+ 5.8 (Feb 26, 2011)
+ Interface changes:
+
+ + add an alternate library configuration, i.e., "terminal driver" to
+ support port to Windows, built with MinGW. There are two drivers
+ (terminfo and Windows console). The terminfo driver works on other
+ platforms.
+
+ + add a new set of functions which accept a SCREEN* parameter, in
+ contrast with the original set which use the global value "sp".
+ By default, these names end with "_sp", and are otherwise
+ functionally identical with the originals.
+
+ In addition to the "_sp" functions, there are a few new functions
+ associated with this feature: ceiling_panel, ground_panel,
+ new_prescr.
+
+ If the library is not built with the sp-funcs extension, there
+ are no related interface changes.
+
+ + add tiparm function based on review of X/Open Curses Issue 7.
+
+ + change internal _nc_has_mouse function to public has_mouse function
+
+ Added extensions:
+
+ + add a few more functions to support the NCURSES_OPAQUE feature:
+ get_escdelay, is_pad, is_subwin

+ _nc_curscr_of
+ _nc_format_slks
