+	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:

+	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.
