  • KTOR-9546 HttpClient: cancelling ByteReadChannel body does not propagate to engine
  • KTOR-455 Content-Disposition additional parameters should be inside quotes
  • KTOR-9500 RawSourceChannel returns false positive on awaitContent
  • KTOR-646 Netty engine still print annoying exceptions
  • KTOR-9527 Curl: Freeze when receiving large responses
