+## 4.107.1
+**`(fix):`** Make OpenAPI validation errors non-fatal during docs generation. Previously,
+validation issues like "Self-referencing circular pointer" or parameter name
+collisions would abort `fern generate --docs` entirely. The CLI now logs
+warnings and skips the offending API workspace so the rest of the docs can
+still be published. These validations remain errors in `fern check`.

+## 3.66.5
+**`(fix):`** Fix generated wire tests for SSE endpoints with protocol-discriminated unions.
+The expected event assertion no longer wraps the deserialized data in a duplicate
+discriminant key (which produced TS2783 "specified more than once" errors under
+strict typecheck). When the example puts the discriminant inside the data payload
+and leaves the SSE event line empty, the discriminant is now promoted onto the
+event line before being stripped from the data, so the mocked wire body matches
+what the runtime SDK produces.

 ## 3.66.4
 **`(fix):`** Fix undiscriminated-union query parameters so the list variant is sent as
 repeated keys (`?key=a&key=b`) instead of a URL-encoded JSON blob. Mirrors
