SSUI v5.13.2 🐞

Minor improvements and fixes:

SLP: Reinstall without losing mods

• Added a Reinstall SLP button in the SLP management panel

• Reinstall removes only the SLP plugin directory, preserving all installed mods and modconfig.xml, then downloads and installs the latest SLP version

• Available via POST /api/v2/slp/reinstall and UI -> config -> SLP

• Added 🎮 Game Version button to the server status panel - shows the detected game version as an ephemeral message (button only appears once a version is detected)

• Added 🔄 Next Auto Restart button -shows the next scheduled restart time in the user's local timezone using Discord's native timestamp formatting, including a live countdown (button only appears when auto-restart is enabled)
  Auto-restart schedule now tracks the next restart time at runtime; the value is cleared when the server stops or auto-restart is cancelled

Bug Fix: Detached Game Server on SSUI Update/Restart ( Fixes #159)

• Applying an SSUI update while the game server was running caused the server process to become detached — SSUI would lose track of it and start a second instance on the next "Start Server" command
• SSUI now gracefully stops the game server before launching the new executable, on both Windows and Linux
• Same fix applies to RestartMySelf() used during the post-update self-restart

What's Changed

• v5.13.2 - SLP fix and discord improvements by @JacksonTheMaster in #161

Full Changelog: v5.13.1...v5.13.2

SSUI v5.13.1 🔧 Remote Galaxy

This release features refactors of the Discord integration, adds THEMES to the UI, redesigns the connected players panel with rich embeds, adds server uptime display on the WebUI, improves backup retention logic, upgrades SSUI to Go 1.26, and brings SSUICLI quality-of-life improvements along with a couple more improvements, read below:

🤖 Discord Improvements

Refactor of the Discord Integration

Tip

The good news: Functionality will not be disrupted by below changes, and you don't need to reconfigure anything.
The config package migrates old keys to new keys.

Caution

The SavesChannel and ErrorChannel where Deprecated.
Those events are now sent to the StatusChannel, which is now called EventLogChannel.

Caution

The ConnectionListChannel and ServerInfoPanelChannel have been combined into a unified StatusPanelChannel.

Note

The configured ConnectionListChannel will be migrated and reused as the StatusPanelChannel
The configured StatusChannel will be migrated and reused as the EventLogChannel
The configured ServerInfoPanelChannel is now unused in favor of the unified StatusPanelChannel
You can safely delete the now unused channels SavesChannel, ErrorChannel and ServerInfoPanelChannel from your Discord.

• Deprecated dedicated saves channel in favor of evens channel and Consolidated server info and connected players panels into a single status panel, sendServerStatusPanel, which now handles player connection updates and server info / password gathering.

Connected Players Panel Redesign

The connected players panel has been completely redesigned — gone is the plain-text code block, replaced with a rich Discord embed:

• Player names are now clickable links to their Steam profiles
• Color-coded: panel green when players are online, grey when empty
• Shows player count and a "Last updated" timestamp

Fixes and improvements:

• Fixed a bug where Discord button interactions (e.g., on the server info panel) were prematurely acknowledged due to a combined condition in the slash command handler. The handler now correctly separates interaction type checks, preventing button presses from being swallowed silently.
• Updated localization keys on UI for Discord channels to be more informative
• fixed the "Error sending log to Discord; Message cannot be empty" bug

🌐 WebUI:

Implement a theme engine for user-customizable themes

This builds upon the theming preparations already done with the xmas update:

• Added a new theme editor UI to the config page for customizing theme colors and presets.
• Added functionality for importing and exporting themes in JSON format.
• Created some preset themes (reused the themes from SSUI v7/SteamServerUI)

⏱️ Uptime on WebUI

Server uptime is now displayed directly on the web UI dashboard next to the status indicator. The /v2/server/status API response now includes an uptime field with a human-readable format (e.g., 1d2h3m4s).

💾 Backup Retention System Improvements

Enhanced the backup retention logic for more accurate and reliable cleanup:

• Fixed a bug where backups from different months but the same day-of-month (e.g., Jan 15 and Feb 15) were incorrectly treated as the "same day" — now uses full calendar day comparison (year + day-of-year)
• The "keep last N" backups now properly update daily/weekly/monthly retention trackers, preventing redundant keeps
• Corrupt or unreadable backup files are now logged and skipped instead of causing the entire backup scan to fail

🖥️ SSUICLI Improvements

• All commands now have descriptions shown in help output
• Commands are split into user and dev categories — run help dev to see developer commands if necessary.
• Help output is now cleanly formatted with aligned columns and color coding
• New dev commands:
  • dumpheapprofile — dump a pprof heap profile for debugging
  • testserverstatuspaneldiscord — sends a fake player list to test the Discord connected players panel

