Changelog

Version: 1.1.1
Date: 2026-09-30
  Bugfixes:
    - Fixed a crash when the mod was added to an existing save or when the mod list changed at all.
      on_configuration_changed aborted with "LuaGameScript doesn't contain key create_profiler"
      while resetting the road network, before any depot or drone logic ran.
    - Factorio 2.1 moved the profiler factory from the game object to helpers, so the road network
      reset now calls helpers.create_profiler().
    - 修复把模组加入已有存档（或任何模组列表变动）时的崩溃：重建公路网时
      on_configuration_changed 因 "LuaGameScript doesn't contain key create_profiler" 中断，
      其后的仓储与无人车逻辑完全没有机会执行。2.1 已把创建性能分析器的接口从 game 移到
      helpers，公路网重建现在改用 helpers.create_profiler()。

Version: 1.1.0
Date: 2026-09-30
  Info:
    - Requires Factorio 2.1. This is a port of the 1.0.27 code base: no gameplay rebalance was added,
      the entries below only make the mod work again on the 2.1 API.
    - 需要 Factorio 2.1。本次发布是把 1.0.27 的代码移植到 2.1，未追加数值平衡改动，以下内容只是让模组在 2.1 API 上重新可用。
  Major Features:
    - Transport depots update again. The update buckets were stored under indices 1..N but looked up
      with "tick % N", which yields 0, so on a new save no depot ever ran its update. Both sides now
      share one 1-based index, and the buckets are rebuilt on every load to repair affected saves.
    - 运输仓储重新开始工作。原先更新桶存放在下标 1..N，却用 "tick % N" 取值（结果含 0），导致新存档里没有任何仓储
      执行过更新。现在两侧统一使用 1 起始的下标，并在每次读档时重建更新桶以修复受影响的存档。
    - Request and buffer depots order items again. get_recipe() can return a nil quality on 2.1; that
      value was interpolated into the road network supply key, so every lookup missed and no drone was
      ever dispatched. A nil quality is now normalised to "normal".
    - 请求仓储与缓存仓储重新开始下单。2.1 的 get_recipe() 可能返回 nil 品质，它被拼进运输网络的供货键，导致每次
      查找都落空、永远不会派车。现在 nil 品质会归一化为 "normal"。
  Features:
    - The fluid depot, fuel depot and buffer depot now read and write their fluidboxes through a
      2.0/2.1 compatibility layer (get_fluid / set_fluid / get_fluid_capacity / get_fluid_box_neighbours),
      because LuaEntity::fluidbox was removed in 2.1.
    - 流体仓储、燃料仓储与缓存仓储改为通过 2.0/2.1 兼容层读写流体箱（get_fluid / set_fluid /
      get_fluid_capacity / get_fluid_box_neighbours），因为 2.1 移除了 LuaEntity::fluidbox。
    - The fluid request depot keeps its "push fluid into the connected pipe" behaviour, rewritten on top
      of the fluid box neighbour API, so the 1,000,000 unit output buffer still drains into a pipeline.
    - 流体请求仓储保留"向相连管道推送流体"的行为，并基于流体箱邻居 API 重写，因此 100 万单位的输出缓冲仍能排入管道。
  Balancing:
    - Nothing is rebalanced in this release. The fork's existing values (100% per transport speed level,
      fast fluid/fuel drones, cheaper technologies, steel-plate road) are unchanged.
    - 本次发布未做任何平衡调整。本分支原有数值（速度科技每级 +100%、更快的流体/燃料无人车、更便宜的科技、钢板公路）
      保持不变。
  Bugfixes:
    - assembler3pipepictures() no longer exists as a global in 2.1; the depot pipe pictures are now built
      from the base game's own pipe sprite definitions.
    - 2.1 移除了全局函数 assembler3pipepictures()；仓储的管道贴图改为用本体自带的管道贴图数据构建。
    - Recipes no longer use the removed "category" field; all five occurrences now use "categories".
    - 配方不再使用已被移除的 category 字段，共 5 处改为 categories。
    - LuaEntity::minable is read-only in 2.1, so the hidden supply depot chest now uses minable_flag,
