v5 is back in LTS! Added .save and new systems support and various other awesome features merged from SteamServerUI (and fixes)

[JacksonTheMaster]

Full support for OLD and NEW Terrain System!

Important

To use SSUI with the current Stationeers Beta, visit Config -> Beta Settings -> Use New Terrain and Save System -> True.

Most importantly: SSUI is back in LTS until end of 2026!

This update focuses on boosting performance, enhancing usability, and ensuring compatibility with Stationeers' upcoming terrain rework. Here are the key changes:

It introduces several significant enhancements to the StationeersServerUI project, updating backup management to handle the new and old system side by side with the switch of a config value, embedding web UI assets to eliminate excessive GitHub API requests , and introducing a command-line interface (SSUICLI).

The changes aim to improve QOL, usability, and full compatibility with Stationeers' upcoming terrain rework.

Changes:

🗺️ Full New Terrain and Save System Support

Core Compatibility Features

Ensure IsNewTerrainAndSaveSystem is set to True in Config -> Beta Settings for Stationeers Beta compatibility.

• Dual system support: Toggle between old and new Stationeers systems with IsNewTerrainAndSaveSystem config option
  Added configuration options for Difficulty, StartCondition, and StartLocation to support the new terrain systems file start command fully
• Enhanced UI: New "Beta Settings" (will change to World Settings once Beta is released to stable) section for configuring terrain and world generation options
• Automatic saving into HEAD Save: When enabled with new terrain system, backup manager automatically saves to HEAD Save on every autosave
• Default world update: Now uses 'Vulcan' (compatible with both stable and beta). 'Moon' has been renamed to 'Lunar'.

💾 Backup Manager Enhancements

New Features & Improvements

• .save file support: Full compatibility with new backup format alongside legacy system
• Smart directory watching: Monitors autosave directory for both old and new systems
• Improved restore process: Refactored restore process to handle both .save files and legacy backup trios (.bin, .xml, world_meta.xml), with improved error messages using the term "autosave watcher".
• Improved backup manager: Now starts asynchronously, ensuring smoother world creation and backup processes by waiting for Stationeers to initialize the world folder instead of creating it.
• Squashed bugs across both new and old backup systems for a flawless experience.

📦 Performance & Asset Optimization

Web UI Asset Bundling

• Embedded all web UI assets (HTML, CSS, JS) into the executable using Go's embed package, eliminating 20+ excessive GitHub API calls per startup
• Added cleanup logic to remove old files (post-v5.5) and auto-migrate customdetections.json to the config folder (src/loader/loader.go).
• All SSCM assets besides the actual DLL are now bundled to further reduce github.com api calls

🖥️ Introducing SSUICLI: The Command-Line Powerhouse:

• Unleash a CLI with commands like:
  • help - Display available commands
  • reloadbackend - Reload backend systems
  • reloadconfig - Reload backend config only
  • restartbackend - Restart backend completely
  • startserver - Start game server
  • stopserver - Stop game server
  • deleteconfig - Remove configuration
  • runsteamcmd - Execute SteamCMD operations
• Total control at your fingertips!
• Stylish startup and first-time setup messages for a polished user experience.
• Disable SSUICLI via the IsConsoleEnabled config option (defaults to true!).

SteamCMD integration:

• Direct triggering: Launch SteamCMD from both the WebUI and SSUICLI
• UI integration: Repurposed API info button as Update Server button
• Rate limiting: 30-second cooldown to somewhat prevent spam

🎮 SSCM (Stationeers Server Command Manager)

Out of Beta & Enabled by default

• Production ready: SSCM is no longer in beta status
• Opt-out: SSCM is now enabled be default and requires an opt-out during setup.
• Improved command handling: Can now run the same command without chaining requirements
• Enhanced UI display: Command arguments properly rendered in interface
• File cleanup: Removed unnecessary SSCM.pdb from downloads

🌍 Localization System

Multi-Language Support (Public Beta)

• Only via config.json: As localization is not nearly close to done, no webUI config option has been added yet!
• Languages available: English (default), German, and Swedish.
• Localized sections:
  • Main page (/): Most buttons and UI elements
  • config page (/config): Whole page done
  • setup track (/setup): Whole visual page is done, but API responses still in English (e.g. "cannot finalize setup at this time)
• API responses generally NOT localized: Messages like "Server started" or "backup restored successfully" are NOT" localized in this update and are shown in English.
• Translation status: German and Swedish translations are available but will receive updates in the future.
• Future plans: Additional languages and refined translations are planned.

🛠️ System Improvements & Bug Fixes

Configuration & Backend

• Thread-safe config loading: Improved stability during configuration access
• Full backend reloads: Config changes now trigger complete backend reload
• Streamlined initialization: All systems initialized only once, reducing startup clutter
• Improved setup flow: Setup finalize now performs full backend reload
• Better config management: Moved SaveConfig to loader package for proper startup saving

User Experience

• Enhanced setup: Added a "Pls read" step in setup to minimize user errors (fingers crossed 🤞).
• Improved beta selection: Better emphasis on restart requirements
• Cleaner logging: Added LogClutterToConsole config option to suppress unnecessary game server messages
• Reduced sunset warning: Removed big red "This tool might break, use SteamServerUI" warning (since this update was made despite me thinking it would be too much work, turns out it was doable)
• Better error handling: Enhanced backup manager error messages and flow

Development & Maintenance

• Cleanup logic: Old executables rename automatically on update to _old<filename> for better startup scripting
• Improved updater: Now correctly grabs prereleases with more verbose logging
• API endpoint info: Now linked in footer on main page
• Log message cleanup: Updated messages and removed unnecessary whitespace
• Consistent CLI output: Re-added Arguments printing in start server CLI log output on Linux

🛠️ Miscellaneous:

• Eliminated 2-second sleep delay between logging and SteamCMD installation for smoother execution (install.go).
• Updated .gitignore for seamless development on Linux (previously Windows for StationeersServerUI, Linux for SteamServerUI).
• Updated dependencies (gorilla/websocket, crypto, sys) for peak performance.
• Fixed critical issue (Memory Leak in InternalIsServerRunning Due to Goroutine Accumulation on Windows #68): Memory leak in InternalIsServerRunning due to goroutine accumulation on Windows. 🐛
• Moved ReloadBackupManager() to ReloadConfig() for better flow.
• Enabled SSUICLI by default and clarified non-interactive shell usage in the console input stop message.
• Re-added Arguments in start server CLI log output on Linux for consistency with Windows...
• Config LOADING is now thread safe
• Saving config from ui now redirects to /config instead of / for better UX
• switched positions of AdminPassword and ServerAuthSecret in UI
• Added AutoStartServerOnStartup config option
• added function to loader to install a script (.ps1 or .sh) to configure an os based autostart behavior for SSUI automatically. You only need to run the script once, and SSUI will autostart from that point onwards.
