Changelog

Version: 1.6.3
Date: 2026-06-14
  Bugfixes:
    - Fixed Moshine being indirectly blocked by Coal Liquefaction requiring Myridian science.
    - Fixed Cerys being blocked by Myridian Frontier Survey instead of staying on the Fulgora/Cerys branch.
    - Fixed Vesta being blocked behind Rubia, Paracelsin, and Planet Crucible.
    - Fixed Rubia and Planet Crucible requiring Viridion science before Viridion science could be produced.
    - Fixed the release-validation guard so Planet Crucible may correctly stay after Rubia without being treated as an impossible Crucible prerequisite.
    - Fixed Lemures, Dea Dia, and Prosephina mutual discovery loops.
    - Fixed Aquilo/Pelagos bootstrap helpers such as asteroid reprocessing, captivity, fish breeding, and Pelagos exit support being pulled behind Myridian science.
    - Fixed Shattered Planet disappearing when the dependency's only endpoint was the Shattered Planet Approach marker.
    - Protected Moshine maglev, Panglia focused gun turrets, transport belt capacity, lightning collector, personal roboport MK2, energy shield MK2, advanced asteroid processing, module 3, coal liquefaction, captivity, and fish breeding from unnecessary Myridian or later chapter science gates.

Version: 1.6.2
Date: 2026-06-14
  Bugfixes:
    - Fixed Solara-local worlds and support technologies such as Moshine and Panglia being compressed behind Myridian science.
    - Protected Biolab, Cliff Explosives, Artillery, Tesla Turret, Rocket Turret, and related first-three-planet utility/combat technologies from Myridian or later chapter science gates.
    - Added validation so Solara-local technologies cannot be pushed behind Tellus, Pelagos, Aquilo, Myridian, or later chapter science again.
    - Reduced visual crossing between Frozeta, Castra, and the Pyraxis System label in remote view.
  Changes:
    - Folded the Pyraxis hazard-cluster layout polish into the 1.6.2 release line.
    - Polished the Pyraxis hazard cluster so Secretas, Frozeta, Foliax, Tiber, Tenebris, and Castra wrap around the Pyraxis System as a cleaner orbital crescent.
    - Kept all Pyraxis routes, unlocks, science requirements, and dependencies unchanged.

Version: 1.6.1
Date: 2026-06-14
  Bugfixes:
    - Protected core utility technologies such as Stack/Bulk Inserter from late IPO chapter science compression.
    - Removed Tellus, Pelagos, Aquilo, cryogenic, and later chapter science requirements from standard first-three-planet utility unlocks whose recipes still use ordinary materials.
    - Added release validation so these core utility unlocks cannot be pushed behind Myridian, Viridion, Pyraxis, Terminus, or late planet science loops again.
  Changes:
    - Kept chapter science integration and route/starmap geometry unchanged from 1.6.0.

Version: 1.6.0
Date: 2026-06-12
  Major Features:
    - Added the System Science Integration pass so IPO system science packs now pull in real chapter-world outputs when those planet packs are present.
    - Added chapter reward technologies for Solara, Myridian, Viridion, Pyraxis, and Terminus so each system science pack now gates a visible mastery reward.
    - Upgraded the IPO Campaign Board into an objective board that shows required anchor worlds, support worlds, system science status, chapter reward status, and the next unlock target.
  Changes:
    - System science recipes still keep their chapter milestone role, but now add safe world-specific ingredients from the matching chapter instead of being only vanilla science-pack bundles.
    - Added guarded ingredient discovery for supported planet science packs and signature materials, with fallbacks so missing optional outputs do not break data loading.
    - Added a 1.6.0 progression audit guard for chapter reward technologies and their chapter science requirements.
    - Updated the Mod Portal description to clarify that IPO is a curated non-K2SO Space Age planet-pack campaign organiser, distinct from heavier K2SO mega-pack bridges.
  Bugfixes:
    - Added duplicate protection for dynamically-added system science recipe ingredients.
    - Kept survey technology costs stable while changing only the crafted system-pack recipes and new reward technologies.

