    - Added direct-effect infinite research for character mining speed, crafting speed, walking speed, reach, and build distance.
    - Added direct-effect infinite research for character logistic trash slots.
    - Added per-stream research time startup settings.
    - Added max-level startup settings for generated base-tech extensions.
    - Added support for stream-provided custom icons and icon tinting.

  Changes:

    - Character Inventory Slot research now uses explicit utility, military, and agricultural science packs.

    - Base-tech extension research time settings now allow 0 to reuse the configured default.

Version: 1.2.0
Date: 2025-10-28

  Features:

    - Added infinite extensions for braking force, research speed, worker robot storage, inserter capacity, and weapon speed.
    - Added startup settings for enabling and tuning base-tech extensions.
    - Added direct-effect rocket, cannon-shell, flamethrower, and electric weapon shooting speed research.
    - Added max-level enforcement for generated infinite stream technologies.
    - Added vanilla weapon shooting speed adjustment support.
    - Dedicated generated speed researches can own selected vanilla weapon speed bonuses.

  Changes:

    - Added default cost and science-pack profiles for each generated base-tech extension.
    - Added dedicated locale keys and setting descriptions for base-tech extension settings.
    - Corrected the promethium science pack spelling in English locale text.

Version: 1.1.5
Date: 2025-10-27

  Features:

    - Added per-stream base cost, growth factor, and max-level defaults and startup settings.
    - Added English locale support for mod name, mod description, technology names, and setting text.
    - Added locale files for German, Spanish, French, Italian, Polish, Brazilian Portuguese, Russian, and Simplified Chinese.
    - Added direct-effect Character Inventory Slot and Worker Robot Battery research.
    - Added broad productivity coverage for science packs, infrastructure, weapons, intermediates, and Space Age materials.
    - Added grouped productivity streams for modules, belts, inserters, bullets, and rockets.

  Changes:

    - Added item prototype lookup for modules and science packs when selecting icons and matching outputs.
    - Added recipe exclusions for common unwanted scrap and asteroid byproducts.
    - Added Quality module coverage to Module Productivity.
    - Refined belt tiers to cover turbo and hyper transport belt families.
    - Rail Productivity now avoids unrelated rail-like outputs.
    - Added a startup gate setting for holding generated technologies behind space or promethium science.

Version: 1.1.0
Date: 2025-10-25

  Features:

    - Added support for hiding generated productivity research when Space Age provides the vanilla equivalent.
    - Added direct-effect technology generation support for non-productivity infinite bonuses.
    - Added early Character Inventory Slot and Worker Robot Battery infinite research.
    - Added early Science Pack, Wall, Grenade, Rail, Electric Energy, Concrete, Furnace, and Drill productivity.

  Changes:

    - Expanded item lookup for generated icons and recipe matching.
    - Item lookup can use ammo, capsules, modules, and science pack prototypes where appropriate.
    - Added Space Age-aware science-pack selection with optional promethium or space-science gating.

Version: 1.0.0
Date: 2025-10-25

  Features:

    - Initial public release for Factorio 2.0 with optional Space Age support.
    - Added generated infinite recipe productivity technologies for many intermediate items and resources.
    - Generated productivity technologies cover resources not covered by vanilla productivity research.
    - Added per-technology startup enable switches for every generated research stream.
    - Added automatic recipe scanning for covered outputs and generation of matching productivity effects.
    - Added conflict trimming so recipes already covered by existing productivity technologies are skipped.
    - Added Space Age-aware science-pack selection and prerequisites for generated technologies.
    - Added a default infinite research cost curve of `8000 * 2^(L-1)` with 60-second research units.

  Initial research coverage:

    - Added productivity streams for vanilla intermediates, infrastructure, ammunition, and science packs.
    - Added Space Age and overhaul-oriented productivity streams for advanced materials.
    - Added grouped productivity streams for modules, belts, inserters, bullets, and rockets.
    - Grouped productivity streams use lower per-level gains for higher-tier items inside those groups.

  Notes:

    - The technologies are intentionally infinite, but Factorio's recipe productivity cap still applies.
    - The mod was created to make megabasing easier on lower-end hardware.
    - The mod still preserves Factorio's normal production and logistics constraints.
