See the Single UNIX Specification, Version 2 :

Also, add the functions :
use_default_colors();
assume_default_colors(fore, back);
(from ncurses) that allow the terminal default colours or user-specified
default colours to be used.
* Modified __init_getch to use termcap handle that has been allocated
(_cursesi_genbuf) instead of refetching it.
* Make wgetstr support erase - this is not a full blown SUSv2 version
but it is a start.
Add extra KEY_* definition.
Wrap definition of 'bool' with "#ifndef __cplusplus".
Add __attributes(...) to *printw() and *scanw().
Add wnoutrefresh()/doupdate() definitions.
* Added code to __restartwin to restore meta and cursor visibility states
* Added code to __stopwin to disable meta.
* Added the *line group of functions for drawing character lines.
* Added function derwin.
* Added function copywin.
* Modified both overlay and overwrite to use copywin.
* Updated man page with new functions and fixed minor format glitch.
* Added Bill's fixes for errors when compiling with WARNS=1
* Incorporated fixes to make usage of unctrl consistent in debug and
made improvements to ctrace - it now timestamps it's output better.
* Reduced the number of mallocs done by __init_getch by allocating key
structs in bunches instead of singly.
* Removed the shadowing of global declarations in newwin and subwin
functions
(this is a requirement of SUSv2) - the old macro behaviour can be
restored by defining _CURSES_USE_MACROS.
Changed function prototypes to use ANSI style.
All externally visible functions now have ANSI style declarations.
Add background manipulation functions.
Add def/reset_prog/shell_mode().
Remove __TERMATTR.
Tidy up tab vs. space.
Macros get...y and get...x are now functions.
Private functions/variables moved to curses_private.h
Replace character/attribute definitions from curses_private.h
screen update problems (particularly on the pmax, sparc and alpha,
and i386 to a lesser extent). It seems that because __LDATA wasn't a
fully packed structure (and hashes to check for screen updates hashed
unused areas in the structure as well) that under some circumstances the
compiler filled the unused areas with garbage.
Doesn't break binary compatibiliy - no shared library version number
changes.
