# Protocol version

The Minecraft protocol uses a version number to distinguish between different
protocol versions. Each new Minecraft version having a change in its protocol
gets a new protocol version.

## List of versions

- https://wiki.vg/Protocol_version_numbers#Versions_after_the_Netty_rewrite

## Configuration

In `lazymc` you may configure what protocol version to use:

[`lazymc.toml`](../res/lazymc.toml):

```bash
# -- snip --

[public]
# Server version & protocol hint.
# Sent to clients until actual server version is known.
# See: https://git.io/J1Fvx
version = "1.17.1"
protocol = 756

# -- snip --
```

It is highly recommended to set these to match that of your server version to
allow the best compatibility with clients.

- Set `public.protocol` to the number matching that of your server version
  (see [this](#list-of-versions) list)
- Set `public.version` to any string you like. Shows up in read in clients that
  have an incompatibel protocol version number

These are used as hint. `lazymc` will automatically use the protocol version of
your Minecraft server once it has started at least once.
