+## Status: V1.1 (tag `v1.1`, 2026-10-01)
+
+Changes since V1, each validated in game against UE 4.27 on an identical play path:
+
+- **Text search fix (CX-B12).** In UE 5.5, searching for an *empty* substring reports a match at position 0, whereas
+  UE 4.27 reported no match. Blueprint `Contains`, `Split` and `Find Substring` nodes therefore behaved differently
+  (for example, face morph filtering let every morph through). 385 nodes in 28 Blueprints now call
+  `LPStringCompat` functions that keep the UE 4.27 behaviour. Runtime errors per character went back to UE 4.27
+  levels (session errors 30 → 7, out-of-bounds reads −22 %).
+- **Deprecated nodes replaced.** 56 `Get SkeletalMesh` and 6 `GetRandomPointInNavigableRadius` nodes (same
+  behaviour, non-deprecated calls): Blueprint compilation and cooking now report **0 warnings**.
+- **StreetMap verified.** All 280 cities (roads, buildings, amenities) and their 280 static meshes are identical to
+  UE 4.27; the smaller files come from the UE5 asset format, not from data loss.
+- **Shipping build.** The Shipping configuration builds and was played without issue, with the same layout as the
+  original releases (loose files, no `.pak`, so the game stays moddable).
+- Issues found during testing that also exist in UE 4.27 are documented in the error register and left unchanged.
+
 ## Status: V1 (tag `v1.0`, 2026-09-30)
 
 - The `LifePlayEditor` target compiles with no errors; every Blueprint loads and compiles.
