Changelog

Version: 0.1.27
Date: 2026-03-31
  Changes:
    - Added startup settings to scale the Sails Boats technology research cost.
    - Added startup settings to scale the production recipe costs of Sloope and Frigatte.

Version: 0.1.26
Date: 2026-03-09
  Fixes:
    - Silenced the hidden Frigatte waterway engine more aggressively by removing remaining exhaust-related sounds, triggers, and burner pollution visuals.
    - Removed the detached `light-smoke` puff from Cargo Ships `boat_engine` as a fallback for older waterway ship states.

Version: 0.1.25
Date: 2026-03-09
  Fixes:
    - Fixed a runtime crash in the legacy waterway Frigatte engine repair by iterating Factorio surface tables with `pairs(...)` instead of `ipairs(...)`.

Version: 0.1.24
Date: 2026-03-09
  Fixes:
    - Added runtime repair for existing waterway Frigatte trains that still carry a legacy Cargo Ships `boat_engine` and therefore keep emitting train-like steam.

Version: 0.1.23
Date: 2026-03-09
  Fixes:
    - Disabled all hidden waterway engine emissions on Frigatte to remove the detached train-like steam puff beside the ship.

Version: 0.1.22
Date: 2026-03-09
  Graphics:
    - Disabled funnel smoke on Sloope and Frigatte.
    - Disabled funnel smoke on the Cargo Ships waterway engine used by Frigatte.

Version: 0.1.20
Date: 2026-02-26
  Fixes:
    - Fixed stale enter and exit state lock cleanup so the custom ENTER key logic cannot interfere with a later vehicle state change on the next tick.
    - Backfilled boat name registration in runtime state for older saves if the boat-name table already existed.
  Optimizations:
    - Cached wind settings and refresh them only on init, configuration changes, and runtime setting changes instead of reading settings on every tick.
    - Skips waterway frigatte train scans when the wind ratio is unchanged and no speed update is needed.

Version: 0.1.19
Date: 2026-02-25
  Fixes:
    - Moved Sloope and Frigatte items and recipes to the Logistics > Transport subgroup so they no longer create or use the Unsorted crafting tab.
    - Added explicit item and recipe ordering to keep them grouped with other boats and vehicles.

Version: 0.1.18
Date: 2026-02-21
  Fixes:
    - Fixed wind speed logic for waterway frigatte trains so wind is now applied as a delta relative to the previous wind value and no longer causes cumulative exponential speed drift.
    - Added missing locale entries for wind-related runtime settings.
    - Cleaned the release package content by removing macOS metadata files from the archive.

Version: 0.1.17
Date: 2026-02-20
  Fixes:
    - Minor fixes.

Version: 0.1.16
Date: 2026-02-19
  Fixes:
    - Frigatte and Sloope steering fixes.

Version: 0.1.15
Date: 2026-02-15
  Graphics:
    - Frigatte shadow fixes.

Version: 0.1.14
Date: 2026-02-14
  Graphics:
    - Frigatte shadow update.

Version: 0.1.13
Date: 2026-02-09
  Changes:
    - Added a waterway version of frigatte integrated with Cargo Ships.
    - Building sails-frigatte on a waterway now converts it to an automated rolling-stock ship.

Version: 0.1.12
Date: 2026-02-07
  Graphics:
    - Icon fixes.

Version: 0.1.1
Date: 2026-02-02

    - Fixed animation.

Version: 0.1.0
Date: 2026-02-01
  Fixes:
    - Fixed a crash on init by defensively initializing the global table.
    - Fixed waterway frigatte rotated sprite layers by removing the empty.png shadow layer.
  Changes:
    - Added a custom input (default ENTER) to enter and exit Sails Boats with increased range.
    - Added runtime-global settings for enter and exit distance.
    - Added minimal fuel usage for wind-powered frigatte and sloope boats.
    - Added optional wind simulation that affects speed through runtime-global settings.
