**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
- Fixed shulker boxes content not being visible in 1.20.3->1.20.5 (by EnZaXD)
- 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 blocks in minecarts in 1.8->1.9 (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)
- Note: Item desyncs may occur if you are running a version between 1.17 and 1.21 or don't have ViaVersion running on an up-to-date Paper server
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](https://github.com/ViaVersion/ViaVersion/wiki/Player-Details-Protocol) for more information. Example JSON data:
```json
{
"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.**
