Saturn Client 0.1.5-beta
StableRelease / build (release) Successful in 4m38sselimaj-dev released this
2026-09-30 20:37:55 +00:00 | 0 commits to master since this releaseSupports Minecraft 1.21.4 – 1.21.11 and 26.1 – 26.3, one jar per version (the 26.1 jar also runs on 26.1.1 and 26.1.2). Requires Fabric Loader 0.19.5 or newer and Fabric API.
Minecraft 26.x
Saturn now runs on 26.1, 26.2 and 26.3, with its menus, mods, emotes and cosmetics. Keybinds you've already set carry over to 26.3, even though it handles keyboard input differently.
Fixes
- Armor Display, Status Effects, SVG icons and the title screen's close button could stop with an error in released builds, and so could Saturn's screens on 1.21.4 and 1.21.5. They now work (#47).
- The emote wheel closes properly after you pick an emote (#48).
Other changes
- Themes saved before 0.1.3 are no longer converted to the newer translucent colors when they load.

Saturn Client 0.1.4-beta
StableRelease / build (release) Successful in 4m36s2026-09-29 16:40:26 +00:00 | 18 commits to master since this releaseSupports Minecraft 1.21.4 – 1.21.11, one jar per version. Requires Fabric Loader 0.19.5 or newer and Fabric API.
New emotes
Eight new emotes on the emote wheel: Twerk, Get the Griddy, Take the L, Dab, Wave, Salute, Shrug and 67. Elbows, knees and the back curve smoothly as they move.
The Front Flip is gone for now, because it didn't play properly.
Cloaks
- Emotes that curve your back, like Twerk and Get the Griddy, hide your cloak until the emote ends, so it doesn't cut through you. Other emotes keep it.
- Choosing None no longer shows a pink and black placeholder cloak.
Menus
- Sidebar: Settings is now second, after Mods, and the HUD editor is last.
- Title screen: the Saturn logo in the dock now opens Saturn's settings, and comes first. Minecraft's options are last. The shift menu is still on its key in game.
Fixes
- Emotes that bend the body (like Get the Griddy) now lean the right way.

Saturn Client 0.1.3-beta
StableRelease / build (release) Successful in 5m26s2026-09-28 21:12:46 +00:00 | 27 commits to master since this releaseSupports Minecraft 1.21.4 – 1.21.11, one jar per version. Requires Fabric Loader 0.19.5 or newer and Fabric API.
Glass
Saturn's menus and widgets are now frosted glass: translucent panels, buttons and the dock blur the game behind them, with rounded edges that match exactly. It works on every supported version.
- Three blurs in Settings › General: World blur for the world or panorama behind Saturn's screens (it fades in as a screen opens), Menu blur for panels, and Widget blur for buttons, the dock and your account chip. Set a blur to 0 to turn it off.
- Real transparency: the Background and Primary colours in UI Style now use their own opacity. Turn it up to 100% for solid panels, or down for more glass. The presets look the same as before.
GUI scale
Three new sliders in Settings › General set how big Saturn's screens are, from 0.5× to 2× of Minecraft's GUI scale: Title screen scale, Menu scale (mods, settings, cosmetics) and HUD menu scale (the emote wheel and the shift menu).
Title screen
- A cleaner layout: the logo with Singleplayer and Multiplayer close under it, your account in the top left, a quit button in the top right, and a subtle version in the bottom left.
- A smaller dock with Mods, Cosmetics, the shift menu (the Saturn logo) and Minecraft's options.
- The intro now plays in reading order, from the top left to the dock.
Fixes
- Hats and cloaks stay on your head and back when you crouch and during emotes (like the backflip), and cloaks lean with your chest when an emote bends your body.
- Colour picker: much faster. It used to draw its colour square one pixel at a time.
- Animations: items no longer show as faint ghosts before they animate in.
Updating
- World blur was called Background blur, so its value resets to 5.
- Default and preset theme colours get their new translucency automatically. Colours you picked yourself keep their opacity; lower it in Settings › UI Style for glass.

