Godot Version Migration

Orchestrator for engine version upgrades from early Godot through the library target. Domain Skills document current APIs; this hub owns the upgrade path.

Library target: Godot 4.7+

Corpus: docs changelog · interactive changelog · download archive · GitHub releases · migrating index

NEVER Do

NEVER skip majors — route 1.x → 2.x → latest 3.x → 4.0 before any 4.x minor ladder.
NEVER skip 4.x hops — upgrade 4.0 → 4.1 → … → 4.7 one minor at a time; stabilize after each hop.
NEVER claim automatic 1.x→4.x conversion or bit-exact autopilot.
NEVER treat Domain Skill bodies as migration changelogs — load references/<topic>.md (mirrored from each skill’s references/migration-notes.md).
NEVER load all module notes at once — only subsystems present in the project.
NEVER mix server/client Godot minors for high-level multiplayer (especially across 4.2→4.3 SceneMultiplayer protocol changes).
NEVER choose Mesh “Restart & Upgrade” without VCS backup (4.1→4.2 mesh format).
NEVER run the 3→4 converter without a full backup (tool does not backup).

Version detect

Read project.godot (config_version, config/features) or legacy engine.cfg.
Ask the user if files are ambiguous.
Map to an era in references/era-index.md.

Workflow router (MANDATORY)

Detected era	Load	Do NOT
1.x / early 2	legacy/pre-2-context.md	Invent a 1→4 converter
2.x	legacy/2-to-3.md then stabilize on latest 3.x	Jump straight to 4.7 notes
3.x	bridges/3-to-4.md + official 3→4 guide	Skip latest-3.x stabilize gate
4.x `< 4.7`	Official hop guide + hop-index.md module notes for touched systems	Skip minors
Already 4.7+	godot-master / Domain Skills	Treat this hub as a coding tutorial

Steps (4.x minors)

While current < 4.7, perform exactly one hop to current + 0.1.
Open the official upgrading page for the destination version.
From hop-index.md, open only module notes for subsystems present in the project.
Apply fixes; open in the new editor; playtest; repeat.

Module directory

Mirrored Domain Skill migration notes live at references/<topic>.md (e.g. references/2d-physics.md). Hub-native legacy/, bridges/, and era-index.md are not Domain Skill mirrors.