Version: 1.5.0
Date: 2026-06-07
  Major Features:
    - Released the Pyraxis Expansion Pass, expanding the Pyraxis hazard branch with Castra, Tenebris, and Tiber support.
    - Added curated compatibility for Castra, Tenebris Prime, and Factorio Tiberium as Pyraxis hazard-branch worlds.
  Changes:
    - Reworked Pyraxis routing so the slipstream has a single local entry connection.
    - Arranged the Pyraxis hazard worlds into a wrapped local cluster around the Pyraxis System.
    - Added asteroid spawn definitions to IPO-authored slipstream and interstellar routes where needed.
    - Reworked Pyraxis progression to keep Frozeta as the local gateway while Castra anchors the Tenebris and Tiber branch.
  Bugfixes:
    - Protected Frozeta, Secretas, Foliax, Castra, Tenebris, and Tiber discovery technologies from late science-compression loops.
    - Protected Aquilo from being pulled behind Tiber, Castra, or Tenebris progression.
    - Pruned stale direct Pyraxis route pairs so old saves cannot keep bypass routes into the new branch.

Version: 1.4.5
Date: 2026-06-03
  Changes:
    - Moved the Myridian cold-frontier order to Tellus -> Pelagos -> Aquilo, matching the default Tellus/Pelagos startup settings that make those worlds prerequisites for Aquilo.
    - Kept Pelagos as the branch point for Vesta and the Terra Palus -> Shchierbin -> Corrundum -> Cubium detour.
    - Shortened and pulled in the Corrundum -> Cubium detour so Cubium no longer sits over the Myridian Slipstream marker.
  Bugfixes:
    - Protected Tellus, Pelagos, and Aquilo discovery technologies from late-world Rubia/Crucible/cryogenic-style science loops.
    - Protected the early cold gateway technologies from IPO science compression.
    - Pruned stale Aquilo-first route names and route pairs so old saves cannot keep Myridian Slipstream -> Aquilo or Aquilo -> Tellus bypasses.

Version: 1.4.4
Date: 2026-06-02
  Bugfixes:
    - Fixed Aquilo discovery being pulled behind impossible Rubia/Crucible late-world science loops from optional planet science packs.
    - Protected Aquilo discovery from IPO science compression so Aquilo remains the first Myridian entry target.
    - Added a release validation guard for the Aquilo entry contract.
  Changes:
    - No starmap route geometry changes.

Version: 1.4.3
Date: 2026-05-31
  Locale:
    - Added Russian locale coverage contributed by the community for IPO technologies, science packs, space locations, tips-and-tricks pages, settings, and the Campaign Board UI.
    - Added Russian locale coverage for the Crucible approach helper labels.

Version: 1.4.2
Date: 2026-05-26
  Changes:
    - Moved the first outer-board entry from Fulgora -> Viridion Slipstream to Fulgora -> Solara Slipstream so Solara is the first intended post-Fulgora interstellar stop.
    - Preserved the downstream slipstream backbone as Solara -> Myridian -> Viridion -> Pyraxis -> Terminus.
    - Added asteroid spawn definitions to IPO-authored slipstream and interstellar routes by cloning appropriate Space Age route profiles, so the routes are no longer empty transit lanes.
  Bugfixes:
    - Pruned stale Fulgora -> Viridion bypass routes so old saves cannot skip Solara after migration refresh.

Version: 1.4.1
Date: 2026-05-26
  Bugfixes:
    - Updated the Forgeworks Core dependency baseline to forgeworks-core >= 0.2.4.
    - Corrected Shattered Planet icon namespace handling so IPO references skewer_shattered_planet directly instead of the separate asset-pack namespace.
  Changes:
    - Polished Terminus/Shattered Planet lane cleanup so Shattered Planet Approach no longer overlaps Terminus Slipstream and duplicate dependency aliases stack into one visible endpoint.
    - Kept the 1.4.0 Campaign Board feature set unchanged.
    - Kept the accepted 1.2.0 public starmap frozen: no route rewrites, no hub movement, and no new route geometry.

Version: 1.3.0
Date: 2026-05-24
  Major Features:
    - Added the Terminus Endgame Bridge as the first public 1.3.x progression feature.
    - The bridge sits after Survey: Terminus Deep Space and acts as a readable final gate for omega, Nexus, singularity, transceiver, wormhole, stargate, void, and other finale-style technologies when those technologies are present.

    - Kept Cerys as Fulgora -> Cerys only.
    - Kept Aquilo inside the Myridian route chain.
    - Kept Planet Crucible behind the Foliax -> Crucible Orbit/Approach -> Planet Crucible gate.
