     you may encounter when building a system with different versions of
     ncurses:
 
+    6.3 (Oct 21, 2021)
+       Interface changes:
+
+       + the definition of TERMTYPE2 is now internal, not visible in the ABI,
+         like the enclosing TERMINAL which was previously made opaque.  This
+         was done to provide SCREEN-specific "static" variables in terminfo.
+
+       Added extensions:
+
+       + add sp-funcs for erasewchar, killwchar.
+
+       Added internal functions (other than "_sp" variants):
+
+       + _nc_safe_fopen and _nc_safe_open3 limit privileges if possible when
+         opening a file; otherwise disallow access for updating files.
+
+       + _nc_tiparm is a variant of tiparm which is used when all of the
+         parameters are known to be numbers rather than possibly strings.
+
+       + _nc_reset_tparm improves tic's checks by resetting the terminfo
+         "static variables" before calling functions which may update them.
+
+       Removed internal functions:
+
+       + none
+
+       Modified internal functions:
+
+       + _nc_trace_ttymode passes pointer to const data
+
+       + _nc_tparm_analyze passes pointer to int*, not int[]
