Smart Bundles technology for optimized downloads, Launcher Build Management, xxHash64 implementation and much more
🖥️ Desktop
[NEW] Smart Bundles Technology
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
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Platform Access Control - Prevents outdated launchers from accessing the platform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.
⚡ Core Features
GameLauncherCore (v2.1.1.0)
[NEW] xxHash64 Implementation
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.

[NEW] Persistent Download URLs & 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.
