====================================================================

What's new:
-----------

- Drop support for Vista and Server 2008.

- Drop support for 32 bit Windows and WOW64.

- Allow to run with full ASLR enabled and enable on Cygwin DLL by default.

- Remove any special handling for the .com filename suffix. It has to
  be used always explicitely.

- Add code to handle setrlimit(RLIMIT_AS).

- Add code to handle signal masks in /proc/<PID>/status.

- Handle UDP_SEGMENT and UDP_GRO socket options.


What changed:
-------------

- The CYGWIN=pipe_byte option is now set by default, so that pipes are
  opened in byte mode rather than message mode.

- The stdio input functions no longer try again to read after EOF.
  This aligns Cygwin behavior to that of Linux.
  Addresses: https://cygwin.com/pipermail/cygwin/2022-June/251672.html

- Treat an empty path (empty element in PATH or PATH is absent) as
  the current directory as Linux does.
  Addresses: https://cygwin.com/pipermail/cygwin/2022-June/251730.html

- The default values of FD_SETSIZE and NOFILE are now 1024 and 3200,
  respectively.
