This page lists the currently published engine SDK package versions and download links in IGP Developer Docs.
Each version has a fixed download link. For production projects, always pin an exact version instead of using latest.
Each engine maintains its own SDK version. See the Unity Changelog and Godot Changelog for concrete changes.
These are the recommended SDK versions for each engine, together with their supported engine versions and available packages.

Suggested upgrade rules while the packages are still in preview:
Pin versions : record the exact engine SDK version in use. Do not point to latest/.Keep a copy of old packages : back up previous .unitypackage or .zip files before upgrading so rollback stays easy.Expect breaking changes : preview patch releases may still contain breaking changes. These changes are documented in the corresponding engine Changelog.
