  • KTOR-9788 Netty: engine double-responds after its built-in 400, crashing the call-handler coroutine with "Headers can no longer be set because response was already completed"
  • KTOR-9834 HttpClient eagerly initializes SLF4J during Android startup
  • KTOR-9701 Jackson/Gson converters waste time on unnecessary Dispatchers.IO dispatch
