Changelog

Version: 1.0.6
Date: 2026-08-01
  Train Interiors:
    - Replaced the invisible train-wide interior power bus with one visible Locomotive Power Substation in every locomotive room.
    - Locomotive Power Substations provide 36 by 36 tile coverage and a 36-tile wire reach without changing vanilla Substations.
    - Only the persistent Main Locomotive Substation feeds the hidden Train Battery charger; other locomotive rooms must be connected with visible electric poles.
    - Expanded every locomotive pond to 12 by 4 tiles and added a centered 6 by 4 dry island for the fixed Substation and information Display Panel.
    - Substation guidance and the Main Train Battery Display Panel are hidden until the player selects the relevant entity.
  Bugfixes:
    - Fixed the Main Locomotive Display Panel repeatedly blinking and interrupting reading by using its stable half-tile position and applying its content only during creation or migration.
  Save Migration:
    - Existing saves remove legacy hidden interior taps, relay poles and per-wagon chargers while preserving stored Train Battery energy.
    - Existing player entities on newly required water or island tiles are preserved, including the supporting water beneath an existing Offshore Pump.
  Compatibility:
    - This release remains Base-game only. Locomotive Garden and every other Space Age-only feature remain excluded.

Version: 1.0.5
Date: 2026-07-31
  Features:
    - Added Nearby Ammo Count, three-level Wind Turbine progression, Minimal Wire, integrated FuelGlow, Gun Turret placement loading and repeated Ctrl+R area reloading.
    - Added optional deterministic Alien Biomes floor support for newly revealed natural Base/Nauvis cave terrain.
    - Added five-minute AFK kicking followed by a separate five-minute reconnect grace period and live Main Train recovery-body placement.
    - Added the Main Train 30-second defeat countdown and checkpointed in-save expedition restart.
  Train Interiors:
    - Added Train Interior Expansion Levels 8-10: 92x152, 92x212 and 92x272.
    - Rebalanced Train Battery, Train Interior Expansion, Main Train Expansion and Train Shield research costs to match The Cave 2.7.42.
    - Added the compact proximity entry prompt and clear Ctrl+Enter entry/exit instructions.
    - Train Shield upgrades are now numeric only and never replace, rotate or reconnect rolling stock.
    - Inter-wagon connector width now progresses 7, 15, 23, 31, 39, 47, 55, 63, 71, 79 and 87 tiles through Levels 0-10.
  Save Migration:
    - Existing saves extend each connector from its already researched Train Interior Expansion level by converting only previously void tiles above and below it.
    - Existing connector floor, player flooring, entities, machines, inventories, train rooms and transfer ports are preserved and never rebuilt.
  Performance:
    - Connector research is resolved once per map-void pass, removing the long apparent freeze during Train Interior Expansion completion.
  Bugfixes:
    - Increased Lamp Post power usage from 3 kW to 20 kW.
    - Replaced the corrupted west-facing Superheater sprite and truncated Armoured Biter attack-mask sprite sheet.
    - Added native pole fast replacement while preserving red and green circuit connections.
  Compatibility:
    - This release remains Base-game only. Space Age planets, official belt stacking, Stack Inserter, quality, spoilage, freezing and Locomotive Garden remain excluded.
    - Added an incompatibility with Fill4Me to prevent duplicate Gun Turret loading.

Version: 1.0.4
Date: 2026-07-26
  Features:
    - Added the tested Enemy Brood Split system to the standalone Base-game edition.
    - A killed vanilla Behemoth Biter releases one Big Biter, a Big Biter releases one Medium Biter, and a Medium Biter releases one Small Biter; the same one-unit chain applies to vanilla Spitters.
    - Small Biters and Small Spitters release nothing. Worms, Spawners, Armoured Biters and every non-vanilla enemy remain unchanged.
  Compatibility:
    - Released units preserve the killed unit's Force and spawn only at a nearby collision-free position.
    - Released units never repeat Coin or Ore Blood rewards. Tracking persists across Save/Load and Multiplayer and uses event-driven cleanup with no periodic scan.
    - No Space Age dependency, prototype, setting, graphic, enemy-generation rule or unrelated gameplay system was added or changed.

Version: 1.0.3
Date: 2026-07-26
  Bugfixes:
    - Mobile Factory and Control Room surfaces are now fully exempt from The Cave's repeated lighting enforcement. Permanent Night and Pitch Black no longer fight Mobile Factory's own interior lighting or cause rapid day/night flickering.
    - Existing saves restore the neutral surface properties previously overwritten by The Cave, including Always Day, minimum brightness, visual brightness weights, clouds and solar output.
    - Darkness Infestation now treats Mobile Factory and Control Room surfaces as safe interiors. Its warning, 30-second grace timer, threat growth and enemy waves are suspended and cleared while a player is inside.
  Compatibility:
    - The exemptions activate automatically only while Mobile Factory Space Age is installed in Base-game mode. Dimensional Ore and Dimensional Fluid integration is unchanged.

Version: 1.0.2
Date: 2026-07-25
  Bugfixes:
    - Fixed a non-recoverable Cave Collapse cleanup error caused by the old main-mod rendering namespace.
    - Collapse rendering cleanup now uses the active runtime mod name, so the standalone No Space Age edition no longer queries an inactive "the-cave" mod.

Version: 1.0.1
Date: 2026-07-25
  Bugfixes:
    - Fixed a non-recoverable error when a new player received the Starter Pack in the Base-only edition.
    - Removed the remaining runtime call to the deleted space_age_active() helper; Starter Pack entries now use Base-game prototype checks directly.

Version: 1.0.0
Date: 2026-07-25
  Major Features:
    - Created a standalone The Cave - No Space Age edition for Factorio 2.0 Base game.
    - Preserved the core cave, Train Interiors, Cave Collapse, Uranium Cave, Fortified Vault, market, coin, and research systems.
  Changes:
    - Removed all Space Age feature flags and declared a conflict with the Space Age mod and the main The Cave edition.
    - Removed official belt stacking, Stack Inserter progression, Turbo loader/reach tiers, planet regions, Locomotive Garden, quality items, and expansion-only rewards.
    - Rebuilt Market, Starter Pack, cavern loot, and Fortified Vault loot for Base-game prototypes.
    - Converted Advancing Collapse to Base/Nauvis zone palettes only.
    - Added defensive prototype cleanup for expansion-gated properties.
  Bugfixes:
    - Includes the Train Interiors fixed-layout anchor correction from The Cave 2.7.11, preventing existing interiors from shifting when rolling stock is added to the front of a train.
