Mostly just one important fix, otherwise relevant for ViaBackwards

1.21.5 client support

• Fixed custom model data handling in block entities in 1.21.2->1.21.4
• Fixed removed item data components in item hover events in 1.21->1.21.2 and 1.21.2->1.21.4

• Fixes to item hover event handling in 1.20.3->1.20.5 (by kennytv, EnZaXD)
• Fixed duplicate registry entries causing errors (by EnZaXD)

• Fixed error with 1.9+ clients joining a 1.8 server when ViaVersion installed on Velocity (by EnZaXD)
• Removed consumable blocking sound for 1.21.4 clients on 1.8 servers (by lowercasebtw)

This version also adds custom payload sending to get player protocol version data across platforms (by EnZaXD). If ViaVersion is installed on a proxy (e.g. Velocity or ViaProxy) or the client (e.g. ViaFabricPlus), you may be able to get this information by listening to custom payloads ("plugin messages") on any platform within the chain, which can be useful for anti-cheats and other player version-dependent code. See the wiki for more information. Example JSON data:

{
  "platformName": "Velocity",
  "platformVersion": "3.1.2",
  "version": 760,
  "versionName": "1.19.4"
}

Please also note that at some point in the future, ViaVersion will require at least Java 21 to run. If you're already on 17, an update should be trivial.
