Build 1.21.10 with Stonecutter from the shared src/
Step 2 of #8. versions/1.21.10/src is gone; 1.21.10 builds from src/ as
:1.21.10, with versions/1.21.10 keeping only gradle.properties and run/.

API differences go behind version comments: render layers (ShaderUtils),
Camera.update's World vs BlockView (CameraMixin), the text and textured-quad
render states (RenderScopeImpl), Screen.init (SplashOverlayMixin) and
jspecify's @NonNull (SaturnRenderState).

Features 1.21.11 leaves out stay on 1.21.10, with a TODO for 1.21.11:
WorldFeatureImpl.getWorldAge, SaturnScreenFabric.resize and
EntityDrawerImpl clearing the hitbox.

Hats now render on 1.21.10: its HatFeatureRenderer overrode the
render-queue method with an empty body, and the working code sat in an old
VertexConsumerProvider method nothing called. 1.21.10 now uses 1.21.11's
render-queue implementation (HatFeatureRenderer, ObjModel, ObjRenderer),
and also gets 1.21.11's null check on the player's display name.

The 1.21.10 jar has the same entries, fabric.mod.json and mixin configs as
before; only those four classes and ShaderUtils (a helper method for
entityAlpha) have different bytecode. The 1.21.11 jar only differs in
ShaderUtils.

## About
Saturn Client is a free, open-source Minecraft client designed to enhance the gameplay experience while staying lightweight and customizable.
Our goal is to build a clean, optimized client that the community can contribute to and improve together.
Saturn runs on Fabric and supports **Minecraft 1.21.4 to 1.21.11**, with one build per version. If something doesn't work on your version, please open an issue.
## Features
- Free cosmetics that don't require real money: cloaks, including animated ones, and hats
- 18 built-in mods: Armor Display, Auto Sprint, Clock, Coordinates, Crosshair, Day Counter, FPS Display, Freelook, Fullbright, Health Display, Keystrokes, Nametags, No Fog, Ping Display, Speedometer, Status Effects, TPS Display and Zoom
- Clean and modern UI with animations
- Ongoing performance improvements
- Open-source and community-driven
## Installation
1. Install [Fabric Loader](https://fabricmc.net/use/) and [Fabric API](https://modrinth.com/mod/fabric-api) for your Minecraft version.
2. Download the Saturn Client jar for the same version from [Modrinth](https://modrinth.com/mod/saturnclient) or the [releases page](https://git.selimaj.dev/saturnclientmc/saturnclient/releases).
3. Put it in your `mods` folder.
### Network use
For cosmetics, Saturn Client connects to the Saturn server (`saturn-server.selimaj.dev`). You're signed in the same way as on an online-mode Minecraft server: your client proves who you are to Mojang's session server, and the Saturn server asks Mojang to confirm it. **Your Minecraft access token is only ever sent to Mojang, never to the Saturn server.**
## Building from source
The version-independent code lives in the `common` submodule, so clone with submodules:
```sh
git clone --recurse-submodules https://git.selimaj.dev/saturnclientmc/saturnclient.git
cd saturnclient
./gradlew buildAll # every version → build/allJars/
./gradlew :1.21.11:build # a single version (versions not on Stonecutter yet: :mc-1.21.9)
./gradlew :1.21.11:runClient # launch a development client
```
Building needs Java 21.
## Contributing
We welcome contributions of all kinds:
- Code improvements
- Bug fixes
- UI enhancements
- Cosmetic designs
- Suggestions and feedback
If you're an artist or designer interested in helping with cosmetics or visual assets, we'd love to collaborate.
Most features belong in `common`, which every Minecraft version shares. For code that differs between versions, see the [version guide](VERSION_GUIDE.md): it covers how the versions are laid out, porting a change to all of them with `scripts/port.sh`, and adding a new Minecraft version. Every pull request is compiled for all versions automatically.
