Java Edition 1.16.4

1.16.4 is an upcoming minor update to Java Edition with no set release date, which will add the social interactions screen and fix two bugs.

Additions

 * General
 * Added Social interactions screen.
 * Gives players the ability to disable chatting with certain players, thus hiding any messages receiving from them.
 * Opens with a configurable key binding, by default.
 * Whether a player is hidden resets when re-joining a server.

Changes

 * Technical
 * New network protocol scheme, with a high bit (bit 30) set for snapshots. The protocol version will increase by 1 for each snapshot, but full releases may keep the same protocol version as the previous full release in cases where the network protocols are compatible.
 * More information is now added to the crash log in cases where poor performance causes the server to crash.
