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

* ncurses		6.4-12.20230715
* ncurses-demo		6.4-12.20230715
* terminfo		6.4-12.20230715
* terminfo-extra	6.4-12.20230715
* libncurses-devel	6.4-12.20230715
* libncurses++w10	6.4-12.20230715
* libncursesw10		6.4-12.20230715

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, and no newer release
becomes available, this release will be promoted to current stable.

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
