    `->getBox()` and `->getItems()`
  - `NoBoxesAvailableException` now has a `getAffectedItems()` method instead of `getItem()`. This should allow
    improved handling of the exception inside calling applications when multiple items cannot be packed
- - Calling `json_encode()` on a `PackedBox` or `PackedItem` now additionally serialises the entire underlying
-   `Box`/`Item` where those objects also implement `JsonSerializable`. Previously the serialisation only included the
-   key values from the `Box`/`Item` interfaces themselves.
 ### Removed
  - Removed deprecated `ConstrainedItem`. You should use `ConstrainedPlacementItem` as a replacement
  - Removed `getKeepFlat()` from the `Item` interface
  - Removed `InfalliblePacker`. You can now get the same behaviour by calling `->throwOnUnpackableItem(false)` and
    `->getUnpackedItems()` on the main `Packer` class
