==========================================================================
                   IMPORTANT DEPRECATION NOTES
==========================================================================

- Cygwin 3.3 is the LAST major version supporting

  - Windows Vista
  - Windows Server 2008

- Cygwin 3.3 is the LAST major version supporting 32 bit installations.

  If you're using 32 bit Cygwin in WOW64 on 64 bit machines, consider
  to move to a real 64 bit Cygwin installation in the next couple of
  months.

  If you're using 32 bit Cygwin on real 32 bit hardware or on WOW64 on
  ARM64, don't be alarmed.  The current installations including all
  Cygwin 3.3.x versions will continue to run on your system.  You just
  wont get any more updates starting with Cygwin 3.4.0.

- Cygwin 3.4, which will probably be release at some point in 2022,
  will be the LAST version supporting

  - Windows 7
  - Windows Server 2008 R2
  - Windows 8
  - Windows Server 2012

There are no plans to deprecate support for 64 bit systems starting with
Windows 8.1 / Windows Server 2012 R2 any time soon.
