Changes for version 0.78 - 2021-01-21

    • Warn on attempts to ->connect to INADDR(6)_LOOPBACK as some OSes (e.g. OpenBSD) do not allow it
    • Various fixes for IO::Async::LoopTests to better support IO::Async::Loop::UV:
      • Insert some ->loop_once(0) calls between timing tests to allow libuv to clear its pending queues
      • Allow loops to declare that they cannot perform all-child PID watch and skip the relevant tests for it if so
    • Have $loop->later return a future instance if not passed any code (RT133240)
    • Accept more error codes for failure to resolve missing hostname (RT131109)
    • Defend against some undef values at global destruction time (RT132677)
