From 463c19ac3648b242c480e299349d2ef90bf38a0b Mon Sep 17 00:00:00 2001 From: Sean Quah <8349537+squahtx@users.noreply.github.com> Date: Tue, 14 Feb 2023 12:32:19 +0000 Subject: Faster joins: Omit device list updates from partial state rooms in /sync (#15069) ...when lazy loading of members is not enabled. It's weird to notify a client that another user's device list has changed when the client doesn't think that they share a room. Note that when a room is un-partial stated, device list updates are emitted for every member in that room over /sync.
