 ** Miscellaneous
+*** ~org-table-to-lisp~ no longer checks if point is at a table
+The caller is now responsible for the check.  It can use, e.g.,
+~org-at-table-p~.
+
+The function is also much more efficient than it used to, even on very
+large tables.
 *** New function : ~org-collect-keywords~
 *** Drawers' folding use an API similar to block's