🪲 Bug Fixes & Minor Improvements

• Fixed typo in admin password info text ("Leavy" → "Leave")
• Enhanced "Save Name" config UI label in all localizations to reflect "creates a new save" for less experienced / new users and clarify that changing the value to a non-existent folder name creates a new save

Note

Development focus will fully shift to SteamServerUI by the end of February. SSUI will be updated & fixed for the foreseeable future, but this will likely be one of the last StationeersServerUI feature releases unless @JacksonTheMaster cannot stop working on this (happend twice now, who knows)

What's Changed

• Fix Discord button interaction issues and Improve "Save Name" input labels by @JacksonTheMaster in #152
• Enhance retention logic and backup file error handling by @JacksonTheMaster in #154
• Add uptime information to WebUI by @JacksonTheMaster in #153
• Update Go version and enhance CLI commands by @JacksonTheMaster in #155
• feat: Implement theme editor and engine for user-customizable themes by @JacksonTheMaster in #158
• Discord Integration Refactor, Theming & backup retention improvements, uptime reporting on webUI, Go 1.26 upgrade, SSUICLI improvements by @JacksonTheMaster in #157

Full Changelog: v5.12.3...v5.13.1

SSUI v5.12.3 🎛️ Command Central

This release introduces an interactive CLI dashboard, a new optional Discord server info panel, optional automatic password rotation, and backup download functionality for both the web UI and from Discord.

Note

The Interactive CLI Dashboard is a new experimental feature using bubbletea. It provides a terminal-based UI for server management. Run dashboard or d from your good old SSUICLI to try it out.

🖥️ Interactive CLI Dashboard

A brand new terminal-based dashboard for managing your server directly from the CLI, powered by bubbletea.

• Real-time status, player list, config and SSUI log panels
• Keyboard shortcuts for quick actions
• Server uptime tracking (not yet on UI, sorry NAM)

The CLI Dashboard can be set to launch automatically when SSUI is started in the foreground (is a tty) by setting "IsCLIDashboardEnabled": true in the UIMod/config/config.json. Might become the default at a later stage, let's see.

🤖 Discord Server Info Panel

New interactive Discord panel with a button to get the current server password. Disabled by default, optional when using Discord integration.

Nice for community servers using the new feature below

🔐 Automatic Password Rotation

Keep your server password changing on every restart with automatic password changes. Disabled by default.

• Generates a random 6-digit (numbers from 100000-999999) password on server start
• Configurable via the Discord Settings config tab

💾 Backup Download Functionality

Download backups directly, especially useful for Docker users:

• New download buttons in the web UI backup controls

• /download Discord command to upload backup files directly to Discord

• Buttons on Discord bot /list responses if the list includes 5 or less backups

⚙️ Expert Settings

New "Expert Settings" section in the advanced settings config page for very advanced configuration options.

🪲 Bug Fixes & Improvements

• Increased buffer size for global console channel, fixing missing parts of startup messages during first-time setup. Might lead to the known windows console buffer issues reappearing, let's see.
• Added back to dashboard button to sliding tabs on config page

• Improved config page headline texts
• Docker nightly builds now include -nightly suffix in package name

🌍 Localization

• Added localization for Expert Settings, Server Info Panel, and Password Rotation across de-DE, en-US, and sv-SE

Full Changelog: v5.11.1...v5.12.3

SSUI v5.11.1 💫 Station Modifications

This release introduces functions for installing and uninstalling SLP, along with a comprehensive mod package upload system.
It also adds the multiplayersafe branch to the setup wizard.

Note

The SLP integration is now in BETA. You can access it from the config tab with the SLP Icon, but there will be a Beta disclaimer banner.

This release adds Mod management to SSUI. You can now download & install SLP, upload mod packages and update Mods from the UI with the click of a button.

You can also view installed mods.

Enhance the UI for managing mods
Updated the API to handle mods and workshop details
Add functionality for workshop mod updates
Slighly refactored the CLI for improved structure
Add new commands for testing and managing mods
Improve credits page and add donors Stealthbob & Sumisukyo

This release was initially released as 5.11.0 and was now updated to ship v5.11.1 since 5.11.0 contained a major bug.

• fix terrain system bool incorrectly switching to false for multiplayersafe branch in applyConfig function
• removed SSCM "Save" trigger when detecting an autosave since it constantly double-saves without much benefit beyond that.