      with a 2.0 fallback.
    - 2.1 中 LuaEntity::minable 变为只读，隐藏的供货仓储箱子改用 minable_flag，并对 2.0 保留回退。
    - LuaEntity::active is read-only in 2.1, so the depots no longer try to deactivate themselves and the
      fluid depot no longer toggles its own active flag.
    - 2.1 中 LuaEntity::active 变为只读，仓储不再尝试自我停用，流体仓储也不再切换自身的 active 标志。
    - defines.inventory.assembling_machine_input was removed in 2.1; the depot drone bay now uses the
      shared recipe inventory (lab_input), with a 2.0 fallback.
    - 2.1 移除了 defines.inventory.assembling_machine_input；仓储的车库改用统一的配方库存（lab_input），
      并对 2.0 保留回退。
    - Removed the stray script/gui.lua.bak and script/transport_drone.lua.bak development files that were
      shipped inside the 1.0.27 zip.
    - 删除了 1.0.27 压缩包内误带的 script/gui.lua.bak 与 script/transport_drone.lua.bak 开发残留文件。
  Modding:
    - info.json now declares factorio_version 2.1 and base >= 2.1.0, and re-declares the optional
      integrations (quality, space-age, apm_recycling, PickerDollies, alien-biomes, omnimatter).
    - info.json 现在声明 factorio_version 为 2.1、依赖 base >= 2.1.0，并重新声明各可选联动模组（quality、
      space-age、apm_recycling、PickerDollies、alien-biomes、omnimatter）。
    - Version bumped to 1.1.0 so the 2.1 build is distinguishable from the 1.0.27 2.0 build.
    - 版本号提升到 1.1.0，以便与 1.0.27 的 2.0 版本区分。
  Translations:
    - Added [mod-name] and [mod-description] entries for both the fork name and the upstream name, so the
      mod list shows the fork's own name in English and in Chinese.
    - 为分支名与上游名补充 [mod-name] 与 [mod-description]，使模组列表在中英文下都显示本分支的名称。
    - Added the missing English menu keys and the Chinese tip pages that were missing, so both languages
      cover every tip page.
    - 补齐英文缺失的菜单键，以及中文缺失的部分教程条目，使两种语言覆盖全部提示页。
    - Corrected the English speed technology description to +100% per level, matching the value the fork
      actually applies; it previously claimed +20%.
    - 修正英文的速度科技说明为每级 +100%，与分支实际生效的数值一致；此前写作 +20%。

    - Changed update logic so it has a fixed interval, within which all depots will be updated. It defaults to 60 ticks.
    - Added a runtime global mod setting to adjust this interval. Lower values mean more script update time, but the depots are more responsive. Higher values mean reduced UPS usage, at the cost of less responsive depots.

Version: 0.3.6
Date: 2020-04-11
  Changes:
    - Added a simple heuristic related to item count to the buffer selection function. This should help the situation of requesters always taking from the closest buffer even if it has a very small amount of available items.

Version: 0.3.5
Date: 2020-04-11
  Changes:
    - Fixed error trying to refund bad tile placement with Construction drones built tile event.

Version: 0.3.3
Date: 2020-04-09

    - Adjusted logic of requesting from buffers. Request depots should tend to request from nearest buffers more reliably.

Version: 0.3.2
Date: 2020-04-09
  Changes:
    - Fixed a script error when removing a depot which was holding a reference to a dead drone.

    - Supplying depots (supply, fluid, mining, buffer) will offer to the closest request depots first.
    - Fixed some issue with modded rails and gates not being placeable on roads.
    - Buffed fuel depot capacity to 10k.
    - Removed 'minimum request amount' logic.
