Changelog

Version: 0.2.25
Date: 2026-10-08
  Bugfixes:
    - Game no longer fails to load with belt mods that redraw belts (e.g. Black Rubber Belts): packer belt picture now matches the belt's own animation length.

Version: 0.2.24
Date: 2026-10-06
  Bugfixes:
    - With overhaul mods that move recipes to other technologies (e.g. Pyanodon's), packer technologies no longer depend on the old technology: they now look up which technology unlocks each ingredient after all mods have loaded. In Pyanodon's, the Fast Sushi Packer now comes right after Logistics 2 instead of much later.

Version: 0.2.23
Date: 2026-10-04
  Features:
    - Hold Alt to see which way each sushi packer runs: one arrow per packer, pointing the way items leave.
    - Each lane now holds at most one item stack of one kind (e.g. 100 iron plates, 50 ore). When the front belt is blocked, one kind can no longer fill the whole lane; it is taken again once half a stack has left. At most 5 kinds per lane are limited at once.
  Changes:
    - Alt-mode no longer shows the icons and arrows of the hidden parts inside a packer.
  Bugfixes:
    - A packer with no belt behind or in front no longer draws extra copies of its hood on the tiles next to it (since 0.2.20).

Version: 0.2.22
Date: 2026-10-02
  Optimizations:
    - Boxes use less script time: the hood is now drawn as a picture instead of a hidden entity. Measured about 13 % less script time on a 270 items/s modded belt.
  Changes:
    - Removed old unused code.

Version: 0.2.21
Date: 2026-10-02
  Bugfixes:
    - The belt in front of a box moved in jerks when it carried many item kinds or single, unstacked items: the hidden inserters waited to fill their hands. One of every four now takes single items and never waits.
    - With more item kinds than lane slots a box filled up and stopped taking. A lane now holds 24 kinds (was 12). Boxes with pass-through filters let the oldest leftover out when a lane is full.
    - Very fast modded belts (above 144 items/s): a box passes a fully stacked belt at belt speed.
  Changes:
    - The box window shows lane slots in rows of 12.

Version: 0.2.20
Date: 2026-10-02
  Bugfixes:
    - Items piled up inside a box and little came out when many item kinds arrived, for example the same items in several qualities: every hidden inserter was holding a leftover of another kind. Such a lane now lets its inserters take only kinds that have a full stack.
    - The box window shows the quality of every stored item.
    - Blueprints and ghosts show the box with its hood instead of a bare belt with a wire frame.

Version: 0.2.19
Date: 2026-10-02
  Bugfixes:
    - Loading a save made before 0.1.17 could fail with "invalid key to 'next'" (depended on how many boxes the save held).

    - Loading a save made before 0.1.17 could fail with "invalid key to 'next'" (depended on how many boxes the save held).

Version: 0.2.18
Date: 2026-10-02
  Bugfixes:
    - With a belt running across in front of the box, leftovers of one item split over two hidden inserter hands were never joined and stayed inside.

Date: 2026-10-02

    - With a belt running across in front of the box, leftovers of one item split over two hidden inserter hands were never joined and stayed inside.

Version: 0.2.17
Date: 2026-10-02
  Changes:
    - The box is now a belt piece instead of a chest: the game rotates it like a belt (R), and upgrade planner, copy-paste and blueprints carry its circuit settings like on a belt.
    - Circuit network: enable condition and "read contents" are the belt's own settings. Read contents shows every item inside the box and is on by default.
    - A belt running across in front of the box now gets the stacks on its near lane, like from a belt. A belt pointing at the side of the box puts nothing in.
    - Inserters next to a box drop onto its belt piece (the items get packed) and take only what lies on that piece, not stored items.
    - The box has its own window (click it). Items shown there can no longer be taken by hand; mine the box to get them.
    - The box item no longer has rotate key bindings of its own.
    - Boxes in existing saves and blueprints are converted on load; items, settings and wires are kept.
  Bugfixes:
    - A rotated or upgraded box with nothing in front could drop stored items on the ground.

Version: 0.2.16
Date: 2026-10-02
  Optimisations:
    - With belt stacking from Space Age (or another mod that enables it), hidden inserters now also put the stacks out. The script only checks each box about twice per second: script time is 15 or more times lower than in 0.1.14.
  Changes:
    - Items below one full stack wait in a hidden inserter hand; the box window does not show them, the light does.
    - A lane no longer limits itself to one stack per item, and stacks leave in no fixed order.
    - A box passes up to about 1.6 times the speed of its own belt tier.
    - Inserters next to a box can take items from it again.
    - Boxes with pass-through filters, and games without the belt stacking feature, keep the 0.1.15 behaviour.
  Bugfixes:
    - Items held by the hidden inserters are returned when a box is mined, rotated or destroyed.

Version: 0.2.15
Date: 2026-10-01
  Changes:
    - The box window shows both lanes in two rows, and you can take items by clicking them.
    - Each lane holds 12 slots.
    - Boxes in old saves keep every item; those items leave first.
  Optimisations:
    - The box uses much less script time: hidden inserters take items in, lanes stay separate.