Saturn Client 0.1.2-beta
StableRelease / build (release) Successful in 4m34s2026-09-27 17:21:48 +00:00 | 46 commits to master since this releaseSupports Minecraft 1.21.4 – 1.21.11, one jar per version. Requires Fabric Loader 0.19.5 or newer and Fabric API.
A new look
Every Saturn screen has been redesigned: translucent panels over the game, a navigation rail, Lucide icons, and a consistent set of controls.
- Mod menu: search, category filters built from each mod's tags, and cards with an on/off switch and a settings button.
- Mod settings: a header with the mod's details, Reset, and an Enabled switch. Every setting has a one-line description. Settings with a range use sliders, choices use dropdowns, and colour settings open a picker. HUD mods show a live preview.
- Client settings: General, UI Style and Animations sections. UI Style has four theme presets (Saturn, Midnight, Amethyst, Emerald), a colour grid, and corner radius and font settings. Animation settings are grouped per menu, and curve dropdowns preview the easing curve.
- Cosmetics: one screen for cloaks and hats, with your player on the left (drag to turn them around). Click a cosmetic you own to equip it, or claim a new one for free.
- Title screen: your menus in the middle; your player, a dock for Mods, Cosmetics and the HUD editor, and the version along the bottom.
- Emote wheel: emotes with their names, and page controls in the middle. The emote wheel key now closes it too.
- HUD editor: HUDs are drawn as they look in game, with outlines, a visible resize handle, and a hint. They stay on screen, and the world behind isn't blurred.
- Background blur: a new setting (Settings › General) for how much the game behind Saturn's screens is blurred. It now works on 1.21.6 and newer too.
Emotes
- Emotes now run on Saturn's own emote library, with bending limbs, on every supported Minecraft version.
Fixes
- Emote wheel: one emote never showed up and another appeared on two pages, and empty slots could be clicked.
- Nametags: custom nametags work on every version.
- Title screen: Saturn's panorama shows on 1.21.6 and newer.
- 1.21.11: the TPS display and day counter no longer show 0, and resizing the window works on Saturn's screens.
- 1.21.9 and newer: dragging on Saturn's screens works (sliders, the HUD editor).
- 1.21.4 – 1.21.7: role icons in player names show again.
- Scrolling: trackpads and mouse wheels scroll smoothly, and the scrollbar can be dragged.
- Settings: Reset works (it did nothing before), and the HUD "In-Game Display" settings keep their order.

Saturn Client 0.1.1-beta
StableRelease / build (release) Successful in 18m36s2026-09-25 16:37:03 +00:00 | 94 commits to master since this releaseSupports Minecraft 1.21.4 – 1.21.11, one jar per version. Requires Fabric Loader and Fabric API.
⚠️ Update required
Signing in to Saturn has changed. 0.1.0-beta2 and older can no longer connect to the Saturn server, so cosmetics and emotes won't work until you update to this version.
Security
- Your Minecraft access token no longer leaves your computer for Saturn's server. Saturn now signs you in the way vanilla online-mode servers do: your client proves who you are to Mojang, and Saturn's server asks Mojang to confirm it (#7).
New
- Update notices. Before connecting, the client checks which versions the server supports. An outdated but still accepted version shows a warning and connects anyway. An unsupported version shows a warning and doesn't connect.
- Automatic reconnect. If the connection to the Saturn server drops (a network blip or a server update), the client reconnects on its own, retrying every 1 s up to every 60 s. You no longer need to restart Minecraft (#4).
Fixes
- Tab list: server rank prefixes, name colours and team formatting are shown again. They were previously lost for every player, not just Saturn users (#3).
- Performance: players who don't use Saturn are no longer looked up from the server on every frame. That caused constant server traffic and a growing backlog that delayed other players' cosmetics (#2).
- Stability: fixed player and cosmetic data being changed from several threads at once, which could crash the game (#6).
- No more hangs: every request to the server now times out after 10 seconds instead of waiting forever. A stuck request used to stop all other players' cosmetics from loading (#5).
- Smaller download: the title-screen panorama was optimised, so each version's jar is about 45 MB instead of about 120 MB. It also uses much less GPU memory on the title screen.
- The connection library (session-java 0.2.0) no longer loses fast responses, fails concurrent requests, or leaves requests hanging after a disconnect.
Also since 0.1.0-beta2
- Added support for Minecraft 1.21.7, 1.21.8, 1.21.9, 1.21.10 and 1.21.11
