# 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.
