New curses is an emulation of Sys V R 4 curses, and more.
It uses and includes thousands of terminal definitions in terminfo
format, supports pads, color, multiple highlights, forms characters,
function key mapping, has all the other SVR4 curses enhancements
over BSD curses, plus terminal utilities, and demo programs packages.
For more information see the project home page:
https://invisible-island.net/ncurses
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.
The following test packages have been uploaded to the Cygwin distribution:
- ncurses 6.6+20260117
- ncurses-demo 6.6+20260117