• Add Stationeers Launch Pad (SLP) mod management features by @JacksonTheMaster in #148
  Full Changelog: v5.10.1...v5.11.0

SSUI v5.10.1 🐞

This is a very small patch fixing 2 bugs:

• The BackendEndpointPort flag (-p) would not apply if set to 8443
• The WorldID field would not apply if used on the Terrain Settings config page -> removed it from the Basic Settings, now WorldID is to be set from the wizard or the Terrain Settings page
• Added a -GamePort flag to set the connection port for gameserver connections from CLI directly at startup
  • This was added for BadDucky52's SSUI pterodactyl egg to work as intended
  • This means you can now run SSUI inside pterodactyl -> if you have to 🤷‍♂️

In the next days / weeks, a mod support update (v5.11.0) will follow, adding

• StationeersLaunchPad install & uninstall
• SLP ModPackage Uploads
• Possibly automatic mod updates

• Fix BackendEndpointPort not applying if p = 8443, add GamePort flag (ptero) by @JacksonTheMaster in #147

Full Changelog: v5.10.0...v5.10.1

SSUI v5.9.1 - Singularity Escape 🌌✨

Huge thanks to @akirilov (Mens_Rea (Discord)) for the work on this update.

Important

This release is strongly recommended for all users, especially anyone who experienced extremely slow backup loading times or uses ZFS/large backup directories. The performance improvement is night-and-day.

Caution

With this update, the Backup manager no longer supports the old (pre-terrain update) terrain and save system. Please switch to the new Terrain system if you wish to continue to use new SSUI features. Alternatively, you can continue to use the old system by using SSUI 5.8 and below, disabling auto-updates via the config.json file.

New Features

• Added RoundRobin and CommunityStart world configuration options
• Game server console output can now be automatically logged to file (SSUI/logs/gameserver/) (enable from Advanced options)
• Log directory is now created reliably on first start
• added dynamic announcement section to UI with support for fetching and displaying dynamic announcements from external JSON source (github pages) to be able to notify users on the dashboard without the need to update the executable (Update / bug announcements)
• added credits page and credits button and bottom of main dashboard

Major Performance & Stability Fix regarding the Backup Manager

• Completely eliminated the severe O(n²) performance bug in the Backup Manager
  → Previously caused 30–60+ minute load times (or even hours) when users had thousands of backup files, especially on ZFS or slow filesystems.
  → Fixed by pre-computing .save file indices in a single directory pass.
  → Backup list now loads in seconds even with 5000+ files.
• Dropped support for the legacy (pre-terrain-update) save/backup format in the new Backup Manager
  • Starting a pre-terrain dedicated server still works perfectly fine
  • The Backup Manager now strictly enforces / only works with the new terrain system
• Added a very noticeable warning in the config loading when loading preterrain SSUI
• Added a collapsible info banner on the dashboard explaining the change
• Migration of saves (also powered by JacksonTheMaster, the author of SSUI): https://sst.jxsn.dev

Fixes & Polish

• *Fixed console auto-scroll to bottom (finally)
• Removed duplicate scrollbar in console window
• Fixed re-advertising to Steam master servers when IP or game version changes
• Minor UI/dashboard improvements and text fixes
• Updated World ID guidance text in world config
• refactored CSS to enhance use of variables for improved theming and consistent styling across UI components
• added silly xmas styling (conditional from 1st of Dec to 10th of Jan)

Version

Now at 5.9.1 (includes internal hotfix 5.8.1 )

Jackson

SSUI v5.6.5 - Orbital Homecoming 💾

Tip

The new terrain system was released by RocketWerkz! UseNewTerrainAndSaveSystem is now true by default!

💾 This release adds changes needed to default to the new Stationeers Terrain and Save system, as well as updating their respective localization strings to show "Terrain" values rather than "Beta Terrain" texts as before.

Swedish and German will fallback to English for now as localization is not done for those yet, this will be addressed in the next release.

Features and Fixes ✅⚙️

• Changed UI texts and default to new terrain system
  • Missing swedish and german localizations atm, will fallback to english
• fixed worldOptions in Save Identifier setup step showed old worldIDs if newterrain was enabled
• Changed UseNewTerrainAndSaveSystem" default is now true!

This release also includes substantial improvements to the Docker container of StationeersServerUI - a huge thx to @1Solon. We now offer a prebuilt container on ghcr.io. Documentation will be updated shortly.

General repo improvements

• Updated NPM dependencies and rm electron entirely
  Removed lines in PR / release are mostly due to electron being beeing red / removed
  • Electron was leftover from SteamServerUI and is not needed in this repo
• Added Github CodeQL to repo

New Developers

Also I want to take the opportunity and welcome @akirilov to the team here! 🎉🥳
