DLC Support (Dashboard, Desktop Launcher & CLI), Smart Bundle Exclusive Mode, Build File Viewer, Auto-Link App/Launcher, Environment Alias, CLI v1.2.0
Dashboard
DLC Management
NEW FEATURE: Full Downloadable Content (DLC) support is now available! Create, manage, and deploy DLC packages for your games — all from the Dashboard.
You can now manage DLCs directly from a dedicated DLC tab inside each App. Create DLC entries with custom names, covers, install modes, and optional interaction URLs that players can click in the launcher.
What is Downloadable Content (DLC)?
It works exactly as an app build but optionally to install. E.g. Winter Extension Pack
Key capabilities:
Create & Edit DLCs
Add DLC entries with name, cover image, install mode and interaction URL
DLC Builds
Upload DLC builds and assign them to environments, just like app builds
Merge Builds
Create merge builds by selecting a baseline build and specifying removed paths
Install Mode
Subfolder
DLC will be installed in the DLC subfolder of the app
Independent
DLCs can be installed in a custom folder chosen by the player
Interaction URL
Optional URL that opens when a player clicks the DLC cover or title
Storage Optimized Builds (Smart Bundle Exclusive Mode)
NEW FEATURE: Builds can now use Storage Optimized mode, which drastically reduces build processing times — especially for Merge Builds and projects with very large numbers of files.
The Problem
Previously, when uploading a build, small files (<5MB) were grouped into Smart Bundles to optimize downloads. However, those small files were also uploaded individually to Cloudflare storage.
This allowed fast file repair, but caused two issues:
Much longer upload times — imagine 50,000+ files uploading one by one
More storage usage — builds consumed more quota than necessary
The Solution
Small files will no longer be uploaded individually, since they already exist inside Smart Bundles.
How it works by build type:
Standard builds
Only large files and Smart Bundles are uploaded
Merge builds
Smart Bundles are downloaded and extracted instead of thousands of individual files
Launcher repair: If a file is missing or corrupted, the launcher will download the Smart Bundle containing that file and repair the game automatically.
Result: Much faster uploads, faster merge builds, and more efficient storage.
A Storage Optimized badge is displayed in the build details view when a build uses this mode.
BREAKING CHANGE: Older launchers will not be able to download builds processed with Storage Optimized mode.
By default the Storage Optimized builds are DISABLED on existing launchers.
STORAGE OPTIMIZED BUILDS MAKES A HUGE DIFFERENCE IN THE BUILD COMPILATION AND STORAGE USED FROM 10 MINUTES TO 1 MINUTE BUILD TIME
How to enable Storage Optimized builds
Deploy a new launcher build and set it as the active build
Navigate to Launcher Advanced Settings and Enable Storage Optimized Builds.
That's all! Your next app build will use it!
After 30 days this option will be checked automatically.
Build File Viewer
NEW FEATURE: The build details page now includes a powerful file viewer with tree view, bundles view, sorting, pagination, and file integrity information.
Explore your build files in three different views:
Flat view — Traditional file list with sorting and pagination
Tree view (now default) — Hierarchical folder structure with expand/collapse controls
Bundles view — Files grouped by Smart Bundle, with expandable bundle groups
Additional improvements:
Sortable columns — Click column headers to sort by path, file size, hash, or bundle ID
File hash & bundle info — Each file now displays its hash (xxHash64 or MD5) and Smart Bundle membership
Change & compare toggles — For merge/delete builds, visualize added, modified, and deleted files with diff icons and color highlights
Resizable columns — Drag to resize the file path column
Responsive layout — Improved support for smaller screens
Environment Alias Display
Environments now display their alias (when configured) in the App Builds instead of the raw environment name across build lists, DLC entries, and environment selectors.
Possible Previous Install Locations
Support for detecting the game installation in the same root of the Launcher.
<LAUNCHER_ROOT>
The Possible Previous Install Locations setting now supports a special <LAUNCHER_ROOT> token that resolves to the launcher's installation folder at runtime. This is useful for detecting previous installations relative to where the launcher is installed.
Build Processing Improvements
NEW FEATURE: Now you can see the progress of the current stage of a build!
Desktop Launcher
DLC Manager
NEW FEATURE: The Desktop Launcher now fully supports DLCs! Players can browse, install, uninstall, and manage downloadable content directly from the launcher.
A new Manage DLC option is available in the app settings dropdown. From the DLC Manager window, players can:
Browse available DLCs with cover images and descriptions
Install / Uninstall individual DLCs with a toggle switch
Independent install mode — Choose a custom folder for DLC installation
Auto-verification — Installed DLCs are automatically verified in the background using checksum validation
Interaction URL — Click on a DLC cover or title to open the developer-configured URL
Open install folder — Quickly open a DLC's install folder in the file explorer
Repair integration — DLC verification is included as part of the Repair Game flow
CLI
Version 1.2.0
NEW VERSION: CLI v1.2.0 is now available with full DLC support and improved progress display.
New commands:
dlc-upload
Upload DLC builds with interactive flow and progress
dlc-status
Check DLC build processing status (watch/json modes)
It includes other minor fixes.
Core Engine
Performance Optimizations
Significant performance improvements for patch creation and file processing:
O(1) file lookups
Dictionary-based lookups replace linear searches
Parallel bundle creation
Up to 8 threads for Smart Bundle creation
Parallel hashing
Up to 8 threads for file hash computation
Parallel compression
Up to 12 threads for compression operations
Memory-efficient traversal
EnumerateFiles replaces GetFiles to reduce allocations
Parallel incremental diffs
Two-phase approach: collect candidates then process in parallel
