Patch Notes

What's changed in Sammy's Dino Habitat Planner. Newest first.

v1.6-test 2026-04-29 Working Build

Saved habitats + map images on cards

  • Save and load named habitat configurations — full member roster, M/F counts, seed, and habitat type all persist.
  • Save / Load / Delete controls live at the top of the habitat panel.
  • Map cards now show real in-game / wiki overview images where available (Montana, Biosyn, Malta, Indonesia, Azores, Isla Nublar, Isla Sorna). Maps without published screenshots show a biome-themed gradient.
v1.5-test 2026-04-29 Working Build

Maps tab (work-in-progress)

  • New Maps tab between Habitat Builder and Patch Notes — covers all 10 JWE3 campaign maps (Hawaii, Nevada, Montana/Fox Hills, Sichuan, Katsuyama, Indonesia, Biosyn Sanctuary, Malta, the Azores, Endgame) plus Isla Nublar / Isla Sorna sandbox.
  • Each map shows biome, climate, terrain emphasis, scenario notes, and a ranked list of best-fit species per habitat type (Land / Aviary / Lagoon).
  • Recommendations score each species via era affinity (+25 for matching era) + cosine similarity between the dino's environment % and the map's favored terrain (up to +25), on top of a 50 baseline.
  • Click any recommended species card to jump to its full Browse detail.
  • Sammy's logo wired into the topbar.
v1.5 2026-04-29 Feature

Recommended composition on Browse tab

  • Each species' Browse page now shows a "Recommended for full comfort" callout — concrete numbers like "1 male + 2 females = 3 adults total" instead of vague "1+" ranges.
  • Added the same JWE-style arrow-marker bars (Males / Females / Total) to the Browse detail so the visual is consistent with the Habitat Builder.
  • Required-range labels under each bar spell out what the in-game minimums and caps are.
v1.4 2026-04-29 Feature

JWE-style population bars + three-state status

  • Population Builder rows now show JWE-style horizontal bars with an arrow marker at each species' minimum threshold (Males / Females / Total). Left of the arrow = sub-optimal; right = fine.
  • Three-state status replaces the binary ok/bad: ✓ Optimal (all minimums met) · ⚠ Workable (below an optimal min but no caps violated — dino lives, just less comfortable) · ✗ Conflict (exceeds a hard cap; extras will fight).
  • Top habitat summary shows a colored "Population" tag matching the worst row.
  • Member cards now color-code by population status (green/yellow/red) instead of binary.
  • Added a Patch Notes tab.
v1.3 2026-04-29 Data

Real JWE3 sex-ratio data + per-species M/F controls

  • Imported per-species adult male / female / population minimums and caps for 73 species from the community-cataloged JWE3 Genome Library.
  • Builder rows now have −/+ controls for males and females per species. Defaults pre-fill to satisfy each species' minimums.
  • Confirmed entries: Carnotaurus 0-1 males · Utahraptor 0-1 females · Therizinosaurus 0-1 each · Giganotosaurus / Velociraptor / Oviraptor need 2+ females · Apatosaurus / Dilophosaurus / Suchomimus need 1+ males · hybrids (Indominus, Indoraptor, Scorpios, Spinoceratops, Spinoraptor, Stegoceratops, Ankylodocus) are sterile single-sex.
  • Marine, Aviary, and 4 DLC species (Concavenator, Guanlong, Protoceratops, Thanatosdrakon) still use family/size estimates marked with *.
v1.2 2026-04-28 Feature

Habitat Builder + problem-dino highlight

  • New Habitat Builder tab: pick a seed → see ranked compatible mates → review combined habitat needs.
  • Combined Environment Needs with conflict markers (some members don't share a need).
  • Required Feeders summary — JWE3's actual Rock / Sand / Meat / Goat / Fish / G+T-tier Fiber/Leaf/Fruit/Nut feeders, with overcrowding warnings.
  • Pairwise Compatibility matrix sorted worst-first with reasons.
  • Family Balance check against the JWE3 base-enclosure formula (1× Sauropod, 1× Ornithomimid/Pachy, 1× Hadrosaur, 1× Ceratopsid/Anky/Stego).
  • "Problem dino" pulse highlight — flags the member with the most low-scoring pairs.
  • Auto-detected enemy/friend lists collapse into clickable group pills (e.g., "Carnivore (group, 30)") to save space.
v1.1 2026-04-28 Fix

Cohabitation rules overhaul

  • Universal carnivore-rivalry rule baked into scoring — Allosaurus now correctly avoids other carnivores it doesn't explicitly tolerate, even when the source data lacked an explicit Dislikes entry.
  • Specific feuds added: ceratopsid sub-rivalries (Triceratops / Styracosaurus / Torosaurus / Sinoceratops / Pachyrhinosaurus), Tapejara ↔ Tropeognathus, marine size-based prefs.
  • Scavengers (Compsognathus, Coelophysis, Moros Intrepidus, Oviraptor) now implicitly tolerate each other and everyone else.
  • Hybrid apex predators (Indominus, Indoraptor, Scorpios) only tolerate explicit likes — everything else flagged "Avoid."
  • Likes data sourced canonically from IGN's JWE3 Cohabitation Guide.
v1.0 2026-04-26 Initial Release

Browse + compatibility scoring + JWE database art

  • Browse tab with all 124 JWE3 species (Land / Aviary / Lagoon).
  • Per-dino card: era, family, size, diet, environment %s, food preferences, likes/dislikes.
  • Compatibility scoring — environment cosine similarity + feeder Jaccard overlap, with carnivore-vs-herbivore predator-prey gating.
  • Live Wikipedia image fallback.
  • JWE Fandom database art for every species, downloaded locally to dodge Cloudflare hotlink protection.
