Smart Bundles technology for optimized downloads, Launcher Build Management, xxHash64 implementation and much more
🖥️ Desktop
[NEW] Smart Bundles Technology
NEW FEATURE: Revolutionary Smart Bundles system for dramatically faster downloads!
IMPORTANT: This new feature is only available for newer builds and launchers.
Example: A 1.16 GB game with 309 files is now 1.07 GB with only 5 files because most of its assets were small files.
What's New:
Smart Bundles - Automatic grouping of small files into optimized packages
Faster Downloads - Dramatically reduced overhead for games with many small files
Efficient Storage - Better compression and organization of game assets
Adaptive System - Intelligently bundles files based on size and update patterns
Build Metrics - Track bundle counts, sizes, and file counts per build
How It Works:
Small files (less than 5 MB) are automatically bundled during patch generation. The launcher downloads and extracts these bundles seamlessly, providing a much faster experience especially for games with thousands of small assets.
Performance Impact:
~20% additional storage overhead during patch generation for bundle optimization, but significantly faster download speeds for end users.
[NEW] Global Minimum Version Enforcement
NEW FEATURE: Launcher now enforces minimum version requirements on startup!
What's New:
Project Metadata Update - Updated versioning and project configuration in csproj files
Automatic Version Check - Launcher enforces minimum version requirements on startup
Forced Updates - If the launcher version is older than the minimum required version, it will be forced to update
User Protection - Ensures all users are on supported versions with latest security and performance improvements
Platform Access Control - Prevents outdated launchers from accessing the platform
Impact:
This ensures all users maintain compatible launcher versions and benefit from the latest performance improvements and security updates.

[NEW] xxHash64 Implementation
MAJOR PERFORMANCE UPGRADE: Revolutionary hash algorithm replacement for dramatically faster patch creation and file verification!
IMPORTANT - Transition Period:
For the next 2 weeks, server-side builds will generate patches with both MD5 and xxHash64 to maintain compatibility with older launchers.
After this transition period, only xxHash64 will be used for new builds. Users with outdated launchers will need to update to a recent version to continue receiving game updates.
This change will enable significantly faster build processing on the server, reducing build times and improving overall system performance.
What Changed:
xxHash64 is Now Primary - xxHash64 is now the primary hashing method for all new patch operations
Optional MD5 Support - MD5 hash generation available for backward compatibility when needed
Massive Speed Boost - Hash calculation is now significantly faster during:
Patch creation and generation (local and server-side)
File verification during downloads
Build integrity checks
Update detection processes
Server-side build processing
Performance Impact:
xxHash64 is up to 10-20x faster than MD5, resulting in:
Faster patch generation - Developers can create patches much quicker (both locally and via CLI)
Faster file verification - End users experience shorter verification times
Reduced CPU usage - More efficient processing during build creation
Quicker update checks - Faster comparison of file states
Faster server-side processing - Backend API generates patches significantly faster, reducing build queue times and server load
Compatibility & Migration:
Backward Compatible - The launcher is fully compatible with existing patches created with MD5
Automatic Detection - System automatically detects which hash algorithm was used for each patch
Old Patches (MD5) - Previously created patches continue working without any issues
New Patches (xxHash64) - All newly created patches automatically use the faster xxHash64 algorithm
To Take Advantage - Create a new patch for your game and update the launcher to benefit from the massive speed improvements
This is a fundamental performance improvement that affects every aspect of the patching and verification system, from server-side build generation to end-user file verification.
🌐 Dashboard
[NEW] Launcher Build Management System
NEW FEATURE: Complete build version control for your launcher!
IMPORTANT: After deploying a new launcher build, you must manually set it as the Active Build. This allows you to test your changes before all users receive the update, ensuring a smooth rollout process.
What's New:
Builds Tab - New dedicated section in launcher settings for build management
Active Build Selection - Choose which build version users download
Protected Deletion - Cannot delete the currently active build (safety feature)
Multiple Download Formats:
Windows Installer (.exe)
Portable ZIP package
Copy Download Links - Share direct download URLs with one click
Detailed Build Metrics:
Executable ZIP upload duration
Installer upload duration
Total build time
File sizes and configuration
Visual Preview - View launcher icon and splash screen directly in the list
Build History - Keep track of all previous launcher versions
Where to Find:
Dashboard → Launchers → Select Launcher → Builds Tab
[NEW] Persistent Download URLs & Copy to Clipboard
IMPROVEMENT: Stable download links and easy sharing with copy-to-clipboard!
What's New:
Copy to Clipboard - One-click copy for both Installer and ZIP download links
Persistent Latest URLs - Download links always point to the same URL structure
Latest Folder System - Active build files automatically copied to
/Latest/folderAutomatic Updates - When you activate a new build, the Latest folder updates automatically
How It Works:
Previously, download URLs changed with each build number (e.g., Build_297/). Now, the active build is always available at a consistent URL:
Benefits:
Single Download Link - Share one permanent URL with your users
Always Current - Users always download the active build version
Easy Sharing - Copy button makes it simple to distribute links
CDN Powered - Fast global downloads via Cloudflare CDN
When you activate a different build, the files in the Latest folder are automatically replaced with the newly selected active build.
