Version bumps:

  • kotlinx.io -> 0.1.14 -> none

Breaking changes:

  • kotlinx.io dependency has been removed, replace imports:
    • import kotlinx.io. -> import io.ktor.utils.io.
    • import kotlinx.coroutines.io. -> import io.ktor.utils.io.
  • No binary compatibility with 1.2.x.
  • Incompatible Gradle metadata version (requires 5.4.1+ for MPP).
  • It was dangerous to forget call HttpResponse.close, so we cleaned it’s API:
    • HttpResponse isn’t Closeable anymore: no need to close it, no resource leaks
    • HttpResponse is in-memory by default
    • Introduced HttpStatement: new primitive for streaming and partial load

Known issues:

  • Netty HTTP/2 push sometimes get rejected
  • Running iOS and native clients on non-main worker is still not supported
  • JS engine may trigger CORS preflight (#1533)
