base on Allows of newer clients to connect to older server versions for Minecraft servers. # ViaVersion [](https://viaversion.com) [](https://github.com/ViaVersion/ViaVersion/actions) [](https://viaversion.com/discord) **Allows the connection of higher client versions to lower server versions - it works on any platform you can think of.** The base ViaVersion jar runs on Paper and Velocity. We also have projects integrating ViaVersion to run on Fabric, Forge, Sponge, or as a standalone proxy to join from basically any client version on any server version from the past decade. **See [HERE](https://viaversion.com) for an overview of the different Via\* projects.** Note that ViaVersion will be able to **run best on either Paper servers or through [ViaFabricPlus](https://github.com/ViaVersion/ViaFabricPlus?tab=readme-ov-file#viafabricplus)** due to having direct access to client/server state and more extensive API. Supported Versions:  **User Docs:** https://docs.viaversion.com Snapshot support -------- **ViaVersion 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. Releases/Dev Builds -------- You can find official releases in the following places: - **Hangar (for our plugins)**: https://hangar.papermc.io/ViaVersion/ViaVersion - **Modrinth (for our mods)**: https://modrinth.com/mod/viaversion - **GitHub**: https://github.com/ViaVersion/ViaVersion/releases Dev builds for **all** of our projects are on our Jenkins server: - **Jenkins**: https://ci.viaversion.com ViaVersion as a Dependency ---------- **JavaDocs:** https://jd.viaversion.com **Maven:** ```xml <repository> <id>viaversion-repo</id> <url>https://repo.viaversion.com</url> </repository> ``` ```xml <dependency> <groupId>com.viaversion</groupId> <artifactId>viaversion-api</artifactId> <version>[5.0.0,6.0.0)</version> <scope>provided</scope> </dependency> ``` **Gradle:** ```kotlin repositories { maven("https://repo.viaversion.com") } dependencies { compileOnly("com.viaversion:viaversion-api:VERSION") // Replace the version } ``` If you need access to the existing protocol or platform implementations, use the parent artifact `viaversion`.
