+## 5.49.2
+**`(fix):`** `infer-discriminated-union-base-properties` now lifts properties that every variant inherits via a shared `allOf $ref` parent. Previously these were dropped to protect TypeScript's `_Base` from colliding with the real parent interface, which left Go and C# unions missing common fields like `id`, `name`, and `display_name`.

+## 3.72.4
+**`(fix):`** The TypeScript SDK generator now suppresses lifted base properties from a discriminated union's synthesized `_Base` interface when every variant already inherits them via its `extends` chain. Pairs with the parser change that lifts shared-parent properties so non-structural-typing SDKs (Go, C#) can expose them; keeps the TypeScript output stable and avoids TS2320 collisions on optionality.
