Version Compatibility

Know which Studio, plugin, package, protocol, and Unreal versions work together.

CalmUI 0.1.0-rc.32 works with these versions:

Connection	Rule
Studio and plugin	Product line `0.1` is compatible. A different major or minor line requires an update.
Studio and Development protocol	Both must use protocol `1.14`.
Plugin and Core	The plugin ships its matching Core `0.1.0-rc.32`; mixing native libraries is unsupported.
Runtime and `.cuipack`	Runtime reads package format `1.0` through `1.14`.
Package and Store/Actions	Schema version is `1`; Store and Action hashes must match when required.
Plugin and Unreal	Unreal Engine `5.7.4` on Windows x64 is validated. The `5.7` line is supported. Other versions are unsupported until tested.

A package outside the readable range is rejected with a version error. The last working package stays active. Update Studio and the Unreal plugin together before rebuilding your packages.

Before 1.0, a major or minor product update may contain breaking changes. Such changes must include release notes and a migration path.
