The Web SDK migrates replay data between adjacent format versions, both upward and downward.
| Migration | Behavior |
|---|
| v3.2.0 → v3.3.0 | Adds an empty props.effects stack ([]) to every visual layer — including fallback layers and layers added by actions. See Effects |
| v3.3.0 → v3.2.0 | Version-only downgrade: the effects property is left in place for forward compatibility |
