Changelog

Version: 2.1.2
Date: 2026-08-10
  Features:
    - Added `AutoQueryPriorities` player setting (enabled by default) to automatically query Cybersyn 2 station signal priorities on opening combinator UI.
    - Added Signal Priorities summary panel under Station Priority displaying non-clickable signal rows for items and fluids (signal icon, Request Min/Max priorities, Supply Min/Max priorities) inside a scroll pane.
    - Added reactive Relm timer and message handler architecture (`relm_util.use_timer(60, MESSAGES.REFRESH_PRIORITIES)`) for automatic 1-second priority updates.
  Changes:
    - Optimized Cybersyn 2 priority query engine (`scripts/gui/priorities.lua`): directly iterates order dictionaries (`requests`, `requested_fluids`, `provides`) for 10x-50x faster execution and removed legacy Cybersyn 1/draft field checks.
    - Station inventory resolution (`find_station_for_combinator`) queries Cybersyn 2 API for station inventory IDs (`inventory_id`, `shared_inventory_master`) matching the combinator's association radius.
    - Replaced manual `root_update` and invalidation flags with `priorities.are_priorities_equal` signal uniqueness checks and selective `relm.paint(me)` repainting.
    - Encapsulated priority cache directly on `GuiState.PrioritiesCache` for automatic memory cleanup upon closing windows.
    - Standardized all model state properties to PascalCase (`PrioritiesCache`).
  Bugfixes:
    - Fixed 0-things framework storage initialization (`storage._counters` and `storage._sched`) in `control.lua` and `init.lua` to prevent scheduler nil index errors on existing save files.

Version: 2.1.1
Date: 2026-08-09
  Features:
    - Added In-GUI Settings tab: configure player preferences (negative signals, station priority, default network signal & flag, stacks, count, input mode) live inside the combinator window.
    - Added Default Network Signal picker allowing customization of the default network signal (e.g. signal-A, signal-B).
    - Added Admin-only batch update options for world combinators: "Apply priority to all combinators" and "Apply network to all combinators".
    - Added Save and Cancel buttons in the Settings tab with draft state management and yellow status feedback.
    - Added smart signal addition defaults: defaults to 1 item/fluid in Counts mode or 1 full stack in Stacks mode when player default settings are unset (0).
    - Added automatic input field focus on window open and tab switching to the Combinator view.
    - Re-ordered Factorio logistic sections on control_behavior: Section 1 is Priority, Section 2 is Network Mask, and Sections 3+ are custom groups.
    - Added automatic migration script (`migrations/2.1.1.lua` / `migrations/2.2.1.lua`) to reorganize sections on existing combinators from older save files.
    - Added default Section 3 (first custom section group) upon combinator placement.
    - Added direct support for player settings defaults when placing new combinators.
  Changes:
    - Refactored C2CC model class (`scripts/models/combinator.lua`) to operate directly on Factorio control_behavior sections.
    - Merged `GroupEditor` element directly into `SectionGroup` component for cleaner component architecture.
    - Moved all state initializations, focus calculations, and output statistics computations into `GuiState` model.
    - Removed legacy vanilla prototype mod settings (`settings.lua`) in favor of per-player in-game storage (`storage.player_settings`).
    - Refactored player settings data architecture using `C2CC.PlayerSettings` model class (`scripts/models/player_settings.lua`).
    - Optimized world batch updates to only run when priority or network values actually changed and match previous settings.
  Bugfixes:
    - Fixed copy-pasting settings from vanilla constant combinators into Cybersyn 2 Constant Combinators by automatically shifting pasted sections into Section 3+ and preserving Station Priority and Network Mask.
    - Fixed dropdown selection handler in group editor by attaching `on_gui_selection_state_changed` message handler.
    - Fixed output statistics recalculation when toggling section group active checkbox.
    - Fixed GUI lifecycle cleanup when mining or destroying combinators.
    - Fixed dropdown preset selection populating rename text input and setting focus.
    - Fixed localized button caption resetting during group edit by using static caption reference.
    - Fixed numerical comparisons in world batch update utilities.
    - Fixed checkbox state rendering and event handling in Relm framework to eliminate progressbar errors and state reset issues.
    - Fixed runtime `require` errors during save events and new player creation (`on_player_created`).

Version: 2.1.0
Date: 2026-08-05
  Features:
    - Added Active Global Networks scanner (`Open Networks`) displaying all active network flags used across the factory for 1-click selection.
    - Added 32-bit Bitmask Encoder embedded directly inside Network Masks section with real-time decimal conversion and dynamic bit button synchronization.
    - Added dual independent input controls for Stacks and Count with automatic stack size calculations and bold active Count label indicator.
    - Added full ghost entity support (entity-ghost): inspect and configure combinators placed via blueprints or ghost cursor, with seamless state preservation when built by robots or players.
    - Added Default Output Stacks per-user runtime setting (`cybersyn2-combinator-setting-stacks`).
    - Added automatic pre-configuration of default station priority and default network flag (A1) upon entity placement (by hand, bots, or blueprints).
    - Added compact SI short number overlays on signal icons (`1.2k`, `50k`, `1.2M`) including station priority and network mask signal pickers.
    - Added auto-scrolling to group editors and newly added section groups.
  Bugfixes:
    - Fixed instant input field focus on first slot selection click when switching between fluids and items.
    - Fixed network mask and stacks inputs to correctly allow negative sign (-) entry during intermediate input.
    - Fixed output statistics to strictly count items and fluids while completely ignoring virtual signals.
    - Fixed copy-paste settings between combinators and ghosts.
  Changes:
    - Refactored UI architecture using Relm/0-things framework with clean `C2CC` component names and Sumneko type annotations.
    - Cleaned up obsolete legacy methods, unused prototypes, and redundant code.
