Release Notes

openfeign/feign (io.github.openfeign:feign-httpclient)

v13.17

Compare Source

• Request now accepts a null Request.Body and treats it as "no body", instead of throwing a
  NullPointerException from body(), charset(), isBinary() and length(). A request with no
  body reports a null body and charset, is binary, and has length 0. Its toString() prints the
  request line and headers without a body (#​1210).
• Form encoders can process primitive array fields without failing on an Object[] cast.
  URL-encoded fields use the request's CollectionFormat. In multipart requests, numeric and
  boolean arrays create repeated parts, and byte[] values stay as one binary part. Multipart
  char[] values are still passed to the delegate encoder (#​3607).
