Date: 2026-08-04

  Features:
    -- Added optional 9x9 logistic chest variants:
      - Passive provider chest
      - Storage chest
      - Buffer chest
      - Requester chest
    -- Added separate startup settings to enable or disable each logistic chest variant.
    -- Added a shared startup drop-down setting controlling the research unlock behaviour of the 9x9 passive provider and storage chests.
    -- Added a custom animated robot hatch to all enabled 9x9 logistic chest variants.
    -- Added a robot-door sound using Factorio's built-in mechanical large opening sound.
    -- Added automatic fallback to Factorio's standard logistic chest opening sound definition if the preferred sound definition is unavailable.

  Research:
    -- Added the "Non Vanilla - Logistic System Research" unlock option.
    -- When the non-vanilla option is selected, both the 9x9 passive provider chest and the 9x9 storage chest are unlocked by Logistic system research.
    -- Logistic system is the same vanilla research that unlocks requester and buffer chests.
    -- Added a "Vanilla" option that unlocks the 9x9 passive provider and storage recipes from the same technologies as their corresponding vanilla chest recipes.
    -- The non-vanilla Logistic system option is selected by default.
    -- The requester and buffer variants continue to follow their corresponding vanilla research unlocks.
    -- The original filtered 9x9 steel chest continues to unlock with Rocket Silo research.

  Recipes:
    -- Updated logistic chest recipes to use the complete ingredient list of the selected filtered 9x9 steel chest recipe-cost preset.
    -- Logistic chest recipes now add preset-specific quantities of electronic circuits, advanced circuits and processing units.
    -- Removed the previous requirement to use completed vanilla logistic chests as ingredients.
    -- The existing recipe-cost preset now controls both the original filtered 9x9 steel chest and all enabled logistic chest variants.
    -- Existing recipe-cost preset options remain:
      - Cheap
      - Standard
      - Rocket Silo equivalent

  Graphics:
    -- Added dedicated icons for the passive provider, storage, buffer and requester variants.
    -- Added a runtime tint mask for the logistic chest variants.
    -- Added distinct Factorio-style colours for each logistic mode.
    -- Darkened the runtime tint mask to preserve the original industrial metal shading, scratches and surface detail.
    -- Improved the visual distinction between the logistic chest variants.
    -- The normal filtered 9x9 steel chest remains untinted.
    -- The central robot hatch and excluded mechanical components remain unaffected by the logistic tint.

  Sounds:
    -- Added Factorio's built-in mechanical-large-open sound to the robot hatch animation.
    -- Added sound aggregation to prevent overlapping robot-door sounds from becoming excessively loud when several robots interact with the chest.
    -- Added the vanilla logistics chest opening sound as a fallback definition.
    -- No Factorio audio assets are redistributed with the mod; sounds are referenced from the installed base game.

  Settings:
    -- Added the startup drop-down setting:
      filtered-9x9-steel-chest-passive-storage-unlock
    -- Added the following internal setting values:
      - non_vanilla
      - vanilla
    -- The displayed drop-down choices are:
      - Non Vanilla - Logistic System Research
      - Vanilla
    -- One setting controls both the passive provider and storage variants together.

  Compatibility:
    -- Preserved optional Upgrade Planner compatibility with the vanilla Rocket Silo.
    -- Logistic chest prototypes are only created when their corresponding startup settings are enabled.
    -- Research unlock effects are added without creating duplicate unlock-recipe entries.
    -- Added defensive research fallbacks for overhaul mods that remove expected vanilla technologies.
    -- No runtime on_tick processing is used.

Version: 0.1.6
Date: 2026-07-23
  Features:
    -- provided a more inline icon

Version: 0.1.5
Date: 2026-07-23
  Features:
    -- rushed icon change, needed to make it with no white background, tried to provide a better icon, not 100% happy but its bit more inline with other chest icons

Version: 0.1.4
Date: 2026-07-23
  Features:
    -- realised actually a rocket silo is actually only 10 slots not 20, so I have aligned with the rocket silo, you can change this in the game mods settings up to 400 if you want. Remember quality does also increase what ever you set there in game.
    -- provide a better icon that makes more sense for a factorio menu and research icons

Version: 0.1.3
Date: 2026-07-23
  Features:
    - loss of cleanliness is mostly a rendering/downscaling problem due to a high quality 1254x1254 image. Unusually high amount of fine detail: thin panel seams, rivets, scratches, pipes, gear teeth, hazard stripes, text, and narrow highlights. In-game, Factorio is reducing all of that into a much smaller on-screen footprint. Many details become approximately 1 pixel or sub-pixel wide, producing the grainy/noisy/over-sharpened appearance visible in the first image.
    -- fixed the technology unlock and effects so it now chest correctly appears in the research as an effect
