- Blocking read operations on the Windows Console can now EINTR - Blocking read operations on Windows pipes now EINTR more reliably - setitimer() will no longer be inherited across fork() on Windows - It's now possible to use ECHO when the console is in raw mode - The ECHOCTL flag now works correctly on the Windows Console - The ICRNL flag now works correctly on the Windows Console - pread() and pwrite() will now raise ESPIPE on Windows - Opening /dev/tty on Windows is improved (untested) - Overlapped I/O is now implemented in a better way
