Supported Versions

As a plugin, ViaBackwards runs on servers on releases 1.10-latest. You can also use ViaBackwards in ViaFabric or ViaFabricPlus.

- in **ViaFabricPlus**, put ViaBackwards into the `ViaFabricPlus/jars` folder
See [HERE](https://viaversion.com) for an overview of the different Via* projects.
Snapshot support
--------
**ViaBackwards will only be released a few days *after* a Minecraft update** unless the protocol changes of the update were trivial. If you want early-access, usually days or even weeks before the final release, you can subscribe to either:
- [GitHub Sponsors](https://github.com/sponsors/kennytv/sponsorships?sponsor=kennytv&tier_id=385613&preview=false) (preferred option. Use the `/verify` command on this Discord after), or alternatively
- [Patreon](https://www.patreon.com/kennytv/membership) (see the highest tier and make sure to link Patreon to your Discord account under Settings->Connections)
This also includes access to a private repository with the code, which will be pushed to the public repository after the given delay on a Minecraft update.

Known issues
-
* 1.17+ min_y and height world values that are not 0/256 **are not supported**. Clients older than
1.17 will not be able to see or interact with blocks below y=0 and above y=255
* <1.17 clients on 1.17+ servers might experience inventory desyncs on certain inventory click actions
* Sound mappings are incomplete ([see here](https://github.com/ViaVersion/ViaBackwards/issues/326))
* <1.19.4 clients on 1.20+ servers won't be able to use the smithing table. This can be fixed by
installing [AxSmithing](https://github.com/ViaVersionAddons/AxSmithing)
