Bug-reports and tests very appreciated.
You can visit CL-Ncurses's home page for more details and release notes.
I'll mention that ncurses is a version of curses, just so that people who search for "curses" will find this page. For the same reason, let me mention that this package could have been named cl-curses (especially since it's no longer ncurses-specific).
cl-ncurses uses UFFI which is much less portable than CFFI, for foreign bindings. Consider cl-charms or croatoan which provide CFFI bindings to curses.
