Migration notes: godot-genre-visual-novel

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

• SubViewportContainer.mouse_filter must be STOP/PASS for input to reach SubViewports (character portrait layers).
• Layered SubViewportContainers needing mouse input may need Area2D replacements.
• RichTextLabel.push_list gains bullet; push_paragraph gains justification/tab_stops optionals.

4.1 → 4.2

Official: Upgrading to Godot 4.2

• RichTextLabel.add_image gains key, pad, tooltip, size_in_percent optionals.
• PopupMenu shortcut helpers gain allow_echo; clear gains free_submenus.

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).
• Default font outline color is black (was white) — retune dialogue/nameplate themes.
• auto_translate deprecated for Node auto_translate_mode (inherit semantics) — verify localized choice menus.
• RichTextLabel.push_meta gains underline_mode.
• AcceptDialog register/remove helpers take LineEdit/Button specifically.

4.3 → 4.4

Official: Upgrading to Godot 4.4

• RichTextLabel.push_meta gains tooltip; set_table_column_expand gains shrink.

4.4 → 4.5

Official: Upgrading to Godot 4.5

• add_image/update_image: size_in_percent replaced by width_in_percent and height_in_percent — set both for inline CG/sprite sizing.
• CanvasItem/Font/TextLine draw APIs gain optional oversampling.
• TreeItem.add_button gains alt_text (choice/history lists).

4.5 → 4.6

Official: Upgrading to Godot 4.6

• Retune Environment glow/fog if the genre leans on bloom-heavy looks (title screens, dream sequences).
• Control.grab_focus / has_focus gain hide-focus options — useful for auto-advance vs keyboard focus.
• PopupMenu.submenu_popup_delay default 0.2 (was 0.3).

4.6 → 4.7

Official: Upgrading to Godot 4.7

• Confirm project stretch mode and AudioStreamPlayer.area_mask after opening in 4.7.
• width_in_percent/height_in_percent → width_unit/height_unit with RichTextLabel.ImageUnit — migrate inline CG/sprite tags.
• ImageUpdateMask.UPDATE_WIDTH_IN_PERCENT → UPDATE_WIDTH_UNIT.
• add_image/update_image width/height are float — NEVER pass bool percent flags.
• CanvasItem no longer adds antialiasing feather that thickened lines — widen dialogue box strokes if borders looked bolder.
