Test: ncurses/-demo terminfo/-extra libncurses/-devel/++/w10 6.5+20250823 (TEST) - Terminal display utilities, demos, terminal definition entries, development files, and runtime libraries

[Cygwin ncurses Maintainer]

The ncurses (new curses) library is an emulation of Sys V R 4
curses, and more. It uses terminfo format, supports pads, color,
multiple highlights, forms characters, function key mapping,
and has all the other SVR4 curses enhancements over BSD curses.

For more information see the project home page:

	https://invisible-island.net/ncurses

The following test packages have been uploaded to the Cygwin distribution:

- ncurses		6.5+20250823
- ncurses-demo		6.5+20250823
- terminfo		6.5+20250823
- terminfo-extra	6.5+20250823
- libncurses-devel	6.5+20250823
- libncurses++w10	6.5+20250823
- libncursesw10		6.5+20250823

Please test these packages as extensively as possible (especially if you
are a Cygwin package maintainer) as libncursesw10 is used in many
libraries including libreadline and utilities including less, vim,
emacs, most other editors, screen, tmux, mail and web clients, and bash.
Package maintainers should install this test release and rerun checks of
as many libraries and packages depending on libncurses{,++}w10 as
possible.
If no issues are reported in the next few weeks, this release may be
promoted to current stable.

For all the changes to multiple components since the previous Cygwin release,
see below or after installation read /usr/share/doc/ncurses/NEWS.
