Unity Deprecated APIs

Purpose

Avoid stale APIs and migration traps when editing or reviewing engine code.

Guidance

• Check version-specific deprecations before copying older snippets.
• Prefer supported APIs and document unavoidable legacy use.
• Treat deprecated APIs as warnings unless the task is a migration or compatibility fix.

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.
