in the way of switching off of classic. I am worried about "intial" support - what is going to break with threads and spaces that I try to join with thr new Element X?
