Also modify _nc_setupscreen() to avoid redundant calls to get original tty-modes. + modify set_curterm() to update ttytype[] data used by longname(). + modify wattr_set() and wattr_get() to return ERR if win-parameter is null, as documented. + improve cast used for null-pointer checks in header macros, to reduce compiler warnings. + modify several functions, using the reserved "opts" parameter to pass color- and pair-values larger than 16-bits: + getcchar(), setcchar(), slk_attr_set(), vid_puts(), wattr_get(), wattr_set(), wchgat(), wcolor_set(). + Other functions call these with the corresponding altered behavior, including chgat(), mvchgat(), mvwchgat(), slk_color_on(), slk_color_off(), vid_attr(). + add new functions for manipulating color- and pair-values larger than 16-bits. These are extended_color_content(), extended_pair_content(), extended_slk_color(), init_extended_color(), init_extended_pair(), and the corresponding sp-funcs.
ncurses 6.0 - patch 20170311 + modify vt100 rs2 string to reset vt52 mode and scrolling regions (report/analysis by Robert King) -TD + add vt100+4bsd building block, use that for older terminals rather than "vt100" which is now mostly used as a building block for terminal emulators -TD + correct a few spelling errors in terminfo.src comments -TD + add fbterm -TD + fix a typo in ncurses.c test_attr legend (patch by Petr Vanek). + changed internal colorpair_t to a struct, eliminating an internal 8-bit limit on colors + add ncurses/new_pair.h + add ncurses/base/new_pair.c with alloc_pair(), find_pair() and free_pair() functions + add test/demo_new_pair.c

ncurses 6.0 - patch 20150627 + modify configure script to remove deprecated ABI 5 symbols when building ABI 6. + add symbols _nc_Default_Field, _nc_Default_Form, _nc_has_mouse to map-files, but marked as deprecated so that they can easily be suppressed from ABI 6 builds (Debian #788610). + comment-out "screen.xterm" entry, and inherit screen.xterm-256color from xterm-new (report by Richard Birkett) -TD + modify read_entry.c to set the error-return to -1 if no terminal databases were found, as documented for setupterm. + add test_setupterm.c to demonstrate normal/error returns from the setupterm and restartterm functions. + amend cleanup change from 20110813 which removed redundant definition of ret_error, etc., from tinfo_driver.c, to account for the fact that it should return a bool rather than int (report/analysis by Johannes Schindelin).
