v4.2.0

Minor Changes

• f61869a: createApi now accepts any axios-like HTTP client via a structural AxiosLike contract, not only a concrete AxiosInstance. Existing axios consumers are unaffected (an AxiosInstance still satisfies AxiosLike); fetch-style wrappers and other clients with their own config/response types are now assignable as well. The StringTrailingSlash URL brand is retained to guard against Django APPEND_SLASH redirects.
