The ncurses (new curses) library is a freeware emulation of System V Release 4.0 curses. It uses terminfo format, supports pads and color and multiple highlights and forms characters and function-key mapping, and has all the other SYSV-curses enhancements over BSD curses. The distribution includes the library and support utilities, including a terminfo compiler tic, a decompiler infocmp, clear, tput, tset, and a termcap conversion tool captoinfo. Full manual pages are provided for the library an
major feature: These notes are for ncurses 6.0, released August 8, 2015. This release is designed to be source-compatible with ncurses 5.0 through 5.9; providing a new application binary interface (ABI). Although the source can still be configured to support the ncurses 5 ABI, the intent of the release is to provide extensions which are generally useful, but binary-incompatible with ncurses 5: Extend the cchar_t structure to allow more than 16 colors to be encoded. Modify the encoding of mouse state to make room for a 5th mouse button. That allows one to use ncurses with a wheel mouse with xterm or similar X terminal emulators.
