## 1.46.3

**`(fix):`** Generated `raw_client.go` now sets `ResponseIsOptional: true` in `CallParams` for endpoints
whose success response body is optional — e.g. an operation that returns both a body-bearing
2xx and a 204 No Content. Previously the field was never emitted, so a real 204 (empty body)
hit `io.EOF` in the caller and surfaced as an error instead of a successful, nil-bodied
response.
