Migration notes: godot-genre-metroidvania

Incremental upgrade for topics this skill covers. Apply one hop, stabilize/test, then next. Never skip hops.

If the project is < 4.0, follow godot-version-migration era bridges (legacy → 3→4) until 4.0, then these hops. Official 3→4: Upgrading from Godot 3 to Godot 4.

4.0 → 4.1

Official: Upgrading to Godot 4.1

• PathFollow2D.lookahead removed.

4.1 → 4.2

Official: Upgrading to Godot 4.2

• TileMap.cell_quadrant_size → rendering_quadrant_size.

4.2 → 4.3

Official: Upgrading to Godot 4.3

• If the genre uses TileMap, migrate to TileMapLayer nodes before relying on layer APIs.
• If the genre ships multiplayer, upgrade all peers to 4.3 together (SceneMultiplayer protocol).
• TileMap layers moved to TileMapLayer nodes — migrate scenes/scripts to per-layer nodes.
• TileData.get_navigation_polygon / get_occluder gain flip/transpose optionals.

4.3 → 4.4

Official: Upgrading to Godot 4.4

No skill-relevant breaking changes for this hop.

4.4 → 4.5

Official: Upgrading to Godot 4.5

• TileMapLayer.get_coords_for_body_rid less precise with physics chunking — set physics_quadrant_size = 1 for old precision.

4.5 → 4.6

Official: Upgrading to Godot 4.6

• Retune Environment glow/fog if the genre leans on bloom-heavy looks.

4.6 → 4.7

Official: Upgrading to Godot 4.7

• Confirm project stretch mode and AudioStreamPlayer area_mask after opening in 4.7.
