Changelog

Version: 1.5.2
Date: 11. 05. 2026
  Optimizations:
    - Bulk tile events now use a single union-area find_entities_filtered call when tiles are dense (≥8 tiles, ≥25% bbox density), falling back to per-tile scans otherwise.
  Bugfixes:
    - Fixed an issue where beacon would overload each other when within another's effect range.
    - Fixed an issue where beacons overload mechanics for modded playthroughs would not get properly removed (Beacon Rebalance).

Version: 1.5.1
Date: 10. 05. 2026
  Features:
    - Added support for Space Exploration and Beacons Rebalance mod. Beacon overload mechanics should now be handled among most other mods that modify this.

Version: 1.5.0
Date: 08. 05. 2026
  Features:
    - Added damage reduction cap setting (default limit 90%). Does not apply to friendly damage.
  Optimizations:
    - Batched chunk mark/unmark for tile placement and removal events; bulk landfill or concrete operations now scan each affected chunk at most once.
    - Entity searches around newly placed tiles now filter by force, skipping trees, rocks, particles, and enemy structures.
    - Throttled damaging area-of-effect near reinforced structures for performance improvements, each affected entity triggers at most one scan per second.
    - Removed redundant beacon search from the building-bonus hot path; orphan recovery now runs only on configuration changes.
    - Removed periodic tile-coverage rescan that was running surface.count_tiles_filtered for every multi-tile reinforced building each cycle; tile coverage is now strictly event-driven.
  Balancing:
    - Lowered default values for entity scan refresh rate and entities-per-scan to reduce idle overhead. Existing saves keep their previous values; new installs get the new defaults.
  Changes:
    - Tile and entity name patterns now use word-boundary matching so e.g. "stone" no longer matches "limestone" by accident. Use * (e.g. *stone*, wood-*, *floor) for substring or prefix/suffix matches.
    - Refactored the runtime control script into focused helper modules under scripts/ for damage handling, reinforcement checks, tile tracking, invulnerability overrides, selection indicators, beacon bonuses, and shared state/config setup.
  Bugfixes:
    - Buildings whose tiles get destroyed by area-of-effect weapons (e.g. atom bombs) no longer keep stale reinforcement bonuses.
    - Position-based fallback UIDs now include surface index, fixing health-tracking collisions for non-unit entities sharing a position across surfaces.
    - Player UIDs now use player index instead of name, avoiding stale entries on rename (for those who play offline/locally).
    - Fixed an issue where segmented enemies would receive damage reduction on tiles.
  Other:
    - Optional dependency for Concrete in Space to allow reinforcing of structures on platforms.
