ViaVersion

Our aim is to allow newer client versions to connect to older server versions. Just drag and drop it into the plugin folder and you're done, see below if you use a proxy like Velocity. We currently support Paper and Velocity - there are also addons for BungeeCord and Sponge.

Java 17 requirement

• See https://docs.papermc.io/misc/java-install on how to update your Java version
• Even Minecraft 1.8 is mostly able to run on Java 17, although for a better experience you should use a fork that fixes smaller issues
• Some older versions require the Paper.IgnoreJavaVersion system property to be set (-DPaper.IgnoreJavaVersion=true as a startup flag), but run perfectly fine using Java 17
• If all else fails, use the Java 8 compatibility builds we provide at risk of not receiving support for issues it could cause - you should not make yourself depend on these too much, they will generally only be updated on releases

We suggest reading our Installation page on our docs first, this will ensure everything is set up correctly.

Here's what is supported (Newer versions on older servers):

Note: ViaVersion only supports newer versions, even on subversions! Use ViaBackwards and ViaRewind to allow older versions to connect. Builds labelled with a dash (eg. -DEV) are on our build server. If you're confused what Via* plugins you need click here.

Do you use BungeeCord / Velocity? Ensure you have updated it first, you can use the plugin on all your backend servers OR BungeeCord/Velocity. Compatibility is the best when on your backend servers.

Kicked for too many packets? We include a packet limiter if you need to disable this simply set the limits to -1 in the config.

• All plugins you use should be made for the Bukkit version you are using.
• Reloads are buggy, don't report bugs if they break your server, just reboot.
• Make sure your BungeeCord / Velocity plugins are up to date & so is Bungee / Velocity. (Also try removing SkinRestorer if disconnect issues if you use it)
• BKCommonLib does not work properly with ProtocolLib for 1.8.8, you can use my special version here.
• Orebfuscator does not work properly with ProtocolLib for 1.8, you can use my special version here.

We love people supporting us, and it takes a huge amount of work to do what we do, consider becoming a sponsor and get access to early releases here.

How do I use this with BungeeCord? I'm getting outdated server issues? Have you checked you've updated BungeeCord

Can I use 1.7? We don't plan on supporting it due to the work involved. Use ProtocolSupport with ViaVersion on 1.8 server, though we don't have copies of these (Build 388). Or preferably, ViaRewind + ViaBackwards.

My blocks look weird / don't connect? Enable serverside-blockconnections: true in the config.

Will you update to version 1.x? We plan to update as new Minecraft updates come out, yes.

I can't use an item, block, feature from a newer version?! We aim to allow compatibility, we don't intend to add new items, blocks.

Are you open source? https://github.com/ViaVersion/ViaVersion

Can I donate to you? Sure, https://viaversion.com/donate:)

I get a weird disconnect error? Try with no plugins, if it still persists report it to us. Otherwise, there is another plugin conflicting, remove plugins until it stops.

My players get kicked for sending too many packets? If you use resource packs / have really laggy players it's suggested to increase max-pps in the config. (Try doubling it until your players don't have issues, it's there to prevent spam exploits)

I need help! See the section below, preferably join our discord.

What do all the config options mean? You can read our docs here.

What are the commands?

• /viaver list - Show what players are on what versions
• /viaver autoteam - Toggle collision auto teaming, you may need to disable if you are getting bungee team issues.
• /viaver dontbugme - Toggle the update notifier
• /viaver pps - Show the packets per seconds for ported players.
• /viaver debug - Useful for packet crashes and reporting, will show all packets on the console. Don't used unless asked to.

(Use viaversion.admin for perms)
