Unity Breaking Changes

Purpose

Surface version upgrade and compatibility risks before relying on engine behavior.

Guidance

• Call out migration-sensitive APIs, package versions, serialization formats, and build settings.
• Separate confirmed breaking changes from speculative compatibility risks.
• Include rollback or compatibility notes for risky changes.

Validation

• Prefer project-local engine commands and Codex Game Studio project validation before readiness claims.
• Record unknown version-specific behavior as a risk instead of presenting it as confirmed.
• Keep this reference selected by relevance; do not load every engine reference for one task.
