Support Categories Explained

🚀 Active Support (Recommended)

These versions are fully optimized and continuously tested on Arcware Cloud servers. We guarantee full compatibility with our WebSDK, templates, and performance optimizations. We highly recommend starting all new projects on one of these versions.

⚠️ Deprecated Support (End of Life)

Deprecated versions are legacy releases that will soon phase out of our active support cycle.

• What this means: While existing packaged projects may continue to stream, we will no longer release template updates, bug fixes, or dedicated technical support for these versions.

• Our recommendation: If your project is currently on 4.27 or 5.0.3, we strongly suggest migrating your assets and logic to UE 5.6 or higher for the best streaming experience.
