 # @btravstack/entity
 
+## 0.7.0
+
+### Minor Changes
+
+- 5844dd4: `Entity.union(...)` returns a value, not a class.
+
+  ## Breaking: the class form is gone
+
+  ```ts
+  // before
+  class Payment extends Entity.union("method", [Card, BankTransfer]) {}
+
+  // after
+  export const Payment = Entity.union("method", [Card, BankTransfer]);
+  export type Payment = Entity.Instance<typeof Payment>;
+  ```
+
+  The class form typed as the members' shared _root_, not as the member union, so
+  it could not narrow — and it failed late, at the first call site that touched a
+  member-only field. A class's instance type cannot be a union (`TS2509`), so no
+  version of it could have narrowed; and its type was always redundant with the
+  root the author had already named. `class X extends Entity.union(...) {}` is now
+  `TS2507` at the declaration.
+
+  Statics that lived in the class body become plain functions:
+
+  ```ts
+  export const parsePayment = (row: unknown) => Payment.make(row);
+  ```
+
+  ## Breaking: `__base` is removed
+
+  The phantom `__base` carrier is gone from `EntityStatic` and `UnionMember`. It
+  existed only to compute the class form's root type. Nothing writes it by hand;
+  it is listed because it is part of the emitted public surface.
+
 ## 0.6.0
