+This is a terse description of the new features added to readline-5.1 since
+the release of readline-5.0.
+
+1. New Features in Readline
+
+a. The key sequence sent by the keypad `delete' key is now automatically
+ bound to delete-char.
+
+b. A negative argument to menu-complete now cycles backward through the
+ completion list.
+
+c. A new bindable readline variable: bind-tty-special-chars. If non-zero,
+ readline will bind the terminal special characters to their readline
+ equivalents when it's called (on by default).
+
+d. New bindable command: vi-rubout. Saves deleted text for possible
+ reinsertion, as with any vi-mode `text modification' command; `X' is bound
+ to this in vi command mode.
+
+e. If the rl_completion_query_items is set to a value < 0, readline never
+ asks the user whether or not to view the possible completions.
+
+f. New application-callable auxiliary function, rl_variable_value, returns
+ a string corresponding to a readline variable's value.
+
+g. When parsing inputrc files and variable binding commands, the parser
+ strips trailing whitespace from values assigned to boolean variables
+ before checking them.
+
+h. A new external application-controllable variable that allows the LINES
+ and COLUMNS environment variables to set the window size regardless of
+ what the kernel returns.
