Summary: Beta 6 is primarily a bug-fix release focusing on stability improvements. Six significant issues from Beta 5 were resolved, including critical problems with EyeSight display, Foundation Models guardrail violations, and cross-platform compatibility for RemoteImmersiveSpace. Only two new minor issues were introduced, both related to UI presentation edge cases. This represents strong progress toward release readiness with a net reduction in known issues.
