 ## [2.0.4] - 2022-12-13
 ### Changed
-* Bumped RNSM to 1.1.0: Switched x axis units to seconds instead of frames now that it's available. This means adjusting the sample count to a lower value as well to 30 seconds, since the x axis was moving too slowly. (#788)
 * Updated Boss Room to NGO 1.2.0 (#791).
   * Removed a workaround in our tests waiting for two frames before shutting down a client that is attempting to connect to a server. (see https://github.com/Unity-Technologies/com.unity.netcode.gameobjects/pull/2261)
 * Replaced the workaround using custom messages to send a disconnect reason to clients with the new DisconnectReason feature in NGO. (#790)
