# ViaBackwards<\/p>\n
**On Fabric, use either ViaFabric or ViaFabricPlus. To override the included version**
\n– in **ViaFabric**, put ViaBackwards into the `mods` folder
\n– in **ViaFabricPlus**, put ViaBackwards into the `ViaFabricPlus\/jars` folder<\/p>\n
**Depending on the platform and version, this also requires ViaVersion.**<\/p>\n
Requires Java 17. See here how to update your installed Java version. As a last resort, you can download Java 8 downgraded builds from our ci.<\/p>\n
## Get access to Via* with new MC version support early
\n**Starting with 1.20.5, ViaVersion and ViaBackwards will only be released a day or so *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**:
\n– GitHub Sponsors (*preferred option, also comes with source code access*. Use the `\/verify` command on this Discord after), or alternatively
\n– Patreon (see the highest tier and make sure to link Patreon to your Discord account under Discord Settings->Connections)<\/p>\n
## Note on release channels
\nIt is recommended to always use the latest beta release. Alpha builds are used for work on snapshot version compatibility or other cutting-edge changes.<\/p>\n
**Always use the same build channel across the ViaVersion, ViaBackwards, and ViaRewind projects.**<\/p>\n
