Migration notes: godot-economy-system

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

No skill-relevant breaking changes for this hop.

4.1 → 4.2

Official: Upgrading to Godot 4.2

No skill-relevant breaking changes for this hop.

4.2 → 4.3

Official: Upgrading to Godot 4.3

Re-test save formats after Object/Array serialization and PackedByteArray storage changes.
Scripted Object / typed Array binary serialization changes — verify Resource round-trips.
Large PackedByteArray storage format may not open in older editors.

4.3 → 4.4

Official: Upgrading to Godot 4.4

Encrypted FileAccess / store_* bool returns — handle failures; UID paths in exported files.
@export_file → uid:// in Inspector-assigned values.
Curve clamps to configured min/max.

4.4 → 4.5

Official: Upgrading to Godot 4.5

Resource deep-duplicate and UID export-file changes affect inventory/quest/economy Resource graphs.
Deep-duplicate semantics when cloning save-related Resources.
Resource.duplicate(true) no longer deep-copies external resources by default.

4.5 → 4.6

Official: Upgrading to Godot 4.6

Scene unique IDs change diffs — migrate save schemas if they keyed on old node identity assumptions.
First save in 4.6 rewrites scenes with unique node IDs.

4.6 → 4.7

Official: Upgrading to Godot 4.7

Re-validate Resource pipelines after packed-array setter and typed-return GDScript changes.
