# Unreal Engine Version Support

General Goal: To provide a transparent overview of which Unreal Engine versions are natively supported, deprecated, or coming soon on the Arcware Cloud platform. This page helps you plan your project development and upgrades to ensure seamless compatibility with our cloud streaming infrastructure.

### 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.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.arcware.cloud/unreal-engine-setup/unreal-engine-version-support.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
