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.

- Treat an empty path (empty element in PATH or PATH is absent) as
the current directory as Linux does.

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

Bug Fixes
---------
- Don't error out if getfacl(1) is called on a socket file.
Partially addresses: https://cygwin.com/pipermail/cygwin/2022-July/251768.html
- Make serial ioctl(TIOCMBIS/TIOCMBIC) work on USB CDC devices.
Addresses: https://cygwin.com/pipermail/cygwin/2022-November/252443.html
- Fix a SEGV when running a process with changed primary group.
Addresses: https://cygwin.com/pipermail/cygwin-apps/2022-September/042245.html
- Fix primary group handling when running a process tree containing
non-Cygwin processes and with changed primary group. The Cygwin child
process of a non-Cygwin process will have reverted its primary group
to the default primary group erroneously.
Addresses: https://cygwin.com/pipermail/cygwin-apps/2022-September/042245.html
- Fix parsing Windows command line when non-ASCII chars are in the input.
