Migration notes: godot-tweening

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.

• PathFollow2D.lookahead removed.
• SubViewportContainer.mouse_filter must be STOP/PASS for input to reach SubViewports.
• Layered SubViewportContainers needing mouse input may need Area2D replacements.
• CodeEdit.add_code_completion_option gains location; Tree edit_selected gains force_edit.

4.1 → 4.2

• AnimationMixer._post_process_key_value object arg is uint64.
• Skeleton3D.bone_pose_changed → skeleton_updated; BoneAttachment3D.on_bone_pose_update → on_skeleton_update.
• Capture mode replaced; see Migrating Animations 4.0→4.3 article for blend/time semantics.
• Default font outline color is black (was white).
• auto_translate deprecated for Node auto_translate_mode (inherit semantics).
• AcceptDialog register/remove helpers take LineEdit/Button specifically.

4.3 → 4.4

Official: Upgrading to Godot 4.4

4.4 → 4.5

Official: Upgrading to Godot 4.5

• CanvasItem/Font/TextLine draw APIs gain optional oversampling.
• TreeItem.add_button gains alt_text.

4.5 → 4.6
